Title: Semiconductor device
Inventor: SAIKI TAKAYUKI
IPC: H01L29/78
Filed: 1999-09-16
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor device which has a structure where the gate length of a field effect transistor included in a semiconductor circuit is not limited by the base width of a bipolar transistor included in a protective circuit. SOLUTION: The length L1 of a field oxide layer 18b is smaller than the length L2 of a field oxide layer 18c, so that an N-type region 14a is shorter than a N-type region 14b. Therefore, the resistance R1 of the N-type region 14a gets smaller than the resistance R2 of the N-type region 14b. By this setup, a current of static electricity is restrained from flowing through a MOS transistor 4 but made to flow through a bipolar transistor 2.

IPC: G06F7/53
Filed: 1988-10-18
Abstract: PURPOSE:To improve the arithmetic efficiency of a multiplication circuit by performing an arithmetic process to obtain the higher rank digit groups of an intermediate sum and an arithmetic process to obtain the products of the lower rank groups of the intermediate sum in parallel with each other. CONSTITUTION:Four partial products P00-P18 which are obtained from the algorithm of a booth are added together by an addition circuit 1. Thus the intermediate outputs S0-S14 and C0-C14 of the partial products are obtained. The intermediate sum signals S0-S5 of 6 lower rank digits and the carry signals C3-C5 are applied to a lower rank digit group addition circuit 2a out of those intermediate outputs. While other intermediate sums S6-S14 and C7-C13 of other higher rank digits are stored temporarily in a memory circuit 3. In this case, the 6 lower rank digits of the intermediate sum outputs are obtained earlier than other higher rank digits and therefore the product outputs Z0-Z5 of 6 lower rank digits and the carry output ZC are calculated and stored in the circuit 3 before the higher rank digits are calculated and stored in the circuit 3. Thus the parallel arithmetic processes are attained and the arithmetic efficiency is improved.

Title: Dust sensor
Inventor: HAYASHI MASAYUKI
IPC: G01N21/53
Filed: 1994-10-26
Abstract: PURPOSE: To measure the concentration of dust with high resolution over a wide range. CONSTITUTION: A light emitting element 1 is intermittently lighted, and a light receiving element 2 is arranged in a position on which direct light from the light emitting element 1 is not made incident. When dust enters a monitoring space in a sensor body, the quantity of receiving light of the light receiving element 2 increases by scattered light. Output voltage of an amplifying circuit 21 increases in a gradient according to the quantity of receiving light in the light receiving element 21 in a lighting period of the light emitting element 1, and decreases in a similar gradient in a lights-out period of the light emitting element 1.  A comparator 22 puts output on an H level in a period during which the output voltage of the amplifying circuit 21 exceeds reference voltage, and measures a time width of this H level by a time counter 23, and outputs the output value according to the time width from the time counter 23. Since the quantity of receiving light in the light receiving element 21 is converted into time and is measured by the time counter, the concentration of dust can be detected with high resolution over a wide range.

Title: Cryostat
Inventor: ONO MICHITAKA
IPC: H01L39/04
Filed: 1990-10-02
Abstract: PURPOSE:To inhibit the penetration of heat and avoid the clogging of piping by maintaining in the piping a gap through which gas flows and laying out a thin wall cylindrical vessel coaxially. CONSTITUTION:A vacuum cylindrical vessel 11 is coaxially laid out in a pipeline 7 used for the injection of very low temperature refrigerant 2, the collection of vapor gas, and the guide of current lead in order to prevent the generation of convection. The optimum value is available, which specifies the diameter, material, and thickness of the cylindrical vessel in conformity with the penetration heat of cryostats used. More specifically, when the diameter of a vacuum cylindrical vessel exceeds a certain level, the clearance between the pipe and the vacuum cylindrical vessel is narrower than a total thickness of a natural convection border layer which develops on the pipe wall of both the pipeline and the vessel, which inhibits the generation of downstream. On the other hand, it is desirable to take up a large gas flow passage cross section area as much as possible in order to protect the pipeline from being clogged. This construction makes it possible to prevent the introduction of hot gas in an ambient temperature section into a low temperature section and inhibit the penetration of heat from the piping.

Abstract: PURPOSE:To obtain a copy of a graph with less color irregularity and with high character quality by constituting title device such that the colored part of an original image can be image-formed at fixed copying density regardless of the color density. CONSTITUTION:In a normal mode an exposure control circuit 228 in an image processing device 250 controls the exposure quantities of three colors to form color images. According to that control, a color exposing device 300 exposes a photosensitive material S. In such a way color images are formed as latent ones in the area A of the photosensitive material S, and an area B is fully exposed to be white. The exposed photosensitive material S is sent to a heating and developing device 40, heated by a heating drum 44, and sent to a photosensitive image receiving paper overlapping device 70 in an outlet 56. When the leading edge of the photosensitive material S is detected, an image receiving sheet C is also sent to the device 70, and is further sent to a transfer device 88, where the color images in the area A are transferred onto the image receiving sheet c. The images in the area B remain white even if they are copied. A peeling-off device 90 isolates the pressurized and transferred photosensitive material S from the image receiving sheet C, both of which are set to a discarding part and a tray.
