Title: Reflected beam type optical coupling semiconductor device
Inventor: MARUYAMA YUTAKA
IPC: H01L31/12
Filed: 1985-02-06
Abstract: PURPOSE:To prevent an overflow on a resin seal, and to obviate a malfunction by upward projecting a partition wall from the top surface of the outer wall of a package case and forming a projecting edge for stopping a resin projecting to both element section sides at the nose of a projecting section. CONSTITUTION:A partition wall 2 in a packate case is projected upward from the top surface of the outer wall of the package case. Since grooves are formed on both sides in the projecting section 12, projecting edges 13 projecting to both sides are shaped at the nose of the projecting section 12. Since the partition wall 12 and the projecting edges 13 are shaped, there is the projecting section 12 and the projecting edges 13 function as a resin stop even when a sealin resin in quantity, in which an overflow is generated in a conventional position detector on a resin sealing, is injected in the manufacture of the little device, thus completely separating resin seal layers 7, 8 in both element sections, then resulting in no formation of continuous resin seal layers while crossing the projecting section 12. Accordingly, defective leakage as seen in conventional devices is reduced remarkably, thus preventing a malfunction, then improving the yield on manufacture.

Abstract: PURPOSE:To quicken the end of an operation at the occurrence of correctable error by moving an error content detected by an error detection circuit to an error correction circuit so as to continue a read operation and using the error correction circuit to discriminate the propriety of data correction. CONSTITUTION:Plural sector read instructions from a central processing unit 400 and a read data from a disk device 200 are transferred to a main memory device 500 by a disk controller 100 and inputted to an error detection circuit 30 and when a read error is detected, the error is loaded to the error correction circuit 40.

IPC: G01R23/06
Filed: 1978-02-24
Abstract: PURPOSE: To facilitate the setting of output current value and improve the matching with various load devices, by obtaining output signals synchronized with input pulse signals by using charging-discharging circuit.  
     CONSTITUTION: A circuit 200 is charged or discharged depending on an input pulse signal, and when the charging or discharging voltage determined by such charging or discharging action attains a specified value, it is judged in a circuit 300. Using this judging signal and the input pulse signal, signals synhcronized with each cycle of input pulse signal are obtained. Depending on these signals, a constant current output is obtained from a circuit 400. Besides, providing an input control circuit 500, the input is arrested, so that the charging and discharging operations may be done smoothly. As a result, regardless of the duty ratio of the input pulse width, the output current which always corresponds to the frequency accurately may be set freely, and the matching with various load devices may be done securely and smoothly.
