Title: Steering angle detection and computation device for four-wheel drive vehicle
Inventor: ITO MASAYOSHI
IPC: B62D101/00
Filed: 1990-11-20
Abstract: PURPOSE:To enable accurate steering angle data to be supplied to ECU by causing a vehicle to travel straight forward at the predetermined or higher speed for the predetermined time, whether neutral position information in RAM becomes incorrect or is erased, due to stopping, servicing or the like. CONSTITUTION:When an engine 2 starts and a vehicle body 1 begins to travel, learning control starts. The intervals of the learning control may be taken at every turn of a crank, or at every several turns thereof. After the start of the learning control, a travel speed VB is first calculated by TCL30. The next lowest value of wheel speeds VFL, VFR, VRF and VRR of right and left wheels at front and rear sides is used as the travel speed VB. After obtaining the travel speed VB, the TCL 30 calculates the mean value of the aforesaid four speeds or a four-wheel mean value VAV4. Then, the TCL30 makes judgment as to whether the travel speed VB is higher than the predetermined value or not.

Title: Driving circuit of ultrasonic motor
Inventor: ICHIKAWA SATOSHI
IPC: H02N2/00
Filed: 1990-11-20
Abstract: PURPOSE:To drive at least two ultrasonic motors simultaneously and, further, with an identical revolution by a driving circuit for one motor by a method wherein a plurality of the ultrasonic motors are connected to the secondary terminals of stepup transformers in parallel with each other and capacitors are connected to one of the motors in series. CONSTITUTION:Ultrasonic motors 1 and 2 are connected to the secondary terminals of two stepup transformers 124 and 125. Capacitors 101 and 102 are connected to the driving electrodes 141 and 142 of the one ultrasonic motor 2. By inserting capacitors in series with the motor, an applied voltage is divided by the ratio of an impedance obtained by the bound capacitance of the ultrasonic motor and a driving frequency and an impedance obtained by the capacities of the capacitors and the driving frequency. For instance, if the capacity of the inserted capacitor is increased from 50 nF to 200 nF, the voltage applied to the motor can be adjusted from 86% to 96%.

Title: Shredder
Inventor: MUROFUSHI KAZUTO
IPC: B02C18/06
Filed: 1995-11-30
Abstract: PROBLEM TO BE SOLVED: To certainly cut a flexible article to be cut weak in stiffness such as clothing or cloths. SOLUTION: A shredder has a shredder main body having a charging port 14 of an article to be cut, a pair of sending-in rollers 16 holding the charged article to be cut to send the same downstream and cutters 17a holding the article to be cut sent out of the sending-in rollers 16 to cut the same and is equipped with a pair of shredding rollers 17 rotated at a sending speed faster than that of the sending-in rollers 16. By this constitution, since the sending speed of the shredding rollers provided downstream is fast as compared with the sending-in rollers provided upstream in the sending direction, the article to be cut is pulled by the shredding rollers. When tension is applied to the article to be cut, even a flexible article to be cut becomes hard to deform and can be well cut between cutters.

Abstract: PURPOSE:To efficiently execute the add-on processing of the copied image of an original and a desired digital image by providing a liquid crystal shutter array where light is selectively transmitted in the optical image forming path of an image forming device which scans and exposes the original. CONSTITUTION:The liquid crystal shutter array 10 is provided on the optical path of an original image. A liquid crystal driver 25 selectively drives a specified cell to be an open/close state by synchronizing image data sent from a liquid crystal controller 24 with a horizontal synchronizing system HSYNC.

Filed: 1994-12-19
Abstract: PURPOSE: To achieve a miniaturization with a reduced number of ports and a speeding up the operation of a slide valve by switching two pipelines simultaneously with an internal cavity for communication in a slide valve body. CONSTITUTION: Two internal cavities 13a and 13b for communication are formed on a slide valve body 13 to make adjacent two ports communicate with each other among the ports B, C, D, E and F. When an air conditioning apparatus is started energizing a solenoid coil 17 of a pilot electroconductive valve 14, a valve body 16 is moved with the suction of a plunger 15 to introduce a high pressure to a pressure conversion chamber R3 so that a piston 12 or a slide valve body 13 moves in the direction of a pressure conversion chamber R2 to make the ports C and D communicate with each other by an internal cavity 13a for communication while the ports E and F are made to communicate with each other by an internal cavity 13b for communication.  Thus, with the entry of a cooling operation position, a high pressure from a port A passes through a high pressure chamber R1 to flow into the port B through the high pressure chamber R1 and the refrigerant circulates in a specified path.

Filed: 1989-12-04
Abstract: PURPOSE:To prevent the damage of reeds by forming the plate thickness of the reed, upon which fluid pressure acts largely, larger than that of the other reed between the reeds for switching each passage hole, thereby making the opening/closing timing and angles of both reeds conformable. CONSTITUTION:Reeds 5, 6 formed of elastic thin plates are disposed on the upper surface of the inclined faces 2a, 2b of a case complete 2 provided with fluid passage holes 3, 4 inside a reed valve 1 of approximately triangular cross section in such a way as to cover the passage holes 3,4. Stoppers 7, 8 for restricting opening angles are disposed on the upper surface of the reeds 5, 6. The reed valve 1 is fitted in a slightly inclined passage, so that fluid pressure acting upon the respective reeds 5, 6 differs. The thickness t1 of the reed 6, upon which the fluid pressure acts largely, is therefore set larger than the thickness t2 of the reed 5. As a result, the opening/closing timing and angles of both reeds 5, 6 can be conformable, thereby preventing the damage of the reeds 5, 6 and the generation of a spitting phenomenon.
