IPC: F02B75/02
Filed: 1986-10-16
Abstract: PURPOSE:To eliminate the surging of a valve, thereby preventing the output or the part's life-span from being lowered or shortened, by arranging a rotary suction and exhaust valve, which is driven by the output from the engine, on the opening end part to the combustion chamber of a suction and exhaust manifold, which is connected to a combustion chamber. CONSTITUTION:A suction and exhaust and exhaust valve 3, which is rotatable and which is provided with a passage 4 therein, is arranged on an opening end part to the combustion chamber 1 in a suction and exhaust manifold 2 connected to the combustion chamber 1 of a 4-cycle engine.

Inventor: SUGITA MITSUYUKI
IPC: H03B5/32
Filed: 1989-09-22
Abstract: PURPOSE:To realize an overtone crystal oscillation circuit whose circuit constitution is simplified by constituting a high pass filter of capacitors and a resistor to reduce the number of components. CONSTITUTION:A 1st capacitor CP1, a 2nd capacitor CP2 and a 2nd resistor RG2 constitute a high pass filter, and when a crystal resonator CRS is oscillated in the 5th-order overtone, the cut-off frequency of the high pass filter is set between the frequency of the 3rd-order overtone and the frequency of the 5th- order overtone. An LC turning circuit comprising a coil and a capacitor is not required for the overtone crystal oscillation circuit. Thus, the circuit constitution is simplified, the number of components is reduced and the size is made small.

Patent JP-H07176744-A (JP)
Title: Semiconductor device
Inventor: ADORIANUSU UIREMU RUDEIKUUIZE
IPC: H01L29/06
Filed: 1994-10-13
Abstract: PURPOSE: To allow almost no increase in on-resistance when a switch is turned on, by locally reducing a distance between a back gate area and a first breakdown voltage increase area and not connecting the first breakdown voltage increase area with a breakdown voltage increase area wherein a conductive track extends in the upper part. CONSTITUTION: The interval between a region constituting a back gate 5 and a first breakdown voltage increase region 9A, which is positioned between the back gate 5 and a drain area 8 and is closest to the back gate 5, is locally reduced at a protruding part 35. Charges can be supplied or removed easily by such short interval. The first breakdown voltage increase region 9A is not connected with breakdown voltage increase regions 99A-99D wherein a conductive track 25 extends in the upper part. Thus, charges cannot be transferred from an inversion channel to the breakdown voltage increase region 9A. As a result, leak current is remarkably reduced or not generated at all.

Abstract: PURPOSE:To reduce the weight and dimension of a nongravitational lowering apparatus by reducing the width of a body frame by constituting a bucket member so as to be supported by a hinge and rising-restored in the folded state on the back side. CONSTITUTION:When a material A is loaded onto a foldable bucket member 4 installed onto a belt 3 by a hinge 4a, the bucket member 4 lowers because of the gravity of the material A.

Title: Current input type receiver
Inventor: OGASAWARA HIROSHI
IPC: H04B10/50
Filed: 1996-08-30
Abstract: PROBLEM TO BE SOLVED: To provide a receiver having wide versatility to various communication formats in a current input type receiver which is used for an optical communication system, based on infrared rays, for example. SOLUTION: A current/voltage coverting circuit 3 is connected through a capacitor C1 for coupling capacitances to a signal source circuit 2 comprising a photodiode 21 and a bias resistor 23 for forming a current signal source. A limiter amplifier 4 provided with a two-stage differential amplifier is connected to the output stage of the current/voltage converting circuit 3, further, a comparator 5 is connected to its output stage, and the block from the photodiode 21 to the input terminal of the comparator 5 is made into primary high-pass filter. Since there is capacitive coupling on the input side of the current/voltage converting circuit 3, the resistor 33 of the current/voltage converting circuit 3 contains no DC component so that conversion efficiency can be improved.  Therefore, since the gain of the amplifier on the following stage can be reduced, an offset voltage can be removed by trimming and since it is not necessary to provide capacitve coupling as a result, the place to set a time constant is only one.

Title: Interruption request control circuit
Inventor: UEHARA KAZUHIKO
IPC: G06F9/46
Filed: 1999-09-02
Abstract: PROBLEM TO BE SOLVED: To average the interruption requests by decoding the output of a priority encoder and outputting the decoded value of a channel, and outputting a process request having the decoded value retimed in response to the output. SOLUTION: A priority encoder 24 receives the output signal 39 of a 1st detector 23 and determines a channel 1. On receiving the signal 39, a decoder 26 outputs a signal 42 which is a decoded value as a channel where an interruption process has been performed to a control circuit 20. In response to the output signal 42 of the decoder 26, the decoded value is retimed by a 2nd storage means 27 and a process request of the channel 1 is reported to a host system 53. The host system 53 performs the process and then an interruption request generator 50 turns off the interruption request once, but instantaneously regenerates and turns on the request.
