Title: Exposure controller for camera
Inventor: FUJINO AKIHIKO
IPC: G03B7/16
Filed: 1986-11-07
Abstract: PURPOSE:To obtain desired exposure corresponding to a switched photographic mode by re-storing a light measured value suitable to a specified photographic mode if an AE lock is already made when the switching of photographic modes is specified. CONSTITUTION:A photographic lens 19 and an electronic flash device 20 are mounted detachably on a camera body 1. A light measurement part 13 is equipped with a photodetecting element 16 for averaged light measurement and a photodetecting element 17 for spot light measurement and its light measurement output is sent to a microcomputer 11. Switches So, Su, Sd, and Sa are operated with a main switch 2, an up key 4, a down key 5, and an AE lock switch 6 respectively. The camera has the natural light photographic mode and flash light photographic mode and when the flash device 20 is mounted, the flash light photographic mode is selected. If the AE lock is already made when the switching of photographic modes is selected, the microcomputer 11 re-stores a light measured value suitable to the specified photographic mode. Thus, an exposure control part 14 performs exposure control according to the switched photographic mode.

Title: Traverse drum
Inventor: OTOJIMA HIRAO
IPC: B65H54/48
Filed: 1989-10-16
Abstract: PURPOSE:To wind a thread in such a manner that release tension is never fluctuated between upward and downward releases of the thread by differentiating wind number between right-hand and left-hand traverses in a thread guide channel on a drum circumferential surface to increase the difference. CONSTITUTION:In a traverse drum 1, right-hand and left-hand traverse wind numbers are differed to each other to set their difference large. Therefore, when a package 7 wound by this traverse drum 1 is fed to a double twisting machine, and a thread 8 is released in the axial direction of the package 7, the release tension at the time of downward release of the package thread is reduced, causing no end down. Further, the difference with the release tension at the time of upward release is reduced, and tension fluctuation is minimized.

IPC: F42B10/64
Filed: 1989-10-14
Abstract: PURPOSE:To prevent the occurrence of high aerodynamical interference between a front and a rear wing by method wherein, instead of a front wing the steering angle of which is changed, a front wing axially slid by means of a drive device located in a fuselage and a small wing the steering angle of which is variable and which is positioned in a nose part are provided. CONSTITUTION:Instead of a conventional front wing which flies as a steering angle is changed, a front wing 3 flying as it is longitudinally slid is used. Before the starting of guide, the front wing 3 is positioned in the vicinity of the rear end of a front wing longitudinal guide rail 10, and a small wing 4 is brought into a state in which no steering angle is provided. After the starting of induction, the small wing 4 is in a state, in which a steering angle is provided, by means of a small wing drive device 9. By means of a control command signal generated from a control command device 6, the front wing 3 is moved by a necessary distance through a front wing longitudinal drive shaft 7 by a longitudinal driven device 5. This constitution provides a wide range of the angle of attack of an airframe without being limited by the angle of stall of the front wing 3, and enables execution of steering without the occurrence of high aerodynamical interference between the front wing 3 and the rear wing.

Title: Method for hot-working continuously cast slab and steel ingot
Inventor: YAMAKAWA SHINICHIRO
IPC: B21B1/26
Filed: 1992-09-09
Abstract: PURPOSE:To reduce the development of surface flaw by quickly cooling so as to form the red-heating condition in the inner part and bainitic structure on surface structure, thereafter, heating in a furnace and executing hot-forming. CONSTITUTION:A cast slab produced by continuous casting and cut to a prescribed length or an ingot produced by using a mold, is quickly cooled so as to form the red heating condition in the inner part and he bainitic structure on the surface structure at the step cooled to the temp. higher than the Ar3 transformation point by 50-150 deg.C on the surface temp. and thereafter, heated in the furnace and the hot-forming is executed. Where, the Ar3 transformation point means the transformation temp. estimated by calculation from the component composition. In this result, when the heat of the surface recovers by heat conduction from the inner part of the red-heating condition, since AIN is uniformly and finely deposited in the bainitic structure, the deposition of AIN into austenitic grain boundary thereafter, is restrained and the surface flaw is reduced.

Abstract: PURPOSE:To make possible the mass production of a recording medium having decreased surface defects and error signals with good reproducibility by using the glass produced by a float method in which a metallic tin melt is used as a glass substrate and provided a recording layer to the surface which does not contact with the tin. CONSTITUTION:The glass produced by the float method in which the metallic tin melt is used is used for the glass substrate 11 of the recording medium 10. More specifically, fused glass 33 is cast onto the surface of the metallic tin melt 32 contained in a heat-resistant vessel 31 and is moved in one direction and pulled horizontally, by which the glass plate is produced. The recording layer 12 is formed on the surface of such glass plate on the side where the glass plate does not contact with the metallic tin melt. The surface which does not contact with the tin has therefore the decreased surface defects. The mass production of the recording medium having the decreased defects and error signals with the good reproducibility is thus made possible.

Filed: 1984-12-19
Abstract: PURPOSE:To fetch always a clear picture having good contrast by discriminating the presence and the absence of the contrast of the obtained fingerprint picture and installing a discriminating display device which informs a tested person. CONSTITUTION:The automatic discriminating device 9 automatically discriminates whether or not based upon the density distribution of the picture obtained from a converting device 4, when a finger 2 is placed at the slope 3b of a rectangular prism, the fingerprint picture is fetched into a processing device 5.

Patent JP-H1187367-A (JP)
Title: Semiconductor device
Inventor: ASANO KAZUNORI
IPC: H01L21/58
Filed: 1997-09-12
Abstract: PROBLEM TO BE SOLVED: To make the temp. distribution of a heating region uniform to avoid thermal deterioration from the central part of a finger and improve the reliability, by forming a drain source electrodes to be wide at the finger central part and narrow at the end. SOLUTION: Au platings on a drain and source electrodes 3, 2 at a central part of a heating region are broader than the periphery, i.e., the Au platings on the fingers at both ends of the heating region have the same width at their ends (in the length wise direction) and middles but the platings at the middles of the fingers disposed nearer the center of the heating region become broader. In this structure, the width of Ohmic electrodes electrically connecting the drain and source to a semiconductor substrate is const. over the heating region and hence there is no influence on electric characteristics such as withstand voltage. This makes the temp. distribution approximately uniform over the heating region to suppress the thermal deterioration of the characteristics.

The complete discharge condition of the battery concerned is sensed with the voltage measured by a voltmeter 80 in the condition that current is supplied to an end electrode 70 by a constant current source 78. When informed of complete discharge condition, the calculating device 58 starts calculating concerning the calibration. Now the mass M of the vibrating part associate with vibratory pipe 46-P, 46-N is determined, and precise measurement of capacity can be performed.
