Title: Cooling device for exhaust valve
Inventor: TAKAMOTO TADAO
IPC: F01L1/46
Filed: 1988-11-07
Abstract: PURPOSE:To make it possible to restrain the temperatures of the neck and head parts of an exhaust valve from increasing, by cooling the exhaust valve in such a way that the neck part of the exhaust valve in a seated condition is made into contact with a curved surface part of an inner guide. CONSTITUTION:When the head part 4a of an exhaust valve 4 is seated on a valve seat 3 by a drive device 10 upon completion of an exhaust stroke of an internal combustion engine, a curved surface part 7a of an inner guide 7 driven by the drive device 4 in a direction remote from the exhaust valve 4 (that is, the direction toward the head part 4a) abuts against the neck part 4b of the exhaust valve 4. With this arrangement, heat is absorbed from the neck part 4b whose temperature has been raised, by the curved surface part 7a making contact with neck part 4a. Further, the part around the center of the head part 4a is indirectly cooled due to the heat absorption from the neck part 4b. Such cooling can be made every one of intake, compression and combustion strokes, and accordingly, the exhaust valve 4 is driven by the drive device 10 in the direction in which the exhaust valve 4 is parted from the valve seat 3 upon initiation of an exhaust stroke, and further, the inner guide 7 is taken into upward from an exhaust port 2, thereby it is possible to prevent the exhaust efficiency from degrading.

Title: Information processor
Inventor: KIMURA KANEE

Filed: 1989-10-27
Abstract: PURPOSE:To improve the arithmetic processing speed by writing the arithmetic result into a data storage means when a data type deciding means decides that the dividend data shows a fixed length integer and then distributing the arithmetic result to the processes corresponding to the type of the dividend data when the this data does not show the fixed length integer. CONSTITUTION:When the divisor data 8 having the power of 2 is inputted to an arithmetic processor 5, the dividend data 9 is sent to the processor 5 from a register file 2. A data type deciding circuit 3 compares the tag value 6 of the data 9 received from the file 2 with the tag value 7 received from a microcode and decides whether the data 9 shows a fixed length integer or not. If so, the circuit 3 is allowed to write the arithmetic result of the processor 5 into a register write control circuit 1. Then the arithmetic result is written into the file 2. If not, a write inhibiting signal is sent to the circuit 1 from the circuit 3 for the arithmetic result of the processor 5. Thus the write of the arithmetic result is inhibited to the file 2. Then a microprogram control circuit 4 distributes the arithmetic result of the processor 5 to the proper processes in accordance with the type of the data 9. Thus the arithmetic processing speed is improved.

Title: Gain variable amplifying circuit
Inventor: KIKUCHI HIROYUKI
IPC: H03G3/10
Filed: 1989-10-30
Abstract: PURPOSE:To decrease the fluctuation of a drain-source voltage by connecting drains, gates and sources of 1st, 2nd FETs to a respective constant voltage source, connecting those of the 1st FET to one terminal of a resistor, a signal input terminal, a variable voltage source respectively and using the one terminal of the resistor as an output terminal. CONSTITUTION:When a source voltage VAGC is increased, the drain current of a 1st FET 4 is decreased, but the drain current of the 2nd FET 11 is increased conversely. When the source voltage VAGC is decreased, the drain current of the 1st and 2nd FETs is changed reversely to above. That is, the current of the 1st and 2nd FETs is changed reversely with respect to the change in the source voltage VAGC. Thus, it is possible to decrease the fluctuation of the drain-source voltage of the 1st FET 4 more than a conventional amplifying circuit with respect to the change in the source voltage VAGC. Moreover, since no excessive voltage is applies as a voltage VDS, the reliability is improved, as well.

Abstract: PURPOSE:To reproduce an input voice signal in an excellent way by devising a voltage across speaker coil terminals to be a voltage proportional to an input voice signal in the amplifier circuit used for a speaker driving circuit even when the speaker generates power. CONSTITUTION:An operational amplifier 2 is employed to compare an input voice voltage with an output voltage. That is, the output voltage is divided by using resistors 4,5 for the comparison with the input voltage and a voltage amplification factor.of the operational amplifier 2 is selected to be the unity. Concretely, a conventional resistor is used for the resistor 4 and a DC component resistance of a speaker is used for the resistor 5, and then a voltage amplification factor of a differential amplifier 1 is selected to be the unity by. the resistance as resistance of the resistors 4, 5/resistance of the resistor 5. A forward electromotive force is produced in the speaker 3 by driving the speaker 3 with the amplifier circuit formed as above, a voltage across the resistor 5 and the input voltage are compared with the amplifier 2 to feed back the inverted forward electromotive force to the amplifier 1. Thus, forward electromotive force and counter electromotive force produced in the speaker 3 are apparently cancelled producing a voltage proportional to the input voltage between speaker coil terminals.
