Title: Carriage/actuator assembly
Inventor: ANDERSON JAMES C
IPC: G11B5/56
Filed: 1999-06-22
Abstract: PROBLEM TO BE SOLVED: To reduce the mass of a carriage/actuator assembly for head provided with a servo mechanism for positioning the track in a magnetic tape device. SOLUTION: The carriage 24 mounting the head 18 is vertically moved along guide rails 26, 28 by a voice coil motor arranged under a plate 36. Since the carriage 24 is partially digged into the voice coil motor inside as shown in the figure, the centroid of the carriage 24 is positioned near the center of the force impressed by the voice coil motor. Thus, the counter-weight required for preventing the shaking of the carriage 24 due to this force is extremely reduced by making both of these positions coincide, and the servo system with good responsiveness is obtained accordingly.

Title: Automatic answering telephone set
Inventor: SAKAI YASUMASA
IPC: H04M1/64
Filed: 1989-07-10
Abstract: PURPOSE:To complete the purpose of a call only with a reply message depending on an opposite party and to attain delicate reception by using a DTMF(Dual Tone Multi-Frequency) signal after line connection so as to identify the opposite party and replying with a response message in response to the said opposite party. CONSTITUTION:When an incoming call comes from an opposite party and the line is connected, a reply message 20 is started for transmission. When a #signal is sent, a DTMF signal is converted into a code and stored in a RAM 4. When no # signal is sent, the communication is terminated. When a * signal is sent, the number stored in the RAM 4 is read. Then the said reply message is read from RAMs 21-24 storing the reply message of the opposite party in response to the number and sent to a telephone line 1 through a network controller NCU 2. When it is discriminated that the relevant number does not exist, the communication is terminated without further processing. However, the initial reply message is being sent in this case. Moreover, when no DTMF signal comes, only the initial reply message is sent.

Title: Current differential relay
Inventor: KURIHARA HAJIME
IPC: H02H3/28
Filed: 1996-06-14
Abstract: PROBLEM TO BE SOLVED: To make it possible to prevent a malfunction and keep a detection sensitivity which is the same as in a usual accident even when a voltage amount for compensation is lost by judging that the local terminal voltage is lost when a change in local terminal voltage is larger than a specified value and a change in remote terminal voltage is smaller than a specified value. SOLUTION: A charging current compensation amount calculating means 11 receives local terminal voltage vα and calculates charging current. A differential current. detecting means 12 receives local terminal current iα and remote terminal current iβ and calculates a differential current. Based on the differential current, a charging current compensation amount calculating means 13 calculates a differential current which has been compensated for charging current. A change in local terminal voltage vα is detected by a voltage change detecting means 14 and a change in remote terminal three-phase composite voltage vβ1 is detected by a voltage change detecting means 15.  The results are compared by an inconformity checking means 16 to find whether there is a difference between the change in the local terminal voltage and that in the remote terminal voltage and then a sensitivity of current differential characteristics is changed. By this method, an unnecessary response of a current differential relay due to a charging current compensation value loss can be prevented.

Title: Semiconductor laser element
Inventor: ONO YUICHI
IPC: H01S5/00
Filed: 1985-08-12
Abstract: PURPOSE:To perform low returning light noise by providing a waveguide region of a refractive index guide at both ends of a light emitting region, and providing a portion having the waveguide region for mainly guiding a gain at least part of the interior to generate an effect of mode filter, thereby resultantly preventing an astigmatism. CONSTITUTION:A recess 2 is formed by selective chemical etching on an N-type GaAs substrate 1. Then, an N-type GaAlAs clad layer 3, an uncoped active layer 4, a P-type GaAlAs clad layer 5 and an N-type cap layer 6 are sequentially grown. Thereafter, a P<+> type region 7 is formed by a selective Zn diffusing method to deposit an Mo-Au electrode 8 and an AuGeNi-Au electrode 9. Subsequently, it is cleaved to form a reflecting surface. A recess is also formed on the active layer above the recess 2 to produce a refractive index difference between the striped interior and the outer edge. Thus, since the laser light is enclosed in this manner, an astigmatism is small. Since no step is formed on the active layer, it becomes a normal narrow striped laser structure in multimode of laser oscillation, thereby generating no returning light noise.

