Title: Gas laser device
Inventor: FUJIOKA TOMOO
IPC: H01S3/097
Filed: 1991-11-20
Abstract: PURPOSE:To increase the output of a laser beam by applying high frequency power to a reentrant resonator through a loop so as to perform high frequency discharge between plate-shaped electrodes. CONSTITUTION:A reentrant resonator comprises a plate-shaped electrodes 1a and 1b counterposed, a doughnut-shaped cavity 2, which surrounds these electrodes 1a and 1b, and a loop 3, which couples with this cavity 2. And, when high frequency power is applied from a high frequency power source to a reentrant resonator through the loop 3, high frequency discharge occurs in the space between the electrodes 1a and 1b, and the gas laser medium in the space can be pumped. At this time, the thickness of an ion sheath occurring between the electrodes 1a and 1b can be reduced by raising the frequency of the high frequency power. Accordingly, the space contributing to the laser oscillation can be widened. Thereby, a laser beam of large output can be obtained.

Title: Cosmetic sample
Inventor: IWAMI HARUHIKO
IPC: A45D33/38
Filed: 1994-12-07
Abstract: PURPOSE: To form a cosmetic sample additionally thinner so that these samples are bound to magazines and books by printing a base material with the cosmetics by using a gravure printing method. CONSTITUTION: This cosmetic sample 1 is formed by thinly printing one surface of the base material 2 consisting of a soft thin body, such as film or sheet made of a synthetic resin or paper, by using a gravure printing method. Namely, a roll 4 inscribed with a gravure plate on its peripheral surface is rotated while the roll is dipped in the cosmetics 3 made into ink by heating, etc. The excess components exclusive of the cosmetics put into the gravure patterns 5 are scraped off by a doctor 6. The base material 2 is brought into pressurized contact with the peripheral surface of the roll 4 to print the one surface of the base material 2 with the cosmetics 3. The thickness of the printed cosmetics 3 is extremely small and the base material is formable to the extremely smaller thickness than in the case of silk printing.

Abstract: PURPOSE:To make it possible to conduct an accurate relative positioning of a magnetic pole and a brush just by pushing a baseplate into a housing by installing a positioning piece which fits in a recessed part of an uneven part of the magnetic pole on the baseplate on which the brush is mounted. CONSTITUTION:As shown by the figure, a magnetic pole 1 has a flat part 1A on one end and an uneven part 1B on the other end. On a baseplate 8, a brush 10 is mounted which gets brought into contact with a bearing 9 and a commutator 7. A positioning piece 11 has a square-shaped cross section and is so installed on the inner face of the baseplate that a protruding part faces inwards. For positioning, the positioning piece 11 gets fit on the boundary part 1B' between the N pole and S pole in the uneven part 1B of the magnetic pole 1. Because the positioning piece 11 which fits in the recessed part of the uneven part of the magnetic pole 1 is mounted on the baseplate 8, a relative positioning of the brush and the magnetic pole is conducted automatically just by pushing the baseplate into a housing 2' so that the positioning piece may fit in the recessed part.

Title: Color printer
Inventor: YAMAMOTO HAJIME
IPC: G03G15/01
Filed: 1987-12-25
Abstract: PURPOSE:To print only a desired document in color by sticking a specific-color mark on a specific position of the document previously, discriminating whether or not there is the specific color at the specific position on the document at the time of reading, and determining whether the document is printed in color or in black and white according to the discrimination result. CONSTITUTION:A user sticks the specific-color mark on the specific position of the document to be printed in color. A solid-state image pickup element scans the specific position on the document to recognizes the specific-color mark at the specific position and then the printer is put in color mode automatically. A color document which need not be printed in color is printed in black and white unless the mark is stuck, and the entire surface of the document need not be scanned to recognize its color image. Consequently, even when documents after said processing is performed are loaded on, for example, an automatic document feeder, it is decided at each time whether or not there is a mark, so only desired documents are copied in color automatically.

Title: Photocoupler
Inventor: WADA YOSHIYUKI
IPC: H01L31/12
Filed: 1992-11-18
Abstract: PURPOSE:To prevent the malfunction of a photocoupler, and obtain a photocoupler capable of increasing resistance to dv/dt. CONSTITUTION:The distance between a light emitting diode and a photodiode as a photodetector is constituted to be equal to the distance between the light- emitting diode and a dummy photodiode. A photodiode 3.1 and a dummy photodiode 3.2 are formed in comb types or spiral types. Thereby the distance t1 between a light-emitting diode LED 3.3 and the photodiode 3.1 is made equal to the distance t2 between the LED 3.3 and the dummy photodiode 3.2. When noise dv/dt is applied across the primary side and the secondary side of a photocoupler, the noise is similarly applied to the photodiode 3.1 and the dummy photodiode 3.2, so that noise cancelling is enabled. In the conventional photocoupler of t1not equal to t2, the resistance to noise has been about 1000V/mus. In the photocoupler of t1=t2, the resistance to noise can be increased up to about 3000V/mus.

A low-voltage winding 30 formed in the same way is disposed coaxially with the high-voltage winding 20 to form a foil winding transformer.  Since the inner and the outer cylinders 24 and 25 are thicker than the conductive foil 21, the strength of the high-voltage winding 20 and the low-voltage winding 30 and the like is increased. Also, since the ends in the axial direction form electric field relieving parts, electric field relieving parts are accordingly provided with ease.
