Title: Low noise receiver
Inventor: AKAHA HAJIME
IPC: H04B1/10
Filed: 1981-10-20
Abstract: PURPOSE:To improve the noise figure and threshold value at a region having a low reception input, by turning off a switch circuit when a reception electric field is a prescribed value or over, and passing through a signal with a low reception level, without passing through a reception signal in a low noise amplifier. CONSTITUTION:A switch 3 is operated with information from a reception input electric field level monitoring circuit 7 at a region where a reception input level is high, and a signal from an input terminal 1 passes through a circulator 2 and is reflected at the switch 3. Since the signal is not amplified at a low noise amplifier 5 but amplified at a receiver 6 via the circulator 2, the receiver 6 is not saturated and not band-limited with a filter 4, the transmission characteristics are not deteriorated. At a region where the reception level is low, after the reception signal is amplified at an amplifier 5 through the circulator 2, the switch 3 and a BPF4, the signal is amplified at the receiver 6 through the BPF4, the switch 3 and the circulator 2 and the noise figure can remarkably be improved.

IPC: H01L21/677
Filed: 1982-09-28
Abstract: PURPOSE:To correct an unbalance regarding the capability of treatment among various treating devices, and to charge or discharge the wafer stably in response to the capability of treatment at all times by providing a plurality of conveyor belts, a guide forming a conveying-path wall and a drive and providing one free ends of the second and third conveyor belts with fourth and fifth conveyor belts. CONSTITUTION:When the wafer 10 is being conveyed by the forward revolution of the conveyor belt 11 from the treating device A, a sensor 25 detects the reaching of the wafer 10, and the direction of rotation of the belt is determined by a belt-rotation controller regarding a supply to either of the device B or C at a rear stage by a branching section. When the wafer 10 is charged to the treating device B at the rear stage, the belt-rotation controller operated by a detecting signal from the sensor 25 turns forward the belts 12 and 13, and reverses the belt 17. Accordingly, the wafer 10 is moved on the belt 12 and the belt 13 from the belt 11, and charged (carried in) to the device B.

Title: Non-contact feeding mat
Inventor: SHINOZUKA MOTOO
IPC: H02J17/00
Filed: 1992-06-26
Abstract: PURPOSE:To provide a jig pallet which requires no maintenance and which can feed to an equipment to be fed safely with no contact with the equipment. CONSTITUTION:On an upper face of a mat main body 1 constituted of a movable insulator, a groove 2 is formed. Along the groove 2, an induction line 3, a coated litz wire, is installed. A power supply M which feeds a high-frequency sine-wave current is connected to the induction line 3. When pick-up units P1, P2 which are connected to an equipment to be fed are drawn near to the induction line 3 and then the induction line 3 is caused to conduct (ac), an electromotive force is generated in coils of the pick-up units P1, P2. With this electromotive force used as a power supply, power is supplied to the equipment to be fed with no contact with the equipment. Therefore, unlike the conventional method wherein a collector ring and a conduction rail are used, there is no abrasion and so no maintenance is required and an occurance of a spark is prevented. Furthermore, since the induction line 3 is coated, an electric shock is avoided.

Title: Filter leak inspection equipment
Inventor: MORIOKA KOJI
IPC: G01N15/08
Filed: 1997-06-25
Abstract: PROBLEM TO BE SOLVED: To prevent inspection error due to fluctuation in the concentration of a powdery material in an air supply chamber by spraying the powdery material being delivered together with a generating gas, while diluting with a diluting gas, into the air passing through an air supply duct. SOLUTION: The generating means 12B for a mixing means 12 is fed with a generating gas from a first gas supply means 12A and generates a dispersed powdery material P in the generating gas and a diluting means 12C dilutes the powdery material P being delivered together with the generating gas with a diluting gas supplied from a second gas supply means 12A. A spray means D sprays the powdery material P being delivered from the diluting means 12C together with the generating gas into the air passing through an air supply duct 8. Since the powdery material P is diluted the diluting gas by the diluting means 12C, diffusion of the powdery material P mixed into the air passing through the air supply duct 8 is accelerated and the concentration of the powdery material in the air supply chamber 5 can be prevented from being fluctuated.  The first and second gas supply means 12A shares a compressor.

Title: Control device
Inventor: SAKAMOTO HIDEO
IPC: G06F11/30
Filed: 1992-06-02
Abstract: PURPOSE:To obtain high reliability against artificial and systematical illegality by furthermore judging whether a storage element is a normal product or not in a control device for executing the monitoring of runaway by means of a watchdog timer circuit. CONSTITUTION:Immediately after the rising of the voltage of a power supply line VC, a CPU 10 executes an initial processing program and confirms an identification(ID) code stored in a prescribed area of a PROM 12 to judge whether the PROM 12 is a normal product or not. Power supply to the watchdog timer circuit 18 is delayed by the period of a time required for the judgement, so that the misrecognition of runaway can be prevented even if the CPU 10 does not reset the circuit 18. However runaway monitoring by the circuit 18 is executed similarly to a convensional method during the period that the CPU 10 executes processing based upon a control program.

Title: Front body structure for vehicle
Inventor: HIRATA TSUTOMU
IPC: B60D1/04
Filed: 1998-06-16
Abstract: PROBLEM TO BE SOLVED: To increase the degree of freedom of the tuning of the collision performance as the frame unit by reducing the influence which the sub-frame installed on the front frame receives against the initial buckling deformation of the vehicle when the front of the vehicle is collided. SOLUTION: A sub-frame 3 consists of a front edge portion 4, a side edge portion 5 and an engine cross member 6. The forward portion of the sub-frame 3 and left and right front frames 1 are axially attached so that they can rotatively move via tie down hook members 7. When the front frames 1 start buckling deformation at front collision, the tie down hook members 7 are rotatively moved centered on the axially attached portion with a bolt 8a to the front of the vehicle relative to the front frames 1, which makes it difficult for the influence of the buckling deformation to be transmitted to the sub-frame 3. As a result, degree of freedom is increased in staggering the timing of starting the buckling deformation of the front frames 1 and the sub-frame 3.

Abstract: PURPOSE: To easily set the boundary of a specified positional area of a boom arm by disposing, on a carriage, those signal elements which generate barriers extending onto a table laterally relative to the direction of motion of the carriage. CONSTITUTION: Two signal generators 56 indicate a motion area between two limits 57 for a boom 6 interlocked with each other. These limits 57 are optical barriers which are disposed on an upright side plane. A signal receiver 58, which is disposed in the boom 6, receives signals from the signal generator 56 interlocked with the limits 57 when it moves into one or the other limit 57. By this means, a switch of a driving device of the carriage 3 is turned on and, by a control means, the driving device is moved slightly in the direction that the signal receiver 58 is moved when the signals are generated.
