Abstract: PROBLEM TO BE SOLVED: To enable testing inside a chip and to shorten testing time by providing the surface of the same chip as the memory with a means which writes a selected pattern into the memory cell array using selected word lines and a means which compares the data read out by the reading cycles with the above pattern to output test results. SOLUTION: A test circuit 7 of this memory provided with fast testing function includes a selecting means which selects and outputs a fixed pattern or an arbitrary pattern from a fixed pattern storing means and an arbitrary pattern generating means. A testing data writing circuit 5 writes the pattern from the testing circuit 7 to a selected row of the memory cell array 1. A test data checking circuit 6 compares the pattern from the testing circuit 7 with the read data from the memory cell array 1. When testing is unfinished, the counter is controlled so as to count up the row address and otherwise the results of testing are outputted.

Abstract: PURPOSE:To prevent a laser beam from finding its way into a user due to the erroneous action of a laser beam source by using a link mechanism for allowing a nip roller to come in contact with and leave an exposure drum, installing a shutter along with a link which constitutes the link mechanism and activating the shutter to enter and clear out of a laser beam optical path by drive of the link mechanism. CONSTITUTION:A shutter 78 is arranged so that at least, a pair of links 84a whose link mechanisms 76a arranged at both ends of the nip rollers 72, 74 correspond to each other, are connected together, using the link mechanism 76a which allows the nip rollers 72, 74 to come in contact with and leave an exposure drum 70. The shutter 78 is parked from the optical path of a laser beam L when the nip rollers 72, 74 come in contact with the exposure drum 70 by action of the link mechanism 76a. Further, the shutter 78 enters the optical path of the laser beam L when the nip rollers 72, 74 have left the exposure drum 70. Consequently, it is possible to prevent the laser beam from being emitted into the eye of a user, even if the laser beam source for recording an image is erroneously activated.

Title: Capacitance type acceleration sensor
Inventor: HANZAWA KEIJI
IPC: G01P21/00
Filed: 1992-08-27
Abstract: PURPOSE:To initiate fail-safe function and improve reliability by using a sensor in state where a movable electrode is initially displaced under the application of static electricity. CONSTITUTION:An acceleration detecting element 18 is constituted of a silicon beam 5, a movable electrode 6 and fixed electrodes 7 and 8. When a power supply is turned on, AC voltage VS1 for detecting capacity is applied to diagnostic DC voltage VG via an adder 23, thereby applying static electricity between the fixed electrode 7 and the movable electrode 6. As a result, the movable electrode 6 is displaced, and capacitance C1 and C2 across the electrodes changes. In this way, the movable electrode 6 of the detecting element 18 is forcibly displaced, and this displacement state is used as an initial value (value without acceleration) to detect the displacement of the electrode 6 to be applied with acceleration on the basis of a difference between the capacitance C1 and C2. The application of the self-diagnostic voltage VG at all times means that the sensor is always caused to operate under the application of acceleration. According to this construction, a sensor failure (such as degraded performance) can be easily and accurately diagnosed.

The CPU 1 compares the request movement quantity steps with the actual operation pulse numbers and calculates correction movement quantity according to their difference when they do not match each other. High-precision driving control can be performed through the correction.

CONSTITUTION:The resonance circuit of a sensor device 30 installed at the outside of a building has the resonance frequency in response to the outside air temperature and is resonated at its resonance frequency. The resonance circuit is resonated by the monitoring frequency signal received by the resonance circuit via an antenna 31 on condition that the frequency of the monitoring frequency signal sent by the signal generation section 21 of a main device 20 is the same as the resonance frequency of the resonance circuit of the device 30. An echo is received by a wireless antenna 23 via the electromagnetic coupling by the resonance current. The echo is inputted to the detection section 22 of the device 20a, the detection section 22 can detect the resonance frequency of the resonance circuit at that time, i.e., the outside air temperature corresponding to the resonance frequency, from the frequency of the monitoring frequency signal generating this echo, and the outside air temperature can be displayed at an outside air temperature display section 26 in the building.

IPC: H03F3/217
Filed: 1994-08-30
Abstract: PURPOSE: To make a power amplifier small in size and low in power consumption by providing a boosting type pulse transformer between a power amplification stage and a demodulation stage and selecting a high switching frequency. CONSTITUTION: A PWM modulation is performed for an input audio signal in a square wave generator 11, a saw tooth wave generator 12 and a PWM generator 13, and a power amplification is performed for a PWM modulation signal at a switching device 15 to which incorporated power supply voltage +12V is supplied in a switching timing signal generation part 14 and the signal becomes a signal F. This signal F is boosted by a pulse transformer 17 where a winding is 1:2, etc., and becomes equivalent to the matter in which the power supply voltage substantially becomes twice or 24V. Further, when the frequency of the device 15 is increased, a high output and high efficiency are produced because a DC-DC converter is not used and this amplifier is made small in size and low in power consumption and is suitable for an on-vehicle type.

Title: Controller capable of connecting to magnetic recording and reproducing device
Inventor: MINOURA NOBUO
IPC: G11B27/10
Filed: 1985-10-16
Abstract: PURPOSE:To prevent the generation of confusion even in case the operating switch of a magnetic recording/reproducing device is depressed, by invalidating an electrical connection state between an operating switch and a head controller when the 1st and 2nd connecting elements are connected to each other. CONSTITUTION:Both Fwd and Rev output terminals of a controller 50 are usually kept at L levels. While the output of a NAND circuit 61 is kept at an H level with a transistor TR 62 kept on. Therefore the scan pulse signal of an H level is sent to the ground via a socket 62, the terminal H of a plug 59 and the TR 62 even though a controller 40 delivers said scan pulse to a terminal H for the key scan purpose. Thus no scan pulse of an H level emerges at the input terminals A1 and A2 of the controller 40 despite the depression of a forward switch 16 or a reverse switch 17. This produces no confusion to the random access processing.

Subsequently, the auxiliary patterns 5a, 5b, 5c are removed selectively leaving only main patterns 4a, 4b on the layer 3 to be machined.

IPC: B24B37/10
Filed: 1997-08-26
Abstract: PROBLEM TO BE SOLVED: To minimize alignment shifts during transfer of photo mask pattern, when the surface of a semiconductor wafer is chemically and mechanically polished by equalizing the rotational speed of a polishing table with the rotational speed of a wafer carrier. SOLUTION: A wafer carrier presses a fixed wafer using a vacuum chuck or the like against a polishing table with a polishing pad placed on its surface, and holds the wafer there. The polishing table and the wafer carrier are turned together during polishing. Polishing agent (slurry) having specified chemical properties is applied to the contact plane between the wafer and the polishing pad. Further, an ammeter is placed between a motor for turning the wafer carrier and a power supply. At this time, the rotational speed of the polishing table is equalized with the rotational speed of the wafer carrier. As a result, a point on the wafer is polished regardless of its position on the wafer, while homogeneity and uniformity are maintained.
