Title: Actuator for optical head
Inventor: NAKAE NOBUYUKI
IPC: G11B7/09
Filed: 1988-02-27
Abstract: PURPOSE:To eliminate an adjusting work and to reduce the number of parts by fitting a focusing coil and a tracking coil in the inside of an objective lens holder, and providing one magnet facing to the respective coils. CONSTITUTION:A focusing coil 8 is set in a magnetic field by a magnet 10 and when a servo current flows to the coil 8, driving force in a direction F0 is operated. Then, an objective lens holder 2 and an objective lens 1 are driven in the direction F0 and focusing control is executed. When the servo current flows to tracking coils 9a and 9b in the magnetic field by the magnet 10, the current of a component, which is parallel with the optical axis of the coils 9a and 9b, affects the magnetic field generating the driving force in a Tr direction. Thus, the holder 2 and lens 1 are driven in the Tr direction.

Title: Image forming apparatus
Inventor: NAGAI ETSUO
IPC: B41J2/525
Filed: 1996-02-07
Abstract: PROBLEM TO BE SOLVED: To provide an image forming apparatus capable of efficiently obtaining highly accurate images. SOLUTION: A photosensitive body 12 is irradiated with a laser beam from an LD portion 10, with the intensity of the laser beam adjusted by a resist adjusting circuit 11. The value of the current flowing through the photosensitive body 12 by the laser irradiation is measured by a current sense 13. The starting positions A1, A2, A3 of writing an image on the photosensitive body 12 are administered by address or timing pulses 0000, 0010, 0100. By measuring and adjusting the current value flowing through the photosensitive body 12 with the current sense 13 at the time of initializing, the starting positions A1, A2, A3 of writing an image on the photosensitive body 12 are adjusted so as to prevent color misregistration. Fine adjustment of writing positions can be achieved without a mechanical procedure.

IPC: G01K7/00
Filed: 1997-02-28
Abstract: PROBLEM TO BE SOLVED: To accurately measure the body temperature of a person to take the temperature with excellent reproducibility without being affected by an outdoor temperature regardless of the individual difference of the person to take the temperature. SOLUTION: Corresponding to whether the person to take the temperature is an adult or a child, an operation part 22 is slid and moved, an infrared ray sensor 20 is brought closer or separated to/from the rear end face 11b of a light guiding tube 11 and the light receiving angle of the infrared ray sensor 20 is adjusted. To put it concretely, the light receiving angle is relatively wide in the case that the person to take the temperature is the adult and it is changed so as to be relatively narrow in the case that he/she is the child inversely.  Thus, only infrared rays radiated from the tympanum and the periphery are received at the light receiving part 21 of the infrared ray sensor 20 at the appropriate receiving angle at all times, the temperature is obtained from the infrared ray amount and the temperature is displayed on a body temperature display part as the body temperature of the person to take the temperature.

Title: Optical pickup device
Inventor: HONDA SHUICHI
IPC: G11B7/085
Filed: 1991-02-20
Abstract: PURPOSE:To reduce the size of the carriage of a optical pickup device. CONSTITUTION:By arranging split focusing coils 21 and 22 as well as 23 and 24 at a holder 25 holding an objective lens 5 so that they can slightly overlap with each other, the dimension of the respective focusing coils 21, 22, 23 and 24 in their winding direction is reduced.

IPC: B21B37/18
Filed: 1996-03-04
Abstract: PROBLEM TO BE SOLVED: To obtain good thickness from the tip part of a material to be rolled by predicting thickness deviation on the outlet side of each stand with high accuracy and correcting screw-down location based on this predicted value before the material to be rolled is bitten at the time of passing the material to be rolled through in hot finish rolling.

Filed: 1998-02-27
Abstract: PROBLEM TO BE SOLVED: To provide a kerosene vaporizer which enables a uniform vaporization on the entire region of a wick without causing a tar clogging in an oil inlet opening of a carburetor body. SOLUTION: A kerosene vaporizer is constructed such that a heat receiving bar is disposed at a position between a cap and a nozzle of a carburetor body while being exposed to the combustion flame of the burner for recovering combustion heat. In such a kerosene vaporizer, the cap 3 is made of a stainless steel which has poor thermal conductivity, and an oil inlet opening 6 for introducing kerosene is opened at the cap 3, a wick 5 made of a foamed metal which has an excellent kerosene suction ability is disposed between the carburetor body 1 and a heat generating body 4 and hence, the supplied kerosene is sucked into the entire region of the wick 5 without being dwelled at the bottom of the inside of the carburetor, so that the moderate vaporization is performed at the entire region of the wick. Accordingly, the generation of tar at the oil inlet opening and the wick can be restricted so that the durability of the carburetor against clogging by tar is further enhanced.

IPC: C21D1/76
Filed: 1984-03-08
Abstract: PURPOSE:To reduce red rusting and lowering of adhesiveness of a blackened film by throwing steel plate parts into a steam atmosphere under a high temperature while permuting the steam atmosphere into an inert gas atmosphere on the way to temperature rise or temperature holding.
