Title: Semiconductor device with heat sink
Inventor: YOSHIMIZU MAKOTO
IPC: H01L23/29
Filed: 1984-01-13
Abstract: PURPOSE:To prevent a contact accident between a heat sink and a lead section by positioning the bent section of the heat sink on the side inner than package width. CONSTITUTION:In a semiconductor device to which a heat sink 1 is mounted, two sections 7, 8 of bent sections 6-9 at four positions in the heat sink 1 are formed on the sides inner than the extensions a-a' and b-b' of parallel two sides representing the width of a package 2. According to such constitution, even when the heat sink 1 is intended to be bent in the theta direction by external force, the heat sink 1 is brought into contact with the end surface of the package 2 before it is brought into contact with leads 3 and is not bent at an angle of theta or more because the heat sink 1 is bent at the bending sections 7, 8. Consequently, contact accidents among the heat sink and the leads can be prevented.

Title: Passive non-heat transfer property in optics
Inventor: JIYOSEFU EFU BOOCHIYAADO
IPC: G02B7/02
Filed: 1995-01-13
Abstract: PURPOSE: To provide a method capable of independently executing temperature compensatsion and color compensation to prevent the focus of an optical system to be used in an infrared area from being shifted due to temperature. CONSTITUTION: When two lens materials 9, 11 having almost equal Abbe numbers and substantially different temperature coefficients of refractive indexes are selected, a double lens optically set up to passive heat non-conductivity is obtained. The power ratio of both the lens materials 9, 11 is designed so as to apply required passive heat non-conductivity. A diffraction surface 13 is formed on either one of the lens elements 9, 11 to compensate chromatic aberration. Since the Abbe numbers of both the materials 9, 11 are almost equal, color correction is not almost changed due to temperature. Consequently the power ratio of the lens elements is designed so as to control the focal distance of the double lens clue to temperature independently of color compensation.

Abstract: PURPOSE:To improve the print quality of an offset rotary press and also simplify the structure so that the feed of wetting water becomes stable. CONSTITUTION:Compressed air is supplied to a wetting water tank 16a and thereby the interior of the wetting tank 16a is pressurized. In addition, a solenoid valve for wetting water 10a and a solenoid valve for compressed air 10b are operated using a solenoid valve control device 12 and at the same time, a pressurized wetting water 16b is ejected to each cubic body 7 through each nozzle 6 from the wetting water tank 16a so that the wetting water 16b becomes fine droplets. Further, the fine droplets of the wetting water 16b are sprayed in the form of mist to a roller 5 through each slit spray nozzle 13 provided on the front of spray cover 8. Subsequently the mist lands on the roller 5. In addition, this wetting water 16b is transferred to a watering roller 4 and then to the plate 2 of a plate cylinder 1 so that a watery film is formed on the plate 2 to prevent ink from sticking to the non-image line part of the plate 2. The wetting water of large grain diameter which has not turned to fine particles even after running into the cubic body 7 is discharged to an area outside the wetting device through a drain pipe 9 on the spray cover 6.

IPC: A45D40/00
Filed: 1994-01-21
Abstract: PURPOSE:To enable mutual positioning easily and accurately in the inserting and mounting of a tray into the body of a container automatically using a positioning jig. CONSTITUTION:A retaining part is so arranged to allow the insertion and retaining of a protrusion 43 of a tray 40 into a tray positioning jig 45. On the other hand, the side of an inner cylinder body 11 is cut longer vertically to form a cut recess 23 allowed to be inserted and retained into an inner cylinder body positioning jig 35 as retaining part. The end part 24 of the cut recess 23 is cut being tapered, which allows the positioning of the body of a container and the tray thereby achieving an automatic assembling accurately and easily. The positioning can be stabilized by securing an engaged part with the positioning jig longer. This also enables the simplifying of the structure of the parts and the positioning jig. Thus, as the end part of the cut recess is formed being tapered, insertion is possible through the end part thereby improving workability very much.
