Title: Phase locked loop circuit
Inventor: KIDENA MINORU
IPC: H03L7/107
Filed: 1986-03-18
Abstract: PURPOSE:To decrease further the locking time of a variable frequency oscillator by using an analog switch to short-circuit an input of a series resistor of a loop filter and a dividing point of a divided damping resistor. CONSTITUTION:The loop filter 8 consists of a series resistor R1 and divided damping resistors R2, R3 and a capacitor C1. The analog switch S is connected between the input of the series resistor R1 and the dividing point of the damping resistors and when an output of a lock detector 7 detecting the synchronizing state of a phase comparator 1 is asynchronous, the analog switch S is closed. As a result, the phase comparator 1 and the buffer circuit 5 are connected by a synthesized resistor subjected to parallel connection of the resistors R1, R2. That is, the analog switch S is closed at the asynchronous state and the cut-off frequency of a low-pass filter is changed to 0.02Hz to reduce the locking time of a variable frequency oscillator 3 further than a conventional circuit.

Abstract: PURPOSE:To omit high temperature annealing, by performing selective epitaxial growth of a high concentration n-type GaAs layer only on an n-type GaAs operating layer. CONSTITUTION:On a semi-insulating GaAs substrate 11, an n-type GaAs operating layer 12 and a high-melting-point metal layer 13 are formed. Then, an SiO2 film is deposited on the layers 12 and 13. Anisotropic etching is performed, and only a side wall 16 is made to remain. On the layer 12, a high concentration n-type GaAs layer 15 is epitaxially grown. As a forming method of the layer 15, e.g., an organic metal-vaporp-phase deposition method and a molecular-beam epitaxial deposition method can be used. Then, an ohmic electrode metal film 17 is evaporated in a vacuum, and photoresist 18 is applied. Etching is performed, and the film 17 on the layer 13 and the side wall 16 is exposed. The exposed film 17 is removed by ion milling. Then, the remaining resist 19 is removed, and the film 17 is made to be an alloy. Thus a source electrode and a drain electrode are formed. Since the layer 15 is epitaxially grown, high temperature annealing is not required, and the selecting range for the gate electrode can be expanded.

Filed: 1980-05-12
Abstract: PURPOSE:To ensure both the watertigntness and the airtigntness with a simple constitution, by providing plural optical fiber storing grooves on the inner circumference surface of a metallic sleeve or the outer circumferential surface of a metallic bar and then storing the optical fibers in these storing grooves. CONSTITUTION:The optical fibers 12 are stored in the optical fiber storing grooves of a metallic bar 10, and the bar 10 is inserted into a metallic sleeve 9. Then both the sleeve 9 and bar 10 are heated up, and the molten solder is flowed into a filling part 13 to be solidified. Thus a sealing structure is obtained. The degree of shrinkage caused when both the sleeve 9 and the solder are cooled is larger than that caused when the bar 13 is cooled. As a result, a synergistic effect is produced between the self-strain force caused inside after solidification of the solder and the inherent adhesive strength of the solder itself. Thus the stable watertightness and airtightness can be obtained.

Title: Data management system for ic card
Inventor: NAGANOU SHIYUNICHI
IPC: G06F21/62
Filed: 1986-03-20
Abstract: PURPOSE:To apply a single memory device to the plural types of IC cards, therefore to reduce the costs of a memory device and the IC card, by inhibiting the rewriting operation of data for each storage in case the specific digit of the storage unit of a memory device incorporated to the IC card to store data is equal to the prescribed value. CONSTITUTION:A rewriting inhibition means reads the data on each storage to be rewritten in a data writing mode and checks whether the leading digit of the data is equal to 0 or 1. If the leading digit is equal to 0, it is decided that the rewriting action of each storage is inhibited to finish the operation. While said rewriting action is possible, therefore the new data is written for each storage in case said leading digit is equal to 1. Thus it is possible to form a uniform memory device an IC card and to inhibit or permit optionally the writing of the input data. Therefore just a single memory device can cope with various types of IC card, thereby reducing the costs of the memory device and the IC cards.

Abstract: PROBLEM TO BE SOLVED: To provide a method and a device for controlling displacement of a blade of a slicing machine which has a simple mechanism and can control the displacement of the blade. SOLUTION: Air current in a peripheral direction to be generated at a lower part of a blade 14 by the rotation of the blade 14 is guided by a tiltable fin 28 so as to make it flow to the bottom face of the blade 14. As a result, the blade 14 is pressed at its bottom face by wind pressure of the air current, and is displaced to the upper side.
