Patent JP-S6050231-A (JP)
Title: V-type two-cylinder engine
Inventor: ARAI NAOTAKE
IPC: F02B61/02
Filed: 1983-08-29
Abstract: PURPOSE:To shorten a wheel base and improve cooling performance by substantially vertically arranging the crank shaft of a V type two-cylinder engine and locating two V type cylinders at particular positions. CONSTITUTION:The crank shaft 21 of a V type two-cylinder engine 20 is substaintially vertically arranged. Two sets of cylinders 22, 23 and cylinder heads 24, 25 are perpendicular to the crank shaft 21, projected in front of a car body, and divided to the right and left symmetrically with respect to a center A-A extending longitudinally to the car body. A down tube 19 vertically extends between both side cylinders 22, 23. Hereby, the down tube 19 enters the inside of a V bank of the engine 20, enabling the wheel base to be shortened. In addition, it is possible to improve cooling performance since cooling wind sufficiently hits the whole of the engine.

Title: Light monitor apparatus
Inventor: NISHIDA KATSUHIKO
IPC: H04B10/079
Filed: 1977-12-27
Abstract: PURPOSE: To reduce insertion loss and correctly monitor the change of light signals by reflecting the light emitting from a light introducing optical system on a light detector surface then detecting the absorption light accompanied when this light is reflected.  
     CONSTITUTION: Light emitted from a light transmission path 1 being a light introducing optical system reflects on the surface of a semiconductor photo diode 3 and enters an optical transmission path 2 being a light leading-out optical system. Since the refractive index of the semiconductor is high, the optical transmission paths assume an angle close to perpendicular to the surface of the photo diode 3, thus photoelectric conversion may be effectively accomplished by the photo diode and an electrical output is produced in electrodes 4, 5. If a Schottky barrier type is used for the photo diode, the reflection may be efficiently accomplished by the Schottky metal 6. Thereby, light signals may be faithfully monitored with the small and simple construction.

Title: Link channel establishing system
Inventor: KATO KENICHI
IPC: H04W72/04
Filed: 1995-06-26
Abstract: PURPOSE: To allow the operator to recognize the presence of an idle slot and idle channel by means of an alarm tone or the like when an idle slot and an idle channel are produced by reporting periodically the presence of the idle slot and the idle channel from a radio base station. CONSTITUTION: A radio terminal equipment 9 is made up of a radio section 7 making communication with a radio base station 8, a display section 1 to provide information to the operator, an alarm tone generating section 2, an operation section 3, a voice processing section 4 processing transmission reception speech, and a control section 5 controlling the sections above. When the radio terminal equipment 9 makes a call to conduct communication, the terminal equipment 9 requests setup of a link channel to the radio base station 8. When no idle channel and no idle slot is available, it is reported and the radio terminal equipment 9 is in standby supervisory state. The radio base station 8 sends an information notice signal and information of idle slot and idle channel is added to the signal. The radio terminal equipment 9 uses the monitor section 6 to monitor the presence of the idle slot and idle channel and when the idle slot and idle channel exist through the reception of information, it is displayed or reported to the operate by an alarm tone.

Title: Liquid feeder
Inventor: MATSUURA TAMIZO
IPC: G01N1/14
Filed: 1988-06-27
Abstract: PURPOSE:To enable pulsation-free feeding of a liquid with a simple construction by discharging a liquid from both specified angle-of-rotation sections through a cam in a constant flow liquid feeder using a pump and damper always to keep a total discharge level constant. CONSTITUTION:Cams 13 and 23 of a pump 10 and a damper 20 are turned with a motor 30 to reciprocate plungers 11 and 21 and a liquid of a tank 1 is discharged once sucked with the pump 10 to be fed while a part thereof is being sucked into a damper 20. During the discharging with the pump 10, the liquid is discharged with the damper 20. In this manner, a continuous feeding of a liquid is performed. The profile of the cams 13 and 23 is such that both the pump 10 and the damper 20 are ready for discharging in a fixed angle-of- rotation section. This permits always keeping of a total discharge flow of the pump and damper constant thereby accomplishing a pulsation-free feeding of liquid with a simple construction.

Title: Riding simulator for two-wheeler
Inventor: AOKI KATSUTO
IPC: A63F13/245
Filed: 1990-06-18
Abstract: PURPOSE:To obtain an acceleration/deceleration feeling similar to that by an actual two-wheeler by varying the pitch angle of a vehicle body according to the acceleration or deceleration of a two-wheeler. CONSTITUTION:The pitch angle of the vehicle body is varied according to the acceleration or deceleration of the madel two-wheeler and an image displayed on a display device is altered, kpreferably, with the pitch angle of the vehicle body. Namely, the pitch angle is varied so that the vehcle body is slanted backward in the acceleration staste of the model two-wheeler and slanted forward in the deceleration state; and the view point of the rider moves up and down owing to pitch motion in the acceleration or deceleration state, so the display image is shifted upward above a constant-speed travel position when the view point moves up owing to the acceleration and shifted down when the view point moves down owing to the deceleration. Consequently, the rider can feels acceleration or deceleration without any feeling of physical disorder.

Title: Pressure sensor
Inventor: ISHIBASHI KIYOSHI
IPC: G01L9/04
Filed: 1980-11-10
Abstract: PURPOSE: To prevent thermal stress strain due to the adhesion of different kind of materials from extending to a diaphragm by bringing a pressure sensor chip into contact with the internal surface of the bottom board of a holding box which limits the movement of the chip, and by adhering the external surface of the bottom board to a package.  
     CONSTITUTION: A holding box 70 is soldered to the metallic frame 31 of a stem 31, but a pressure sensor chip 10 is mounted on the internal surface of the bottom board 71 of the holding box only in contact without being adhered, so that it is slidable. Consequently, thermal stress strain due to a difference in thermal expansivity between materials of the metallic frame 31 and holding box 70 never extend to the pressure sensor chip 10. Therefore, a diaphragm 11 is never influenced by the thermal stress strain.

IPC: B62D7/14
Filed: 1989-06-20
Abstract: PURPOSE:To avoid the full steer state at the time of trouble so as to improve safety by providing a means for oil-locking bilateral hydraulic cylinders interlockingly with the abnormality detection of a control system. CONSTITUTION:When the oil pressure or supply voltage of a control system is lowered abnormally, ducts 53-55 are closed to place bilateral hydraulic cylinders 33 in the oil lock state. Also, when a driver senses abnoramality, the hydraulic cylinders 33 can be placed in the oil lock state optionally by a switch 76. Rear wheels are thereby prevented from being placed in the full steer state when trouble is generated, thus heightening safety.

Filed: 1990-06-18
Abstract: PURPOSE:To decrease the tightening force of coating layers to be impressed on an optical fiber and to improve an optical transmission loss characteristic by setting the coefft. of linear expansion of the inside and outside coating layers within a specific range in the formation of the coated optical fiber by thin coatings to a smaller diameter. CONSTITUTION:The ultra-thin coated fiber has <=0.16 mm outside diameter of the coating and concentrically has a buffer layer B2 on the inner side and a coating layer C3 on the outer side. The Young's modulus ratio EC/EB of the coating layer C3 and the buffr layer B2 is >=1000 and the coeffts. of linear expansion of the coating layer C3 and the buffer layer B2 are so satisfied as to satisfy equations I to equation III. In the equations I to III, K1 denotes the temp. change ratio of the buffer layer and the coating layer and is 1<K1<2; KB is the thickness of the buffer layer and denotes a mum unit. Since the force applied on the optical fiber surface is substantially decreased in this way, the increase in the loss generated by microbending is drastically decreased and is stabilized.
