Title: Resting device in mirror driving mechanism for camera
Inventor: YAMAMOTO MASARU
IPC: G03B19/12
Filed: 1988-10-31
Abstract: PURPOSE:To contrive the release of a shock of a mirror by using a ultrasonic motor as a driving source and controlling the stopping of the ultrasonic motor by an output from an optical detector that detects the lowering of the mirror at the predetermined position. CONSTITUTION:The mirror driving mechanism for a camera that lifts the mirror 22 by using the ultrasonic motor 21 as a driving source is provided with the optical detector 51 that detects the lowering of the mirror 22 at the predetermined position, and is constituted in such a way that the ultrasonic motor 21 is controlled to stop by the output from the detector 51 and the mirror 22 is kept rest. That is, when the mirror 22 is lowered to the predetermined position, the detector 51 detects the position and stops the ultrasonic motor 21 by the detected output. Therefore, since the static torque of the ultrasonic motor 21 is extremely high, the mirror 22 is surely rested and held at the oblique position, for example, the tilt angle 45 deg.. The shock by the mirror can therefore be released.

Abstract: PURPOSE:To produce a steel wire coil having specific hardness or above and excellent fatigue resistance at a low cost by subjecting the steel coil which is coiled to a prescribed shape at a cold or hot and contains C, Si, Mn, and Cr at a specific ratio to hardening then to low-temp. tempering. CONSTITUTION:The steel wire contg. 0.5-1.2wt% C, 0.5-2.5wt% Si, 0.5-2.0wt% Mn, and <3.0wt% Cr is coiled at cold or hot. The coil is heated to, for example, 850-950 deg.C and is subjected to oil or water hardening. The coil is thereafter tempered for about 30min at 150-360 deg.C. The steel wire is heretofore coiled after a heat treatment and is, therefore, tempered at a high temp., but if the steel wire is subjected to the above-mentioned low-temp. tempering, the hardness is 650>=Hv and the fatigue strength taua is about 60kgf/mm<2>. The steel wire consists of the inexpensive components to be incorporated therein and does not require a surface treatment; in addition, energy is economized and the cost of the product coil is reduced.

Title: Inverter circuit for illumination lamp
Inventor: WATANABE HARUO
IPC: H02M7/48
Filed: 1994-10-17
Abstract: PURPOSE: To provide a circuit with simple structure which can prevent noise generation at the time of lighting and can keep stable lighting by connecting an auxiliary inductor and a controlling coil of the inductor in series between a rectifier and a smoothing capacitor. CONSTITUTION: In the case an inductor 21 for lighting is assumed to be a primary winding of a transformer and the numbers of the turns of the inductor 21 and a control winding 21b are made the same, the waveform of the output current of a total waveform rectifier 2 becomes substantially sinusoidal waveform by on and off of a switching element 10 and thus the power factor is improved. Though the lighting operation is same as a conventional lighting by on and off of the switching element 10, high frequency current at the time of lighting is decreased due to the substantially sinusoidal waveform of the commercial input current and thus noise is hardly generated.

Title: Head mounted display device
Inventor: KOYAMA MOTOO
IPC: H04N5/64
Filed: 1996-09-27
Abstract: PROBLEM TO BE SOLVED: To obtian a device in which an electronic picture is easy to see without depending on an external picture and in which satisfactory synthetic pictures in which the external picture is made to be a background and the electronic picture is made to be forground are obtainable by locally dimming a light from the outside in order to make the background of a display picture to be observed selectively dark. SOLUTION: After an external light made to be, for example, a linearly polarized light through a polarizer 6 is locally modulated through the liquid crystal layer of an assembled member 3, it passes a semitransmission film 11. Besides, an incident absorbing light on the semitransmission film 11 through an observing optical system is reflected on the semitransmission film 11 to be synthesized with the external light transmitting the film 11. In this case, the polarization direction on the external light passed through the polarizer 6 is locally changed by the action of the liquid crystal layer. As a result, the external light in which the polarization direction is changed is dimmed through an analyzer 4.  Thus, the external picture and the electronic picture are simultaneously observed in a satisfactory state by selectively forming a dark background area as necessary at the outer side of an object and by superposing the electronic picture in the dark background area.

SOLUTION: This process for producing photoreceptor by immersing a conductive substrate 11a into the coating liquid 1 contg. an org. material, then pulling up this substrate, thereby forming at least the change generated layer and the charge transfer layer is the process for production in which the sp. gr. of the coating liquid 1 contg. the solvent for forming the charge generating layer and a charge transfer layer is smaller than the sp. gr. of the charge generating layer and the charge transfer layer.  Namely, the dust 15 having the sp. gr. larger than the sp. gr. of the coating liquid 1 settles gradually and the dust 15 intruded into the coating liquid does not adhere to the coating film any more when the conductive substrates 11a formed by cutting an aluminum pipe to a prescribed length and forming an anodically oxidized film thereon is immersed into the coating liquid 1 toward a direction V.

Title: Electrolytic ion water making apparatus
Inventor: TAKAYASU ATSUSHI
IPC: C25B9/19
Filed: 1996-09-28
Abstract: PROBLEM TO BE SOLVED: To provide an electrolytic ion water making apparatus having a new electrode structure reducing running cost in a washing process, preventing the environmental pollution caused by waste water and enhancing the safety of work environment. SOLUTION: A carbon electrode (anode 4 and cathode 5) reduced in the omission of a carbon piece is used in an electrolytic tank 1 to form electrolytic ion water free from metal contamination. A crystalline carbon electrode such as graphite molded by baking has many pores and an uneven surface. Herein, after the molded elements of the electrodes 4, 5 are formed, an amorphous carbon layer is formed on the surface thereof. Since the carbon layer is deposited up to the interiors of the surface pores of the molded elements, the mutual bonding of carbon elements is increased to make the omission of a carbon piece hard to generate. Since the surfaces of the electrodes are covered with a filter 7, even if the carbon piece is omitted, it is caught by the filter 7 and the mixing of particles with electrode ion water can be prevented.
