Title: Signal transmission circuit using photocoupler
Inventor: HASHINAGA HITOSHI
IPC: H03H11/02
Filed: 1987-12-17
Abstract: PURPOSE:To obtain an output signal with a large S/N by increasing the stimulated quantity of a light emitting diode and extracting an output signal of a photodetection transistor(TR) at the same level as an input signal via a voltage division resistor. CONSTITUTION:A variable resistor 17, in the input of a signal voltage to a TR 7, regulates a current IIN flowing to a light emitting diode 9 to set the operating level of the photodetection TR 10 as large as possible to the extent that the TR is not saturated. Thus, an output voltage appearing at the emitter of the photodetection TR 10 is increased. Voltage division resistors 18, 19 divide the output voltage and the output voltage with the same amplitude as a signal voltage outputted from a signal voltage source 2 is outputted at an output terminal 20. Thus, the noise caused in the photodetection TR 10 is reduced by a resistance ratio of the voltage division resistors 18, 19, an output signal with a large S/N is obtained.

IPC: B60R13/02
Filed: 1998-11-12
Abstract: PROBLEM TO BE SOLVED: To easily and quickly attach not only interior trim materials but also various exterior materials at a concurrent progress by attaching a body side model to a travel means for separating from each model by a prescribed distance. SOLUTION: At the time of using an inspection jig 101, both body side models E and E integrated via a roof model D are first moved to the rear side of a block 1. As a result, a hindrance to disturb a work to fit interior trim materials is eliminated from the surrounding area of each floor, front and rear models A to C. On the other hand, the models A to C for disturbing each interior trim material is not present inside both of the body side and roof side models E and D. Thus, fitting works for interior trim materials to a dummy body is shared by a group in charge of the models A to C of floor, dashboard and an upper back, and another group in charge of the models D and E of body side and roof, thereby developing a work concurrently.

Title: Route guidance apparatus for vehicle
Inventor: NAKAYAMA OKIHIKO
IPC: G01C21/00
Filed: 1993-12-21
Abstract: PURPOSE:To shorten the search time of an optimum route when a vehicle is deviated from the route by searching the optimum route from a destination up to every crossing in its periphery continuously. CONSTITUTION:The route guidance apparatus for a vehicle is provided with a direction sensor 1, a vehicle-velocity sensor 2, a map storage memory 3, a CPU 4, a ROM 5, a RAM 6, a V-RAM 8 and a display 9. The CPU 4 first operates an optimum route up to a destination from a present point, and the vehicle is guided according to the route. When the vehicle starts to run, the CPU 4 operates an optimum route from the destination by utilizing an empty time. In addition, the CPU 4 periodically detects whether the vehicle has been deviated from the optimum route. When it has been deviated from the route, a new route is not searched as long as a route up to a present point has already been searched. On the other hand, when the route up to the present point is not searched, a range in which the route has already been searched is utilized to the full, and the route is searched. As a result, the search time of the route is shortened when the route is deviated from the optimum route.

Title: Travel controller for motor driven vehicle
Inventor: MARUTANI YOSUKE
IPC: B60L3/00
Filed: 1987-12-22
Abstract: PURPOSE:To obtain a suitable braking force at the time of controlling plugging by outputting a command having a predetermined conduction rate when the command of a conduction instruction unit decreases lower than the predetermined conduction ratio, and reducing an acceleration command when the conduction ratio command decreases lower than a predetermined value. CONSTITUTION:A conduction ratio instruction unit 5 compares an acceleration command signal from an acceleration instruction unit 3 with a motor current from a motor current detector 7, and it outputs a conduction ratio command. A command selector 17 selects a larger one of a conduction ratio command and a predetermined conduction ratio from a predetermined conduction ratio instruction unit 13, and outputs it to a chopper 9. On the other hand, a conduction ratio comparator 21 reduces the signal from the unit 3 when the output of the selector 17 decreases lower than a predetermined value. Thus, the vibration of an automotive body can be suppressed at the time of controlling plugging.

Title: Generating plant and method and device for controlling water level
Inventor: NONAKA SETSUO
IPC: F01K7/24
Filed: 1990-11-28
Abstract: PURPOSE:To prevent abnormal-fall of water level after flashing in a vessel for storage of saturated water or compressed water by a method wherein specific gravity of drain in the vessel is measured and if said measured value indicates occurrence of flashing of drain, delivery quantity of drain is increased or feed quantity is decreased and if said value indicates decrease of flashing, delivery quantity is decreased or feed quantity is increased. CONSTITUTION:When average specific gravity of drain in a drain pipe between detecting means 62, 63 has become lower than normal specific value in a flash-free state, the opening of a control valve 5 for normal use is opened in advance to nut the water level within a specified range, judging that flashing may take place in a drain tank 2 and drain in a drain pipe 61 may flow backward into the tank 2 and hence the water level therein may rise. When said specific gravity has become higher than normal value, the opening of the valve 5 is made smaller to keep the water level within a specified range, judging that flashing in the tank 2 may be crushed and the drain in the tank 2 may abruptly flow into the pipe 61 and hence the level in the tank 2 may fall down. Consequently, fluctuation of water level in the drain tank due to flashing can be restrained and said level can be stabilized.
