Title: Semiconductor device
Inventor: MAEDA MIKI
IPC: H01L29/812
Filed: 1999-07-30
Abstract: PROBLEM TO BE SOLVED: To improve heat radiating characteristic of a semiconductor device by providing a plurality of recesses at the lower side of active element formed at the surface of the semiconductor substrate in the shape of lattice at the rear surface of the semiconductor substrate. SOLUTION: An FET 12 and a matching circuit 13 are formed at the surface of semiconductor substrate 11 and a plurality of recesses 15 are provided at the rear surface of semiconductor substrate 11 in the shape of lattice with an equal interval in the vertical and lateral directions. Even when the area of the aperture of the recess 15 is equal, the strength of the semiconductor substrate is increased in comparison with that of the structure where only one recess having a larger aperture area is provided just under the FET 12. When one recess is smaller, all cavities in the recess 15 are filled and such gaps generated in the recess 15 are reduced. Heat generated in the FET 12 is transferred to the carrier plate 21 via the gold in the recess 15 and thereby the heat can be radiated effectively.  Thereby, the operation temperature of the FET can be controlled to improve characteristic and reliability.

Title: Sheet splicer
Inventor: AIDA MASAAKI
IPC: B65H21/00
Filed: 1986-09-17
Abstract: PURPOSE:To release a sheet from positioning pins fitted in the sheet so as to make the sheet free, by pressing a resilient member supporting the sheet positioning pins, downward with the use of a pressing means when a lower stage hopper is returned to its original position. CONSTITUTION:Individual sheets 12 to be spliced are set in a lower hopper 2, and the leading end section 13 and the next folded two sheets are fitted onto sheet positioning pins 5. Then, the leading end of a continuous sheet 10 set on a partitioning plate 6 is superposed on the leading end section 13 in a shape as indicated by a broken line, and is fitted onto the sheet positioning pins 5. Further, a base paper piece is peeled off from the leading end section 13 to expose a bisurface adhesive tape onto which the trailing end section 11 is applied. After the application when a lower hopper 2 is pushed into an outer box 8, a resilient member 4 is pushed downward by means of a stationary plate 9 so that the sheet positioning pins 5 are released from ths sheet, and then retracted from the outer surface of a sheet splicer 1. Accordingly, the sheet is automatically released from the sheet positioning pins 5 so as to be free, thereby it is possible to complete the splicing in a short time.

Title: Image-processing method and device
Inventor: SAEGUSA HIROSHI
IPC: H04N1/405
Filed: 1997-07-28
Abstract: PROBLEM TO BE SOLVED: To perform multivalued error diffusion processing, without increasing the circuit scale despite increase of the number of scales by subtracting repetitively the arbitrary set value that is smaller than the largest number of scales from the input image data, until this data becomes smaller than its threshold. SOLUTION: The multivalued image data supplied from a scanner, etc., are inputted via an input terminal 1, and a 1st selector 2 selects the image data received from the terminal 1 or a memory part 5. The output value of the selector 2 is compared with the multivalued data, which are set at a control part 8 via a comparison part 3 in advance. Based on this comparison result, the value that is set in advance at the part 8 is subtracted from the output value of the selector 2 from a subtraction part 4. This subtraction processing of the part 4 is repeated until the input image data becomes smaller than its threshold. The output of the part 4 is stored in the part 5. An error diffusion processing part 6 applies error diffusion processing to the value that is reduced to less than its threshold as a result of the subtraction processing.

The return light is polarized by 90 deg. at a half mirror 13, and is introduced to the backward path, and is dispersed to three beams passing a beam dispersive optical device such as a modified Wollaston prism 23, etc. The servo error signal for focusing and tracking is detected by the beam in the center of the three beams, and the MO reproducing signal is detected by a right and a left beams. In such a way, a servo error signal detecting system and a reproducing signal detecting system can be constituted on the backward path introduced by one half mirror 13, and a signal detecting optical system can be unified in one system, then, it is possible to make an on-going servo error detecting optical system unnecessary. Also, the MO reproducing signal with a large distinction ratio and a high C/N can be obtained.

Title: Method and device for detecting camber of beltlike body
Inventor: KAWADA NORIYUKI
IPC: G01B11/30
Filed: 1987-09-02
Abstract: PURPOSE:To detect the camber direction of the beltlike body by emitting parallel light beams which differ irradiation angle to the beltlike body, detecting the smallest shield width, and comparing shield width values almost at the irradiation angle when the smallest shield width is obtained. CONSTITUTION:A light emitting device 2 which emits beltlike light and a light receiving device 3 are rotated to vary the angle of projection of a projection parallel light beam 4 to a steel plate 1, and the camber quantity of the steel plate 1 is found at the time of the smallest shield width when the tilt angle of the projection parallel light beam 4 is theta=0. Then when the projection angle is rotated by +theta, shield positions B and C move to B' and C' to widen the shield width. The shield width of downward camber is larger than that of upward camber and when they are rotated by -theta, on the other hand, the shift in the shield position of the upward camber is larger, so the rotating direction of the projection parallel light beam 4 and the extent of the variation of the shield position are detected to detect the camber direction of the steel plate 1.

Title: Automatic document feeding type copying machine
Inventor: MAEHARA SHIGEJI
IPC: G03G15/00
Filed: 1988-08-31
Abstract: PURPOSE:To shorten a time required for copying action by measuring a predetermined time after a detecting means detecting a leading edge generates a detecting signal. CONSTITUTION:After a detecting means DSD1 detecting at last the leading edge generates a detecting signal in the carrying direction of a document D supported by a supporting means 47. The signal generating means generates a counting signal in synchronization with the speed that the supporting means 47 carries a document. After a counting means measures a predetermined time based on the signal from the signal generating means, copying paper is started to be carried to a photosensitive body. In such a way, even if a document is freely supported by the supporting means 47 to perform reading and exposing actions, a picture on a photosensitive body can be surely transferred onto the carried copying paper. Thus, the period for reading the document can be shortened.
