Title: Structure used as measures against static electricity of integrated circuit
Inventor: SATOMURA TAKASHI
IPC: H01L23/62
Filed: 1989-11-30
Abstract: PURPOSE:To increase an effect of measures against static electricity without increasing a parasitic capacity by a method wherein a deep collector diffusion layer is formed in a collector region of a bipolar transistor. CONSTITUTION:A deep collector diffusion layer 16 is an N<+> diffusion layer which reaches an N<+> buried layer 2 from a collector contact region 14. Thereby, R1 [a resistance between the collector contact region 14 and the N<+> buried layer 2] out of a series resistance R1+R2 of a collector becomes a sufficiently small value. As a result, the series resistance of the collector can be regarded as only R2 [a resistance between a base region 6 and the N<+> buried layer 2]; the series resistance of the collector can be made small without making the base region 6 large. When static electricity is applied to an element as measures against static electricity in such a structure, an electric discharge is caused fundamentally by the same operation as in conventional cases. Since, however, the resistance of the collector is made small (R1+R2 is reduced to only R2), a voltage between an emitter region 7 and the collector contact region 14 is dropped, and the time required for the electric discharge is shortened.

Title: Logic circuit simulation system and tree-structured system logic element block identifier generation system
Inventor: SHOJI MINORU
IPC: G06F17/50
Filed: 1991-11-01
Abstract: PURPOSE:To speed up the simulation of a logic circuit and to obtain an identifier for a logic element block for it in simple procedure. CONSTITUTION:Based on the connection information of the logic element recorded in a logic element connection information recording means 1, a tree- structured logic element block division means 2 divides the logic circuit into tree-structure logic element blocks. A logic element block integrated evaluation means 3 generates the identifier for the logic element block having divided tree-structure and prepares a true value table for each logic element block having different identifiers. A logic circuit simulation means 4 performs the simulation of the logic circuit based on the connection information of the logic element recorded in the logic element connection information recording means 1 as well as the evaluation result of the logic element block integrated evaluation means 3. Thus, since the logic circuit is divided into the tree-structured logic element blocks and evaluated in a lump, the examination of the large-sized logic circuit can be performed at high speed.

Abstract: PROBLEM TO BE SOLVED: To secure power feeding to an electric product under the power storage state even if a commercial power supply is cut off and to use the card of a telephone set in a telephone box by making it possible to select the commercial power supply and the power supply of a power storage device through a switching device as required for the power feeding to the electric product. SOLUTION: In the power supplies for a telephone set and a lighting fitting, even when the power for an inverter 6 obtained by a solar battery 3 is stored in a power storage device 5, the stored power is DC and cannot be used as the power supply of the telephone set 2 directly. Therefore, the power is converted into the usable AC. A switching device 8 switches the power supplies of the telephone set 2 and the lighting fitting 16 to the commercial power supply 7 or the power supply of the power storage device 5 and has a terminal (a) for the commercial power supply and a terminal (b) for the power supply of the power storage device.  Then, an accident sensing circuit 9 senses the cut-off of the commercial power supply 7 at the time of services interruption such as the time of disaster of earthquake and the like, at the time of thunderbold and the like and switches the power from the terminal (a) for the commercial power supply to the terminal (b) for the power storage device automatically.

Filed: 1993-12-14
Abstract: PURPOSE:To decrease the dispersion in the oscillating frequency by designing a channel length of a specific MOS transistor (TR) sufficiently longer among MOS TRs being components of an input control circuit of a ring oscillator circuit. CONSTITUTION:A channel length of an NMOSFET 4 receiving a control voltage and of a PMOSFET 2 forming a current output section of a current mirror circuit is designed sufficiently longer among MOSFETs being components of an input control circuit 7 of a ring oscillator circuit 8. The channel length is designed so that its static characteristic is not affected in a tolerance of manufacture of the channel length in NMOSFETs 5, 6 and PMOSFETs 1, 2 and a channel width is designed large to a degree so as to compensate a current decreased by the channel length. Thus, even when the channel length and the channel width of the MOSFETs are in dispersion, dispersion in the oscillating frequency is reduced.

Abstract: PROBLEM TO BE SOLVED: To set an oscillating angle freely between 0 and the specified maximum angle. SOLUTION: An eccentric axis 6 is mounted eccentric from the rotation center on the end of a rotor 2 mounted on a main spindle 1. A clamp driving axis 3 is mounted on a disk 5 mounted on the eccentric axis 6 in such a position that it has the same eccentric distance from the center of the eccentric axis 6.

Title: X-ray exposure and applicable mask
Inventor: KATO HIDEO
IPC: G03F1/00
Filed: 1987-12-14
Abstract: PURPOSE:To restrain a mask from making the local temperature difference for exposure without shifting mask patterns thereby transferring the exposure with high precision by a method wherein the parts not irradiated with X-ray are exposed simultaneously or while previously being heated. CONSTITUTION:The images of mask patterns 3 are transferred to a resist film 9 on a silicon wafer 8 by scanning the images with X-rays (SOR beams) 5 picked up as slit beams. At this time, non-exposed regions (not being exposed) are heated or previously held in the specific high temperature state by supplying a conductive heat generating material 4 with power through the intermediary of terminals 6. In other words, the non-exposed regions are exposed while restraining the mask patterns 3 from making the local temperature difference due to the beam irradiation. Furthermore, the material 4 may be heated by irradiating it with infrared rays simultaneously with the X-ray slit beams during the exposure process instead of the power supply heat generation.
