Title: Radio wave key system
Inventor: SHIMIZU HIDEHIKO
IPC: E05B49/00
Filed: 1998-01-27
Abstract: PROBLEM TO BE SOLVED: To reduce useless transmissions and reduce consumption of batteries by transmitting ID signals in accordance with the output of an oscillation detection circuit only when oscillations are detected by the detection circuit provided in a portable instrument. SOLUTION: When oscillations are detected in an oscillation detection circuit 10 in a portable instrument 6, ID signals are outputted from a control circuit 9 to a transmission circuit 8 and oscillated in a high frequency and transmitted from a transmission antenna 7. ID signals transmitted from the instrument 6 are received in a receive circuit 3 through a receive antenna 2, in a receiver 1 mounted on a vehicle and compared with an ID registered in advance in a control circuit 4. When the compared result is correct, the locking/unlocking output power for a door is controlled. In this way, since IDs are not transmitted when oscillations are not detected in the instrument 6, the consumption of batteries can be reduced.

IPC: H04N7/00
Filed: 1989-01-25
Abstract: PURPOSE:To detect image block synchronization(phase) simultaneously by a synchronizing(phase) signal detected from a multitransmission frame by comprising the transmission frame after adjusting the information bit rate of the transmission frame and that of the block of an image signal at prescribed relation. CONSTITUTION:A system is comprised so that the transmission of (m)-th block of a digital image signal can be performed accurately with the l-th frame of the transmission frame 2 to perform the detection of transmission frame synchronization also with that of the image block synchronization. The picture(vertical) synchronizing signal 11 of an image can be attached, however, no block() synchronizing signal is required. Also, separation at every (m) blocks of the image is detected, and it is 1/m-frequency-divided, or a block counter provided in an image signal processing is reset by the synchronizing signal. In such a way, it is possible to perform the detection of block synchronization of the image simultaneosuly with the detection of transmission frame synchronization at a reception side, which requires no double constitution of a transmission synchronization detection circuit and an image synchronization circuit.

Abstract: PURPOSE:To improve the uniformity of etching of differently sized substrates by constituting an electrode on the side where the electrode faces a material to be etched in such a manner that the surface area of the electrode can be freely reduced and enlarged with respect to the sizes of the substrate. CONSTITUTION:A high-frequency voltage is impressed between the lower electrode 1 imposed with the substrate 3 disposed in a chamber 6 and the upper electrode 2 disposed to face said electrode by a high-frequency power source 5 and a gas is introduced into the chamber through a gas introducing port 7.

The upper electrode 2 of a plasma etching device constituted in the above-mentioned manner is constituted of at least >=2 sheets of blades sliding in arrow directions. The area of the upper electrode 2 is thereby changed according to the sizes of the substrate 3 by which the density distribution of the cations colliding against the material 4 to be etched is made uniform. The uniformity of etching is thus improved.

Title: Fault decision method in radio transmission channel
Inventor: KOIZUMI YOSHIKO
IPC: H04B17/00
Filed: 1994-02-08
Abstract: PURPOSE:To decide a fault occurrence location accurately by allowing a relay station to record monitor information of its own station for each prescribed period and to send worst monitor information to a terminal station among recorded monitor information over plural periods based on a monitor information request command from the terminal station. CONSTITUTION:Plural relay stations 2 record monitor information including an error rate in its own station for each prescribed period. Furthermore, a terminal station 1 designates sequentially a relay station 2 to send a monitor information request command thereto. The designated relay station 2 selects worst monitor information in which, e.g. an error rate is maximized among the monitor information over a prescribed period in reply to the monitor information request command and sends the worst case monitor information to the terminal station 1. The terminal station 1 collects the worst case monitor information from each relay station 2 and decides a fault location based on the sequence of production of the worst case monitor information. Since the decision is implemented by using a reception level or the like together with the error rate, the fault location is accurately decided.

Filed: 1990-01-24
Abstract: PURPOSE:To suppress the influence of disturbance by providing a third differentiating means, which generates a third order differential pulse by further differentiating an output pulse to be obtained from a second differentiating means, and measuring time difference between first and second zero cross points. CONSTITUTION:For the detection pulse of a proportional counter, a pulse is outputted with a delay starting characteristic to incident gamma, and a pulse is outputted with the fast starting characteristic to an incident recoil proton. When this detection pulse passes through a differential amplifier 2 and an integral amplifier 3, the waveform of semi-Gaussian is obtained. The peak point of the pulse waveform by the recoil proton appears before that of the pulse waveform caused by the gamma beam and when this pulse of the semi-Gaussian is passed through a second amplifier circuit 4, the second differential waveform is generated. Next, when the second order differential waveform is passed through a differential amplifier 20, the third order differential waveform is generated. This third order differential waveform is equipped with positive and negative polarity values and two zero cross points. The first and second zero cross points are detected by detection circuits 25 and 26 and based on the detection pulses of these circuits 25 and 26, a time measuring circuit 27 measures the time difference between the both zero cross points.

Abstract: PURPOSE:To evade a defective situation such as burning accompanying the idle operation of a pump by securely stopping the pump at a specific water level even if the absolute pressure in the space in a container varies owing to a difference between an inflow and an outflow. CONSTITUTION:Water dipping depth (h) is calculated by using the relative pressure DELTAP in the space S in the container, whose opening 2 is dipped in water, to outside air pressure as a factor and water is discharged when the arithmetic value becomes constant. This water level control unit stops the pump 5 from operating through a controller 4 when the water level arithmetic value at the time of a fall in water level accompanying water discharge is 0 and a water level varying speed is 0, thereby stopping discharging the water.

Abstract: PURPOSE:To prevent failure of a magnetic head generated from deflection of a cover by collision of an inject bar held at a frame unit with a cover body earlier than a carrier unit when this cover body is deflected by receiving a certain external force. CONSTITUTION:A hollow accepting part 3 of the magnetic disk recording and reproducing device is composed by combining the frame unit 1 and a cover 2 covering this unit 1 with each other. A magnetic disk 40 is accepted into this accepting part 3. The carrier unit 9 is held in the frame unit 1 and the unit 9 is housed in the accepting part 3.

Title: Method for manufacture of thin iron oxide film
Inventor: MAKINO KOUICHI
IPC: H01F41/18
Filed: 1979-02-14
Abstract: PURPOSE: To form a thin iron oxide film of the specified degree of oxidation on a substrate by checking the temperature rise in a substrate on which a thin film is to be formed and preventing the formation of an oxide on the target surface.  
     CONSTITUTION: When negative voltage of -2W-5kV is impressed on target 3, while an inert gas of 10 -2  Torr is being drawn into sealed chamber 5 from pipe 7, electric discharge takes place between target 3 and the inner wall of chamber 5, and positive ions in the plasma collide with target 3 and sputtering takes place. Atoms that have escaped from target 3 pass through the open window of chamber 5 and collide and react with the reaction gas drawn from reaction gas ejection port 10, and thereby an oxide compound is formed on substrate 1 as a thin iron oxide film. In this case, by varying the amount of oxygen in the reaction gas, it is possible to form iron oxides of different degrees of oxidation. Since the neighborhood of target 3 is filled with inert gas, no oxide is formed on the target surface due to the reaction with the reaction gas.
