Title: Call progress tone discrimination method for telephone exchange
Inventor: ARIGA HIROSHI
IPC: H04M3/36
Filed: 1991-05-29
Abstract: PURPOSE:To reduce the load of a control section in the case of discriminating a call progress tone to recognize the operating state of a line. CONSTITUTION:A control section 7 uses a characteristic calculation section 71 to detect a call progress tone from a line I/F 5n thereby calculation an ON time, a period, and an ON time rate, which are sent to a fuzzy deduction section 72. The fuzzy deduction section 72 receives the ON time, the period, and the ON time rate to implement fuzzy deduction and to discriminate whether the call progress tone is a ring back tone or a busy tone. Since the discrimination speed is improved, the control section has less monitor time thereby relieving the load of the control section.

Title: Method and equipment for interference positioning
Inventor: KAWASHIMA SHIGEO
IPC: G01S5/02
Filed: 1996-04-24
Abstract: PROBLEM TO BE SOLVED: To enable easy determination of an integral value of a carrier frequency by a method in which a distance between a receiving antenna of a fixed receiver and a receiving antenna of a movable receiver is set to be a half wavelength of the carrier frequency or less. SOLUTION: A distance (m) between a receiving antenna 20 of a fixed receiver 2 fixed at a reference point A and a receiving antenna 30 of a movable receiver 3 at an adjacent point B is set to be m<(1/2).λ when one wavelength of a carrier frequency from a GPS satellite 1 is made λ. When an optical-path difference between the fixed receiver 2 and the movable receiver 3 is within a 1/2 wavelength, in other words, a wavelength difference (difference in the number of wavelengths) made integral can be determined automatically as 0, that is, integer ambiguity can be determined as 0. In this way, the integer ambiguity can be determined very easily and it is possible to improve operability sharply and to lessen the possibility of causing false measurement. Therefore relative positioning in centimeters can be executed even by general users.

In this case, a limit piston 20 which prohibits the shift over a certain value of the control piston 3 is installed. Then, the limit piston 20 is operated by receiving the transmitted hydraulic pressure to the control oil chamber D as back pressure.

Title: Electrothermal transfer recorder
Inventor: FURUKAWA MASANOBU
IPC: B41J2/325
Filed: 1987-05-22
Abstract: PURPOSE:To automatically maintain a pressing force per unit area at a substantially constant value and maintain stable printed image quality, by providing a counting means for counting the moving distance of a recording head, and a head-pressing means which sequentially increases a head-pressing force when a preset count is reached. CONSTITUTION:When a count obtained by a controller reaches a preset value, the number of steps of a head-pressing motor 3 is increased by a preset value, and an output shaft 3a of the motor 3 is rotated counterclockwise by a predetermined angle. As a result, deformation of a leaf spring 6 is increased, resulting in an increase in the force with which the tip of a recording head 2 is pressed against a recording film 9. A setting is previously made so that the increase in the pressing force corresponds to the wear of the head 2 due to feeding, whereby the pressing force per unit area is maintained at a substantially constant value.

Title: Solenoid valve
Inventor: OSONE TATSUYA
IPC: F16K31/06
Filed: 1995-05-25
Abstract: PURPOSE: To prevent contamination in control fluid from invading clearances of the sliding part of a movable iron core and the collision part by shutting the space between clearances which exist between the movable part outer peripheral surface including at least movable iron core and a valve body and the fixed part inner peripheral surface positioned on the outer periphery of the movable part in opening of the valve, and a fluid passage. CONSTITUTION: Since a seal ring 14 is brought in contact with a seat surface 15 of a guide member 9, blocks and seals a clearance when a fluid passage 1C is released and fluid is made to pass through the fluid passage 1C after a valve 7 is separated from a valve seat 5 in opening of a valve, control fluid which has reached to the fluid passage 1C can be prevented from invading the clearance 12 of a sliding part of a plunger 6 and a clearance 13 of a collision part of the plunger 6 to a locking part 11. Therefore, the possibility that contamination in control fluid invades the clearances 12, 13 of the sliding part and the collision part of the plunger 6 is eliminated, and generation of break and stick of the plunger 6 and the guide member 4 can be prevented.

Filed: 1990-05-18
Abstract: PURPOSE:To perform measurement even in the case of mixture of toner particles different in polarity by applying an alternating electric field between a developer carrier and a counter electrode to separate an electrified developer from the developer carrier. CONSTITUTION:An alternating electric field is applied between a developer carrier 2 and a counter electrode 3, and toner particles electrified with positive and negative polarities by this alternating electric field are flied to the counter electrode and are taken into a measuring system by an air current 5 generated around the electrode. A laser generator 23 and a laser light reception device 24 are arranged, and the phase delay of electrified toner particles 4 to air oscillation and the deviation speed due to the electric field are measured by the laser Doppler method to obtain the particle size and the extent of electrification of electrified toner particles 4 by operation in an arithmetic part 12. Thus, toner particles 4 can be separated and gathered independently of their electrification characteristic, and measurement is possible even in the case of mixture of toner particles different in polarity.

Title: High visibility luminous body for road
Inventor: KURODA MAKOTO
IPC: E01F9/524
Filed: 1999-05-07
Abstract: PROBLEM TO BE SOLVED: To enhance the visibility of a driver in nighttime and rainy weather by embedding a light-emitting electronic emission body and a light-reflection body irregularly reflecting irradiated light by being energizing in a transparent or translucent rectangular body, and burying the rectangular body in a state where the upper face is exposed on a road surface to constitute a road surface line.

Title: Stencil mask for electron beam exposure
Inventor: NIIJIMA TAKAYUKI
IPC: G03F1/20
Filed: 1999-05-07
Abstract: PROBLEM TO BE SOLVED: To settle occurrence of thermal distortion under heat for suppressed failure in a mask pattern by bonding/fitting a stencil mask main body for electron beam exposure to a conductive supporter surface by one point. SOLUTION: The lower surface along one side of a stencil mask main body 10 is bonded/fitted to the upper surface of recessed part of a metal holder 15 by one point. The position for bonding/fitting with an adhesive 16 does not extend to the entire perimeter of the stencil mask main body 10 but limited to any one point. There is a large difference in linear expansion factor between the stencil mask main body 10 and the metal holder 15. No compression stress due to thermal distortion is applied on the mask main body 10 even if bonding with the adhesive 16 is processed through high-temperature heating or cooling to a room temperature, since the part other than the bonding point is free. The less the area of the region of that one point for bonding, the batter the bonding effect.  If the area has a diameter four times of the thickness of the mask main body 10 or less, no effect of thermal distortion occurring in the bonding region is presented.

Title: Self-oscillating semiconductor laser
Inventor: OYA MASATERU
IPC: H01S5/227
Filed: 1999-05-07
Abstract: PROBLEM TO BE SOLVED: To provide a self-oscillating semiconductor laser which can maintain self-oscillating operations to a high temperature. SOLUTION: In a self-oscillating semiconductor laser, a carrier absorbing layer 106 is provided between an active layer 104 and a saturable absorption layer 108. In general, the overflow of carriers from the active layer 104 to clad layers increases as the temperature rises. However, the overflowing carriers are recoupled and become extinct in the carrier absorbing layer 106, and no excessive carrier is injected into the absorption layer 108. Therefore, the laser can make stable self-oscillating operations, because the operations do not stop even at a high temperature.
