Title: Method of erasing reversible thermosensitive recorded image
Inventor: YOSHINO MASAKI
IPC: B41M5/36
Filed: 1992-09-04
Abstract: PURPOSE:To enable printing and erasing to be performed uniformly even in the case where reversible thermosensitive material is applied on a rigid substrate such as vinyl chloride card, or contrary to this, on a flexible substrate by placing a dry recording medium having recording images and an infrared ray absorbing member into close contact with each other and effecting infrared ray irradiation thereto. CONSTITUTION:A draft 7 printed out by PPC, an ordinary printer, and the like is prepared. A transparent invertible thermosensitive recording film 6 is put thereon, and the draft is placed in close contact therewith in a manner facing the thermosensitive recording layer downward. By adjusting the level of light and darkness and irradiating infrared rays, parts on the images of the thermosensitive recording layer react and become turbid, so that it is manufactured as an OHP draft intactly. Black paper is prepared as an erasing light absorber 4, and it is then put thereon. When infrared rays are irradiated by a source of infrared ray 1, black paper is heated, resulting in making the sheet transparent.

Title: Phase locked loop circuit
Inventor: ITAYA EIJI
IPC: H03L7/08
Filed: 1987-10-19
Abstract: PURPOSE:To attain a stable operation at the steady-state by providing a phase comparator section sending each control signal sequentially in the steady-state, a charge pump section operating an analog switch in response to each control signal and generating a control voltage of a voltage controlled oscillator and a delay means giving a prescribed delay to one of the control signals. CONSTITUTION:The phase comparator circuit 121 in the steady-state is operated in a way that each control signal is sent sequentially in response to lead/lag of a phase of an output signal of a voltage controlled oscillator 151 and an input signal and a charge pump section 125 keeps the control voltage at that point of time. Since the operation of the analog switch of the charge pump section 125 has an operation delay to each control signal, at least one control signal has a delay to make the output voltage stable against each control signal sent sequentially. Thus, the status of unstable output voltage due to simultaneous turn-on is avoided.

Title: Slide rail structure for power seat
Inventor: YOSHIMATSU SATORU
IPC: B60N2/02
Filed: 1998-09-17
Abstract: PROBLEM TO BE SOLVED: To ensure sufficient strength and to suppress cost and weight in a slide rail structure for a power seat. SOLUTION: This slide rail structure for power seat is provided on a slide rail 5 with a load transmission means 11 engaged to support load in the longitudinal direction of a vehicle when an upper rail 5A and a lower rail 5B are relatively moved by load input in the longitudinal direction of the vehicle at the time of a collision or acceleration/deceleration of the vehicle. There is therefore no need to take a reinforcing countermeasure such as thickening plate thickness and enlarging the diameter of a lead screw 8 to prevent deformation, and weight can be reduced, being advantageous in cost. Moreover, collision load can be transmitted by the load transmitting means 11, so that input to a gear box 7 of a driving part 9 can be reduced. The gear box 7 can therefore be miniaturized so as to be further advantageous from the viewpoint of both weight reduction and cost.

Title: Driving circuit for diaphragm
Inventor: TANAKA HIROKAZU
IPC: G03B9/02
Filed: 1988-10-21
Abstract: PURPOSE:To have enough driving force and to obtain an inexpensive diaphragm device driving circuit with a simple constitution by providing first power supply circuits which supply power to a first shape memory alloy in response to a first selecting signal, and second power supply circuits which supply power to a second shape memory alloy in response to a second selecting signal. CONSTITUTION:When a light receiving value of a light receiver 26 which receives light of an object does not reach a standard value, a comparing and selecting circuit 28 outputs the first selecting signal. The first power supply circuits 30, 32 and 34 supply power to the first shape memory alloy 21a, it is heated and its temperature rises. As a result, shrinkage force arises when alloy returns to its original shape to open the diaphragm. On the other hand, when the light receiving value of the light receiver 26 exceeds the standard value, the comparing and selecting circuit 28 outputs a second selecting signal; moreover, the second power supply circuits 31, 33 and 35 supply power to the second shape memory alloy 21b. In this case, shrinkage force arises in the second shape memory alloy 21b to close the diaphragm. Therefore, an electric diaphragm driving circuit whose driving force is relatively large can be obtained as an inexpensive device with a simple constitution.

Title: Electrodeless lamp
Inventor: MINAMIMURA YUICHI
IPC: H01J65/04
Filed: 1996-10-04
Abstract: PROBLEM TO BE SOLVED: To prevent deviation of an operating point by generating strong plasma discharge in front of a lamp, increasing illuminance just immediately the lamp and simultaneously preventing current from being flowed to instruments by arranging an exciting coil to be turned sideways in the mounting direction of a base. SOLUTION: A lighting circuit 3 within a valve 1 excites high-frequency high voltage with power from a base 4 and conducts voltage to an exciting coil 2. When current is flowed in the exciting coil 2, magnetic flux alternately changing at a frequency of 2 to 3MHz is generated. At this stage, this exciting coil 2 is arranged to be turned sideways in the mounting direction of the base 4. As a result, strong plasma discharge is generated in the direction of 90 deg.C to paper, and illuminance immediately under the lamp is increased. Further, when the lamp is mounted on a metal instrument, current is not flowed to the instrument, an operating point is not deviated and the necessity for mounting a wire net on the lamp is eliminated. Thus, illuminance immediately under the lamp can be increased by arranging the exciting coil 2 to be turned sideways.

Filed: 1987-10-20
Abstract: PURPOSE:To prevent developer from dropping so as not to stain the inside of a device by forming an inner projection part which is made closer to a developer carrier on a part of a developer receiving part. CONSTITUTION:The developer receiving part 125b is formed on the aperture part of the edge of an upper casing 125 and the inner projection part 125c which is made closer to a developing sleeve 111A is formed on a part of the developer receiving part 125b. Since the developer which drops from a part where the developing sleeve 111A and the surface of a photosensitive drum 25 are close is received by the developer receiving part 125b and also the developer which moves to the direction of the aperture part with the carrier force and gravity from the carrying member is interrupted with an interruption effect by the inner projection part 125c and a magnetic roll 121A, it does not move to the developer receiving part 125b. Thus, the drops of developer from the aperture is removed, so that the stain of the inside of the device caused by the scatter of the developer can be prevented.

Filed: 1987-10-20
Abstract: PURPOSE:To reduce the load of an external device by separating a first-in first-out (FIFO) memory for storing a command written by the external equipment from an FIFO memory for storing a command acquired by command fetching operation. CONSTITUTION:A command written from the external equipment is stored in either one of two FIFO memories 7, 8.

When command fetching operation is specified by the decoding, its information is set up in an operation mode specifying flag storing part 11 and the selector 9 is switched. Then, a command fetch control part 4 is started and a command acquired by requesting command acquisition to a data transfer control part 12 is stored in the other FIFO memory. Since the selector 9 is switched, the command acquired from the external memory is read out to the command register 2 and decoded.
