Filed: 1988-05-31
Abstract: PURPOSE:To perform an emergency corresponding operation and to eliminate user's inconvenience by providing backup control means for operating by ignoring a device of a refrigerating cycle and components of the device when the device or the component is defective. CONSTITUTION:A controller 20 sequentially detects whether a pressure sensor 6 is defective or not by trouble detecting means 20a, and stops all operations when it detects a trouble. Simultaneously, the lamp 22a of an indicator 22 is lit. When a user who confirms the lighting of the lamp 22a closes the backup set switch 21a of an operation section 21, the controller 20 executes a backup control, performs an operation by ignoring the sensor 6, and flashes the lamp 22a. In this operation, a maximum operating frequency Fmax is suppressed to a low value so that a high pressure side pressure does not become excessive in a general using state. The set values of ON/OFF operation control by the detected temperatures Ta, Tb of temperature sensors 7, 8 are reduced to be severely operated.

Filed: 1984-06-29
Abstract: PURPOSE:To shift virtually an electrode of an inter-block bit and to eliminate the blur between blocks by driving a block with a part of the preceding and next data put on another block in case said one block is driven by multiple styluses. CONSTITUTION:64 circuits are formed to high voltage drive circuits D1 and D2 respectively of a control circuit that drives multiple styluses forming a matrix.

Title: Thermal head
Inventor: NAGAI KANJI
IPC: B41J2/38
Filed: 1980-09-27
Abstract: PURPOSE:To control a thermal printing density at a constant level by unitarily incorporating a temperature detection element and a switching element for preheating a thermal head by heat generated from the loss of a collector into the thermal head. CONSTITUTION:A thermistor 2 for detecting the temperatur of a thermal head itself and a transistor 1 for preheating it by heat generated from the loss of a collector are provided on the thermal head. When the temperature of the thermal head itself rises, the thermistor 2 detects the temperature thereof to lower the internal resistance. This causes a drop in the bias of a transistor 1 to decrease a base current. Hence, a collector current reduces to minimize the heat generated from the loss of the collector, resulting in a lower temperature of the thermal heat itself. When raising the temperature of the thermal head itself, the operation is reversed to always preheat the thermal head itself up to a certain temperature.

Title: Running power transmission gear for tractor
Inventor: KATAYAMA NOZOMI
IPC: B60K23/08
Filed: 1989-05-26
Abstract: PURPOSE:To facilitate turning performance with switch-over automatically made between four wheel drive and two wheel drive by providing an automatic switch-over means which automatically engages/disengages power transmission to a front wheel power transmission shaft based on the ground speeds of rear wheels. CONSTITUTION:A projected end 56 to which power is transmitted from the trailing end power transmission shaft of a change gear mechanism via an universal joint, a front wheel power transmission shaft and a universal joint 55, permits power to be transmitted to a driven body 37 via a spline shaft 30 of an outer package, the cam 39 of a drive body 41 and a slider 40 and both of clutch pawls 36, and also permits power to be furthermore transmitted to a right and a left front wheel via a front wheel input shaft 23. When the braking operation of one side rear wheel forces the ground speed of the other side rear wheel to be doubled at the time of turning a tractor, front wheels are pushed so as to be advanced, a gap is thereby made between the drive surface of the sliding cam 39 of the slider 40 and the drive surface of the sliding cam 39 of the drive body 41, this permits the slider 40 to be slid so as to come off from the clutch pawls 36 of the drive body 37 so that the front wheel are conditioned to no power transmission. After turning has been over, when the ground speed of the rear wheel is restored to normal ones, both of the clutch pawls 36 are meshed with each other so that the front wheels are conditioned to power transmission.

Title: Gas leakage preventing device of fuel cell
Inventor: OUCHI TAKASHI
IPC: H01M8/04
Filed: 1989-05-26
Abstract: PURPOSE:To restrain leakage of fuel gas and also prevent generation of detonating gas even when the fuel gas leaks by supplying air with pressure slightly higher in the range of water column less than 100mm than that of fuel gas and reaction air, to the inside of an outer box for storing a fuel cell main body. CONSTITUTION:Power generating operation is carried out by supplying a fuel gas controlled at a constant pressure approximating atmosphere to a cell stack 1 and at the same time dividing clean air sent from a blower 15 into reaction air 29A and seal air 29B by adjustment of a throttle valve 22, 26. Then, pressure of the reaction air 29A is controlled so that it almost equals that of the fuel gas, while pressure of the seal air 29B is controlled to a pressure slightly higher than that of fuel gas and reaction air in the range of water column less than 100mm. The seal gas pressure inside the outer box 20 is thus controlled to a value slightly higher than the reaction gas pressure and an external pressure is applied on the seal portion whereby leakage of the fuel gas is blocked to eliminate the danger of generation of detonating gas.
