Title: Memory control circuit
Inventor: UEDA TSUGIO
IPC: G11C29/00
Filed: 1978-08-22
Abstract: PURPOSE: To secure an assured switching to the auxiliary memory when the fault occurrence time by controlling the memory through production of the address decision signal with operation between the address and the upper and lower limit addresses.  
     CONSTITUTION: The address given from address inout buffer 6 is added to the lower and upper limit addresses of lower and upper address decision holding registors 1 and 2 via full adders 3 and 4, and adders 3 and 4 generate the carry signal of the highest-rank bit when the operation result becomes less and more than the lower and upper limit addresses each. And then an addition is given between the carry signal and the decision signal formed by the complements of digital 1 and 2 of lower and upper limit address decision holding registors 1' and 2'. Thus memory selection control signal 10 features a high level only when the address is within the upper and lower limit ranges. As a result, the selection for the auxiliary memory is controlled by signal 10 at the fault occurrence time, and thus the correction, replacement and others can be given to the faulty memory in the state under which other memories are operating.

Abstract: PURPOSE:To form a plated film on a wafer without warpage, crack at the wafer by measuring a direction and an amount of the warpage generated at the wafer, and forming the film with a current density generated at an electrodeposition stress for cancelling the warpage of the wafer based on its result. CONSTITUTION:A method for plating a semiconductor wafer to form a plated film 2 on a wafer 1 comprises the step of forming the film 2 with a current density for operating an electrodeposition stress of a direction for cancelling its warpage at a wafer 1 in which the warpage occurs in a compressive or tensile direction. For example, a plated film 2a is formed on an InP wafer 1 in which no warpage occurs by electrolytic Au plating. In this case, a current density is of the degree for operating a compressive stress to the wafer 1, the wafer 1 is removed from a plating apparatus, and the warpage of the wafer 1 is measured. Then, a plated film 2b is formed newly on a plated film 2a with a current density for so operating a tensile stress to the wafer 1 as to cancel the compressive stress.

Abstract: PROBLEM TO BE SOLVED: To dispense with facilities for manufacturing process and manufacturing environment cleaning and high accuracy by exciting a coil, driving a plunger on the main valve seat side by a latch mechanism, and driving a movable valve on the main valve seat side by a main compression spring. SOLUTION: When a coil 9 is excited, a plunger is once moved downward by a magnetic circuit formed out of a plunger 6, a first yoke 7, a second yoke 8, and a pole piece 13. By next demagnetization, it is moved upward by the force of a main compression spring 5. Then, the upper end side of a hook 24 is moved in a cam groove 23, so as to close the device. Under this condition, the main compression spring 5 is elongated, and a main valve rubber 21 is contacted with the underside of a main valve seat 1, so as to shut off a gas passage. Under this condition, the coil is excited again, demagnetized after moving the plunger 6 downward, the hook 24 is moved in the cam groove 23, so as to open the device. This is repeated at a fixed time.  This can be operated only by supplying exciting energy to the coil, and it dispenses with facilities for highly accurate manufacturing process and cleaning environment.

Abstract: PURPOSE:To reduce the number of pins during integration and to increase functions, by using a feedback clamping circuit, a Miller integrating circuit, and a comparing circuit in combination. CONSTITUTION:A Miller integrating circuit 41 is constituted by utilizing an easily integrated capacitance which has about 10 PF capacity. A video signal inputted through a transistor (TR) Q11 is supplied to the Miller integrating circuit 41 to remove a high-frequency color signal and a noise, and the resulting signal is inputted to a comparing circuit 42. The comparing circuit 42 compares a bias voltage with the input signal and during a synchronizing signal period, a TRQ15 turns on to rectify the output through the filter consisting of a resistance 44 and a capacitor 45, thereby feeding the result back through the buffer amplifier consisting of TRs Q13 and Q15. Consequently, the collector potential of a TRQ12 is regulated to make the DC level of a synchronizing signal constant. Further, a synchronous separating circuit 43 performs synchronous separation.

Title: Optical variable attenuator
Inventor: HAYATA HIRONORI
IPC: G02B6/00
Filed: 1989-04-21
Abstract: PURPOSE:To prevent an attenuation quantity from varying with wavelengths by the chromatic aberrations of a lens in a pair of optical coupling systems fixed with optical fibers in cylindrical sleeves by rotating one of the optical fibers aligned eccentrically to each other. CONSTITUTION:A pair of the cylindrical sleeves 14, 15 provided by eccentrically aligning the other end side to the center of the axis on one end side of the optical fibers 12, 13 in such a manner that the respectively eccentrically aligned fiber end face sides face each other. The one cylindrical sleeve 16 is rotated. Namely, the coupling efficiency is varied by the axis misalignment of the optical fibers 12, 13, by which the attenuation quantity is varied. Since the lens system is not used in such a manner, the influence of the chromatic aberrations is eliminated and the difference in the attenuation quantity by the wavelengths is decreased. The use of the attenuator without discriminating the same for short wavelengths and long wavelengths is thus possible.

Title: Producing method of semiconductor device
Inventor: MORI TAKAAKI
IPC: H01L21/316
Filed: 1978-08-25
Abstract: PURPOSE: To perform easy control of a base layer by driving ion after selectively changing a polysilicon layer into an oxidized layer when making a base area in a semiconductor area surrounded by an isolation oxidized film.  
     CONSTITUTION: A polysilicon layer is set on a semiconductor area surface surrounded by an isolation oxidized film formed by selective oxidization. after the polysilicon layer part except for an emitter area and a basecontrol part is selectively changed into an oxidized film, ion is driven through the polysilicon layer and the oxidized layer to form a base diffusion area. Since the oxidization of polysilicon is thus performed before the formation of the base diffusion area, the effect due to heat treatment is prevented and the control of seat resistance and diffusion depth of the base diffusion layer is easily performed. After the above process, the ion driving with the almost same thickness of the polysilicon and oxidized layers produces a uniform base diffusion layer.
