Title: Warm air type electric leg warmer
Inventor: NISHIYAMA HARUNORI
IPC: F24H3/04
Filed: 1988-02-10
Abstract: PURPOSE:To realize an even temperature distribution inside a leg warmer framework by disposing an inverted truncated conical protrusion having air inlets and outlets nearly in the center of a reflector plate, an annular heater around the protrusion, a fan and a motor in the interior space in the protrusion, and an air guide above the fan. CONSTITUTION:The rotation of a fan 44 by a motor 47 generates an air flow (b), and, in response, cold air in the lower part of the leg warmer framework 31 is taken in to the space 46 through air inlets 37, which is then delivered to an annular heater 40 through air outlets 39. The cold air is heated by the heater 40, flows along the inclined guide 36 on a reflector plate 34, and is delivered through air outlets 45 to make the temperature distribution uniform in the space in the leg warmer framework 31. The radiation heat of the heater 40 is reflected to the space in the leg warmer framework 31 by the slope 38 of a protrusion 35 to heat up the space in the leg warmer framework 31. The power supply to the heater 40 is controlled by detecting the temperature derived from the temperature of a part of the air flow (b) adjusted by the function of the temperature or the space above the reflector plate 34 or the reflector plate 34 itself as the temperature of a heat generating unit 33 by means of a sensor element 53 built-in a detachable plug 52.

Abstract: PURPOSE:To provide a projection type display device in which the luminance of a video projected on a screen is made high and the unevenness of light is not caused in the video on the screen by using plural illuminating light sources. CONSTITUTION:Illuminating light beams from the respective illuminating light sources 21 and 22 are condensed on the reflection surfaces of corresponding reflection means 27 and 28 by condensing optical systems 31 and 32, and reflected to a condensing lens system 33 by the reflection means 27 and 28. The illuminating light beam condensing positions on the respective reflection surfaces are close to each other, and set near the object point of the lens system 33, so that the respective illuminating light beams are made incident on the lens system 33 in a state where they are superposed each other and become parallel beams. The illuminating light beam passing through the lens system 33 and made incident on a light intensity modulation means 14 becomes the light where the illuminating light beams from the plural illuminating light sources 21 and 22 are superposed and which has high luminous intensity, thereby making the luminance of the video projected on the screen by a projecting optical system 16 high.

IPC: B23Q17/20
Filed: 1982-02-25
Abstract: PURPOSE:To detect an abnormal state of each part of a screw,by irradiating light along a normal passing through the center of the screw, also scanning along the axial direction, and detecting a variation of this reflected light. CONSTITUTION:Light passes through a half-mirror 3, is scanned in the axial direction along a normal passing through the center of a screw to the screw 1, and becomes scanned incident light 2. Reflected light from the screw 1 is reflected by the mirror 3, and is made incident to a photoelectric element 4. In this case, light from a crest part 5, a root part 6 and an edge line part 7 of a screw is elongated on the same straight line, and is made incident to the element 4 efficiently. An electric signal obtained by the element 4 becomes a regular repeated waveform which conforms with the number of screw threads under the scanning area of the incident light 2. Accordingly, by detecting a variation of a maximum value 8b and a minimum value 8a of a signal waveform, and a part 8c extending from the maximum value to the minimum value, each abnormal state of the root part 6 of the screw, the crest part 5 of the screw and the edge line part 7 of the screw can be detected.

Abstract: PURPOSE:To realize a non-contacting recording/reproducing by impressing a voltage between a transparent conductive layer and a conductive layer, making an optical signal to be recorded incident to a semiconductor layer and recording by means of charges that accumulate in a depletion layer and a nitride layer formed in the semiconductor layer. CONSTITUTION:A beam from a light emitting mechanism 25 passes through a transparent substrate 14 and the transparent conductive layer 15 and reaches the photoconductive semiconductor layer 16. The layer 16 lowers its resistance value when lighted, accordingly, the voltage between the layer 15 and the conductive layer 20 is impressed to a single crystal n-type silicon part 17 to generate changes Q, and at the same time the depletion layer is formed. Further, the charges Q are accumulated in the nitride film 19 via an oxide film 18 because of tunnel effect, and thus the write of a signal is achieved. On the other hand at the time of reproducing, the variation the electrostatic capacity caused by the depletion layer is detected as a voltage variation. In such a way, a non-contacting recording/reproducing can be executed, a damage on a recording medium due to abrasion can be prevented, and the data can be stored for a long time.

Title: Field effect transistor and its manufacture
Inventor: KUNIHIRO KAZUAKI
IPC: H01L21/335
Filed: 1998-02-12
Abstract: PROBLEM TO BE SOLVED: To provide a stable high withstand voltage which is not easily influenced by variation of manufacturing process and the characteristics of a protection film, by making a second conductivity type semiconductor layer contacting a gate metal have a concentration and a thickness which permit a neutral region to be formed when there is no potential difference between a gate electrode and a drain electrode. SOLUTION: On a semi-insulating GaAs substrate 11, a p-GaAs layer 14 which contacts a gate metal 17 is formed between a source and a drain. The p-GaAs layer 14 has a concentration and a thickness which permit neutralization, under the condition where no voltage is applied between the gate metal 17 and the drain. Therefore, the neutral p-GaAs layer 14 close to the gate has the same potential as that of the gate metal 17, and serves as the gate of a cascode connecting FET used for MOSFET withstand voltage design. The gate potential of a FET can be controlled without being directly influenced by the surface level. Thus, a stable high withstand voltage which is not easily influenced by variation of manufacturing process and the characteristics of a protection film is obtained.

Filed: 1989-02-09
Abstract: PURPOSE:To standardize a main reflecting mirror, to improve the accuracy and to reduce the cost by forming the surface of a main reflecting mirror to be a paraboloid of revolution and applying phase control to a sub reflecting mirror and amplitude control to a primary radiator so that desired amplitude and phase distributions are obtained on an antenna aperture with the sub reflecting mirror and the primary radiator.

Then the phase is controlled with a sub reflecting mirror 21 whose mirror surface is corrected and the amplitude is controlled with an amplitude controlled type primary radiator 31. The primary radiator 31 for amplitude control and the sub reflecting mirror 21 for phase control are combined with each other. Thus, a required antenna characteristic such as uniform distribution and taper distribution able to realize a high gain characteristic and a low side lobe characteristic is obtained without applying mirror surface correction to the main reflecting mirror. Thus, the main reflecting mirror is standardized and the economical main reflecting mirror with high accuracy is obtained.
