Title: Humidity sensor
Inventor: SAMEJIMA SHIYUNEI
IPC: G01N5/02
Filed: 1982-05-11
Abstract: PURPOSE:To obtain a humidity sensor with a long life, limited aging, a better exchangeability and a high resolution by connecting one end of a humidity sensitive member to one of two piezo-electric vibrators and the other end thereof to the other piezoelectric vibrator so as to measure the humidity from output of a circuit adapted to determine the difference in the resonance frequency. CONSTITUTION:Crystal resonators 3 and 4 shall be AT cut crystal resonators of the same kind. The temperature characteristic and aging property are roughly equal and the resonance frequency is set almost equal by at f0 when the humidity is at H0%. As the humidity varies from H0% to H%, the resonance frequency of the crystal resonators 3 and 4 changes. The difference DELTAf in the change of the resonance frequency with respect to the change in the humidity is outputted from a mixer 11a. The crystal resonators 3 and 4 are so set that the resonance frequency of one thereof increases but that thereof decrease due to variation in the tension of hair 8. Therefore, DELTAf gives a large value with the respect to the change in the humidity. As compared to the case of using only one crystal resonator, this enables the humidity measurement with a higher accuracy to obtain the humidity H%f from DELTAf. As humidity information can be obtained in conversion to change in the resonance frequency of the crystal resonator, direct digital processing is possible without the use of an A/D converter.

Title: Dial selection signal system
Inventor: KIMURA SHIGEKATSU
IPC: H04Q3/54
Filed: 1983-05-04
Abstract: PURPOSE:To facilitate the dialing operation of a calling subscriber on wrong dialing by performing redialing based upon the phase of a pause tone sent out of a switching network when an error of a dial selection signal is detected so as the calling subscriber is not required to hook the receiver. CONSTITUTION:The switching network N connects the telephone set T of the calling subscriber to, for example, the dial number receiver of a switchboard by origination connection. If the calling subscriber presses keys ''3'' and ''2'' at the same time by mistake when pressing ''3'' in 1234 during the dialing of a remote telephone number (0422 59 1234), a predetermined code key (#) for cancellation C, and then the code (#) for cancellation C is detected in the switching network N, and the phase of redialing tone transmission is entered to send out a dial tone to the telephone set T of the calling subscriber. The calling subscriber inputs the remote telephone number without hooking the receiver. Consequently, the dialing operation of the calling subscriber on wrong dialing is facilitated.

Title: Wire cut electric discharge machine
Inventor: TANAKA YUTAKA
IPC: B23H7/06
Filed: 1979-06-22
Abstract: PURPOSE: To conduct electric discharge machining while keeping interelectrode voltage constant and enable to conduct high-precision machining by a method wherein the relative feed speed of an electrode and a work is controlled based on the integrated value of the error voltage which is the difference between a reference voltage and the interelectrode voltage, i.e. the voltage between a wire electrode and the work.  
     CONSTITUTION: The error voltage -Ee between the interelectrode voltage Eg detected at a comparator 46 and a reference voltage Eo is integrated by an integrator 56, to obtain a table feed speed signal F. Due to the integration action of the error voltage, the steady gain of the control system becomes infinite and the error voltage -Ee converges absolutely to zero. Therefore, even if the machining speed at the lower surface of the work 10 is reduced owing to the transfer to taper machining on a curved portion and the machining amount per unit time is reduced, the excess energy of a power source device 32 will not increase the width of the groove being machined.

CONSTITUTION:An insulating layer 2 is formed into the shape of a film on an insulating substrate 1. Two trench parts 3 are formed on the above film and the 1st amorphous silicon layer 4 is laminated so that the film may have a film thickness which is thinner than that of the insulating film 2. Then the 1st amorphous silicon layer 4 is removed together with a part of the surface of the insulating layer 2 and the 2nd amorphous silicon layer 5 is laminated on both the insulating layer 2 and the 1st amorphous silicon layer 4. Both the 1st amorphous silicon layer 4 and 2nd amorphous silicon layer 5 are converted into a crystalline layer 7 by irradiating laser beams. Then a transistor having the above crystalline silicon layer 7 as a channel is formed. Stepped forms in channel regions of the silicon layers 4 and 5 are thus removed and a transistor which is superior in efficiency and is resistant to peeling off is formed.

IPC: H05K3/28
Filed: 1992-02-29
Abstract: PURPOSE:To make a circuit board without pinholes, compact and light in weight, by applying a thin film on a hybrid integrated circuit board through dip coating. CONSTITUTION:The adhesive power of a coating material 1 functions between a circuit board 5 and wall faces opposing each other through a clearance slightly wider than the overall thickness including an electronic part 6 on the circuit board 5 in a coating material tank 2 when the circuit board 5 is immersed in a coating material. When the circuit board 5 is lifted up, shearing force is applied to the coating material 1 in the slight clearance, and a film adhered on the circuit board 5 is peeled off. Thus a circuit board with thin film can be manufactured by dip coating the circuit board using conventional means regarding viscosity of the coating material, lifting speed of the circuit base, and the like.
