Title: Internal combustion engine
Inventor: SAKATA SHINICHI
IPC: F02D45/00
Filed: 1998-10-02
Abstract: PROBLEM TO BE SOLVED: To prevent vibration from a drive system during drive of an internal combustion engine from being erroneously determined as variation in the speed of the engine, so as to prevent the air-fuel ratio of the engine from being enriched due to such erroneous determination. SOLUTION: A fuel injection quantity control means 22 sets a desired fuel injection quantity injected by a fuel injection valve 9 in accordance with a desired air-fuel ratio so as to control the fuel injection quantity in accordance with the desired fuel injection volume. Further, when unstable combustion is determined, a fuel injection quantity compensating means 27 compensates the desired fuel injection quantity in accordance with a variation in the speed of an internal combustion engine which is detected by a speed variation detecting means 23, so as to shift the air-fuel ratio into a rich air-fuel ratio range but when stable combustion is determined, the desired fuel injection quantity is corrected, so as to shift, this air-fuel ratio into a lean air-fuel ratio range.  However, when the engine is in a drive condition, an inhibiting means 28 inhibits compensation of a speed variation compensation coefficient KAC by fuel injection quantity compensating means 27.

Title: Power output circuit for digital signal
Inventor: KIYOTA SHIGEYUKI
IPC: H03K17/04
Filed: 1998-10-02
Abstract: PROBLEM TO BE SOLVED: To discharge accumulated at charge at high speed by using an inductance. SOLUTION: A resistance R1 and a transistor Tr1 are connected to the base of a current driving type power transistor. The base of a power transistor Tr0 is connected to an emitter through a resistance R4 and an inductance La. A transistor Tr3 is connected to the end connection of the inductance La and the resistance R4. The transistor Tr1 and Tr3 have the same polarity and are connected to a power supply source V1. When an L signal is inputted to the gate of the transistor Tr1, a base current is allowed to flow through the power transistor Tr0 to turn it on. The L signal is inputted to the gate of the transistor Tr3 just before the L signal is changed to an H signal and an inductance current is generated in the inductance La.  Because disconnection is made when the inductance current is turned off from the on state of the power transistor Tr0 to the off state, accumulated charge is discharged due to the continuity of the inductance current. It is possible to fast discharge the accumulated charge by setting the inductance current on a large scale.
Patent JP-S61158231-A (JP)
Title: Frame synchronizing method
Inventor: TAKAGI KIYOSHI
IPC: H04J3/06
Filed: 1984-12-28
Abstract: PURPOSE:To attain sure frame synchronization by adding a frame memory control part, a comparison value memory control part and a timer to decrease the time between the input of a digital signal and the detection of the frame synchronization. CONSTITUTION:A comparator 4 compares a correlation value 3 with the output (x) given from a comparison value memory control part 8. Then a frame synchronization detecting signal 5 is outputted if the value 3 is larger than the output (x). The signal 5 clears a timer 9 and also is supplied to a frame memory control part 7 and the part 8. Both parts 7 and 8 increase their outputs (l) and (x) respectively. If no signal 5 is outputted, a frame synchronization non- detecting signal 10 is outputted from the timer 9 to decrease said outputs (l) and (x) respectively. Thus it is possible to decrease the time between the input of a digital signal and the detection of the frame synchronization. This ensures the sure frame synchronization.
Patent JP-H02127748-A (JP)
Title: Memory test system
Inventor: SAKAI SEIKI
IPC: G06F12/16
Filed: 1988-11-07
Abstract: PURPOSE:To prevent the deterioration of throughput by transmitting a memory test end command when a test is through with a test of a pointed memory area. CONSTITUTION:A CPU 32 transmits a memory test request command including a test start address and the test start length of a test area to a diagnosing device 33. The device 33 executes the test of a main storage 31 and transmits a memory test end command to the CPU 32 when the test is over. The CPU 32 updates the test start address and decides the time of the memory test based on a task value to be processed, etc. Then the CPU 32 transmits a memory test request command again to the device 33 for the test of other areas. Thus it is possible to avoid such inconvenient cases where the CPU 32 is occupied by the memory test or the throughput is deteriorated due to the increase of the memory access time of the device 33.

Title: Semiconductor device
Inventor: MATSUDA JUNICHI
IPC: H01L21/8242
Filed: 1990-10-19
Abstract: PURPOSE:To form a first semiconductor layer flatly to form symmetrical source and drain by forming a contact under a second semiconductor layer and by providing no contact under the first semiconductor layer forming the active region of a transistor. CONSTITUTION:A first insulating film 4 is formed on a P-type semiconductor substrate 2 and a semiconductor layer 5 is formed on the insulating film 4. A quadrilateral region shown by an alternate long and short dash line is a first semiconductor layer 6 and a tongue piece is a second semiconductor layer 7, which layers are constituted by the integral layer 5. The layer 7 is connected with the substrate 2 via a contact C shown by a mark X formed in the film 4. Because the contact C is not formed under the layer 6 substantially forming an active region, the layer 6 can be formed flatly without irregularity. Therefore, even if a mask gap is generated at the time of forming a gate 9, a source and drain can be formed symmetricaly. Also, the contact C is formed under the layer 7, but the film 8 to be formed on the contact C is formed thickly so that neither transistor is constituted nor the formation of symmetrical source and drain is affected by the formation of the contact C.

IPC: G06F9/45
Filed: 1994-10-21
Abstract: PURPOSE: To use KANJI(Chinese character) variable names and function names by decoding KANJI in the state of compilation and generating an object. CONSTITUTION: This is the recognition algorithm of the C language compiler for KANJI symbols and KANJI is recognized only when two bytes are put in one byte and the front one byte and rear one byte are both in the range of KANJI codes, but when not, alphanumeric characters are decoded. The decoded symbols are registered in the symbol table of an object program. The use of the C compiler allows KANJI to be used for symbols and variable names and function names having distinctive meanings can be represented with a small number of characters as compared with the notation of Japanese with Roman characters; when a complicated program is generated, the burden on a programmer is lightened.
