IPC: B60W10/10
Filed: 1988-09-30
Abstract: PURPOSE:To prevent the driver of an industrial vehicle from sensing a delay in data treatment for checking insufficiently prepared control data by updating the check sum every time each piece of the control data in a memory is re-written. CONSTITUTION:When a normal study mode is to be set, a CPU 41 emits a sensing signal corresponding to current study point from a clutch position sensor 10 in order to put a dry type single disc clutch in properly engaged condition, and the study point is indexed, and the check sum of each control data corresponding to the study point stored already is implemented before writing in the memory region of an operating memory 44 as a control data. The reference study point is calculated on the basis of the control data thus written, and the reference stroke amount for this reference study point is calculated and determined in order to set proper clutch engagement condition. This prevents the driver from sensing eventual processing delay when insufficient preparation of different control data for running control is subjected to processing for checking.

Title: Air conditioner
Inventor: IGA NAOKI
IPC: F24F1/00
Filed: 1986-10-17
Abstract: PURPOSE:To reduce the load and room temperature fluctuations due to the ventilation and reduce the running cost by providing an auxiliary heat exchanger on the air conditioning ventilation fan side in the air intake passage downstream of a total heat exchanger so that when the outside air is taken in, the air whose heat has already been recovered is further cooled (under cooling mode) or heated (under heating mode) before being supplied into the room. CONSTITUTION:Space cooling or heating is performed between an outdoor unit 30 and an indoor unit 38 by a heat pump type refrigerating cycle. On the air conditioning ventilation fan 41 side, the heat is recovered in a total heat exchanger 42 from the discharged room air. Since the recovery rate is about 70%, the air whose temperature is higher than the room air temperature flows in under space cooing mode, and the low temperature air under space heating mode. By being cooled or heated in an auxiliary heat exchanger 46, the air whose temperature is nearly same as the room temperature is supplied from a room air inlet 54. Just like an indoor heat exchanger 39, the auxiliary heat exchanger 46 acts as evaporator under cooling mode and condenser under heating mode so that air may be cooled or heated by the auxiliary heat exchanger 46 and supplied to the room air inlet 54.

Abstract: PURPOSE: To prevent a multifunctional telephone device, used for the integrated service digital network(ISDN), from being in a free state. CONSTITUTION: The telephone device 12 sends and receives data to and from a digital control unit through a digital interface 44. When data is neither sent nor received or when the telephone device is not in operation, data output 52 is held high and the telephone device is made inactive.

Title: Program steering method for automated guided vehicle
Inventor: ITOU MOROTAKE
IPC: G05D1/02
Filed: 1995-09-27
Abstract: PROBLEM TO BE SOLVED: To execute slipless stable traveling at the time of executing programmed steering control on a traveling route having no guide line. SOLUTION: An automated guided vehicle 1 detects guide lines 10a, 10b on respective traveling routes on which the guide lines 10a, 10b are respectively laid and executes guide steering control so as to travel along the guide lines 10a, 10b. In a section B having no guide line, the vehicle 1 reads out a steering angle corresponding to a traveling distance from a program and executes program steering control so as to conform the read angle. When acceleration obtained by differentiating the read steering angle twice is larger than a set angle, traveling speed is reduced to prevent the occurrence of slip.

Abstract: PURPOSE:To prepare test information by a method wherein the intrinsic pulse signal is switched to a high-speed reference CP signal by a signal to be used exclusively for the test, the test information is outputted, a trouble signal which can not be detected by switching is focussed and outputted to other terminal. CONSTITUTION:A NOR gate 20 and the frequency dividing circuits of FF21-23 are operated by a reference CP2 when the signal 1 is '0', the output of the FF22 and 23 is added to an AND gate 24, and a six-demultiplying signal 9 is outputted to the reference CP. A signal 3 exclusively used for test is inputted to an AND-OR gate 26 together with the input 11 of an inverter 25, and signals 2 and 9 are switched and outputted 12. The intrinsic operation mode is obtained with the test information preparing mode '0' when a signal 3 is '1', and in the test mode, the test information of FF27 and 28 is outputted 14 to an output information bus 14 more quickly than the intrinsic operation mode. Also, when the signal 3 is at '0', the output 12 of the gate 26 is outputted 15 through the intermediary of an AND gate 29, and the signal necessary for preparation of test information is focussed and outputted by the gate 29, thereby enabling to suppress the increase in number of terminals and to prepare the test information of a high rate of detection.

When a side frame 2 of bending roll machine is in an upsetting state, for instance, an oil flows into the opening 15 through pilot and slot check valves 25, 26, by changing the valve 23 to the rising direction of frame 2. Then an upward force is provided to a piston 13 and the cylinder 12, but only the piston 13 rises to the upper limit because the valve 29 stops the reverse flow of an oil in an upper chamber 18, and the cylinder 12 rises later because the oil returns when the hydraulic pressure in the chamber 18 exceeds the set pressure of the valve 30. Then the frame stands up; and it upsets by changing the valve 23.
