Title: Optical pressure transducer
Inventor: KURISUTOFUAA PII GURAJIIN JIYU
IPC: G01L9/00
Filed: 1993-06-29
Abstract: PURPOSE: To enable an optical pressure transducer to operate in a severe working environment by detecting changes in the amount of light using a reflector linked with a force-responsive diaphragm which takes a deflected position when detecting pressure at a different level. CONSTITUTION: Light emitted from an input optical fiber 3 is masked by an input opening 8, is varied in its light intensity pattern, and is reflected by a freely moving reflector 10 coupled to a concentrating diaphragm 2. An optical path 25 corrected is reflected from the freely moving reflector 10 toward a fixed reflector 11 and enters an output optical fiber 4 via an output opening 9. An initial amount blocked from the end of the output optical fiber 4 is determined by the initial vertical position of the freely moving reflector 10. If pressure is applied to the surface of the diaphragm 2. the freely moving reflector 10 is displaced in the vertical direction, so that the proportional amount of the corrected intensity pattern incident on the receiving end of the output optical fiber 4 is changed.  This change is detected at time output end of the output optical fiber 4 by a photodetector such as a photodiode 4A.

Title: Connection control system of time division multi-switch
Inventor: ITOU KIICHIROU
IPC: H04Q11/04
Filed: 1980-12-23
Abstract: PURPOSE:To avoid multi-connection and erroneous disconnection caused by a holding memory erroneously written by erroneous operation of upper control system, by installing space indication memory corresponding to ON/OFF high-way of time division multi-switch. CONSTITUTION:For example, when l1m1 are connected by channel t0, simultaneously when l1 is written on the lot number of t0 of the holding memory HMm1, ''1'' (space display) is set on the lot of t0 of the space display memory BMm1 and BM11. Under this condition, if a command to connect l1 to m2 in channel t0 is input, the control device BMCTL reads out the lot number t0 of the space display memory BM11 and BMm2. In this case, as the lot number t0 of the memory BM11 is ''1'' (space display), pass connection from the control device BMCTL to the control device HMCTL is prohibited.

Title: Internal combustion engine having two pistons
Inventor: ASAKURA HIROYUKI
IPC: F02B75/28
Filed: 1994-06-30
Abstract: PURPOSE:To improve energy conversion efficiency and to reduce the occurrence of vibration by a method wherein two pistons are arranged at positions, situated facing each other, in a combustion chamber in a semicircular cylinder and the two pistons are coupled to a central shaft through an arm formed integrally with the pistons. CONSTITUTION:When explosion occurs in the combustion chamber 2 of a cylinder 1, pistons 3 and 4 intercoupled through arms 5 and 6 integrally formed on a central shaft 14 effect lowering movement on a concentric circle. Arms 7 and 8 coupled to the arms 5 and 6 are intercoupled at a fulcrum 15 and the fulcrum 15 is lowered on a straight line through lowering movement of the two pistons. A connecting rod 9 coupled to the fulcrum 15 is coupled on a crank shaft 10 and perform half rotation around the crank shaft. In such a way that, in this structure, four cylinders are arranged as a four-cycle internal combustion engine, the crank shaft is continuously rotated. As a result, by increasing conversion from combustion energy to movement energy, fuel is saved and the generation of vibration is reduced.

Title: Hydraulic circuit provided with line filter
Inventor: UEDA KOUJI
IPC: F15B21/04
Filed: 1981-11-14
Abstract: PURPOSE: To ensure the countermeasure to oil contamination by controlling the discharge volume of a hydraulic pump by a specific controlling means so that the differential pressure between the inside and the outside of a filter element is lower than a predetermined value.  
     CONSTITUTION: A rod 11 of a double rod cylinder 10 is opposed to a lever 9 attached to the middle of a rod 8 for controlling an engine 7 driving a hydraulic pump 16. Both chambers of the cylinder 10 are respectively communicated with the inlet port 14a and the outlet port 14b of a line filter 14 incorporating therein a filter element 14c. A spring 15 disposed in the chamber near the lever 9, of the cylinder 10 pushes the lever 9 through the rod 11 when the differential pressure across the filter element 14c reaches a predetermined value, for controlling the speed of the engine 7 to a minimum number of revolutions. Thereby the pump 16 connected to the inlet port 14a may be controlled by the differential pressure between the inlet and outlet ports 14a, 14b through the engine 7, resulting in that a relief valve may be eliminated, and all oil may be passed always through the filter element 14c.

Abstract: PURPOSE:To obtain a mechanical device of simple structure which does not require a reciprocal winding mechanism by extending an endless cylindrical shutter film between a couple of rotary support bodies and positioning a solid- state image pickup element inside, and forming a shutter aperture and rotating it. CONSTITUTION:When the endless shutter film 21 rotates and the shutter aperture 26 passes by the solid-state image pickup element 25 continuously, the passing of the shutter aperture 26 by the solid-state image pickup element 25 is detected and its detection signal is inputted to a phase difference detecting circuit 32. The phase difference detecting circuit 32 controls a motor 24 so as to correct the phase difference between the detection signal and a vertical synchronizing signal from a synchronizing signal generating circuit 30. The vertical synchronizing signal and a horizontal synchronizing signal are supplied to the solid-state image pickup element 25, which is driven synchronously every time the shutter aperture 26 passes. Consequently, a light signal of a subject is stored in the solid-state image pickup element 25 only for a short period when the shutter aperture 26 passes and then read out through a video signal amplifying circuit 33.

Title: Brake control device
Inventor: SHIBATA TAICHI
IPC: B60T8/24
Filed: 1999-06-29
Abstract: PROBLEM TO BE SOLVED: To enhance the quality of control by enhancing the accuracy of determining an oversteered condition. SOLUTION: This brake control device includes a control means (d) which performs oversteer control to actuate a hydraulic pressure controlling actuator (b) to generate braking forces at desired wheels to restrain yaw moments produced in the vehicle to thereby stabilize vehicle behavior when the vehicle behavior is determined to be in an oversteered condition according to an input from a vehicle behavior detecting means (c). The control means (d) performs gain determination such that determination on the oversteered condition is made based on a value obtained when the difference between a desired yaw rate produced from both steering angle and vehicle body speed and the yaw rate detected by a yaw rate sensor is multiplied by a gain. Thus, the accuracy of control at low speeds can be made higher than in devices of the prior art.

Title: Magnetic head

IPC: G11B5/23
Filed: 1994-07-12
Abstract: PURPOSE:To make it possible to make up deterioration of the spacing loss by formation of a protective film of a magnetic head formed with the protective film on its recording medium-sliding surface. CONSTITUTION:The deterioration of output by the spacing loss arising from the thickness of the protective film is generated when the protective film is formed on the sliding surface of the magnetic head. The magnetic gap loss is lowered and further, the reproduction efficiency is improved by setting the length G1 and depth Gd of a magnetic gap shorter than reference values (for example, G1=1.5mum, Gd=0.2mum) in order to make up the deterioration. Consequently, the reproduction sensitivity is enhanced to make up the spacing loss. The length G1 and depth Gd of the magnetic gap are set at the combinations shown in diagrams, by which the spacing loss with respect to the respective film thicknesses is completely made up. The spacing loss is made up to some extent by setting the G1 and Gd smaller than the reference values.