Title: Liquid agent applicator
Inventor: MARUYAMA SHINICHI
IPC: A45D34/04
Filed: 1996-06-14
Abstract: PROBLEM TO BE SOLVED: To prevent the excessive emission of a liquid agent and to simplify pressure introducing operation of air by introducing built-in air into a liquid agent housing part under pressure by the pressing operation to the inside of the expanded film part provided to a cap to move a valve disc and releasing pressure to return air. SOLUTION: In the case of coating, a cap 2A is detached and the coating tip of an applicator main body 1 is turned downwardly and the valve disc 6 protruded from an outflow port 5 is pressed to a surface to be coated and pushed in against the urging of a coil spring and the liquid agent in a liquid agent housing part is allowed to flow out of the outflow port 5 to coat the surface to be coated. When the liquid agent 3 is solidified in the outflow port to be prevented from emission, the cap 2A is fitted to a coating part 11 and the expanded film part 21a of the pressure member 21 is pressed. By this method, a cylindrical part 21b penetrates into the inner deep part of an inner cylindrical part 20b and the valve disc 6 is operated so as to retreat by the air in a hermetically closed space 8.  Therefore, the outflow port 5 is opened and the liquid agent is introduced into the liquid agent housing part under pressure. When pressure is released, the pressure member 21 returns to the original position by elastic restoring force and the air penetrated into the liquid agent housing part passes through the vent holes 24, 26 becoming a communication position at a time of pressurization to return to the hermetically space 8 of the cap main body 20.

Title: Deodorant heater
Inventor: ITO FUMIHIRO
IPC: F25D21/08
Filed: 1996-07-05
Abstract: PROBLEM TO BE SOLVED: To efficiently adsorb and decompose all kinds of malodorous and odorous components including neutral odorous components and to make these components odorless by coating the surface of the effective exothermic part of a tubular heater with a catalyst layer having active carbon, the oxide of transition metal elements, zeolite, active alumina, silica and platinum metals. SOLUTION: This deodorant heater 33 has the catalyst coating layer 37 on the surface of the effective exothermic part of the tubular heater 36 provided with an electric resistance wire 35. This catalyst coating layer 37 has at least the active carbon, the oxide of the transition metal elements, the zeolite, the active alumina, silica and the platinum metals. When the deodorant heater 33 is energized, the catalyst coating layer 37 is heated in the entire circumferential direction by the heat generation of the electric resistance wire 3 and heats the deodorant heater 33 rapidly up to its activation temp. At this time, the odorous components adsorbed thus far on the catalyst coating layer 37 are released and are simultaneously oxidation decomposed by the chemical effect of the catalyst material, by which the odorous components are made odorless.  The adsorption capability of the catalyst coating layer 37 is regenerated.

Title: Apparatus and method for measurement of interval between substrates
Inventor: ONO KATSUJI
IPC: H01L21/66
Filed: 1997-07-01
Abstract: PROBLEM TO BE SOLVED: To obtain an apparatus and a method in which the interval between an upper substrate and a lower substrate can be measured surely even when the size of the upper substrate is different from that of the lower substrate by a method wherein incident light which is a beam of parallel light and whose optical intensity distribution is uniform is made incident from one side of the interval between the two substrates. SOLUTION: Incident light which is a beam of parallel light and whose optical intensity distribution is uniform is made incident, by a projection device 20, from one side of the interval 18 between two substrates 12, 14 which are bonded by keeping a very small interval by a spacer. The optical intensity of radiant light which is radiated from the other side of the interval 18 is detected by a photoreceiver 22A. The projection device 20 is connected to a moving device 30. When the moving device 30 is driven, the projection device 20 is moved to a direction (up-and-down direction) which is perpendicular to the face direction of the substrates 12, 14.  Then, the distance between the position of a light source 24 whose optical intensity detected by a light-receiving element 34 is highest and the position of the light source 24 whose optical intensity is lowest is the distance (d) of the interval 18 between the substrates. Thereby, an interval measuring circuit 32 finds the distance (d) of the interval 18 on the basis of the distance between the position of the light source 24 whose optical intensity is highest and the position of the light source 24 whose optical intensity is lowest.

Title: Reverse revolution preventing device for internal- combustion engine
Inventor: ITOU YASUO
IPC: F02D45/00
Filed: 1982-10-07
Abstract: PURPOSE:To make it possible to surely discriminate between normal and reverse revolutions of an engine, by peak-holding one polarity side of a bipolar signal generated in a signal generator and having different peak values, and by comparing the sum of the output thereof and the output of the signal generator with a reference value. CONSTITUTION:Since a signal generator 1 issues outputs having waveforms which are different in magnetic flux variation between normal and reverse rotations of a rotor 1a, the signal generator 1 issues output waveforms (a), (a'), as shown in the drawings, upon normal and reverse rotations, respectively. Therefore, the negative peak-hold outputs exhibit signals having different absolute values. Then, when the output (b) of a peak-hold circuit 2 is added to the output (a) or (a') of the signal generator 1 in an adder 3, the added output upon normal revolution shows a waveform alternately changing its polarity, but upon reverse revolution shows a waveform only having a negative polarity. Accordingly, the added output (c) is compared with a reference voltage VT in a voltage detecting circuit 4, and the output thereof is used as an ignition signal (which is not generated upon reverse direction) to energize an ignition coil 6.
