IPC: G01D5/36
Filed: 1979-10-08
Abstract: PURPOSE: To enable to use without trouble in a dusty surrounding by a method wherein a linear slit plate, a luminous element and a light receiving element are all contained in a case and the connection between a part to be detected and mobile part of the encoder is performed magnetically.  
     CONSTITUTION: A linear slit plate 1 and guide rods 5 are contained in a case 4. The light receiving element 6 is fitted at an end of the case 4. A set of luminous element 7 and a mirror 8 are arranged on a support member 9 horizontally movable along the slit plate 1 by means of the guide rods 5. Magnetic attraction force is made to operate between a magnetic body 11 on the lower side of the support member 9 and a magnetic body 12 on the upper side of a part 10 to be detected. In this structure, the light from the luminous element 7 passes through the transparent part of the slit plate 1, is reflected at the mirror 8 and reaches the light receiving element 6 at the end face of the case 4. Therewith, obstacle such as dust et al is eliminated out of an optical path, thus, erroneous operation is prevented.

Title: Blower-noise reducing method by phase control
Inventor: HARADA IKU
IPC: G10K11/178
Filed: 1977-10-27
Abstract: PURPOSE: To reduce the noises of more than two blowers at the same time by allowing the pressure waves to interfere each other through the phase control of the noise pressure waves of a plural number of blowers.  
     CONSTITUTION: Two runners 1 and 2 which are revolved by motors Mi and M2 are arranged on the same shaft in a casing 3. When the motor M2 is phase-shifted for the motor Mi by a fixed amount and driven, then noises interfere each other and are offset. Namely, when the distance between runners is l, and the velocity of noise is C, it takes l/C hours for the pressure wave I generated on the runner 1 to reach the position of the runner 2, therefore, in order to generate the pressure wave II which has reverse phase to the pressure wave I' after l/c hours on the runner 2, the revolution of the motor M2 is delayed by the hours At=l/C+T/2 for the motor Mi, then the phases of the pressure waves are made reverse each other on the discharge side, and noises are offset. T means a period.

Title: Speed change control method for automatic speed change gear for car
Inventor: YASUE HIDEKI
IPC: B60W10/18
Filed: 1984-06-22
Abstract: PURPOSE:To prevent abrasion of a brake pad by conducting down-shift operation at a car velocity which will produce no speed change shock sensed by a driver's body during meandering, and conducting down-shift operation at a designated car velocity in such a manner that the rotational frequency of a torque converter becomes equal to the idling rev count during braking in an automatic speed change gear for a car. CONSTITUTION:In an automatic speed change gear 1 having an engine 100 and a fluid torque converter 3, during meandering, down-shift is conducted at a car velocity which will produce no large speed change shock sensed by a driver's body according to a basic speed change pattern. During braking, down-shift is conducted at a designated car velocity in such a manner that at each speed change step, the rotational frequency of a turbine of the fluid torque converter 3 becomes equal to the idling rev count of the engine 100. Thus, a brake pad of a brake for braking a car is avoided from being worn away in its early stage by driving force.

Title: Judging method for cleaning accuracy of adsorbed material on wall face
Inventor: SAKAMOTO OSAMU
IPC: G01N1/00
Filed: 1993-05-31
Abstract: PURPOSE:To provide a cleaning accuracy judging method which is simple in operation and safe and economical in cleaning accuracy, and moreover based on the measurement of the residual quantities of substances being adsorbed or adhered, especially species of aminos as a bad-smelling material on a storage wall face after cleaning. CONSTITUTION:The pH of a fixed quantity of distilled water is previously measured. Material being adsorbed within the fixed area of a storage wall face after cleaning is wiped out, and the wiped adsorbed material is dissolved in the fixed quantity of distilled water, and the pH of the distilled water where the adsorbed material is dissolved is measured, and compared with the previously measured pH value of the distilled water. When both the measured values are mutually approximate, it is judged that the storage wall face after cleaning has no adsorbed bad smelling material, and is excellent in cleaning accuracy. When a difference between both the above pH measured values is large, since the bad smelling material remains on the storage wall face after cleaning, its cleaning accuracy is judged to be bad, and the cleaning of the wall face is repeated.

Title: Method for checking presence of module of optical multiplex transmitter
Inventor: YOSHIMOTO YUKIO
IPC: H04B10/00
Filed: 1983-07-15
Abstract: PURPOSE:To prevent the transmission of an erroneous signal by bringing the level of a specific edge connector of an input/output module of an optical multiplex transmitter into logical H and detecting the potential of a specific bus on a mother board on the other hand so as to detect the presence of the module on the mother board. CONSTITUTION:When a certain module 2 is assembled to a connector T1, i.e., the mother board 5, the level of a terminal t1 of the connector T1, i.e., the bus A obtains logical H. If the module is not assembled conversely, the level of the terminal t1 of the connector T1, i.e., the bus A obtains logical L. Further, a control module is fitted to the edge connector the same as other modules, the voltage of the bus A is checked in this state and only when the voltage exists, each input/output module is made possible for the operation. Thus, if the input/output module is not assembled to the mother board, the transmission is prevented by reading the state of the bus.

Title: Amplifying circuit
Inventor: KAMIMURA TAKUZOU
IPC: H03F1/00
Filed: 1981-08-18
Abstract: PURPOSE:To prevent generation of a transient output in case when an electric power supply is turned on, by maintaining a bootstrap circuit of an amplifying circuit in a nonoperating state, and also precharging a capacitor of a feedback circuit, when the electric power supply is turned on. CONSTITUTION:When an electric power supply 6 is turned on, in a constant interval of time within a time when a potential difference is generated in a resistance 36, a transistor TR50 becomes an on-state,and a capacitor 30 is charged by a detecting output supplied from an emitter and collector C1, that is to say, a charging current. On the other hand, while the TR50 is in an on-state, TR58 is in an on-state and TR60 is in an off-state, therefore, TR56 becomes an off- state, and a bootstrap circuit is maintained in a nonoperating state. These operating states continue until the charging potential of a capacitor 38 is shifted to supply voltage Vcc, and during this time, generation of a transient sound in a muting time can be prevented effectively.

Title: Copybook to enable perceptive learning of character and its pen
Inventor: HATANAKA NAOYUKI
IPC: G09B11/04
Filed: 1993-04-21
Abstract: PURPOSE: To eliminate the need for writing image lines by storing the modulation and stroke directions of a copy and to enable efficient learning as the learning of the copybook itself is possible. CONSTITUTION: A learner holds a pen 1 by an arm resting method or arm suspending method and traces the grooves 9 of the copybook 8 with the pen. In such a case, the projecting part of the bearing at the pen tip and the recessed parts of the grooves 9 are of the same diameter and, therefore, a 'deviation' is prevented. The hand and the fingers are moved smoothly according to the grooves 9 in the stroke direction by the effect of the bearing. The learner is able to perceptively learn the movements. Namely, the learner with the pen 1 in his hand traces many times the grooves 9 of the copybook 8 with the pen 1 and confirms the writing by writing the character on white paper after perceptively storing the character. The learner repeats tracing by repetition of such operation until the learner learns the character. Since the copybook is traced many times by the pen 1 in such a manner, rhythms of the character are easily obtd. and the effective learning is attained.
