Title: Alarm device
Inventor: OKAMOTO NOBUHISA
IPC: G08B23/00
Filed: 1992-03-06
Abstract: PURPOSE:To give an effective alarm to a specific alarmed object person. CONSTITUTION:A sensor 1 is a set of various sensors which detect reference quantities of alarm generation and an alarm sound generation judgement part 2 makes an ON/OFF judgement for an alarm sound according to the reference quantities from the sensor 1 and outputs an alarm sound ON/OFF signal. An alarm original sound generation part 3 controls the output and stop of an alarm original sound according to the alarm sound ON/OFF signal from the alarm sound generation judgement part 2. Further, a sound image control part 4 performs signal processing such as digital filtering wherein 'head transfer function' is simulated for the alarm original sound from the alarm original sound generation part 3 and generates the alarm sound which invades an object human individual space to be alarmed, thereby stimulating only a driver.

Title: Piezoelectric oscillator
Inventor: SATO TOMIO
IPC: H03B5/32
Filed: 1999-02-26
Abstract: PROBLEM TO BE SOLVED: To obtain an oscillator which is superior in noise characteristics and aging characteristics by supplying the feedback current from a rectifying means to the base of a transistor for oscillation so that the operation point comes close to a saturation area when the oscillation output level becomes large and moves away from the saturation area when small. SOLUTION: The feedback current from the rectifying means is supplied to the base of the transistor for oscillation so that the operation point comes close to the saturation area when the oscillation output level large and moves away from the saturation area when small. This oscillator has its crystal vibrator 2 connected to the base of the transistor 3. For example, when the level of an exciting current increases, the operation point of the transistor 3 is preset nearby the saturation area so that part of a signal reaches the saturation area, and then as the base-collector voltage of the transistor 3 drops, the operation point of the transistor 3 comes close to the saturation level, so an excitation level drops.

Title: Method and device for transferring wafer
Inventor: TAKAYANAGI TADASHI
IPC: B65G47/91
Filed: 1996-03-06
Abstract: PROBLEM TO BE SOLVED: To reduce with certainty the suction error of a wafer even when the direction of the surface of wafer to be transferred is somewhat irregular. SOLUTION: An arm, which, is inserted into a container to perform a wafer transfer operation, is slowly moved to the prescribed position in the state that the sucking surface is directed to the wafer to be taken out. If the suction of the wafer is not confirmed (S1 to S3) even when the arm is moved in maximum permissible distance Xmax , the microscopic movement directed to the wafer from the prescribed position (original point) is repeated until the suction of the wafer is confirmed while the direction of sucking surface of the arm is rotated at the prescribed angle θ1 and θ2 to the left-right and up-down directions in the range of maximum angle for one direction.

Title: Voltage controlled oscillator
Inventor: FUKUI HIROKAZU
IPC: H03K3/0231
Filed: 1985-03-14
Abstract: PURPOSE:To simplify the circuit and to stabilize the oscillation by providing a shift circuit shifting a terminal voltage of a capacitor for charge/discharge to a high and a low level. CONSTITUTION:When a switch 51 is turned on and a switch 52 is turned off, the terminal voltage across a capacitor 56 rises gradually. When the voltage exceeds a reference value, the terminal voltage rises rapidly by a shift circuit 54, and then the switches 51, 52 are changed over. Thus, the discharge of the capacitor 56 is started via the switch 52 and the terminal voltage descends gradually. When the value goes down lower than a reference value, the terminal voltage falls down rapidly by the shift circuit 55, the switches 51, 52 are changed over again and the capacitor 56 is charged again. The operation above is repeated. Since one reference value is enough, the circuit is simplified and the oscillation is stabilized.

Title: Production of optical fiber preform soot
Inventor: KIMURA KATSUHISA
IPC: C03B37/018

Abstract: PURPOSE:To obtain the titled preform soot having a constant diameter over the whole length, by using a laser beam, measuring and sensing the outside diameter of a preform at a given position and controlling the rising speed of a seed rod in sooting the outer peripheral surface of the seed rod with a porous preform. CONSTITUTION:A seed rod 2 is raised while being rotated at a given speed and a raw material for a porous preform 5 is fed through a burner 3 and flame 4 into a reaction vessel 1 to soot the outer peripheral surface of the seed rod 2 and produce the aimed preform 5 so as to provide a given thickness while raising the seed rod 2 by a distance (L). On the other hand, a laser receptor 7 is constituted so as to pass a laser beam 8 emitted from an laser emitter 6 through a point (P1) on the outer peripheral surface of the preform 5 during sooting in an ideal state and incident on the laser receptor 7 and measure the outside diameter. If the growth of the preform 5 is delayed by fluctuation of the feed rate of the raw material for the preform 5, the decreased measured outside diameter is detected to reduce the rising speed of the seed rod 2. If the measured outside diameter is increased, it is detected to increase the rising speed and afford the aimed preform 5 having a constant outside diameter for optical fibers.
