Patent JP-H01187979-A (JP)
Title: Semiconductor device
Inventor: IKI SHIGEO
IPC: H01L21/338
Filed: 1988-01-22
Abstract: PURPOSE:To increase drain breakdown strength without augmenting source resistance, and to obtain a semiconductor device having excellent characteristics and high reliability in a high-frequency region by asymmetrically forming the gradient of the side face of a recess on the source electrode side and the gradient of the side face of the recess on the drain electrode side. CONSTITUTION:In a field-effect type transistor having recess structure in a gate electrode 3 section, the gradient of the side face 7 of a recess on the source electrode 1 side and the gradient of the side face 9 of the recess on the drain electrode 2 side are shaped asymmetrically. An angle theta2 formed by the base 8 of the recess and the wall 9 of the recess on the drain side is made larger than that theta1 shaped by the base 8 of the recess and the wall 7 of the recess on the source side. Consequently, the thick region of an active layer 5 between the wall 7 of the recess on the source side and a source electrode 1 is formed in wide size, and the thin region of the active layer 5 between the wall 7 of the recess on the source side and a gate electrode 3 is shaped in narrow size, thus lowering source resistance. Since the angle theta2 formed by the wall 9 of the recess on the drain side and the base 8 of the recess is brought to 90 deg. or more, field concentration at a corner section between the wall 9 and the base 8 is difficult to be generated, thus increasing breakdown strength between gate- drain.

Title: Operation control device for air conditioner
Inventor: IKEDA JIYUICHI
IPC: F24F11/02
Filed: 1984-01-26
Abstract: PURPOSE:To secure the capacity of an air conditioner as much as possible and protect a frequency converter from overcurrent by a method wherein a revolving number variable type compressor is driven at a revolving number in accordance with a predetermined frequency in which the operating current of the device becomes lower than the maximum allowable current value of the frequency converter, upon the overcurrent of the frequency converter. CONSTITUTION:An output current detecting means 26, detecting the output current of the frequency converter 22, is connected to a microcomputer 21. The microcomputer generates a frequency setting signal so as to change the revolving number of the compressor 3 largely whenever a difference DELTAT between an actual temperature and a set value is large. Further, the microcomputer compares the output current value I of the frequency converter 22 with the maximum allowable electric current value IO based on the signal of the output current detecting means 26 and decides that it is overcurrent in case the output current value I exceeds the maximum allowable current value IO, thereafter, outputs the frequency setting signal to the frequency converter 22 so that the output current value I becomes lower than the maximum allowable current valve IO.

Title: Genlock system of secam signal
Inventor: SUZUKI YUKIO
IPC: H04N9/47
Filed: 1983-01-31
Abstract: PURPOSE:To exclude a pre-emhasizing circuit by applying the synchronizing separation to a genlock signal to extract a synchronizing signal, extracting a color signal out of a still burst signal, and superposing two pulses to feed them to a camera head through a cable. CONSTITUTION:On an operation panel 3, a synchronizing signal 10 is extracted out of a genlock input signal 6 through a synchronizing separator circuit. At the same time, color signal DR and DB are discriminated by a frequency demodulator within the panel 3 by gating the still burst parts 8 and 9 of the signal 6 and by making use of the difference between frequencies fOR and fOB. Thus, a DR or DB discriminating pulse 11 is produced. Then a composite pulse of signals 10 and 11 is produced, and a genlock signal 5 (shown in the diagram) is sent to a camera head 1 via a cable 2. This signal 5 contains no high frequency, and therefore a pre-emphasizing signal is eliminated. Furthermore, no beat disturbance is produced since the frequency shift is applied to the frequency fOR or fOB by the color even though two types of SECAM signals are transmitted through a single cable.

