Title: Neutral steering angle estimating device
Inventor: SHIRAISHI YASUHIRO
IPC: B62D7/14
Filed: 1989-05-15
Abstract: PURPOSE:To rapidly return a neutral angle estimating value to a regular value by a method wherein it is detected whether the neutral steering angle estimating value of a handle has an error, and when it has the error, the computing condition of the neutral steering angle estimating value is initialized. CONSTITUTION:The steering angle of a handle is detected by a means (a) and the neutral position of the handle is detected in a given range by a means (b). When, in the neutral position of the handle, a given computing condition containing a correction steering angle condition and a running distance condition is satisfied, the estimating value of a neutral steering angle is computed by a means (c). It is detected by a means (d) whether the estimating value of the neutral steering angle has an error. When the estimating value of the neutral steering angle has no error, the computing condition is made sever so that the computing condition is updated from a non-sever initial state. Meanwhile, when it has an error, the computing condition is set by a means (e) so that the computing condition is initialized.

Title: Computer system and method for operating of bus interface device
Inventor: JIERAADO TEI MATSUKII
IPC: G06F13/36
Filed: 1995-05-19
Abstract: PURPOSE: To provide an integrated processor which uses an improved address decode method between bus cycles of an external master. CONSTITUTION: An external PCI master can start a cycle (either memory or input-output) on a PCI bus 518 by asserting an address signal to the PCI bus 518. A bus interface unit 510 transfers the address signal to a CPU local bus 508. A decode logic in memory or input-output controllers 504 and 506 decodes the address signal and decides whether the address is mapped in an address space of each of the controllers 504 and 506. If the address exists in a mapped space of each of the controllers 504 and 506, the controllers 504 and 506 assert a hit signal and notifies the unit 510 that the address is mapped to a device positioned on the bus 508.

Title: Operation system of vacuum circuit breaker
Inventor: IKEDA JUNICHI
IPC: H01H9/56
Filed: 1990-05-14
Abstract: PURPOSE:To make a vacuum circuit breaker small and light by carrying out contacting and parting operation of a plurality of vacuum circuit breakers driven through an axial circuit on one main shaft in the time order of each circuit breaker. CONSTITUTION:A vacuum circuit breaker is composed of a plurality of vacuum valves in, for example (a) phase, (b) phase, and (c) phase, and having a fixed contact 2 and a movable contact 3. The movable contact 3 comes into on and off states owing to reciprocal movement of an insulating rod 10A having a wipe spring 9. The insulating rod 10A moves reciprocally by a crank movement owing to the rotation of one main shaft 12 through a lever 11 installed in the main shaft 12. The length La, Lb, and Lc of each insulating rod are made longer in this order. The narrow angles alphaa, alphab, alphac between each lever and each insulating rod are made narrower in this order. Consequently, touching and parting the contacts 2, 3 are carried out successively in each vacuum valve and thus a load force for touching and parting becomes low and the circuit breaker is made small.

Title: Wire dot printer
Inventor: HAYASHI MIKIO
IPC: G06K15/10
Filed: 1979-09-20
Abstract: PURPOSE:To reduce current consumption, impact noise, and so on and prevent  initial dot drop-out, by adding a print lever fine moving circuit and by moving  finely all print levers before the print operation to weaken previously adhesion between print levers and other parts. CONSTITUTION:When print lever fine movement command signal Pc is generated,  the Q' signal of the flip flop, namely, control signal Pf is inverted from ''1'' to ''0''.  Then, the output of each tri-state buffer BUFi becomes ''1'' and the gate of each  AND gate 22AGi is opened. When print lever fine movement command signal Pc  falls, output signal Pd is generated from one shot pulse generator 16 and is supplied  to each AND gate 22AGi. Consequently each print levr driving circuit DRi is  operated to apply a minute driving current to each driving coil SOLi. Each print  lever slides clockwise slightly, and adhesion between arm 1a and stopper 12 and between arm 16 and yoke 11 is weakened.

Title: Wrapping unit for photosensitive material provided with exposure function
Inventor: SHIBA KEISUKE
IPC: G03C1/76
Filed: 1988-05-18
Abstract: PURPOSE:To make it possible to impart the exposure function to the title unit which is portable, light in weight and small in size and is capable of simply taking a photograph by composing a supporting body of a specified polyester film. CONSTITUTION:The photosensitive material in which a photographic sensitive layer is mounted on a transparent supporting body, and a back layer is mounted on the opposite side of the supporting body against the photosensitive layer, is involved in the wrapping unit. And, the supporting body is composed of a polyester film which has a moisture content of >=0.5wt.% and a breaking strength of 8-25kg/mm<2>, and an initial elastic modulus of 200-600kg/mm<2>. Namely, in order to make a wrapping unit body to small in size, the winding radius of the photosensitive material is reduced in size. But, the winding habit of the photosensitive material before and after development processings is entirely dissolved by using the supporting body as mentioned above. Thus, the unit is portable, light in weight and small in size and also makes it possible to take simply photography. The exposure function capable of being obtained a photography with high image quality is imparted to the unit by returning the unit as it is, to a DP.
