Abstract: PURPOSE:To improve the recording density, by equalizing the gap of a magnetic head to the relative moving direction of a magnetic recording medium. CONSTITUTION:A magnetic head 10 in which length L of a gap G2 is L=(2n+ 1)X(T/2) [T and (n) denote 1 bit length and an integer, respectively] is constituted so that the direction of the gap G2 becomes equal to a relative moving direction 3 of a magnetic tape 2, a track C is magnetized to S-pole and N-pole in accordance with binary bits, 1, 0, and digital recording is executed. Subsequently, a timing signal generating signal group A and a digital data signal group B which are recorded in the track C are read out by the head 10, and are subjected to PLL processing, etc., by which the signal group B is reproduced. According to this constitution, the width of the track C becomes small, and the recording density can be improved.

Title: Combustion controller
Inventor: UGAJIN TOSHIYUKI
IPC: F23N5/24
Filed: 1993-04-20
Abstract: PURPOSE:To facilitate repairing works by a method wherein it is judged that service interruption is generated when the value of DC current is LOW but it is judged that a trouble is generated in a waveform-shaping circuit when the same is HIGH. CONSTITUTION:During heating operation, a DC current, obtained by rectifying a commercial power supply 1, and the voltage of the commercial power supply 1, whose waveform is shaped by a waveform-shaping circuit 11, are inputted into a microcomputer 7 respectively. The microcomputer 7 observes whether a predetermined output of the waveform shaping circuit 11 has not been inputted for more than a predetermined period of time or not. When the predetermined output has not been inputted for more than the predetermined period of time, the microcomputer 7 observes whether the value of voltage of the current is LOW or HIGH. When the value is LOW, the microcomputer Y judges that the voltage of the commercial power supply 1 is not supplied or service interruption is generated but when the same value is HIGH, the microcomputer 7 judges that it is not service interruption and a trouble is generated in the waveform shaping circuit 11. According to this method, repairing works can be facilitated.

Title: Pulse generating circuit
Inventor: OSAWA MASAYUKI
IPC: H02P29/00
Filed: 1995-03-24
Abstract: PURPOSE: To reduce an abrupt speed change and a movement shock, eliminate reaction at the time of conveyance by a pulse motor, and improve operability and shorten an operation time by representing time variation in pulse frequency by a trigonometric function. CONSTITUTION: As the time variation in the frequency of pulses generated by the pulse generating circuit, not the sigmoid characteristic using a conventional quadratic function, but a sigmoid characteristic using a trigonometric function pattern is employed. A circular pulse distribution arithmetic circuit 12 generates trigonometric function components. For example, when the speed is varied by varying the target frequency of output pulses in a cosine function curve shape as the trigonometric function pattern, the acceleration obtained by differentiating the speed varies according to a sine function curve as a similar trigonometric function. Therefore, variation in the acceleration becomes smooth even at maximum acceleration and the movement shock due to abrupt speed variation is reducible.  Further, smooth variation is obtained even at the start point and end point of the acceleration similarly to the sigmoid acceleration system of the conventional quadratic function pattern.

IPC: H01L21/60
Filed: 1986-04-23
Abstract: PURPOSE:To improve junction strength between a copper ball and an electrode and improve reliability of a semiconductor device in which copper wires are employed. CONSTITUTION:Electrodes 3 of a semiconductor device are connected to leads 4 with copper bonding wires 1 and lead out. The electrode films are made of aluminum or aluminum alloy which has hardness 0.6-1.2 times of the hardness of the copper balls 6. With this constitution, as the electrode film is hard, when the ball 6 is bonded on the electrode 3, the film does not come outside the ball 6 and the ball 6 and the electrode 3 can be rubbed against each other sufficiently. Therefore, by removing the oxide films on the ball 6 and the electrode 3, large new surfaces can be obtained and high junction strength can be obtained.

Title: Touch switch circuit
Inventor: INAGAKI KOJI
IPC: H03K17/96
Filed: 1987-04-15
Abstract: PURPOSE:To attain normal switching operation independently of the polarity by connecting two diodes to a thyristor, connecting one diode to one terminal of an AC power supply and connecting it to the other terminal of the AC power via a power generating resistor for a transistor. CONSTITUTION:With a receptacle A connected to a line Mp (not an alive line), when the line Mp goes to an AC positive potential, a minute current flows in a route shown in broken lines, a transistor (TR)1 is turned on and a gate current flows to an SCR1 via a resistor R4 and a diode D2. With a receptable B connected to the line Mp, when the line Mp goes to a positive potential of the AC power, a minute current flows in a route of the receptacle A and a line R through the route of ground human body touch section R7 TR1 R4 R5 R8 R-9. Thus, the TR1 is turned on and a capacitor C2 is charged and a gate current flows to the SCR1 at the next half cycle. Diodes D3, D2 prevent the current from flowing from the line B to the TR1 with the receptacle B at the positive potential thereby enabling the flowing of the minute current.

Abstract: PURPOSE:To realize the reduction of the parity memory capacity by allocating just a single parity bit to plural addresses. CONSTITUTION:A counter CNT performs a count-up action with reception of a clock pulse and supplies the addresses to a data memory DMEM and a parity memory PMEM.

Abstract: PURPOSE:To provide an optimum discriminant function used for the diagnostic rule of a diagnostic system by means of a linear plan method. CONSTITUTION:A positive/negative example separation part 11 divides an inputted diagnostic example 10 into a positive example 12 and a negative example 13.

A negative example conversion part 15 generates a linear limited expression 17 obtained by adding a second variable increasing the constant item to the negative example and encoding the unequal sign. A linear plan execution part 18 sets the total of the first variable and the second variable to be a target function 19, and generates a discrimination function 20 so that the target function 19 becomes a minimum with the limited expressions 16 and 17 against the positive and negative examples as limited conditions. The diagnostic system generates the whole discriminant function by repeatedly using a learning system 1 for plural illnesses.

Abstract: PURPOSE:To use a single spring in lowering a wick for cost reduction by installing a single spring between an actuation plate for transmitting the vertical movement of wick adjusting lever to a wick adjusting shaft. CONSTITUTION:When a wick adjusting lever 115 of a wick adjusting device 100 is pushed down, a wick adjusting shaft 111 is rotated via a fine-adjusting plate 117 and an actuation plate 116, so that a wick 300 is raised to the combustion position via an arm 112.

If a vibration exceeding the safety standard of the oil stove, a tipping portion falls down and the arm of the fire extinguishing lever 118 is raised, so that the latch pin in the latch groove is unlatched and the actuation plate rotates the wick adjusting shaft 111 by means of the tension of a spring 500. As a result, the wick adjusting lever 115 rises and the wick 300 is lowered to the fire extinguishing position.
