Title: Constant impedance output circuit
IPC: H03F3/345
Filed: 1992-03-18
Abstract: PURPOSE:To provide a constant impedance characteristic even against an input signal of large amplitude by connecting a first and a second impedance elements to a MOS transistor of a source follower. CONSTITUTION:Between a gate of a MOS transistor TR and an input terminal A, a resistance Rg1 being a first impedance element is connected, and between the gate of the TR and its source, a resistance Rgs being a second impedance element is connected. In such a state, by an operation of the Rg1 and Rgs, first of all, a potential difference VAB between terminals A, B is subjected to voltage division in a ratio of Rgs/(Rgt+Rgs), and influence by a VAB fluctuation becomes small. Also, a current for flowing to the gate by the Rgs is shunted and supplied to a load side, by which the Rg1 and Rgs execute an operation for preventing a rise of an output impedance. In such a way, as an effect of the Rg1 and Rgs, the output impedance can be made constant against a fluctuation of the load potential.

Filed: 1998-03-12
Abstract: PROBLEM TO BE SOLVED: To provide an extraction method of a nucleic acid by which the nucleic acid included in a biological sample is efficiently separated and extracted by a simple treating operation without requiring high centrifugal force and cooling operation. SOLUTION: A biological sample is subjected to a pretreatment for eluting the nucleic acid, and a water-insoluble organic solvent and an aqueous solution containing a highly concentrated inorganic salt and a buffer are added to the eluted liquid to carry out liquid layer separation into an aqueous layer containing the nucleic acid and an organic solvent layer containing no nucleic acid. The liquid layer separation is promoted by providing a centrifugal force and simultaneously a solidified layer is formed on the interface of the aqueous layer and the organic solvent layer. The aqueous layer containing the nucleic acid is fractionated from the separated mixture in the method for extracting the nucleic acid. The water-insoluble organic solvent layer contains a dissolved water-insoluble high molecular compound.

Title: Distance measuring device
Inventor: HAYASHI SHIYUUICHI
IPC: G02B7/32
Filed: 1984-03-30
Abstract: PURPOSE:To perform signal processing by the same circuit and to improve the precision of distance detection by processing two photoelectric outputs of an optical position detector which corresponds to image formation positions of spot light on time-division basis. CONSTITUTION:Output photocurrents I1 and I2 of the optical position detector 7 vary in level with the image formation position of reflected spot light which is emitted by an infrared-light emitting diode 3 and reflected by a subject.

Title: Satellite communication system
Inventor: TSUNODA KENICHI
IPC: H04B7/208
Filed: 1982-04-13
Abstract: PURPOSE:To improve the utilization efficiency of frequency and satellite power, by using the frequency of a pilot signa time-sharingly by a pilot signal for AFC and AGC and a signal for communication. CONSTITUTION:Control and response signals in an SCPC system which use one carrier in each telephone channel are transmitted time-sharingly at the time interval of frame length gamma as shown in the figure. The transmitted signal consists of a pilot signal burst 1, a control signal burst 2 and a response signal burst such as response/calling signal transmitted from each station to be controlled. Since the frequency of an oscillator in a satellite repeater station part is slightly changed and the loss of a transmission line is not changed suddenly, the transmission purpose is sufficiently attained and the utilization efficiency is improved even if the pilot signal for AFC and AGC is transmitted time-sharlingly.

Title: Gas laser device
Inventor: OKAMOTO NOBORU
IPC: H01S3/038
Filed: 1987-03-18
Abstract: PURPOSE:To stabilize an output by rapidly annihilating shock waves along the direction of separation of a main electrode by a shock absorber. CONSTITUTION:When a high voltage power 8 is operated, discharge is generated among upper/lower pin electrodes 5, 6, space between a cathode 3 and an anode 4 is pre-ionized by ultraviolet rays by the discharge, and main discharge is generated. Shock waves in the direction of the arrow (a) with the main discharge are annihilated in a short time, but shock waves in the direction (b) collide with the mutually opposed surfaces of the cathode 3 and the anode 4. Shocks are absorbed by the elastic deformation of a shock absorber 14 in shock waves colliding with a discharge member for the anode 4 in the shock waves. Accordingly, shock waves are quenched in a short time, thus preventing an unstable state from main discharge.

Title: Hydraulic control device for clutch of vessel
Inventor: HOTTA MIKIO
IPC: F16D48/00
Filed: 1996-03-18
Abstract: PROBLEM TO BE SOLVED: To adapt an identical vessel decelerating reversing gear to a mechanical and an electronic control type system by operating a low speed sailing lever operating a low speed valve with an electronic control system through an actuator while a conventional forward/reverse selector valve and the low speed valve, are used as usual. SOLUTION: In a vessel decelerating reversing gear which is so constituted as to be equipped with a low speed valve V1 and a low speed sailing lever L1 operating the low speed valve V1, the angle of the low speed sailing lever L1 of the low speed valve V1 is controlled based on the revolution speed of an engine mounted as an input signal. In the case such as control for the enlargement of a trawling range as a pattern at the time of raising engine revolution, and a reduction in engagement shock caused by making the lever speed slower just before an engaging point and the like, hydraulic control is thereby executed in response to the angle of the low speed sailing lever L1 of the low speed valve V1.  Besides, on condition that a neutral switch can be turned ON/OFF, the angle of the low speed sailing lever L1 of the low speed valve V1 is controlled, so that responsiveness is thereby improved.
