IPC: H01L21/68
Filed: 1986-09-09
Abstract: PURPOSE:To facilitate the exchange of a chuck plate by a method wherein a hole to be connected to an air-sucking hole which is used to attract the chuck plate by negative pressure is formed at a movable base and the air is sucked through the hole. CONSTITUTION:For positioning a chuck plate 10 more than one positioning pins 24 are installed on the upper surface of a Z-stage 12.

Title: Reference track position detecting device
Inventor: USUI KATSUO
IPC: G11B21/08
Filed: 1984-10-12
Abstract: PURPOSE:To improve the track position detecting accuracy of a magnetic recording and reproducing device such an electronic still camera by adjusting a position of a photodetector corresponding to a reference track position on a magnetic disc, with two-step constitution of rough adjustment by a linear motion and a fine adjustment by a rotational motion. CONSTITUTION:A photodetector 6 is installed to the side face of a head carriage 3 so that it moves in the linear direction along the direction of a feed screw 2 together with the head carriage 3. On the other hand, a light shielding body 9 is placed on the same shaft as the feed screw 2 so as to be rotated synchronously with the feed screw 2. Accordingly, when the photodetector 6 executes linear movement, also a light shielding part 92 of the light shielding body 9 rotates, and it advances into a groove 61 of the photodetector 6 and cuts off light, an output of the detector 6 drops suddenly. In this way, a reference track position can be detected with high accuracy.

Title: Data interpolating method and image formation system
Inventor: KAWABE TORU
IPC: G06T3/40
Filed: 1999-07-27
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of a part having both high sharpness and noise level and a part having both low sharpness and noise level and to prevent a picture quantity from being lowered by a moire phenomenon even when an interpolating point is close to a sampling point by almost fixing the square sum of interpolation coefficients at all the time regardless of a coordinate value. SOLUTION: On the basis of three sampling data in data streams sampled at spatial and timewise equal intervals, an image processing part 70 performs interpolating calculation for estimating data at any arbitrary point. The sum of the respective data and the interpolation coefficient to be used for product- sum operation is almost fixed to '1', the product-sum with respective sampling coordinate values is almost equal with the coordinate value of the point to estimate and the square sum of the interpolation coefficients is almost fixed at all the time regardless of this coordinate value. Even when the interpolating point is close to the sampling point, by introducing surrounding sampling values to the interpolating calculation in a prescribed ratio, smoothing operation equal with the intermediate point can be applied.

Title: Output control method for multi-cylinder internal combustion engine
Inventor: HASHIMOTO TORU
IPC: F02B75/18
Filed: 1989-08-18
Abstract: PURPOSE:To reduce periodic generation of noise by suppressing a generated output in a cylinder, positioned in one end part, in an explosion stroke of a cylinder positioned in one end part, in the case of an engine in which the cylinder, positioned in the one end part, is placed in the explosion stroke next after the cylinder positioned in the other end part. CONSTITUTION:In a six-cylinder V-engine E which is fired in the order of No.1, 2, 3, 4, 5, 6 cylinder, explosion is generated in the first cylinder next to explosion in the sixth cylinder, and a noise at this time is generated maximum. Then in an ECU25 which inputs output signals of an engine load sensor 22, engine speed sensor 23 and an idle switch 24 or the like, first whether the first cylinder is placed in the turn of firing or not is decided, when the decision is YES, ignition timing is delayed at the time of deciding an idle condition. A degree of this delay timing is determined being based on the characteristic previously stored in a map (ROM). Thus by suppressing an output generated in the first cylinder, hammering noise, in its turn, engine noise is reduced.

Abstract: PROBLEM TO BE SOLVED: To prevent fuel from overflowing during supplying of fuel into a fuel tank by actuating a fill-up warning means when full condition of fuel in the tank is determined in the condition that supplying of the fuel is being judged.

Title: Pressure reducer and attemperator valve
Inventor: MORII TAKAYUKI
IPC: G05D16/06
Filed: 1990-08-09
Abstract: PURPOSE:To efficiently reduce the temperature and pressure of steam with a simplified and inexpensive mechanism by connecting the primary side of a cooling water filling port in a valve means for cooling water to a cooling water passage and connecting a secondary side to the primary side of a pressure reducing valve part. CONSTITUTION:Since pressure on the primary side and the secondary side of the pressure reducing valve part 50 is guided to both sides of a pressure response member 53 through plural guide passages 51 and 52, the pressure response member 53 moves in accordance with a pressure difference between the primary side and secondary side of the pressure reducing valve part 50. The movement of the pressure response member 53 is transmitted to the valve means for cooling water 54 and the amount of cooling water supplied to the primary side of the pressure reducing valve part 50 changes. Steam in the pressure reducing valve is apt to become heating steam as the pressure reducing rate, namely, a pressure difference between the primary side and the secondary side is larger. Thus, heating steam can efficiently by attemperated by filling much amount of cooling water when the pressure difference between the primary side and the secondary side is large and filling small amount of cooling water in accordance with the small pressure difference when the pressure difference is small. Thus, the temperature and pressure of steam can inexpensively be reduced with the simplified mechanism.

Title: Image processing unit and image pickup device
Inventor: HIRASAWA KATAHIDE
IPC: H04N7/01
Filed: 1996-08-13
Abstract: PROBLEM TO BE SOLVED: To provide the image processing unit to obtain an image with high image quality even when part of the image is eliminated and the resulting image is expanded to convert a pattern size. SOLUTION: An image pickup face is moved relatively by a prescribed amount with respect to an object image formed on the image pickup face of a photoelectric conversion means 106 by a relative position moving means 101. An image signal obtained by the photoelectric conversion means 106 is stored in storage means 109-112 for every movement by the relative position moving means 101. A synthesis means 113 synthesizes image signals stored in the storage means to generate a synthesized image signal.  Thus, the synthesized image signal is an image signal sampled at a high sampling frequency based on the movement by the relative position moving means 101 and a part of the synthesized image signal is segmented corresponding to an aspect ratio different from an aspect ratio of the image pickup face from the synthesis image signal to generate a segment image signal and picture element information of the segmented image signal is rearranged and in the case of converting the information to have a pattern size equal to the aspect ratio of the image pickup face so as not to reduce the precision of the image after the conversion.
