Abstract: PURPOSE:To change the open/close timing of an intake valve with simple constitution by interposing an elastic body which can position a sprocket wheel in its turning direction around its shaft in relation to an intake cam shaft, between the sprocket wheel and the intake cam shaft. CONSTITUTION:Compression coil springs 26 which can position an intake cam shaft 7 and a cam sprocket 11, energize the cam sprocket 11 and a flange part 20 in the opposite direction by an energizing force larger than the drive force of a crankshaft applied on the cam sprocket 11 until an engine r.p.m. reaches a preset r.p.m.. When the engine r.p.m. increases beyond the set value, the drive force applied to the cam sprocket 11 overcomes the energizing force of the compression coil spring 26 and the cam sprocket 11 makes turning movement by an angle alpha corresponding to the gap l between a stopper pin 25 and opening parts 23, 24 relatively to a flange part 20. Accordingly, when the engine r.p.m. increases beyond the set value, a phase difference takes place on an intake cam 9 and an event angle can be made larger.

Abstract: PURPOSE:To reduce both the packing area and the cost by using a memory and a register to secure functions equivalent to plural memories that merely satisfy the bus width of a microprocessor in case a memory is connected to a microprocessor having large bus width. CONSTITUTION:A memory access controller consists of a memory SRAM 103 having a 1st data bus 117, a central information processing unit 101 which has 2nd data buses 108 and 109 having the data bus width of an integer multiple as much as the width of the bus 117 of the SRAM 103 and also connected partly to said bus 117, and the registers 104 having bit length equal to the buses 108 and 109 of the SRAM 103 and in the number smaller than said integer by one. In such constitution, no packing is required for extra memories in case a memory is connected to a microprocessor having the large bus width.

Title: Amplifier
Inventor: HIGUCHI YASUO
IPC: H03F3/68
Filed: 1990-11-07
Abstract: PURPOSE:To reduce the offset voltage between output terminals by generating the offset voltage on the positive input terminal side of an inverted amplifier and offsetting the input offset voltage generated across the positive input terminal of a noninverted amplifier by using the offset voltage. CONSTITUTION:When input signals are impressed upon the positive input terminal of the 1st operational amplifier 1 from an input terminal 9, the signals are outputted to an output terminal 10 after amplification. The input signals also appear at the negative input terminal of the amplifier 1 through the imaginary short between both input terminals of the amplifier 1 and the signals are also outputted to the output terminals 10 after amplification by means of the 2nd operational amplifier 6. Then an input offset voltage is generated across the input terminal 9 by the electric currents flowing to the positive input terminal of the amplifier 1 and an input resistance 2, but an offset voltage of the same potential as that of the input offset voltage produced across the terminal 9 can be generated between both ends of the resistance 7 by appropriately selecting the values of the resistance and current source 8 connected to the positive input terminal of the amplifier 6. Therefore, the offset voltage between the output terminals 10 and 11 can be reduced.

IPC: G01R31/36
Filed: 1987-11-30
Abstract: PURPOSE:To accurately measure the life of a battery by changing oscillation frequency in accordance with a current value flowing out from a battery and counting and integrating the frequency to measure the current value flowing from the battery. CONSTITUTION:When a current value flowing out from the battery 1 is changed, voltage impressed to both the ends of a resistor 6 is changed and a voltage value 5a-2a and then a voltage value 8a-8b are changed, so that frequency appearing on the output 9a of a VF converter circuit 9 is also changed. Since the counting speed of a counter circuit 10 is changed, counting corresponding to the current value flowing out from the battery 1 is executed. An output 10a from the circuit 10 is applied to a digital comparator 12, and when a digital value 13a set up by a preset circuit 13 coincides with the output 10a, the circuit 12 outputs a coincidence signal to the output 12a. An alarm circuit 14 is driven by using the coincidence signal to output an alarm signal. Consequently, the life of the battery 1 can be accurately measured and the device can be prevented from generating malfunction.

Title: Inspection method for sheet-bonding part
Inventor: YUGE YOJI
IPC: G01M3/24
Filed: 1998-10-26
Abstract: PROBLEM TO BE SOLVED: To inspect a sheet-bonding part simply and at low cost by a method wherein a pressurized gas is blown against the boundary of the sheet bonding part, changes in the sound generated are captured, and bonding defect parts are detected. SOLUTION: While a pressurized gas (air) is being blown against a boundary 4 of a bonding part 3 of a sheet 1 to a sheet 2 from an air nozzle 5, it is moved from one end to the other end of the bonding part 3, and the bonding state for the entire length of the bonding part 3 is inspected. At this time, if there is a place in which the sheets 1, 2 are bonded insufficiently, since the pressurized gas flows to the circumference along the shape of the bonding part 3, sound which is characteristic of the state is generated. When a part which cannot be bonded or a part which is bonded insufficiently exists, since pressurized gas flows into the gas between the sheets, the flow of the gas is changed. A sound which is different from the sound generated in the normal bonding part 3 is generated. Consequently, the part in which the different sound is generated is specified as being a bonding defect part.
