Title: Thin film magnetic head and its production
Inventor: ORIHARA HIDEJI
IPC: G11B5/31
Filed: 1985-03-26
Abstract: PURPOSE:To improve the accuracy of life dimensions by providing a reference groove as the reference of life dimensions by an optical means. CONSTITUTION:A reference groove 9 is formed across a nonmagnetic insulator 6 and a magnetic material substrate 2 in the boundary part between a groove part 5, where the nonmagnetic insulator 6 is packed, and the magnetic material substrate 2 in the direction of a magnetic head front end 8 by an optical means such as photolithography or the like, and a nonmagnetic material or a conductive material is packed in the reference groove 9. The reference groove 9 as the reference of life dimensions and a mark 12 as the standard for polishing work of the magnetic head front end surface 8 are formed together by the optical means, and the positioning accuracy of them is improved. The magnetic head front end surface 8 is polished while seeing the mark 12 to attain high- accuracy life dimensions H. Since the reference groove 9 is formed simultaneously with formation of a coil groove 7, the production process is simplified.

Title: Phase adjusting circuit of pulse signal
Inventor: OOTA MICHIHIKO
IPC: H03K5/13
Filed: 1982-04-13
Abstract: PURPOSE:To change delay time continuously and precisely, by inputting the output of a time constant circuit to the base of a transistor (TR) of which collector is earthed directly. CONSTITUTION:A pulse signal inputted from an input signal terminal 10 is delayed at the time up to reference voltage (VREF) by the time constant circuit consisting of a resistor 11 and a capacitor 12 and the delayed signal is applied to the base of the TR13. When the base voltage exceeds the reference voltage applied to the base of a TR14, switching operation is actuated. Consequently, a current flows between the collector and emitter of the TR13, and the current flowing into the TR14 is interrupted, and a pulse signal is outputted from an output terminal 16. Being directly earthed, the collector of the TR13 is not influenced by the base voltage. In addition, optional delay time can be smoothly set up by changing the capacity of the capacitor 12.

Abstract: PURPOSE: To restrain the vibration of a wrapper roller by a method wherein a pressure increase, generated in a pressurizing side of a hydraulic cylinder providing a pushing force to the wrapper roller when a stepped portion of a strip is interferred with the wrapper roller, is maintained in a high degree.  
     CONSTITUTION: A pilot check valve 13, a chock valve 19, a relief valve 21 and an intermediate cylinder 11 are connected to a head side of a hydraulic cylinder 6 to oscillate a wrapper frame 3 having a wrapper roller 2 while the intermediate cylinder 11 is connected to an accumulator 12 and a pump 18 in series. A discharging side of the relief valve 21 is connected to a rod side circuit of the cylinder 6. The check valve 13 is connected to a 4-ways valve 15 through a parallel circuit comprising a reducing valve 14 and a check valve 20. When a stepped portion of a strip 5 is collided with the wrapper roller 2, a pressure in the head side of the cylinder 6 is increased, but an impact force upon the collision may be absorbed by a rightward displacement of a piston in the intermediate cylinder 11.

Title: Privacy call system
Inventor: KITO KAZUAKI
IPC: H04L9/16
Filed: 1989-03-14
Abstract: PURPOSE:To prevent interception by other slave station and a third party by scrambling data with a different scramble pattern signal for each time slot of each slave station. CONSTITUTION:A multiplex circuit 1 applies time division multiplex to data D1-Dn of each slave station, constitutes the data into an information frame and the result is inputted to an exclusive OR gate 5, in which the data from each slave station is scrambled with a scramble pattern signal generated from a scramble pattern signal generating circuit 2 and the resulting signal is outputted. In this case, the data of each slave station is scrambled by using a scramble pattern signal different from each slave station. Thus, even when other slave station than its own station or a third party intercepts the data, the decoding is made difficult and the intercept of the data is prevented.

Title: Method for etching electrode foil for aluminium electrolytic condenser
Inventor: NISHIDA NORIO
IPC: C25F3/04
Filed: 1993-03-22
Abstract: PURPOSE:To increase the capacitance per unit area by making the minus side peak current of the current waveform larger than the plus side peak current, and providing the OFF time for every end of the half cycle on the minus side. CONSTITUTION:In the etching of an electrode foil for an aluminium electrolytic condenser, the minus side peak current of the electrode waveform is made larger than the plus side peak current thereof. Further, the A.C. current having the OFF time, at which the etching current becomes zero every end of the minus half cycle, is used. Consequently, a thickn etching coating film is formed. The etching coating film is dissolved by chemical corrosion progressing at next OFF time, thereby being turned into the adequate coating film. Further, the time for diffusing gaseous hydrogen is obtained at the OFF time, thus forming more fine pit at next plus half-cycle. By this action, the surface area of the electrode foil for the aluminium electrolytic condenser is increased.

Abstract: PURPOSE:To prevent a photodetection system from being saturated without decreasing the signal-to-noise (S/N) ratio by controlling an optical phase modulator which varies the phase of local oscillation light so that only return light which returns at a desired observation position of an optical fiber to be measured is passed. CONSTITUTION:A continuous wave from a coherent light source 1 is branched by an optical branching device 2 and one continuous wave becomes a coherent light pulse through an intermittence type optical switch 3 and enters the optical fiber 5 to be measured through a photocoupler 4. The other continuous wave becomes local oscillation light, which is incident on the photocoupler 4 through the optical phase modulator 8 and coupled with the return light from the optical fiber 5 to be measured. At this time, the phase of the local oscillation light is varied and only the return light returning from the desired observation position of the optical fiber 5 to be measured is increased mutually when coupled with the local oscillation light. For the purpose, electric pulses generated by a pulse generator 6 are delayed and has pulse width and pulse level controlled optionally by a pulse controller 9, and the pulses are converted by an optical phase modulator driver into an optical-phase-modulator driving signal to operate the optical phase modulator 8.
