Title: Time interval measuring instrument and cell flow rate measuring instrument
Inventor: KUSAYANAGI MICHIO
IPC: H04L12/28
Filed: 1994-10-14
Abstract: PURPOSE: To measure a time interval in a wide range by performing a time interval arithmetic operation between the present time when a second event occurs and previous time stored when a first event occurs by complement subtraction. CONSTITUTION: The cell of a relevant VP is read out from previous time storage 62 in which the previous time LT passing last time is stored by header information sampled by a header information sampling part 61. Difference between the previous time and the present time Ta outputted from a time counter 64 is calculated by a differential arithmetic operation 65, and an arrival time interval DT can be calculated. The VP regulation cell interval T of an arriving cell is read out by a regulation cell interval storage part 63, and it is compared with the interval DT by a comparison arithmetic part 66. When the interval T is smaller than the interval DT when a flag Fo outputted from a flag storage part 68 shows zero or one, it is scrapped as a violation cell.  Also, when the former is larger than the latter, the cell is passed, and the time Ta is written on the storage part 62 as the time LT of a corresponding cell, and the flag Fo is changed to zero, then, it is written on the storage part 68. Also, when the flag Fo shows two, the cell is processed as no violation of cell unconditionally.

Title: Vehicular driving force controller
Inventor: MACHIDA KENICHI
IPC: F16H61/21
Filed: 1996-09-20
Abstract: PROBLEM TO BE SOLVED: To switch engine brake force even if automatic engine brake control is operated in downhill traveling, by controlling the gear ratio and the negative output so that the target driving resistance may be in such a range that vehicle driving resistance to be calculated according to the gear ratio of an automatic transmission can be generated.

When the target driving resistance Rt is larger than the maximum driving resistance RFx, the gear ratio is corrected to the one stage lower side to increase the gear ratio. When the target driving resistance is lower than the minimum driving resistance RFn, the gear ratio is corrected to the one higher side. In controlling to the new gear ratio NxrZr, the target throttle valve opening tTVO of an engine for obtaining target turbine resistance torque Tt by which the target driving resistance Rt can be achieved is calculated, the gear ratio and the negative output of the engine are automatically controlled in downhill traveling, and engine brake force is changed according to switching of ranges.

Filed: 1985-11-08
Abstract: PURPOSE:To quickly decide whether a wiring route exists between two points or not by using a barrier map comprising the bit data showing the presence or absence of wiring faults for each wiring basic grid. CONSTITUTION:A central processor 5 produces a cell map and a barrier map based on the connection information given from a keyboard device 2 and an input tablet device 3. The cell B of the barrier map has its vertical and horizontal sizes 5 times as large as a cell (a) and consists of the bit data showing the presence or absence of the wiring faults for each wiring basic grid. The presence or absence is detected on the barrier map of the 1st layer toward an arrow mark from points S and E. If the retrieving area is put on an axis X (part of X1), it is decided that no fault is detected with the 1st layer. Then the presence of a fault is retrieved with the 2nd layer. If no fault is detected, a concrete wiring route is decided between points S and E and displayed on a CRT picture display device 1. At the same time, a photoplotter 7 delivers the photographic pattern information for photomask.

Title: Fuel injection control device of engine
Inventor: SUZUKI MAKOTO
IPC: F02D41/12
Filed: 1983-12-26
Abstract: PURPOSE:To restrain variations in engine torque to improve the drivability of the engine, by providing such an arrangement that the minimum fuel injection amount is changed over at two points so that in comparison with the change-over point set during the phase of lowering of engine rotational speed from a higer speed, the change- over point set during the phase reverse to the above-mentioned phase is shifted to the high rotational speed side. CONSTITUTION:Upon operation of an engine, a control circuit 34 judges whether the rotational speed of the engine which is obtained from the output of a rotational speed sensor 32 is in one of two ranges which are sectioned by a first set rotational speed (for example, 1,600rpm) and a second set rotational speed (for example, 2,000rpm) or in the other one of the ranges, and determines a minimum fuel injection amount taupmin in accordance with the thus judged rotational speed range. Then a basic fuel injection amount taup is computed in accordance with the outputs of an air flow sensor and the rotational speed sensor 32, and is compared with the minimum fuel injection amount. When taup<taupmin, taupmin is selected, but when taup>taupmin, taup is selected as a final basic fuel injection amount, and therefore, the basic fuel injection amount is suitably compensated in accordance with the operating condition of the engine to obtain an actual injection amount for controlling a fuel injection valve 12.

Filed: 1987-10-05
Abstract: PURPOSE: To reduce noise and vibration at the time of starting without increasing the size of a motor by providing a first accumulator and a second accumulator arranged in a heat insulating material. CONSTITUTION: When a compressor 18 is stopped, refrigerant and oil 27 leak through the gap of a cylinder 18b, a piston 18c, or the like, at a mechanical section 18d to the low pressure side. The refrigerant flows through a return tube 25, a second accumulator 24 and a connecting tube 23 and then it is condensed sequentially by a cooler 21 and a first accumulator 22. The oil is stored only at the lower part of the return tube 25. At the time of restarting the compressor 18, liquid refrigerant is sucked instantaneously from the cooler 21 and the first accumulator 22 into the compressor 18 but only the gas refrigerant evaporated by the second accumulator 24 in a heat insulating material is sucked along with the oil 27 stored at the lower part of the return tube 25.  Since the second accumulator 24 can be embedded in the heat insulating material above the machine room, lift to the compressor is increased and the oil can be prevented from storing in the first accumulator.
