Title: Wafer recovery device
Inventor: TANMACHI MITSUO
IPC: H01L21/677
Filed: 1997-05-20
Abstract: PROBLEM TO BE SOLVED: To provide a wafer recovery device which is capable of automatically recovering many simultaneously cut wafers one by one from a slice base, holding the wafers and automatically identifying normal wafers and defective wafers. SOLUTION: Wafers W held by the slice base S are separated one by one from the slice base S by a fixed abrasive grain wire 44. The separated wafer W is carried to a recovery part 18 by a first conveyor 46. In the carrying process, the shape of the wafer W is image picked up by a CCD camera 48, and the image data are outputted to a controller 50. The controller 50 image- processes the image data and identifies whether it is a normal wafer or a defective wafer. Then, on the basis of the identification result, the normal wafer and the defective wafer are recovered separately in the recovery part 18.

Title: Image output device
Inventor: HOSODA JUN
IPC: G06T1/00
Filed: 1995-05-29
Abstract: PURPOSE: To realize an image output device capable of outputting an image on a display screen while arbitrarily moving the image having a fixed size in dots. CONSTITUTION: Storage addresses on a two-dimensional address expression of bit map data of, for example, an A-plane are specified by specifying a leading address (Xmem, Ymem). a horizontal direction address width Xwidth and a vertical direction address width Ywidth. Besides, the display position on the display screen of the bit up data is specified by specifying a leading display position (Xdisp, Ydisp), a horizontal direction display width Xwidth and a vertical direction display width Ywidth. Thus, for example, when the bit up is wanted to be scrolled in a display range while fixing the display range on the display screen, the Xmem or the Ymem may be timewisely increased and decreased at a constant rate. Moreover, for example, when the display starting position on the screen is wanted to be changed, the Xdisp or the Ydisp may be changed.

Title: Ignition timing controller for engine
Inventor: KAKIZAKI SHIGEAKI
IPC: F02P5/15
Filed: 1991-05-31
Abstract: PURPOSE:To reduce torque shock at fuel return time after deceleration fuel cut by controlling a retard value damping control start time of an ignition time control means so that the larger a parameter amount related to fuel transport retard is, the more is may be retarded. CONSTITUTION:During engine operation, a spark plug 14 is impressed with predetermined ignition voltage through an igniter by means of an ignition control signal operated at an ECU 9 into which the output signals of a knock sensor 19, a boost pressure sensor 20 or the like are inputted, and ignites air-fuel mixture in a combustion chamber, and burns it. On the occasion of ignition time control at the ECU 9, as for a fuel return time after deceleration fuel cut, an engine ignition time is retarded by a predetermined quantity from a demand ignition time, and then, it is arranged that a retard value is damped gradually and return to the demand ignition time is made. And at this time, the setting of a retard value damping control start time is made so that the larger a parameter (an air intake pipe adhesion fuel amount, an engine water temperature or the like) related to fuel transport retard is, the more it may be retarded.

Title: High strength gypsum panel and production thereof
Inventor: KATSUTA RYUTARO
IPC: E04C2/26
Filed: 1994-06-13
Abstract: PURPOSE:To obtain a lightweight high strength gypsum panel having high rigidity and excellent in impact resistance by laminating a reinforcing layer composed of a thermoplastic resin panel compounded with a fiber in specific wt. content to the single surface or both surfaces of a gypsum panel. CONSTITUTION:A laminate 10 is obtained by laminating prepreg laminates 14, 15 on both upper and rear surfaces of a gypsum panel 11 and bonding a thin sheet like surface material 16 to the surface of the upper prepreg laminate 15 if necessary. The material resin of the laminates 14, 15 and the surface material is desirably the same resin. As the fiber compounded with the material of the laminates 14, 15, a synthetic resin fiber, a metal fiber and an inorg. fiber are designated. When the compounding ratio of the fiber becomes below 40% in a wt. ratio, since the flowability of the resin is increased at high temp., the shaping of the prepreg laminates becomes difficult and rigidity and abrasion resistance necessary as a panel are not obtained and, when the compounding ratio exceeds 80% contrarily, adhesiveness lowers and molding processing becomes difficult and, therefore, the compounding ratio of the fiber is set to 40-80%, desirably, 45-60%.

Title: Two-color image forming method
Inventor: TABUCHI KENJI
IPC: G03G9/08
Filed: 1987-05-27
Abstract: PURPOSE:To prevent generation of a mixed color fogging by intrusion of different toners by deciding the bulk sp. gr. of a 1st toner at the bulk sp. gr. smaller than the bulk sp. gr. of the 2nd toner. CONSTITUTION:The bulk sp. gr. of the 1st toner which is so set that the electrostatic chargeability changes slightly to a reverse characteristic side than the 2nd toner by the interaction of the 1st toner and the 2nd toner is made smaller than the bulk sp. gr. of the 2nd toner. The 1st toner intruding into a 2nd developer, therefore, hardly comes into contact with a carrier by expelling the 2nd toner having the larger bulk sp. gr. and the electrostatic charge quantity thereof depends only on the interaction with the 2nd toner. The 1st toner having no electrostatic charge quantity any more scatters in the form of powder fumes to the outside of a 2nd developing device and can be removed by air suction. The color mixing is, therefore, surely prevented and the generation of the mixed color fogging is prevented as well, since such 1st toner which adheres to an electrostatic latent image (image part) hardly exists even if the 1st toner introduces into the 2nd developer.

Title: Optical relative displacement detector
Inventor: IIDA TAKAHIDE
IPC: G01D5/38
Filed: 1988-05-28
Abstract: PURPOSE:To prevent the detection result of relative displacement from having an error by operating a rotary mechanism according to the quantity of the deviation in the phase difference between 1st and 2nd intensity signals from a reference value when the phase difference deviates from the reference value. CONSTITUTION:In a normal state wherein a 1st diffraction grating and a 2nd diffraction grating are parallel to each other, the phase difference between the 1st intensity signal which is the intensity signal of light passed through both gratings 22 and 24 and the 2nd intensity signal which is the intensity signal of 2nd light passed through the grating 22 and a 3rd diffraction grating is set to the predetermined reference value. When the parallelism between both gratings is inferior, the phase difference between the 1st and 2nd intensity signals deviates from the reference value, so the rotary mechanism is operated according to the quantity of the deviation to set the gratings 22 and 24 parallel to each other. In this case, when the relative rotational positions of the gratings 22 and 24 are normal, both intensity signals become in phase with each other. Therefore, the detection result of the relative displacement is prevented from having an error owing to inferior parallelism between the gratings 22 and 24.
