Filed: 1985-09-04
Abstract: PURPOSE:To uniformize writing characteristics by reducing the emitter area of a memory cell disposed at far distance from a collector contact smaller than that of adjacent memory cell to the collector contact. CONSTITUTION:A relatively high impurity density N<+> type buried layer C is formed on a P-type semiconductor substrate 12, and the end is connected through collector electrodes C1, C2 with a row line W1. A base region Bi (i=1-4) is formed adjacently to a relatively low impurity density N<-> type semiconductor layer C0 on the layer C, and an emitter region Ei is formed in the base region Bi. An N-P-N transistor Qi of open base is formed of the layer C, the base region Bi and the emitter region Ei. Only the emitter areas of memory cells Q2, Q3 disposed far distance from a collector contact are reduced smaller than those of adjacent memory cells Q1, Q4 to the collector contact.

Title: Method and device for controlling display
Inventor: NAKANO MAKI
IPC: G09G5/00
Filed: 1999-07-09
Abstract: PROBLEM TO BE SOLVED: To detect an error in address data in which the influence of a data error is great and to prevent erroneous plotting processing. SOLUTION: When address data related to a display position in a displaying part for image data continuously transmitted a plurality of times is inputted, the address data is latched to a flip-flop 31, and an EXOR gate 41 compares an output of the flip-flop 31 with the next inputted address data. In the case these data do not coincide perfectly, a signal of a high level is outputted through an AND gate 42 and makes an error signal 44 a high level. When the signal 44 is returned to a controlling part, the controlling part resends the address data. Thus, image disturbance owing to an error of the address data can be prevented.

Title: Transaction control system
Inventor: NAKANO TOMOYA
IPC: G06F15/00
Filed: 1989-07-28
Abstract: PURPOSE:To optionally set up the size of a transaction area without restricting it by allowing the addresses of a transaction access area to correspond to that of a real transaction area and accessing the real transaction area. CONSTITUTION:A central processing unit(CPU) 1 sets up the correspondence of addresses between the real transaction area 12 to be used and the transaction access area in a memory control unit 4. When the CPU 1 specifies the address of the transaction access area, the memory control unit 4 converts the address into the address of the set real transaction area and accesses the real transaction area 12 in a memory 7. When an address other than the addresses of the transaction access area is specified, the memory 7 is directly accessed without converting the address. Thus, the real transaction area can be optionally set up.

Abstract: PURPOSE:To detect an orientation flat of a semiconductor wafer without bringing a mechanical detecting means into contact with the outer periphery of the semiconductor wafer by detecting a maximum value of electric signals for detecting the center of the wafer. CONSTITUTION:Radiation from a light source 2a is converged by a light feeding lens 2b into an optical beam 2c, which makes an optical spot A on the outer periphery 1b of a semiconductor wafer 1 rotating around the center 1c of the wafer while the position of the spot A may be varied in a range from (a) to (b) to (c) in accordance with a position that an orientation flat 1a takes. Reflected light 2f from the optical spot A is converged by a light receiving lens 2e and makes an optical spot B on the surface of an optical position detecting means 2d. An image forming position of the optical spot B is moved over the optical position detecting means 2d in accordance with an amount of displacement of the optical spot A on the outer periphery of the semiconductor wafer 1.