Title: Disk player
Inventor: KATO MASAHIRO
IPC: G11B7/095
Filed: 1999-01-21
Abstract: PROBLEM TO BE SOLVED: To provide a disk player provided with a pre-pit detection circuit preventing a lowering of a pre-pit detection margin due to a detection delay, having high detective precision and resistant to a noise. SOLUTION: A photodetector receiving a reflection beam from a DVD-RW (rewritable) is divided into four areas of A, B, C, D, and respective areas output detection signals. A delay of Δt appears for a pre-pit on the disk by a characteristic of a phase pit. First of all, after difference signals between A-C and D-B are respectively obtained, a phase difference pulse showing a phase difference between both is generated, and after it is integrated, it is held by a sample pulse outputted accompanying the 14T space detection, and a control voltage proportional to the phase difference is generated. A delay time of a voltage control delay line is controlled by the control voltage, and a correction signal (D-B)' delaying the difference signal D-B is obtained.  Then, by outputting a pre-pit detection signal (A-C)+(D-B)', a detection margin m is secured, and an effect due to the fluctuation of the noise, etc., is reduced.

Title: Burst error detection system
Inventor: YAMASHITA MASAHIRO
IPC: H04L1/00
Filed: 1978-02-10
Abstract: PURPOSE:To detect exactly the generation of burst error in a short time by adding a counter and a comparator circuit in an error correcting decoder. CONSTITUTION:Counter CT is reset at every N-bound length of convolutional code and counts the number of pulses of syndrome sequence signals which are generated in the N-bound length time. A threshold number is set to comparator circuit CP previously so that the output of compatator circuit CP can be obtained when the number of outputs of counter CT has exceeded the threshold number, and as a result, the burst error in the N-bound length time can be decided immediately.

Furthermore, the output of the circuit 3 is supplied to a phase detecting circuit 4, and the output waveform of the circuit 3 is sampled to detect the phase of the output waveform. Then the circuit 4 detects a waveform shift when the 10BIp transmission code has an error. In such a way, an error is detected with a simple circuit constitution.

Title: Paper rear end detecting method
Inventor: NAMIKAWA OSAMU
IPC: G06K15/16
Filed: 1987-01-23
Abstract: PURPOSE:To prevent erroneous judgment due to a binding hole by detecting the existence of a sheet of paper by means of a pair of opposite optical sensors, advancing a sheet of paper by a defined quantity when a sheet of paper is not detected and again detecting the existence of a sheet of paper and, when a sheet of paper is detected, returning said sheet of paper to its original position. CONSTITUTION:The existence of a sheet of paper 1 is detected by a light emitting element 2 and a light receiving element 3 which are opposite to each other. When a signal indicating the empty of a sheet of paper 1 is outputted, a sheet of paper 1 is advanced by a defined quantity via a driving device. And, if a signal indicating the existence of a sheet of paper is detected during or after the end of advancing, the sheet of paper is returned back to the original position by judging that the first paper empty signal is outputted due to a binding hole, and a print starting signal is outputted. When a sheet of paper 1 does not actually exists, the detected signal of empty of paper is continuously outputted. Thereby, the erroneous judgment of the empty of paper due to a binding hole can be easily avoided.

IPC: E01C19/48
Filed: 1998-01-27
Abstract: PROBLEM TO BE SOLVED: To enlarge the field of an operator's front view and to facilitate the loading and unloading of a spread-leveling machine. SOLUTION: A power device 8 is provided behind a complex material hopper, and an emulsion tank 7 higher than a power device 8 is provided between the power device 8 and a driver's seat 5, and the position of the center of gravity of a spread-leveling machine in the case of the empty emulsion tank 7 is set up at an about center in all directions of a travel device 3a. Since the rate of bad influence given to the field of front view is small even if the tall emulsion tank 7 exists just before an operater, he can see up to near a car 3 running on a front road surface on account of an enlarged vision angle. In addition, since the center of gravity exists at an about longitudinal center of the travel device to make the spread-leveling machine difficult to turn into an incorrect posture, it becomes easy to load it on a trailer or to unload it from the trailer using an inclined board.
