Title: Picture data recording device and its method
Inventor: MAKISHIMA SUGIO
IPC: H04N5/7826
Filed: 1995-04-26
Abstract: PURPOSE: To record a still picture with high quality and a moving picture matching the conventional standard by a device capable of executing both of still recording and movie recording. CONSTITUTION: Picture data including 1280 picture elements in the horizontal direction and 960 picture elements in the vertical direction are obtained by a CCD11. IN a still recording mode, the picture data are compressed and recorded on a memory card(MC) to obtain a still picture with high quality. In a movie recording mode, the picture data including 1280 horizontal picture elements and 960 vertical picture elements are resampled by a resampling circuit 14 to obtain picture data having 720 horizontal picture elements and 480 vertical picture elements. The obtained picture data are compressed and recorded on a magnetic tape 8 matching the conventional standard. Since the band of picture data obtained by image pickup is wider than that of picture data to be recorded, resolution is not impaired even when filtering processing is executed for preventing the generation of folding distortion caused due to resampling processing.

Filed: 1985-06-07
Abstract: PURPOSE:To enable the reduction of the thickness of a semiconductor wafer by forming a resin layer on the wafer formed with a semiconductor device having salient-electrodes, bonding a resin sheet having an adhesive on the surface, grinding the back surface of the wafer, and then separating the resin layer and the sheet. CONSTITUTION:The periphery of salient electrodes 11 is buried with a resin layer 13 with resin on the surface of a semiconductor wafer 12 having the electrodes 11 on the surface. Then, a resin sheet 14 having adhesive such as polyethylene or polyester is bonded. The bonding is performed without retaining air bubbles therein. With the sheet 14 as a support the back surface of the wafer 12 is then ground by a back surface grinder to the desired thickness. The sheet 14 is separated, and the resist is removed by separating solution such as dichlorobenzene. Thus, since the surface of the wafer is flat in the first step, a protective sheet can be preferably contacted to prevent the sheet from separating at grinding time of the back surface.

Title: Method for detecting warping of plate material
Inventor: YOSHII MAKOTO
IPC: G01B21/20
Filed: 1991-04-26
Abstract: PURPOSE:To improve the computing accuracy of the warping degree of a plate material and to judge the warping direction effectively. CONSTITUTION:A plurality of coordinate data are obtained in a step 102. By using the obtained data, a plurality of regression expressions are obtained in a step 104. In steps 106 and 108, the regression expression having the maximum correlation coefficient is selected as the warping shape expression among a plurality of the regression expressions. The detection of the warping degree (warping curvature, warping height and the like) and the judgment of the warping direction 110 are performed by the obtained warping shape expression. In comparison with the regression of the warping shape with an arc which is obtained based on three coordinate data, the warping shape expression based on a plurality of coordinate data can regress the shape of the plate material excellently. Therefore, the computing accuracy of the warping degree is improved, and the warping direction is effectively judged.

Title: Method of controlling knocking for internal combustion engine
Inventor: TAKEDA YUUJI
IPC: G01H17/00
Filed: 1981-08-12
Abstract: PURPOSE:To enable to remve knocking condition of an engine promptly, by preparing at least two knock signal judging levels, i.e. a high judging level and a low judging level, and effecting ignition timing delaying control according to the level of knocking. CONSTITUTION:An interruption routine is excecuted at a predetermined crank angle and a MPU62 determines a datum ignition timing angle theta based upon the air intake amount Q and engine revolution speed Ne. At the same time, the MPU62 takes out peak values (b), (a) of knocking in the background and in the actual knock detecting period from a RAM64 and judges a >=k.b or not. If a >=k1.b, the MPU62 judges it as knock and sets an ignition frequency counter at n=O. Then, judgement is made by use of a larger value k2. Here, if a >=k2.b, it is judged as a high-level knock and correction on the ignition timing is increased by using a correction value obtained by subtacting, for instance, 2 deg. from the angle of a previous correction value k1 and delaying the ignition timing by adding Ok1-2 to the datum ignition timing theta. On the other hand, if a <k2.b, it is judged as a low-level knock and a minor correction is made on the ignition timing by use of a correction value obtained by subtracting, for instance, 1 deg. from k1.
