Title: Current tester for semiconductor device
Inventor: KIKUCHI MICHIKO
IPC: G01R31/26
Filed: 1987-04-16
Abstract: PURPOSE:To achieve a higher accuracy of testing current, by checking the attaching of a semiconductor device to be measured to and the detaching thereof therefrom a measuring jig to automatically correct leakage current of a measuring system itself at each insertion thereof. CONSTITUTION:A current measuring device 4 receives an input of an analog current measuring signal in at an output terminal of a measuring jig 2 to be converted into a digital current signal isi through a sampling ammeter 5 and supplies it to one input terminal of a memory circuit 6 and a computation circuit 7. When an IC1 to be measured is inserted into a socket 3, the IC1 being measured intercepts light of a light emitting element 9 and an insertion detection signal PD from a light receiving element 10 sensing the interception is received with a computation trigger circuit 11 to supply a trigger signal Pm to a control end of the circuit 7, which subtracts a memory signal iNi from the signal isi as correction value according to the according to the signal Pm and a difference signal idi is displayed 8. When an IC to be measured is inserted into the socket 3 after a certain time interval, a difference signal is displayed in the same sequence. Thus, leakage current is always automatically corrected by a memory signal immediately before the insertion into the socket, thereby enabling highly accurate testing of current of the semiconductor device.

Title: Silver halide photographic sensitive material
Inventor: KAWASAKI HIROSHI
IPC: G03C3/00
Filed: 1991-04-02
Abstract: PURPOSE:To prevent the generation of blocking even if the photographic sensitive material is housed in a rolled state in a cartridge by confining the surface energy of the back surface of the photosensitive material to a specific value or below. CONSTITUTION:Gelatin having high hydrophilicity is used for the binder of the outermost layer of the photographic sensitive material. Fatty acid esters having high lipophilicity are used for emulsion protective layers. The adhesion of the hydrophilic and lipophilic emulsion surfaces is more effectively prevented as the surface energy on the outermost back layer is lower. The formation of the back layer having high water-repellent and oil-repellent properties is effective. The surface energy of the back surface of the photographic material is confined to <=35erg/cm<2> for this purpose. The contact angle formed by the back surface to be the index for oil repellency and methylene iodide is specified to preferably >=50 deg., more preferably >=55 deg. and the contact angle formed by the back surface to be the index of water repellency and the water is specified to preferably >=95 deg., more preferably >=100 deg.. The generation of the blocking is obviated even if the photographic material is housed in the rolled state into the cartridge before and after development processing.

Title: Offset parabolic antenna
Inventor: URASAKI SHIYUUJI
IPC: H01Q1/12
Filed: 1983-05-30
Abstract: PURPOSE:To obtain an inexpensive and lightweight antenna by giving displacement to a primary radiator along a straight line connecting parabola focuses corresponding to the beam directions of maximum positive and negative beam deflection angles of the elevation angle direction. CONSTITUTION:When an antenna beam is set to a satellite, the antennas are installed in three areas in Japan, i.e., the north, center and south parts respectively. The rough tracking of the direction El is performed by selecting only three of five attachment screws 14. While the rough tracking of the direction Az is carried out by means of an Az axis revolving mechanism 13 having a less degree of production precision. The fine tracking is performed by giving displacement to a horn 1, a circular polarized wave generator 17, a down-converter 18 and an El deflecting shift plate 20 which are unified together on an El deflecting fixed plate 19 which is fixed to an El switching attachment metallic parts 12 via a primary radiator system supporting structure 16. In this case, focuses Fp and Fm of an offset parabola 11 corresponding to + or -3.5 deg. are obtained with the maximum beam deflecting angle Hs set at 3.5 deg.. Thus above-mentioned unified parts have displacement along straight lines Ep and Em.

Title: Method and device for rounding groove edge of plate
Inventor: HAMADA MASARU
IPC: B24B21/16
Filed: 1986-04-24
Abstract: PURPOSE:To enable chamfering of constant quality without changing length and angle of chamfering according to changing thickness of the grinder belt by holding a plate-shaped work in a certain constant attitude and moving the corner for a certain distance along the grinder belt in the condition being pressed to the grinding surface. CONSTITUTION:Side wall 21 of a groove holds a pressing piece 18 in a certain attitude inclined a certain angle theta to the grinding surface of a grinder belt 136, and presses the corner to the grinding surface and moves for a certain distance for performing intended chamfering. Therefore, the margin is controlled by pressure and moving distance, and these factors are free of influence even though abrasive grains on the belt fall off to cause change in the thickness. Accordingly the chamfering length and angle do not change with changing thickness of the belt 136 to allow chamfering of constant quality at all times. The belt 136 is fed at a constant low speed, so that the chamfering accuracy will not be impaired by surface dullness.
