Title: Combustion chamber of internal combustion engine
Inventor: HASEGAWA KUNIO
IPC: F02F1/42
Filed: 1994-03-30
Abstract: PURPOSE:To enable suction tumbling to be surely formed by providing a restraining means on the inner wall of a combustion chamber along the outer circumferential part equivalent to almost a half circumference of a seat of the suction valve continuous to the curved inner circumferential part side of a suction port for the purpose to weaken the suction current in the gap between the inner wall and the suction valve outer circumferential surface. CONSTITUTION:Regarding those that have suction air tumbling formed on the inside of a combustion chamber 3 by a strong current produced on the curved outer circumferential part 2a of a suction port 2, a protrusion (or a cavity) is formed on the inner wall 3b of a combustion chamber 3 along the outer circumferential part equivalent to almost a half circumference of the seat 7 of a suction valve 5 in succession to the inner circumferential part 2b on thee opposite side of the outer circumferential part 2a of the suction port 2 as a restraining means to weaken the suction air current flowing through the gap between a suction valve outer circumferential surface 5a as much as possible. Thus suction air current flowing into the combustion chamber 3 not being able to follow the sharp formational change of the suction air port 2 at the protrusion 8 section but making partial disturbance is causing the suction air flowing through a gap b to reduce its flow velocity and enabling suction air tumbling flow to be formed for certain.

IPC: H03K3/84
Filed: 1981-04-21
Abstract: PURPOSE:To perform pattern generation with generating dummy cycle by making addresses for three patterns at the same time and preparing beforehand an address for jumping if there is jumping instruction in next two addresses. CONSTITUTION:Access is made in parallel to memories 2A and 2B, and next address is determined by command decipering devices 3A and 3B, and the program counters (PC) 1B and 1C are loaded for every two clocks.

Title: Speed checking device
Inventor: OMURA MASASHI
IPC: B61L23/34
Filed: 1996-02-22
Abstract: PROBLEM TO BE SOLVED: To allow the travel of a train at a speed suitable for its speed zone, properly absorb a substantial speed input error in a high speed zone and reduce train intervals in a low speed zone. SOLUTION: This device has a multiple configuration of systems 1 and 2 for comparing and checking train speeds 5 and 6 with limit speed patterns 3 and 4, and outputting brake instructions 23 and 24 for decelerating or stopping a train, when the train speeds 5 and 6 exceed the limit speed patterns 3 and 4. Regarding the device so formed, brake synchronous width is set, depending on the train speeds 5 and 6, so that the brake operation of one system 1 or 2 is detected during brake operation for lowering the limit speed patterns 3 or 4 of the other system by the prescribed value (brake synchronous width) and, then, lowering the limit speed patterns 3 or 4 at the time of synchronizing brake output.  That is, the brake synchronous width is calculated by multiplying the limit speed pattern 3 or 4 by a proportional factor, and adding a correction for a speed checking delay to the multiplied value. Furthermore, the limit speed patterns 3 and 4 are lowered by the calculated brake synchronous width, when the train speed exceeds the speed limit patterns 3 and 4.

Title: Ic card system
Inventor: MIYASHITA SHINICHI
IPC: G06K19/07
Filed: 1998-02-25
Abstract: PROBLEM TO BE SOLVED: To identify the using situation of an IC card in an IC card system for operating information communication by operating electromagnetic coupling between loop antennas by carrier waves by using an IC card and a reader/ writer, and amplitude-modulating the carrier waves. SOLUTION: For example, the opening and closing of a transistor T interposed between one terminal of a loop antenna 21 and a constant voltage source is controlled by a control means 25 so that a modulating means can be constituted in an IC card 2. Thus, only the polar components of one side of the carrier waves are modulated so that information can be transmitted to a reader/writer 1. In the reader/writer 1, a signal received by a loop antenna 11 is inputted through a coupling part 3 to a demodulating part 14, and the received signal is divided into components for each polarity by a detecting means constituted of a signal separating part 32, demodulating parts 33 and 34, or control part 15 so that the modulated signal for each polarity of the carrier wave can be detected.  In this case, the polarity obtained when the modulated signal is detected is made different according to the front and back surfaces of the IC card placed on the reader/writer so that the using situation can be identified.

Title: Paper feeder
Inventor: KAWASE JUNICHI
IPC: B65H1/26
Filed: 1989-03-15
Abstract: PURPOSE:To promote space-saving for a paper feeder by detecting a sheet mounting bottom plate or a loaded sheet top face when it is driven and lowered up to a sheet supply position, and also opening closing a cover at the more upper part than the vicinity of the supply position. CONSTITUTION:At the time of sheet supplying, a bottom plate 25 is once stopped at a position, where it is lowered as far as a portion of distance commensurate to a specified numbers of sheets 24, without lowering it at a stroke up to the lower limit. After supplying the sheets 14, the bottom plate 25 is lowered by a down switch (unillustrated herein), and when a paper detecting sensor 30 detects an upper end of each sheets 24, the plate 25 stops its descent and supplies a specified amount of sheets. With this repetition, the required supply takes place. Accordingly, since a sheep supply position comes upper than a lower limit detecting sensor 29, a cover 27 is set to setup height of the paper detecting sensor 30 and thus resupply can be done. Therefore a movable range of this cover is reducible in this way.
