Title: Back projection type screen and its production
Inventor: YAMAGUCHI HIROSHI
IPC: G03B21/56
Filed: 1996-08-29
Abstract: PROBLEM TO BE SOLVED: To make it possible to hold a film-like screen sheet with extremely high flatness, to drastically decrease double images, to improve resolving power and to decrease moires without the occurrence of light loss as in the case this screen sheet is held by using a transparent plate. SOLUTION: The film-like screen sheet 4 is constructed by fixing the film-like screen sheet to a supporting member 7 having relatively high rigidity in the peripheral part on the outer side of an effective region having an optical function. The process for production consists in clamping the periphery of the film- like screen sheet 4 formed with the optical function part by a photosensitive resin to a transparent resin film and adhering the supporting member 7 in the state of applying tension thereon. As an effect, the practicable use of the film-like screen sheet having the high flatness and having no wrinkles and deflection is made possible. The drastic decrease of the double images is made possible when this sheet is used for a Fresnel lens sheet.  The back reflection type screen which has the excellent resolving power, is slight in the generation of the moires and has the high image display grade is embodied when the sheet is used for a lenticular lens sheet.

Title: Oil feeder of bevel gear type speed reduction gear
Inventor: TACHIBANA TOSHIHIKO
IPC: F16H1/14
Filed: 1984-10-29
Abstract: PURPOSE:To prevent abrasion of a rolling surface by rotating a pressure element together with an oil feed element while revolving on its axis, and always oiling from an oiling member in an oil feed element to a portion rotating on its axis. CONSTITUTION:An oscillating bevel gear 2 engaged with a stationary bevel gear 1 has the back of an engagement portion pressed by a pressure element rotating round the gear while rotating on its axis to move the engagement portion in such a manner as to rotate round the gear. Therefore, the gear 2 torsionally oscillates and interlocks with the stationary bevel gear 1 to be decreased in speed. By the speed reducing interlocking operation, the pressure element 3 is caused to rotate round the gear and on its axis. The rotating portion of the pressure element 3 is subjected to oiling of lubricating oil by an oiling member 4 rotating round the gear together with the pressure member 3, so that abrasion is hard to occur and the rotation is smoothly kept up.

Title: Method for mounting microlens array sheet
Inventor: UCHIDA TETSUO
IPC: G02F1/1335
Filed: 1994-08-29
Abstract: PURPOSE:To increase a visual field angle by bringing the peak part regions of the projecting parts of the rugged surface of the first material layer of micro-unit lenses into tight contact with the surface of a liquid crystal cell. CONSTITUTION:The peak part regions 11 of the projecting parts of the rugged surface of the first material layer 1 of a microlens array sheet 52 are brought into tight contact with the surface 10 of the liquid crystal cell 51, by which a part of the first material layer 1 is eventually brought into contact with the surface 10 of the liquid crystal cell having a relatively small difference in refractive index and the prescribed critical reflection condition is destroyed in a part of the retroreflection route on the lens surface and, therefore, the external light infiltrating the inside of the microlens array sheet 52 is guided into the liquid crystal cell 51 without making retroreflection. The retroreflection on the lens surface is thus suppressed. Namely, the disadvantage of the narrow visual field angle of the liquid crystal display is overcome by the extremely simple constitution of merely providing the observation surface side of the liquid crystal cell 51 with the microlens array, by which the good display grade is eventually obtd. in the observation direction of a wide range. The display grade which compares favorably with other display systems, such as CRT system, is obtd.

Title: Motor for driving disk
Inventor: SAKANO HIROMICHI
IPC: G11B19/20
Filed: 1994-08-30
Abstract: PURPOSE: To form a motor to a thinner type and to make torque larger and a cost lower by detecting the magnetic flux of a magnet for a field via a magnetic material outside the range of the direct magnetic field and forming the magnetic material thinner than a Hall element. CONSTITUTION: The magnetic flux is generated in the magnet 5 for the field when electric power is supplied to the motor for driving a disk. This magnetic flux crosses a printed coil 3. At this time, the magnetic flux is transmitted to the position outside the range of the direct magnetic field of the magnet 5 from this position, i.e., the position on the outer side of the rotor 2 or the bracket 1, by which the intensity of the magnetic flux is detected by the Hall element 11 mounted in this part. The signal detected by the element 11 is transmitted to a control circuit, by which the printed coil 3 is energized in the order determined in accordance with the this signal. The magnetic flux from the magnet 5 crosses the coil 3 at the time when the magnetic flux flows toward an auxiliary yoke 6, by which the rotor 2 is rotated and the disk 10 mounted at the rotor 2 is rotated integrally with the rotor 2.

Title: Non-contact type surface potential detecting apparatus
Inventor: KUMADA AKIRA
IPC: G03G15/00
Filed: 1983-12-02
Abstract: PURPOSE:To enhance an SN ratio by taking out the change portion in charge induced in a detection electrode, by mechanicaly vibrating the detection electrode in parallel to electric line of force incident to the detection electrode to make the capacity between a surface to be detected and the detection electrode variable. CONSTITUTION:When high voltage is applied to a surface 1 to be detected, charge corresponding to the capacity of a capacitor formed by the surface 1 to be detected and a detection electrode 2 is induced in the detection electrode 2 opposed to the surface 1 to be detected. Herein, because mechanical vibration is imparted to a piezoelectric tuning fork main body 4 to the detection electrode 2, the distance between the surface 7 to be detected and the detection electrode changes and the capacity of the air capacitor constituted between the surface 1 to be detected and the detection electrode 2 is changed with the change in said capacity. Therefore, the charge induced in the detection electrode 2 is also changed. This change portion in the charge flows to a resistor 8 and voltage corresponding to the resistance value of the resistor 8, high voltage applied to the surface 1 to be detected and mechanical vibration added to the detection electrode 2 is generated. Detected voltage receives impedance conversion due to FET9.

Then the price of the commodity is calculated by means of an arithmetic means 8 from the weight rounded by the means 7 and the unit price in the memory 1 and stored in a price memory 3. Thereafter, a price display controlling means 9 displays the price only in a displaying section 4. Therefore, the efficiency of the weighing instrument can be improved.

Title: Picture communication equipment
Inventor: NISHII TERUYUKI
IPC: H04N1/32
Filed: 1989-09-06
Abstract: PURPOSE:To avoid the transmission to a wrong opposite station by collating plural sets of identification information acquired at communication with corresponding identification information sets stored in a storage means and permitting polling transmission only when they are all coincident with each other. CONSTITUTION:An ID code is a password in 4 digits or so decided by each user and stored in a memory area M of a RAM 3 in advance. Moreover, a telephone number of an opposite station allowing polling transmission at the polling transmission side is stored in the memory area M. Then plural sets of identification information such as an ID code and a telephone number are collated to decide the propriety of polling transmission. Thus, the possibility of coincidence of the identification information by chance and the transmission of a picture data to a wrong opposite station is remarkably reduced and polling transmission is applied only to an intended opposite station surely.
