Title: Vass code header detecting circuit and magnetic recording and reproducing device
Inventor: NAGASAWA MAKOTO
IPC: G11B15/087
Filed: 1996-04-09
Abstract: PROBLEM TO BE SOLVED: To stably detect the header even when an error is generated to some extent in discriminating a duty of a reproducing control signal. SOLUTION: The duty of the reproducing control signal shaped in waveform by a waveform shaping circuit 1 is discriminated by a duty discriminating circuit 2, arc its result is held by a shift register 3. A value of an analog voltage obtained by converting the sum of values of outputs Q2-Q10 of the shift register 3 by a D/A converter 7 is compared with a reference voltage E1 by a comparator 8, and when the value of Q2-Q10 is 1 as >=8 bits, 1 is outputted as a result of comparison.  In order to obtain an AND condition of an output value of an NOR circuit 5 for taking NOR of output values of Q1 and Q11 of the shift register 3 and an output value of the comparator 8 by an AND circuit 6, even when the most significant bit and the least significant bit are both 0 as a result of the duty discrimination, and an error is generated between them to some extent to be 1 as >=8 bits, 1 is outputted from the AND circuit 6 to enable the VASS code header to be detected, and a header signal is outputted from a D-type flip-flop 9.

IPC: F02P5/153
Filed: 1985-04-24
Abstract: PURPOSE:To provide an internal-combustion engine having high efficiency, by a method wherein torque is controlled to a maximum value under a state in that no knock occurs. CONSTITUTION:A CPU 12 inputs signals from various sensors, e.g., an inner pressure detecting device 30, a crank angle sensor 40, a load sensor 50, through an input output interface circuit 20. Based on the signals, an ignition timing is calculated according to a program stored in a ROM 14, and an ignition signal IGN is outputted through the input output interface circuit 20. By means of the ignition signal IGN, a power transistor 74 is driven and an ignition current is generated to the secondary coil of an ignition coil 76. An igniton timing is controlled so that a crank angle (an angle from a top dead centre), at which a pressure in a cylinder right before production of knock shows a peak, is stored, and in following crank angles, a crank angle, at which the pressure in the cylinder indicates a peak, is adjusted to a crank angle stored.

Title: Substrate processor
Inventor: MATSUI HISAAKI
IPC: H01L21/027
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To provide a substrate processor capable of preventing the contamination of a substrate by particles. SOLUTION: In this substrate processor, a shutter member 27 is elevated when an elevating/lowering block 24 is elevated and a cam follower 36 attached to a swing block 29 is abutted to a stopper 37, when the shutter member 27 faces a substrate passing port 12. Thereafter, when the elevating/lowering block 24 is further elevated, since the elevation of the shutter member 27 is controlled by the stopper 37, upward force acting on the shutter member 27 is converted into a force of turning the shutter member 27 to the side of a processing chamber 1 by a linking mechanism 26. As a result, the shutter member 27 is displaced to the side of the processing chamber 1, and the shutter member 27 is pressed to an O-ring 14 which is disposed at the peripheral edge of the substrate passing port 12. Thus, since the cam follower 36 is abutted to the stopper 37 provided below the substrate passing port 12, even if the particles are generated by the abutting, the possibility of propping the particles onto the substrate passing through the substrate which passes through the port 12 is eliminated.

Title: Abnormality detecting method for vehicle speed sensor
Inventor: ASAKURA MASAHIKO
IPC: G01M15/04
Filed: 1985-04-23
Abstract: PURPOSE:To detect easily the abnormality of a sensor by detecting a fact that a vehicle speed measured by the sensor is below a prescribed value, a power transmission system is formed and also an operation parameter indicates a running state. CONSTITUTION:First of all, whether the vehicle speed is below the prescribed speed or not is discriminated. If it is below, it is considered that a vehicle is not in a running state from the output of the vehicle speed sensor 16, therefore, whether a neutral switch 18 is on or not is discriminated. When the switch is off, the shift lever of a speed change gear is in an in-gear state, therefore, whether a clutch switch 17 is on or not is discriminated. If the switch 17 is off, a power transmission system is formed since the clutch is engaged. Subsequently, whether the revolving speed of an engine exceeds a prescribed revolving speed or not is discriminated. Also, whether an absolute pressure exceeds a prescribed pressure or not is discriminated. If it is above or equal, the vehicle is in a running state, therefore, it is decided that the sensor 16 is abnormal and if this abnormality is continued exceeding a prescribed time, an alarm lamp 34 is lighted.

IPC: B41J2/335
Filed: 1986-04-15
Abstract: PURPOSE:To prevent occurrence of remnants when performing the etching by forming a ceramic layer on a metal substrate then applying an electrode material onto said film thereafter removing the unnecessary portion from the electrode material layer. CONSTITUTION:A recording head substrate is manufactured such that a plasma spraying of ceramics is applied onto a metal plate 1 at first to form a ceramics insulation layer 2 then a plasma spraying of an electrode material, i.e. tungsten, is applied onto said ceramics layer to form an electrode material layer 3. In the plasma spraying, a plasma is ejected through a thin nozzle to form a plasma jet to which a powder material is blown in so as to be fused and flown then adhered and accumulated onto the surface of the substrate thus forming a film. A material having high melting point such as tungsten is applied without requiring a binder nor causing the intrusion of SiO2 from the ceramic layer thus forming the electrode material layer. Consequently, no remnants are produced when an electrode etching is performed.

Abstract: PURPOSE:To prevent elements of a control circuit from being damaged by static electricity which is generated by dust being sucked and transmitted to the control circuit for an electric blower, by a method wherein a conductive resin member with high impedance connects between printed patterns for the control circuit and power supply. CONSTITUTION:A conductive resin member 31 with high impedance for discharging static electricity connects between printed patterns 25a for power supply and printed patterns 25b for a control circuit. The conductive resin member 31 is made of paint or tape. When a paint-type conductive resin is used, it is painted between the patterns 25a and 25b, and fixed on a main control circuit board 9. On the other hand, when a tape-type conductive resin is used, it is stuck between them and fixed on the board 9. Static electricity is generated by friction between dust and a connecting pipe and hose. Since this static electricity is transmitted through steel wires 13 to the control circuit on the main body side of a main control circuit board, and spontaneously discharged to the earth through the conductive resin member 31 and a power supply line, elements 28 of the control circuit are prevented from being damaged.
