Title: Video signal reproducing device
Inventor: HINE TATSUYA
IPC: H04N5/937
Filed: 1994-08-19
Abstract: PURPOSE: To provide a video signal reproducing device which can displays a noise-free excellent search image at a liquid crystal display part. CONSTITUTION: At a point t1 of time, the signal level V1 of the detection signal SDET of a reproduced signal SPD is sampled. On the basis of the search speed of an even double-speed search, a hold control signal HD is held at low level 'L' at a point t2 of time which is a specific time later, and the signal level V2 of the signal SDET is sampled. The levels V1 and V2 are compared with each other and since V1 is larger than V2, the timing of the next high level 'H' of the signal HD is a time τ delayed behind a point t3 of time which is a specific time later to obtain a point t4 of time. When V1 and V2 are nearly equal to each other, the timing is set to the point t3 of time which is the specific time later and when V1 is smaller than V2, the timing is set time τ precedent to the point t3 of time.  Similarly, the signal level is sampled and compared and the timing of the signal HD is so controlled that the signals become equal. When the signal level of the signal SPB is small, the signal HD is held at 'H' to inhabit the display data at the liquid crystal display part from being rewritten.

Title: Angle detecting device
Inventor: HASEGAWA KOJI
IPC: G01D5/245
Filed: 1984-09-18
Abstract: PURPOSE:To easily adjust the origin of an angle detecting device as to a control system by adding a function which sets the origin on a variable basis. CONSTITUTION:An AC exciting signal is inputted from an exciting signal gener ating circuit 60. An angle phase converter outputs an AC detection signal which has a phase difference proportional to the rotational angles of resolvers 10a and 10b from the AC exciting signal. The phase difference between the AC exciting signal and AC detection signal is measured by the counter of a phase difference detecting circuit 20 as a corresponding time value. In this case, the initial value of the counter is set on a variable basis by counters 24a and 24b through initial value setters 40a and 40b. Consequently, the origin of the control system and the origin of the angle detecting device are matched electrically with each other, so the angle phase converter is easily incorporated in the control system.

Title: Resin seal type semiconductor device
Inventor: YAMAGUCHI MASAO
IPC: H01L23/28

Abstract: PURPOSE:To prevent the breaking of a semiconductor pellet and the disconnection of a wire positively by forming slit sections mutually facing from facing both side-surface sections while being positioned between one part of the exposed main surface of a metallic support plate and the semiconductor pellet and sealing a resin body to these slit sections. CONSTITUTION:A rectangular notch section 3 is shaped at one end of a metallic support plate 1 consisting of a Cu plate, and a semiconductor pellet 4 is fixed onto one main surface of the support plate 1 through solder, etc. A resin body 7 coats a lead leading-out side surface section 10c in a header while coating side surface sections 10a, 10b mutually facing while being adjoined to the side surface section 10c. Since one part of the resin body 7 is sealed into slit sections 8a, 8b, a resin is constrained in the slit sections, thus inhibiting sliding displacement due to a difference between the thermal expansion coefficients of the resin and the support plate by walls 8a', 8b' in the slit sections in front of the semiconductor pellet 4.

Title: Current amplifier
Inventor: FUIRITSUPU ESU KUROSUBII
IPC: H03F3/347
Filed: 1990-07-24
Abstract: PURPOSE:To obtain a current amplifier whose frequency response is improved with less interconnection by using an independent current path of an emitter current for the current amplifier so as to reduce the attenuation in a high frequency current. CONSTITUTION:An emitter current of transistors(TRs) 24a and 26a, and 24b and 26b is not summed but used for an input of a current mirror circuit of the next stage and undesired connection is removed, then the hand width of the circuit is increased. Then the phase of the emitter current of the independent current mirror circuit is shifted to other current mirror due to a collector-base capacitance, parasitic resistance and capacitance of other TRs or other causes at high frequencies. Thus, local cancellation is caused to high frequency components of the summed emitter current to decrease the band width. The current amplifier is a current amplifier more excellent than a current mirror or a cascade current amplifier in the frequency response of the current amplifier by means of the computer simulation.
