IPC: D05B49/02
Filed: 1988-10-20
Abstract: PURPOSE:To enable a thread to be prevented from coiling round a thread take-up lever with no generation of rubbing noise by protruding a front edge from a thread, pulled when the thread take-up lever reaches a forward end, further curving a portion engaging a loop of thread, released from the thread take-up lever, to be formed for the loop of the thread to easily slip off. CONSTITUTION:A thread take-up lever cover 4, mounting its both right and left ends by screw stopping to a boss part 7 of a machine frame and covering a locus of a thread take-up lever 1, flexes the section to be formed into a squared shape with one end open releasing the total surface by a notch, and forming a protruding part 4a in each front edge of upper and bottom walls, the protruding part 4a is smoothly curved in its both right and left sides. A thread hook part 1a in the point end of the thread take-up lever reciprocates protruding from a front edge of the thread take-up lever cover 4, and the protruding part 4a protrudes from a locus in the time of return motion while from a thread 3 pulled when the thread take-up lever 1 reaches a forward moving side, further the protruding part 4a, being placed in the inner side from a locus in the time of forward motion, is formed so as to be prevented from protruding from said locus. One side 4b of the protruding part is engaged with a loop of the thread when the released thread from the thread take-up lever begins to loosen in its return motion.

Title: Optical disk device
Inventor: YAMAGUCHI TAKESHI
IPC: G11B7/0045
Filed: 1985-11-25
Abstract: PURPOSE:To correct the length of a recording bit at high accuracy by constituting such that the duty ratio of a reproducing signal at a trial recording is detected and a recording duty ratio at the time of recording after that time is corrected by an amount corresponding to the deviation quantity. CONSTITUTION:Receiving a recording correction instruction from an optical disk device control part 1 at the time of a trial recording, a recording correction control part 11 causes a recording pulse generator circuit 3 to switch a recording pulse train to a one with a single period integer-times a recording bit period. In order to make the duty ratio of a reproduced recording pulse constant, the deviation of the duty ratio is obtained from that in the reproduced signal. At the time of recording information, the duty ratio is previously deviated in correspondence to said deviation, and the duty ratio of the reproduced pulse is kept at the prescribed value. The correction accuracy of the period of an input clock 403 in an up/down counter 201 can be obtained and made sufficiently smaller that the length of the recording bit, thereby attaining correction at high accuracy.

Title: High voltage ac thyristor switch device
Inventor: SEKI KENZABURO
IPC: H03K17/725
Filed: 1986-11-10
Abstract: PURPOSE:To attain reduction of cost of the titled switch device and also to increase the contact lifetime by forming a switch circuit with a thyristor adverse parallel connector and a mechanical breaker and using no thyristor element for a single phase component to secure a low resistor. CONSTITUTION:A thyristor connector 25 of an R-phase is ignited at first at a zero point of the anode-cathode voltage of a U-phase thyristor. Thus a single phase AC current flows toward an S-phase from the R-phase. Then a thyristor adverse parallel connector 27 is ignited at a time point when the anode-cathode voltage of a W-phase thyristor is set at 0V. Thus a 3-phase AC current flows. Then a parallel breaker 28 is applied and a commutation loop is formed with conductors 25 and 27 or a low resistor 26 and a main pole of a breaker 28. Thus the U-phase and W-phase can use the forward voltage drops of elements 25 and 27 as the commutation current sources and the drop of potential of the resistor 26 serves as a commutation current source for a V-phase. Furthermore time constant is reduced together with reduction of the commutation time. Both connectors 25 and 27 are ignited in an open action mode with the breaker 28 opened. Then the connectors 25 and 27 are turned off.

Title: Automatic gain control circuit
Inventor: IDE HIROYUKI
IPC: H04N5/14
Filed: 1986-11-07
Abstract: PURPOSE:To make the screen bright by adopting two-stage of operating ranges for an AGC circuit so as to place the priority to the S/N when the brightness of the screen is not so deficient and increasing the gain if the screen becomes darker to give insufficient observation. CONSTITUTION:When an input video signal level is over a level A, since the level of the output of a 1st variable gain amplifier circuit 1 is always over J, an output of a level comparator circuit 8 opens the switch circuit 5, a 2nd variable gain amplifier circuit 2 does not amplify the signal and the output of the 1st variable gain amplifier circuit 1 is outputted as it is to an output terminal OUT. Thus, when the illuminance of an object is high, the output level keeps a high level. When the input video signal level is within levels C-D, the switch circuit 5 is closed and the output of the 2nd variable gain amplifier circuit 2 is fixed to the level J by the gain control signal GC2 and when the input video signal level is below the level D, the gain limit circuit 7 fixes the 2nd variable gain amplifier circuit 2 to the maximum gain. Thus, if the illuminance of an object is lowered, the sensitivity is increased until the object is confirmed on the screen.

Title: Engine-driven air conditioner and reserve tank therefor
Inventor: SUZUKI HIROSHI
IPC: F01P11/00
Filed: 1995-09-21
Abstract: PROBLEM TO BE SOLVED: To avoid the stop of an engine based on the decrease of engine cooling water by providing a device for opening a feed valve in a feed water pipeline, connected to a reserve tank, for the specified time during the operation of a level detecting float switch of an engine-driven air conditioner. SOLUTION: A signal from a float switch 17 is inputted to open a feed valve 21, and after the lapse of the preset specified time, the feed valve 21 is closed. When engine cooling water is thereby supplied into a reserve tank 16 from a feed water pipeline 20 via the feed valve 21, the level of engine cooling water 22 rises, and the float switch 17 is switched off. Since engine cooling water is thus supplied automatically into the reserve tank during the operation of the float switch 17, the stop of an engine 1 can be avoided. A float 17A can be pulled out of a fitting opening 24 by removing a tank cap 18 from the fitting opening 24, so that the float switch can be fitted/removed easily, and cost can be reduced.

Title: Photoelectric converter
Inventor: IZUKAWA KAZUHIRO
IPC: H04N5/372
Filed: 1990-10-05
Abstract: PURPOSE:To reduce the effect of noise by keeping a video signal to a state of information before write when the information from the photoelectric conversion element is written in a semiconductor memory. CONSTITUTION:D/A converters 25, 26, 27 sample a data at a rise of a DA-CK signal and hold an output. When a read.write signal (R/W signal) is 0 and the DA-CK signal is unchanged, output signal DA-OUT from the D/A converters 25, 26, 27 keep a value just before the read.write signal (R/W signal) changes from 1 to 0. Then when picture information is written in semiconductor memories 22, 23, 24, the same output as that of a just adjacent picture element on a TV screen is kept. Thus, the disturbance in the TV pattern is less.

Title: Multitrack magnetic head
Inventor: YODA HIROSHI
IPC: G11B5/29
Filed: 1988-10-21
Abstract: PURPOSE:To maintain crosstalks between heads extremely small by disposing plural head chips which diagonally crimp magnetic metallic cores on one base in such a manner that the track loci do not overlap on each other. CONSTITUTION:The magnetic metallic core 1 is crimped from both sides by nonmagnetic substrates 2 in such a manner as to be held diagonal with a head chip end face 7 to constitute the head chip. Such plural head chips are disposed on one head base 5 in such a manner that the loci of the respective tracks thereof do not overlap on each other and do not face each other at end faces 8, 9 of the chips adjacent to all the magnetic cores. Since the magnetic metallic cores 1 are formed diagonally with the end faces 7 in such a manner, the positions of the magnetic metallic cores at the end faces 8, 9 of the adjacent substrate are sufficiently parted in distance even if the head chips are in contact with each other. The crosstalks are thus maintained sufficiently small.
