Title: Schottky junction diode
Inventor: MATSUMOTO SATOSHI
IPC: H01L29/872
Filed: 1998-01-16
Abstract: PROBLEM TO BE SOLVED: To avoid flowing unwanted leak currents to a Schottky diode and load, by using a metal having a comparatively low work function for an anode metal electrode and a metal having a higher work function than the anode metal electrode for a current blocking metal electrode. SOLUTION: A current blocking metal electrode 16 is made of a metal having a comparatively low work function. Hence, when a signal from a signal source takes '0' in binary notation, a depletion layer expanding from an input film 7 to the island part 3 can be expanded enough to run across the island part 3, if the cross sectional area of an island part 3 is widened to flow a high current to a load through a Schottky junction diode. When the signal from the signal source takes '0' in binary notation, hence unwanted leak current cannot be flowed to the Schottky diode and load.

Title: Method and device for drying
Inventor: SHIMAI FUTOSHI
IPC: H01L21/304
Filed: 1994-02-17
Abstract: PURPOSE:To prevent dust from adhering again to a platelike work so as not to cause damage to it by a method wherein a fried gas is made to flow down along the surface of the work and discharged out below. CONSTITUTION:After a glass substrate W is cleaned, it is set on a chuck 26 inside a case 21 of a drying device 20 by a transfer device. Then, as the glass substrate W is rotated by a spinner 25, dried gas of air or nitrogen jetted out from a nozzle 33 is made to flow down from above over the surface of the glass substrate W. The died gas is made to flow along the surface of the glass substrate W to dry up residual cleaning water left on the surface of the glass substrate W and discharged out through an exhaust vent 34 provided below. By this setup, a glass substrate W can be dried out in a short time even under a normal pressure. Dust is prevented from adhering again to a platelike work, so that dust is restrained from causing damage to semiconductor device if the platelike work is a semiconductor substrate.

Filed: 1990-01-31
Abstract: PURPOSE:To quicken a recording action and to shorten a recording time by detecting a signal recorded on a recording medium by a 1st optical means by using a 2nd optical means and performing verification. CONSTITUTION:When the recording signal is inputted in an optical disk 10 set at a specified position, encoding and error processing are performed to the recording signal by a signal processing circuit so as to divide to information in sector unit. While the optical disk 10 which rotates at a constant linear velocity is irradiated by a light beam for over-write 3a, an optical head 1 is moved from an inner periphery side to an outer periphery side to retrieve a sector and a track corresponding to a recording address and successively execute the over-write. At such a time, the readout of the recording signal by a light beam for verification 5a is performed to the adjacent track which is one track inside, and the recording signal previously detected is compared with the record ing signal recorded by the beam 3a. When they do not coincide, rerecording in an error sector or recording in an alternative sector is performed, and when they coincide with each other, the recording action to the next recording address is executed.

Title: Differential detection circuit
Inventor: MIZUIDE YASUO
IPC: H03F3/45
Filed: 1982-02-12
Abstract: PURPOSE:To obtain a differential detection circuit having characteristics not changed while a current value of a current source is kept for a prescribed value, by sharing the current of the current source to one side completely depending on the polarity of an input voltage at the moment when the current of the current source starts flowing from[0]. CONSTITUTION:As paths of current flowing to the circuit, there are the 1st path of resistor R1, base and emitter of a transistor (TR)4, and emitter of a TR2, and the 2nd path of resistor R2, base and emitter of a TR3, and emitter of a TR1. When a signal IN1 is lower than a signal IN2, the current flowing to the 2nd path is increased. This current is given to the base of the TR3, the resistance of the TR3 is lowered and the current of the collector is increased, then the base current of the TR4 is decreased to cut off the TR4, TR2 through the assistance of the difference of currents. The input voltage is inverted in this state, and even if IN1>IN2, this state is kept when a certain degree of the I1 flows.

Abstract: PURPOSE:To control the deterioration of wow and flutter by outputting an error signal through a notch filter, which eliminates frequency components of a head switching pulse, when a tracking servo system is stabilized and eliminateing the variance of the error signal which is generated at every head switching time. CONSTITUTION:When the tracking servo system is set to the servo lock state, a lock detection signal PH outputted from a holding circuit 25 goes to the low level because an error signal TE outputted from a differential amplifier 20 has a certain voltage. Then, a changeover switch 28 of a switching circuit 26 is switched to the side of a terminal (b), and an error signal TN obtained by allowing an error signal TE' from a changeover switch 21 to pass through a notch filter 27 is outputted as an error signal TEN to the tracking servo system to perform tracking control. That is, when the servo system is set to the lock state, frequency components of the switching pulse are eliminated from the error signal TE' by the notch filter 27 for the purpose of preventing frequency components of the switching pulse corresponding to a video head switching period from having influences upon wow and flutter.
