Title: Detecting circuit for input threshold voltage
Inventor: SOGI KOUJI
IPC: H03K19/00
Filed: 1983-11-14
Abstract: PURPOSE:To exclude a selection circuit and to reduce the chip area of an LSI by using a transistor TR of a small area in place of a TR of a large area and supplying directly a command signal. CONSTITUTION:When an input delivered to an external device I from an LSI11, a CPU15 turns on one of transistors Tr13 and off a Tr14. Then Tr11 and Tr13 are turned on when the input voltage is higher than the minimum value in an input voltage range. While a Tr12 is turned on when the input voltage is lower than the maximum voltage of said range. Then the logic 1 and 0 of the device  I can be sent to the CPU15 since the Tr14 is kept off. When an input is delivered from an external device II, both logic 1 and 0 can be sent to the CPU15 by the actions of Tr11-Tr14. Thus a partial area of the Trs constituting a conventional inverter is approximately equal to the entire area of Tr11-Tr14.

Title: Opening detector for engine suction air quantity controlling throttle valve
Inventor: NINOMIYA KAZUHIRO
IPC: F02B77/08
Filed: 1984-10-12
Abstract: PURPOSE:To eliminate impact load of a contact as well as to improve durability ever so better, by installing a dashpot, which turns the velocity of a rod moving toward the contact to a low velocity, inside a body, in case of an idle state detector. CONSTITUTION:A rod 4 is installed in a body 2 constituting an adjust screw of a throttle valve free of movement in an axial direction. In time of idling, the rod 4 comes into contact with a contact 5 and detects an idle state. At this time, capacity in a cylinder chamber 14 decreases, and oil in this cylinder chamber 14 flows out to a liquid chamber 13 little by little by way of an orifice 15 so that a piston 3 and the rod 4 move at low velocity by action of a dashpot. Thus, even if the throttle valve is suddenly closed, impact load is in no case added to the contact so that durability is improved.

Title: Spread spectrum communication equipment
Inventor: MORI SEIJI
IPC: H04J13/00
Filed: 1991-07-31
Abstract: PURPOSE:To prevent a data part from being erroneously detected as a burst part when the burst part can not be synchronized at the spread spectrum(SS) communication equipment adopting a burst transmission system. CONSTITUTION:At a transmitter, the signals of the burst part and the data part outputted from a transmitting power control circuit 5 are spread modulated and transmitted by various PN codes by impressing PN codes PN1 and PN2 various for a burst period and a data period to a modulation circuit 4 while switching those PN codes at a first switching means 3. At a receiver, a correlation equipment 14 correlates the received signals by the PN code PN1 for reference inverting the time of the PN code PN1 at the transmitter in the case of starting the communication of one packet and when a voltage comparator 17 outputs a burst detecting pulse according to this correlative output, the other PN code PN2 for reference is selected by switching a second switching means 19 according to this pulse. Therefore, even when the received signal of the data part is inputted to the correlation equipment continuously to the burst part, a correlation value is small between the PN code PN1 for reference and the PN code PN2 of the data part.
