Title: Signal generator
Inventor: SHIBATA KAZUO
IPC: H03K19/017
Filed: 1986-04-09
Abstract: PURPOSE:To obtain an output signal having large drive capacity by using the output signal of an inverter circuit as an activation signal of a delay part. CONSTITUTION:When a precharge signal P1 has a fall and then an input signal 1 has a rise, the voltage of a node N3 is raised up to a level less than the power supply voltage. At the same time, transistors TRQ21 and Q24 are turned on and the level of a node 2 has a fall. The level of the N3 has a rise before a TRQ28 is turned off owing to a time delay secured with a TRQ27 turned on. When the TRQ28 is turned off, the level of a node N4 so far kept under an L level by the size ratio between the TRQ27 and Q28 rises up. Then the level of the N3 rises up to a level higher than the power supply voltage owing to the boot effect of a capacity C21. Thus an output signal of a power supply level is outputted. Then the delay time can be controlled easily and accurately since the N3 serves as the start signal of a delay circuit.

Title: Air conditioner for vehicle
Inventor: NUMAZAWA SHIGEO
IPC: B60H1/32
Filed: 1993-04-09
Abstract: PURPOSE:To prevent rough idling with simple, low-priced constitution while making the best use of energy-saving performance which is the forte of an external variable displacement compressor. CONSTITUTION:An external variable displacement compressor with the capacity adjusted by a control current (In) from an air-conditioning control circuit 32 is used as a compressor 22 forming a refrigerating cycle 11. The air-conditioning control circuit 32 judges whether a vehicle is in travel or in idle operation by the output signal of an engine control circuit 39, and during the travel of the vehicle, forbids the displacement adjustment of the compressor 22 by the control current (In) or limits it small. As a result, the engine intake air quantity required to stabilize the idling engine speed approximately coincides before and after the travel of the vehicle. During the idle operation, the displacement adjustment of the compressor by the control current (In) is executed, but this displacement adjustment is performed mildly within a range of enabling the follow-up of feedback control of idling engine speed.

Title: Comparing device
Inventor: NUMAMOTO TATSUHIKO
IPC: G10L21/04
Filed: 1993-04-09
Abstract: PURPOSE:To objectively obtain a difference in singing without being affected by the individual capability of a singer even when the singer changes to an easy-to-sing interval by correcting interval information on reference singing according to accompaniment interval information showing the interval of an accompaniment and comparing the corrected interval information with interval information on compared singing. CONSTITUTION:A reference singing interval detection part 11 detects the interval of the reference singing and a compared singing interval detection part 13 detects the interval of the compared singing. Then an interval information correction part 12 corrects the interval information detected by the reference singing interval detection part 11 by the accompaniment interval information and a comparison part 14 compares the corrected information with the interval information detected by the compared singing interval detection part 13 and outputs the comparison result. Consequently, even when the compared singing having the same interval as an interval-converted accompaniment is obtained as a result of the conversion of the interval of the accompaniment, the interval can normally be compared with the interval of the interval- unchanged reference singing, so even when the singer whose singing is to be compared changes the interval of the accompaniment, the interval comparison result is obtained without being affected by the interval change.
