Title: A-d converter
Inventor: HAIKAWA YUKIHIKO
IPC: H03M1/10
Filed: 1981-02-19
Abstract: PURPOSE:To increase a conversion speed by storing a memory with data of a conversion error value to be corrected in advance. CONSTITUTION:The conversion time of an A-D converter used for PCM audio equipment should considerably be short because the number of AD-converted bits is great. Therefore, when an A-D converter 7 using a D-A converter 3 having a long settling time is operated by a high-frequency clock pulse, the A-D converter 7 is unable to follow up the input voltage of an analog input signal and its output A-D converter data contains a constant amount of conversion errors. The data of the conversion errors is stored in a memory 11 previously and the A-D converter output data of the A-D converter 7 is corrected by the data of the conversion errors stored in the memory 11, thus increasing a conversion speed.

Title: Forging method of spiral parts
Inventor: TSUKAMOTO HIDEHIKO
IPC: B21K1/30
Filed: 1983-02-17
Abstract: PURPOSE:To forge easily spiral parts having good shape and quality by allowing the lubricant forced into the spacing between the blank material in a die and the die to remain in the die under a specified pressure until the forging is completed. CONSTITUTION:A blank material A is set in a die 5 and is pressed with a punch 4. A lubricant B is fed under the prescribed pressure in the spacing between the die 5 and the material A through a lubricant passage 7 by a lubricant feeder 6 at the point of the time when the material A is filled in the die 5. When the pressurization on the punch 4 is continued, the material A is smoothly fitted to the die 5 by the lubricant B and is easily molded. On the other hand, the lubricant B is escaped through a relief valve 10 into a tank 11 upon pressurizing of the punch 4 so that the pressure of the lubricant B in the die 4 can be maintained constant.

Title: Photoelectric conversion logical unit
Inventor: SUGATA TAKAYUKI
IPC: H03K3/42
Filed: 1978-03-04
Abstract: PURPOSE:To produce a photoelectric conversion logical unit which can execute the logical operation of optical signals in an ultrahigh speed without a laser medium. CONSTITUTION:Center conductors 2 and 3, external conductor 5 and light receiving regions 6 to 8 of a distribution constant line are formed on semi-insulating  substrate 1. When signal light A is incident onto light receiving region 6, carrier is  generated near the surface of the substrate of this part, and the region becomes a conductive layer and is short-circuited. However, the signal is not transferred to the  distribution constant line in the right from power source E because of regions 7 and  8. Only when signals A, B and C are incident simultaneously, center conductors 2  and 3 are made conductive, and the pulse is steps are propagated. The AND output  of lights A, B and C is obtained. The pulse is reflected at short-circuit end 10, and  an opposite-polarity and equivalent- amplitude pulse is returned and overlapped.  The pulse of negative and positive polarities of a pulse width determined by the reciprocating time of distance l is obtained at point 9, and only one polarity is  amplified in 12 to obtain single narrow-width pulse V. Meanwhile, the reflection wave propagated to the left is absorbed by matching circuit 11. Now, the pulse propagation velocity in the substrate is approximately 0.4 times as high as light  velocity.

Title: Liquid level sensor
Inventor: TOYAMA HIROSHI
IPC: G01F23/22
Filed: 1996-02-09
Abstract: PROBLEM TO BE SOLVED: To provide a liquid level sensor which can deal with temporary liquid level drop or fluctuation of battery voltage through simple structure. SOLUTION: A thermistor 1 having negative resistance characteristics is disposed at a position corresponding to the lowest allowable liquid level. The thermistor 1 is connected in parallel with a Zener diode 2 and a warning bulb 3 is inserted in series between a battery and the parallel circuit of thermistor 1 and Zener diode 2. When the liquid level drops below the lowest allowable liquid level, the thermistor 1 is exposed to the air and the resistance thereof decreases below a predetermined value. Consequently, the warning bulb 3 is lighted to alarm that the liquid level is lower than the lowest allowable level. Since the battery voltage being applied to the thermistor 1 is limited by the Zener diode 2, erroneous alarm due to temporary liquid level drop or fluctuation of battery voltage can be suppressed.

Title: Fuse
Inventor: ENDO TAKAO
IPC: H01H85/0445
Filed: 1996-02-13
Abstract: PROBLEM TO BE SOLVED: To quickly and accurately break current even at the time of slice short circuiting or short circuiting at a low current value close to an allowable current by forming a fusing part through closely converging a plurality of strands in each of which a conductive small diameter wire is covered with a thin insulating outer skin. SOLUTION: The fuse 10 is so constituted that its fusing part 14 is formed out of a plurality of strands 12 which are closely converged. Each strand 12 in the fusing part 14 is mutually insulated by a thin insulating outer skin 22. Since the fusing part 14 is formed out of a bundle of the strands 12 mutually insulated, when the strands 12 at the fusing part 14 are heated by low current close to an allowable value, the strands 12 at the center are affected by the heat radiation of the strands at the outer part.  For this reason, even if the strands 12 at the outer part become low in temperature, the strands 12 at the center keep rising in temperature, the strands 12 start fusing from the center part of the bundle so as to allow a current value flowing the outer circumferential strands of the bundle to be increased, and the whole of the strands are finally fused, so that current is thereby isolated.
