Title: Plotting method by laser beam and marking device by laser beam
Inventor: SASAKI KATSUNORI
IPC: B41J2/44
Filed: 1994-04-08
Abstract: PURPOSE:To provide a plotting method requiring less handling time for measurement for positioning. CONSTITUTION:First, luminescent points are formed at three reference points (S1) and an oscillation angle at this time is obtained (S2). Angles between a laser beam and the respective reference points and distances between the respective reference points are also obtained based on the coordinates of the reference points (S3) and the angle formed between the laser beam and a plotting plane is obtained using a relation obtained by a sine theorem (S4). When this angle is obtained, a distance to the reference point can be obtained and consequently the coordinates of the origin of a scanning coordinate system are obtained (S5). Since the coordinate values of the respective reference points in the scanning coordinate system are obtained based on the result of the step 2, by substituting these values into coordinate transformation equations, a rotational transformation matrix is determined (S6). When the rotational transformation matrix is determined, transformation from the scanning coordinates to polar coordinates can be performed (S7).

Title: Air assistor for fuel injection system
Inventor: MORI EIJI
IPC: F02M69/00
Filed: 1988-03-25
Abstract: PURPOSE:To accelerate atomization of fuel in all driving area as well as to improve a mixed state with air by installing a passage being interconnected to a crankcase via a check valve, in an assist air passage as being situated at the more injector side than the check valve. CONSTITUTION:In an area large in differential pressure between the upstream of a throttle valve 6 and an intake manifold 3 in and around an injector 4, namely, a range small in opening of the throttle valve 6, assist air is guided through an assist air passage 8 from the upstream of the throttle valve 6 via a check valve 6. The differential pressure becomes lessened with the increase of the opening of the throttle valve 6, but internal pressure in a crankcase goes up, so that the pressure difference required for inducting the assist air is secured from the crankcase 1a with a passage 10. Consequently, even in such an area as high in boost pressure, an inflow of the assist air is realizable, and an atomization of fuel is accelerated at all driving areas, thus a mixed state between fuel and air is favorably keepable.

Title: Ignition timing controller for engine
Inventor: SUZUKI TAKASHI
IPC: F02P5/15
Filed: 1988-03-24
Abstract: PURPOSE:To control knock occurrence so effectively by compensating intrinsic ignition timing for retardation with a compensation value being set up according to the timing advance value of an ignition timing controlled variable prior to the detection if an acceleration driving state is detected from an idling area. CONSTITUTION:At an idle running area, ignition timing is variably controlled by an ignition timing control means C with a deviation A between idle desired speed preset by a setting means D and actual engine speed out of a detecting means B, and thereby it is accurately converged. On the other hand, when an acceleration driving state out of the idle running area is detected by an accelerating state detecting means G, an ignition timing compensating means F sets a retard compensation value conformed to the timing advance value of an ignition timing controlled variable prior to the accelerating state detection, and compensates intrinsic ignition timing being controlled by the ignition timing control means C in the retard direction within the specified period. Thus, any knock occurrence is effectively controllable.

Filed: 1990-03-23
Abstract: PURPOSE:To obtain a gettering-effect reinforced silicon substrate by forming an oxide film having the very thin film thickness on the rear surface side of a single crystal silicon substrate, depositing polycrystalline silicon on the film, and performing heat treatment at a specified temperature. CONSTITUTION:A single crystal silicon substrate (c) is heat-treated in the mixed gas of nitrogen and oxygen, and an oxide film having the very thin film thickness of 1.5nm is formed. Thereafter, polycrystalline silicon (e) is deposited. The heat treatment of the substrate is performed in nitrogen gas at 1,100 deg.C for one hour. Then, the very thin oxide film is separated and changed at the interface between the polycrystalline silicon layer and the substrate, and oxygen deposit (j) is formed. When the upper part of the substrate is contaminated with copper and the copper is diffused, a large amount of the copper is detected in the polycrystalline silicon layer and the region of the interface-oxygen deposit at the rear surface (b) of the silicon substrate. The amount of the copper in the region of the interface-oxygen deposit is about twice in comparison with the polycrystalline layer, and the gettering effect is reinforced. The thickness of the oxide film is 5nm or less. When 5nm is exceeded, the film is not changed into the oxygen deposit. As the heat treatment temperature, 1,100-1,200 deg.C is preferable. The island-shaped oxygen deposit having the diameter of 5-10nm can be formed at the entire interface between the polycrystalline silicon layer and the substrate under the above described conditions.

In addition, even if a heat generating resistor is arranged in place of the electro-mechanical converter element 12 and the ink is subjected to abrupt heat expansion by the abrupt heat generation due to an electric signal, similar action is obtained. Therefore, an on-demand type ink jet recording apparatus can be realized by a simple constitution and operation.

Abstract: PURPOSE:To make it suffice that equipments and software for switch board control are provided to only one of plural stations that needs switch board service instead of to all by executing the exchange of switch board control information through a packet switching network. CONSTITUTION:A switch board POS 31 transmits to a central processing unit CC 1, through the packet switching network 10, a terminal number allocated to each switch board as well as a call number sent by a register signal. Also, a speech path in the POS 31 is switched from a register signal reception circuit to a headset-side. The CC 1 knows which board answers which call by a call number that it 1 receives through a packet interface unit PKT 2. Thereafter, an operator accepts a callee's number and various kinds of service requests as speaking with a caller, and transmits these bits of information to the CC 1 via the network 10 with the call number for a reference key code. In the case information transmission from the CC 1 to the POS 31 is necessary, the information is transmitted to a corresponding POS through the network 10 via a PKT 2 in accordance with a terminal number. As a result, the number of equipments and the software can be saved.

Title: Detecting method for position of running truck

IPC: H04B5/00
Filed: 1979-06-11
Abstract: PURPOSE:To improve the detection precision and reduce the fetching number of detection points, by using plural sets of inductive radio detecting units and by shifting relation of their installation positions to detect the position of a running truck in the course of running. CONSTITUTION:A fixed-frequency sine wave is transmitted from oscillating station 1 mounted on a car, and the antenna position is detected by deciding whether sine waves received by a pair of conductors 3 on the ground are inphase or antiphase. In case that plural inductive radio position detecting units like this are used, the minimum detection unit is expressed by the interval of nodes of strands, for  example, in respect to two detecting units 4 and 5. If detecting unit 5 is used with  shift of the 1/2 of the minimum detection unit for detecting unit 4, the minimum  detection unit of the system becomes 1/2 of the original minimum detection unit.  When the number of detecting units is increased and they are used with shift of an  equal interval, the detection precision can be improved, and the fetching number of  detection points can be reduced.
