Title: Tape cassette
Inventor: OZAKI HIROSHI
IPC: G11B23/087
Filed: 1993-02-26
Abstract: PURPOSE:To prevent dropout from occurring at a recording and reproducing time. CONSTITUTION:A cassette back cover 25 is constituted of a first oscillating plate 26 provided with a first engagement body 34 which can be engaged with a first cam surface 11a and a second oscillating plate 27 provided with a second engagement body 38 which can be engaged with a second cam surface 13a. The plate 26 out of them is pressed in a cover opening direction by torsion springs 40 and 41. Since the plate 26 is oscillated in the cover opening direction and the plate 27 is oscillated in the cover opening direction independently of the oscillating action of the plate 26 at the same time when a cassette front cover 17 is operated to be turned in the cover opening direction, the back cover 25 can be added to the back side of the front cover 17 while a present opening angle is maintained and the protecting performance of a tape T can be enhanced.

Title: Exposure method and device
Inventor: OKI YASUSHI
IPC: G03F1/70
Filed: 1994-03-09
Abstract: PURPOSE:To eliminate the movable part for the relative positional change between the sensing material and the image formed thereon by a method wherein patterns are provided on reticles by using two or more exposure wavelengths and optical filters having different transmittivities to the exposure wavelengths. CONSTITUTION:A linearly periodical pattern is formed of an optical thin film comprising an interference filter on a reticle substrate 33. A part 31 having the characteristics of transmitting lambda1 but not transmitting lambda2 and another part 32 having inverse characteristics of not transmitting lambda1 but transmitting lambda2 of the same width are alternately arranged. The image of this reticle pattern is formed by illumination light of the wavelength of lambda1 and formed by the light lambda2. Through these procedures, the periodical pattern in the distribution of light intensity of light inversed in bright and shade to respective wavelengths can be taken.

Title: Discharge lamp lighting circuit
Inventor: FURUTA TAKASHI
IPC: H05B41/40
Filed: 1992-01-07
Abstract: PURPOSE:To compensate lowering in visual acuity by combining an oscillator which determines the lighting frequency of a discharge lamp, with a frequency varying circuit which gradually lowers the frequency with a specified time after the lamp has been lighted, and thereby increasing illuminance. CONSTITUTION:An oscillator 3 is started with a DC power supply 1 applied, a transistor 6 is repeatedly turned on and off. When the transistor is on, a filament is preheated via the filament of a lamp 9, capacity 10 and ballast inductance 8. And when the transistor is off, resonance occurs in capacity 4 and inductance 5. Generated voltage is divided by both capacity 10 and inductance 8 so as to be applied to both the electrode ends of the lamp 9. This action thereby allows a preheating state to be switched over to a lighting state. A frequency varying circuit 2 keeps sending a frequency lowering signal for the definite period of time immediately after the lamp has been lighted. As oscillated frequency is lowered, the current of the discharge lamp 9 is increase, and the beam of the lamp is also increased. The duration of the discharge lamp lighting is set to the time when human eyes start increasing the degree of fatigue, lowering in visual acuity owing to fatigue can be compensated by an increase in illuminance.

Title: Stopping method of motor compressor
Inventor: MORIMOTO MASAYUKI
IPC: F04B49/02
Filed: 1984-03-01
Abstract: PURPOSE:To make a motor compressor stoppable in silence, by once short-circuiting the operating condenser of an electric motor and, after energizing it with a continuous rating current, intercepting the current at the time of stopping the motor compressor. CONSTITUTION:A single-phase induction motor is so designed as to operate with small torque even if the capacity of an operating condenser comes to zero. Therefore, from time immediately after having a switch 31 closed, it shorts out an operating condenser 23 of a motor 21, and is directly connected to a power source whereby the motor 21 is made to continue its operation with small torque. Under this condition, however, it may not meet such a degree of torque so stong as to further continue compression so that the motor stalls by degrees due to back pressure at the discharge side in the long run, thereby resulting in stoppage sooner or later.

Title: Entrance optical apparatus for spectrometry
Inventor: OKUBO KAZUAKI
IPC: G01J3/02
Filed: 1991-03-06
Abstract: PURPOSE:To guide a lot of the diffusion light of a measuring light source to a spectrometer by condensing luminous flux components parallel to an optical axis by means of a concave mirror and a convex mirror to a point of the concave mirror where it confronts to the convex mirror, and using an optical fiber having a larger angular aperture than a solid angle to the convex mirror. CONSTITUTION:A concave mirror 3 has an optical axis on the same line as a normal of a diffuse transmission plate 2, with an aperture at the optical axis. A convex mirror 4 is located on the optical axis of the mirror 3, sharing the optical axis. The mirror 3 guides luminous flux components parallel to the optical axis among the diffusing light from the diffusion plate 2 to the mirror 4. The mirror 4 condenses the light to a point of the mirror 3 where the mirror 3 confronts to the mirror 4 and brings into an optical fiber 5 which guides the light to an incidence slit of a spectroscope. At this time, the solid angle to the mirror 4 is set smaller than the angular aperture of the fiber 5 and, the angle of incidence to the fiber 5 is restricted not to bring about the problem of the chromatic aberration at a projecting end of the fiber 5 by an aperture 6. Accordingly, it is possible to guide the diffusion light of the light source to the spectroscope as much as possible.
