Title: Vehicle detector by high-sensitivity earth magnetism sensor
Inventor: MACHIDA AKIRA
IPC: G01R33/02
Filed: 1997-11-10
Abstract: PROBLEM TO BE SOLVED: To securely detect whether or not a vehicle is present without being affected by withered leaves, dust, fallen snow, rain by detecting the difference between the earth magnetism when a vehicle is present in a specific parking space and that when not by using a microminiature high-sensitivity density earth magnetism sensor and detecting whether or not there is the vehicle. SOLUTION: In the space occupied by a vehicle parked in the parking space, a vehicle detector 2 is installed on the ground. As the installation position of the vehicle detector 2, a place wherein variation of the earth magnetism can distinctively be detected from whether or not there is the vehicle is previously selected. The detection signal from this vehicle detector 2 is inputted to a signal processing circuit 4 through a signal line 3, processed, and sent out to a display device and a monitor device. Namely, the earth magnetism signal detected by the subminiature high-sensitivity earth magnetism sensor 5 of the vehicle detector 2 is amplified by an amplifier 6, processed by a comparator 7, and inputted to a digital output circuit 8, which inputs the digitized signal to a signal processor 4 through the signal line 3.

Title: Substrate for semiconductor device and manufacture thereof
Inventor: SANADA MASAYUKI
IPC: H01L21/304
Filed: 1997-10-09
Abstract: PROBLEM TO BE SOLVED: To achieve a haze level, after a high temperature thermal treatment, that equals to that of the Czochralski (ML polished) wafer which is not subjected to a high temperature thermal treatment, by tilting a main flat surface of a silicon single crystal at an angle within a specific range relative to a specific surface, and tilting the other specific surfaces at an angle within other specific range. SOLUTION: A silicon single crystal is grown by the Czochralski process (CZ) by pulling along the direction of <100> and cut so that the main flat surface thereof is tilted at an OFF angle of 0.05-0.08 deg. in the direction of <01-1> or <0-11>, and 0.02-0.06 deg. in the direction of <0-1-1> or <011>. Thus, when the tilt angles of the main flat surface are set within four rectangular frames, there is little variation in haze level prior to and after hydrogen annealing, and no color haze is recognized on visual observation under oblique light, thus ensuring good surface state. Accordingly, the haze level of this silicon after high temperature thermal treatment can be at the same level as that of a CZ (ML polished) wafer which is not subjected to high temperature thermal treatment.

Title: Motor controller for electric automobile
Inventor: FUKUYAMA YUICHI
IPC: G10K11/178
Filed: 1993-12-22
Abstract: PURPOSE:To reduce noise over a wide range of motor current by correcting the current variation width for noise cancellation in reverse proportional to the average value of motor current. CONSTITUTION:The gain of an amplifier 4a is corrected by a correcting unit 5 to output a current variation width ip-p for noise cancellation in reverse proportional to the magnitude (im) of motor current delivered from a torque current command generating section 2. The corrected current value is added to an accelerator signal 1 and an average motor current (im) generated from the torque current command generating section 2 and then compared, at a comparator 7, with a carrier generated from a carrier generator 6. Output from the comparator 7 is fed to a gate signal generator 8 which switches the current switching means, i.e., MOSFETs 1-4, for a drive motor 9 thus controlling the torque or noise of the motor 9. This constitution allows constant and appropriate noise reduction over a wide range of motor current (torque).

Abstract: PURPOSE:To produce a large space between a thermal head and a platen roller to facilitate a thermal head cleaning operation and a printing paper jam removing operation by a method wherein a load member is divided into two parts and supported by a shaft, and one of the load member parts holding a thermal head is made rotatable. CONSTITUTION:In a thermal head mechanism, a knob 12 of a holder 3 is slid in an arrow direction in a neutral state other than a printing action state of a thermal head 1, whereby an engaging claw 3a of the holder 3 is disconnected from a square hole 2a of a load member 2, and the load member 2 is made rotatable about a shaft 5 as a fulcrum. Therefore, the thermal head 1 held by the load member 2 can be moved upward to be spaced a large gap from a platen roller. As a result, by inserting a hand between the thermal head 1 and the platen roller, a user can easily conduct a thermal head cleaning operation and a printing paper jam removing operation. After the thermal head is cleaned or a jam is removed, the load member 2 is moved downward, whereby the engaging claw 3a again engages with the square hole 2a to connect the load member 2 with the holder 3 to perform a printing action.

Filed: 1990-11-26
Abstract: PURPOSE:To reduce an electric field to be applied to a gate oxide film of a P-channel MOS transistor by applying an intermediate voltage of a VCC and a GND level to a back gate electrode of the transistor in a charge pump. CONSTITUTION:Vin3 is applied to the back gate electrodes of P-channel MOS transistors 2, 3, 5 and 6. When an input signal 2 is continuously applied as a Vin2 to a node N4 as a Vin1, the output voltage VBB of a board bias generator becomes (Vth-VCC). When the Vin1 becomes the VCC and the Vin2 becomes a GND level in this state, a node N2 becomes the GND level and the node N4 becomes -XCC. On the other hand, a voltage of Vin3 is applied to the back gate of the transistor 3, a voltage of 1/2VCC-(--VCC)=3/2VCC is applied to a gate oxide film of the transistor 3 in the case of Vin3=1/2VCC. Thus, a storing electric field is not applied to the gate oxide film of the MOS transistor.

Abstract: PURPOSE:To improve recording quality by making bleeding of ink adequate by a method wherein a porous film consisting of water expellent fluororesin is used. CONSTITUTION:An ink feed component, i.e. a roll 3 will suffice for the purpose when it can be impregnated by conductive ink, and sponge is used therefor herein. An insulating porous film of, for example, 30-100 mum thickness consisting of fluororesin is used as a film for screen (mesh) 1. A porous sheet or film a surface of which is made insulating by covering it with fluororesin may be used. A metallic electrode 4 is buried in a platen 5. A plurality of electrodes 4 are arranged in a line direction. By impressing voltage selectively to this electrode, ink sticks by being attracted onto recording paper 2 corresponding to a position of the electrode 4 to which voltage is impressed and recording by a dot is performed. Water-color conductive ink is used as ink. Since such a porous film consisting of water expellent fluororesin is used, when voltage is impressed between the ink feed component and the electrode, ink bleeds adequately through a hole of the porous film, and printing of mold resolution is obtained.
