Title: Visual field angle limiter and image display device formed by using the same
Inventor: CHINO EIJI
IPC: G02F1/1333
Filed: 1995-09-06
Abstract: PROBLEM TO BE SOLVED: To make the viewing of a display surface from a specific bearing infeasible and to assure the confidentiality of display contents by using a liquid crystal high polymer combined layer and enhancing the light scattering intensity to the region above the prescribed visual field angle in the specific bearing. SOLUTION: A visual field angle limiter 20 is arranged on the display surface of a TN type liquid crystal display device 10 of a reflection type. Transparent electrodes 22, 24 are formed on the inner side of transparent substrates 21 and 25 and high polymer precursors and liquid crystals are mixed and sealed therebetween. The high polymers are cured by the irradiation with UV rays and simultaneously the phase sepn. of the liquid crystals and the high polymers is caused. The liquid crystal molecules are oriented in an electric field direction and the light scattering state is resulted by the difference in the refractive index between the liquid crystals and the high polymers by which the liquid crystals are made turbid when an AC voltage is impressed at the cells of the high transmittance formed in such a manner.  Since this scattering intensity is particularly strong in the magnetic declination range, the display contents of the liquid crystal display device 10 are made confidential from surrounding people by specifying this magnetic declination range at the prescribed direction.

Title: Semiconductor laser
Inventor: KOMORI MASAAKI
IPC: H01S5/12
Filed: 1999-08-17
Abstract: PROBLEM TO BE SOLVED: To increase the degree of freedom in the element design of a single longitudinal mode oscillation semiconductor laser by forming a structure having periodically varying refractive index or a structure having periodically varying laser gain in a light confinement region or a current constriction region. SOLUTION: A light confinement region 52 having a diffraction grating structure 54 is formed on the side face 51 of an active layer 50. Leakage of light 55 from the side face 51 of the active layer 50 is varied drastically by periodic modulation of refractive index caused by the diffraction grating structure 54. Consequently, single mode oscillation is effected. The active layer 50 is independent from the diffraction grating structure 54. More specifically, no periodic conductivity modulation region exist on the current path in a semiconductor laser. Consequently, carriers required for laser emission can be injected effectively into the active layer 50. In other words, a gain coupling part required for single mode oscillation design can be designed independently and the degree of freedom of design is increased.

Title: Magnetic recording and reproducing device
Inventor: KAMIYA SHINJI
IPC: H04N5/783
Filed: 1991-09-11
Abstract: PURPOSE:To improve the picture quality by reproducing a video/control signal from a first/second track group by a first/second magnetic head and moving the second magnetic head along the second track. CONSTITUTION:A control head driving device 25 moves a control head 6 along a control track 28 in directions of arrows 29 and 30 based on the command of a microcomputer 8 during special reproducing. The computer 8 moves the head 6 and counts the number of pulses of a running control signal 3 to discriminate the recording mode of the signal recorded on a magnetic tape 1. The video signal is recorded on the first track at intervals preliminarily set in accordance with this recording mode, and the control signal is written in the second track. First and second magnetic heads reproduce signals from first and second tracks respectively. Since the speed is optimized because a driving device 25 runs or stops the tape 1 in the lengthwise direction at this time, a good picture quality is obtained.

Abstract: PURPOSE:To miniaturize an outer cooling container and reduce an amount of use of refrigerant by a method wherein an ice making device is comprised of a storage tank for storing frozen liquid, an external cooler connected to the storing tank through a liquid droplet supplying pipe and an ultrasonic oscillator for generating fine liquid droplets from the frozen liquid. CONSTITUTION:As vibration is applied by an ultrasonic oscillator 20 fixed to a storage tank 3, fine liquid droplets are generated at a liquid surface within the storage tank 3 and the liquid droplets are filled at an upper space in the storage tank 3. As high pressure gas is fed from a high pressure gas supplying pipe 6 to an injection nozzle 4, the ultra-fine liquid droplets generate a negative pressure at the injection nozzle 4 and then the liquid droplets are sucked into the outer cooling container 1. Since the interior of the external cooling container 1 and the injection nozzle 4 are cooled by refrigerant fed from a refrigerant supplying pipe 8, the ultra-fine liquid droplets are iced to generate fine frozen particles. The fine frozen particles pass through the injection nozzle 4 and then are injected toward the surface of the washed solid material such as a semiconductor wafer or the like. Occurrence of liquid droplets is caused by the ultrasonic oscillator, a speed of the liquid droplets can be decreased, a heat exchanging time with the refrigerant can be increased and then it is possible to provide a small-sized device and to reduce an amount of supplying refrigerant.
