Patent JP-H10242440-A (JP)
Title: Semiconductor device and its manufacture
Inventor: HASHIMOTO RYUSUKE
IPC: H01L21/762
Filed: 1997-02-28
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor device including a bipolar transistor with low parasitic capacitance between collector and base, excellent in high-frequency characteristics, and a method for its manufacture. SOLUTION: A semiconductor supporting substrate 2 with first and second insulating films 3, 4 formed between the substrate and a single-crystal semiconductor layer 1, is used. An element including a bipolar transistor is formed in the single-crystal semiconductor layer 1. Part of the region of the first insulating film 3 direct under the element is removed, and semiconductor 12, such as polycrystalline silicon, is buried in this defect. The buried semiconductor 12 is constituted as collector buried layer 12a. Since the collector buried layer 12a is formed only in the necessary region from a collector lead-out region 12b to the region direct under the emitter region 10, the parasitic capacitance between collector and base is reduced.

Title: Learning system
Inventor: SATO TOSHIO
IPC: G06N3/06
Filed: 1996-01-29
Abstract: PROBLEM TO BE SOLVED: To increase a storage amount with an external pulse frequency, and shorten an output generating operation time from a slow state and then vary the time to slow operation this time when the storage amount increases exceeding a half. SOLUTION: When an input pulse is generated by external stimulation, it is converted to size corresponding to the storage quantity and held. The held input pulse attenuates with time. When the holding attenuates to a threshold level as a certain time is elapsed, an output pulse is generated as a result of comparison. The output pulse is made twice as large as the threshold value, so the attenuation time becomes always constant. The input pulse is controlled to become small or large as the storage amount increases. Therefore, it takes a long time to generate the output pulse in the beginning, but the time becomes short as the storage amount increases. When the storage amount further increases, the time up to output is made long to the contrary.

Inventor: OTANI MASAMI
IPC: H01L21/304
Filed: 1999-02-23
Abstract: PROBLEM TO BE SOLVED: To make efficiently removable particles sticking to the surface of a substrate. SOLUTION: A washing brush 9 is provided with a washing portion 9c for washing a substrate, the holding portion 9d of the washing portion 9c and a support portion 9e. The washing portion 9c is constituted of a plurality of brush parts 9a, 9b which are respectively formed of a plurality of brush materials 19a, 19b different in wire diameter. Therefore, the brush parts 9a, 9b are different in rigidity. When the washing brush 9 comes into contact with the rotating substrate, since the friction forces acting on the particles sticking to the surface of the substrate from the brush parts 9a, 9b are different for every brush part of brush parts 9a, 9b, various particles can be removed from the surface of the substrate at the same time.

Title: Recounting device for digital display counting scale
Inventor: EMOTO SHINSUKE
IPC: G01G19/42
Filed: 1980-04-08
Abstract: PURPOSE:To eliminate the effect of quantization errors on the calculation of the number of measured samples to perform accurate counting by counting an unknown number using the weight of a known number as unit and counting when the error of the individual sample becomes smaller than one. CONSTITUTION:Samples of a known number N1 are mounted on the scale tray 1 to measure their weight W1, while the number of the samples, N1, is input (6) and a unit weight U=W1/N1 is calculated by the CPU. Next, by measuring the weight of S6 (Step 6) when sample number is increased to N2 and calculating the number from the unit weight, an alarm is displayed (7e) when the number becomes N2<= D1-1 (D1 is the count number of N1). Then the number of samples is decreased, the unit weight is recalculated and substituted. Repeating these procedures, the number of samples can be counted without producing even one count error in principle.

IPC: G21C7/16
Filed: 1978-04-21
Abstract: PURPOSE: To accomplish alternate operation of inserting and withdrawing the control rod every notch by means of an auxiliary memory relay provided for the action signal contact of the sequence timer.  
     CONSTITUTION: An auxiliary memory relay 44 is provided for the action signal contacts 33-1 of the sequence timer 38, while the normaly closed contact 45 of the relay 44 is connected in series to a control switch 31. Even if the subsequent operation is performed by the control switches 31, 34 and 35 during the action of the action signal contact, as the contact 45 of the relay 44 cuts the control circuit, an insertion control relay 36 or a withdrawal relay 37 is only excited during the operation of the action signal contact of the sequence timer 38. Thus, the operation of the control rod is completed only in one initial cycle.

Title: Method for controlling learning of industrial robot
Inventor: ARIGA TAKETO
IPC: G05B19/4155
Filed: 1988-02-29
Abstract: PURPOSE:To improve learning efficiency and to stabilize action by obtaining not only a positional deviation but also the deviation between a reproducing speed and a target speed and modifying a teaching value at the time of a next reproducing action based on the deviations. CONSTITUTION:In addition to the deviation between a target position and a reproducing position, the deviation between the reproducing speed and the target speed is obtained and the contents (teaching value) of a teaching value memory 2 is modified by the deviations. A target value memory 1 reads out the storage contents of the teaching value memory 2 and operates an arm through an actuator 6. Since the teaching modification of the teaching value is carried out by including not only the deviation of the positions but also the deviation of the speeds like this, the number of modifications can be decreased and a stable convergence result can be obtained.

Abstract: PURPOSE:To easily form a sealing resin layer which is secure and is resistant to peeling by sticking a liquid synthetic resin which is dissolved at the temp. below the decomposition or evaporation temp. onto a coating metallic layer formed on the surface of a base material by executing a thermal spraying treatment of a metal. CONSTITUTION:While the base material 5 of a carbon steel, etc., is moved in an arrow direction, a molten metal 6, such as Al, is thermally sprayed via a thermal spraying nozzle 2 for the metal from a molten metal supplying system 1 onto the surface thereof. This molten metal 6 forms the coating metallic layer 7 of a solidified state when cooled. The molten resin 8 is thermally sprayed via a thermal spraying nozzle 4 for the resin from a molten resin supplying system 3 onto this coating metallic layer 7 and forms the solid sealing resin layer when cooled. The molten resin 8 mentioned above is made into the liquid state by dissolving the synthetic resin at the temp. lower than the decomposition or evaporation temp. The thermal spraying position B is set apart a prescribed distance L from the thermal spraying position A of the metal to prevent the decomposition or solidification thereof. The molten resin 8 sufficiently infilters the spacings among the metallic particles of the coating metallic layer 7 and the resulted sealing resin layer 9 exhibits a high adhesive property and sufficient sealing effect, thereby maintaining the corrosion resistance over a long period of time.

The frequency of the output of the circuit 5 is reduced by half by a 1/2 frequency divider 7. A ring counter 10 operates synchronously with the output of the divider 7 and a set of interphase voltage. The phase sequence of the 3-phase AC power source is detected by a phase sequence detector 15. Then, the output of the counter 10 is automatically switched by the phase sequence of the 3-phase AC power source, thereby associating the outputs of the ring counter and generating a polyphase signal which is synchronized with the 3-phase AC power source.
