Title: Vehicular lamp equipped with optical axis adjustment device
Inventor: OKADA SATORU
IPC: F21V14/04
Filed: 1997-03-27
Abstract: PROBLEM TO BE SOLVED: To prevent at low cost a decrease in the performance of a pivot bearing mechanism due to heat. SOLUTION: This vehicular lamp has a pivot 190 made of a synthetic resin, which is interposed between a movable reflector 13 made of a metal with high heat conductivity and a lamp housing 10 made of a synthetic resin with low heat resistance. As a result, the pivot 190 made of the synthetic resin can prevent the heat of a light source bulb located on the movable reflector 13 from being conducted to the lamp housing 10, eliminating the fear that a spherical recess 195 in the bearing 191 of the lamp housing 10 is thermally deformed and melted, resulting in a loose fit between the spherical recess 195 of the bearing 191 and the spherical part 192 of the pivot 190 and hence a decrease in the performance of a pivot bearing mechanism 19. Also, since the synthetic resin which is less heat-resistant and low-cost can be used directly for the lamp housing 10, an increase in cost can be avoided.

Title: Truing device
Inventor: IMAI TOMOYASU
IPC: B24B53/00
Filed: 1990-03-27
Abstract: PURPOSE:To heighten the fatigue strength of a crankshaft by providing command means for changing/controlling the rotating speed of at least one of a truer and a grinding wheel so as to make a rotating speed ratio between the truer and grinding wheel into a rotating speed ratio of the preset wheel surface roughness being large at curved parts and another rotating speed ratio at a straight line part. CONSTITUTION:At the time of truing a grinding wheel 12, provided with curved parts R1, R2 formed on both sides of the wheel peripheral surface and a straight line part S formed between both curved parts, by a truer 22 moving in the traverse direction along the wheel peripheral surface, the rotating speed of either a truer 22 or the wheel 12 is variably controlled by command means 36, 37 so that a rotating speed ratio between the truer 22 and wheel 12 is made into a rotating speed ratio of the preset wheel surface roughness being large at the curved parts and a rotating speed ratio other than the above-mentioned rotating speed ratio at the straight line part. Both side curved parts are thereby trued into the rough wheel face of good cutting performance, and the straight line part is trued into the fine irregular wheel surface, so that the fatigue strength of a crankshaft is improved.

Filed: 1995-03-31
Abstract: PURPOSE: To obtain the efficient interleave system by adding a 3rd error correction code to data comprising a digital video signal and a digital audio signal in a form of bit streams in the track direction. CONSTITUTION: Digital data are converted into a SYNC block format in which an information symbol length is n1, digital data converted into a SYNC block format are collected in a K2 SYNC block and recording digital data of one track are generated. Furthermore, data converted in the unit of tracks are collected to an n3 track to form an error correction block.

Title: Manufacturing of thin glass plate by float process
Inventor: KAMIDATE TAKAYOSHI
IPC: C03B18/06
Filed: 1981-05-20
Abstract: PURPOSE: To manufacture a high-quality thin glass plate having a thickness of ≤1mm,  especially about 0.2mm, by placing a barrier member having the top edge submerged in  a metal bath at the downstream of the other barrier forming a molten glass pool on  the molten metal bath.  
     CONSTITUTION: Molten glass 2 is supplied on the molten metal bath 7, and forms a molten glass pool 3 on the bath 7 by the first barrier member 11 traversing the bath  7. The second barrier member 12 having the top edge below the surface of the bath 7  and traversing the bath 7 is placed at the downstream of the member 11 and the  region in which the forming of the molten glass is essentially incomplete. Consequently, the glass 2 in the pool 3 is transferred trough the gap between the lower end of the  first barrier member 11 and the surface of the bath 7, immediately passed closely  above the top edge of the second member 12, and elongated. Since the amount of the  hot molten metal 17 flowing to the downstream of the member 12 is restricted, the  temperature difference along the thickness of the formed glass plate caused by the  heating of the lower surface of the glass 2 under formation to the desired thickness  can be diminished. The generation of stress in the glass plate can also be reduced  since the direction and speed of the glass 2 at the interface with the metal 17 are  nearly equal to those of the metal.

Title: High frequency switching circuit
Inventor: YAMAGUCHI YOSHITADA
IPC: H04N5/775
Filed: 1984-04-18
Abstract: PURPOSE:To increase the attenuation quantity in case where the amplifying action of a high frequency amplifying transistor TR is stopped, by connecting a switching diode to the collector of the high frequency amplifying TR in the forward direction. CONSTITUTION:When the output of a switch control part 33 is set to a high level, a switching TR37 is turned on, and the base of a high frequency amplifying TR11 is grounded, and therefore, the amplifying action of this TR11 is stopped. At this time, a current is not flowed to a switching diode 40 because the collector current of the TR11 is zero. Consequently, the impedance of the diode 40 is very large. Thus, the attenuation quantity in the case where the amplifying action of the amplifying TR11 is stopped is increased by this increase of the impedance of the diode 40.

Title: Base modulation type bipolar transistor
Inventor: SHIMIZU KATSUYA
IPC: H01L29/732
Filed: 1989-03-27
Abstract: PURPOSE:To operate at 3-terminals by energizing between a base contact region and an emitter region by forward bias, energizing a collector region in a reverse bias state with respect to the base contact region to modulate a base current flowing to a second base region, and obtaining an output having negative resistance characteristic. CONSTITUTION:When a reverse bias of a predetermined voltage or more is applied to collector regions 1, 2 and a base contact region 6, part of minority carrier poured in a second base region 3a is absorbed to a first gate region 8A by the forward bias between a base and an emitter. Part of the minority carrier is absorbed to a gate region 8 to generate a gate current IGi. The current IGi flows through a second gate region 8B from the regions 1, 3 partly to the regions 1, 2 toward the emitter, and the region 8 and the regions 1, 2 become the same potential. Thus, even if a gate electrode is not led to be externally connected to the collector, it can be operated with 3-terminals.
