Title: Testing and measuring system for semiconductor device
Inventor: KARASAWA WATARU
IPC: G01R31/26
Filed: 1986-10-28
Abstract: PURPOSE:To attain a remarkable rise in a testing and measuring system availability rate by a method wherein comparison is effected between the yield of semiconductor devices and a predetermined value and the outcome of the comparison is used to mark fault semiconductor devices. CONSTITUTION:Upon completion of a measuring process, comparison is made in a comparator 2e between a predetermined number of good devices supplied beforehand from an input section 2g and the number of good devices stored in a memory section 2d. When the number of devices judged to be good is larger then the predetermined number of good devices, marking is provided on the faulty semiconductor devices memorized in the memory section 2d, which is accomplished in a marking section 2f. When the number of devices judged to be good is equal to or smaller than the predetermined number, no marking is provided in the marking section 2f, but printing is accomplished indicating poor quality. A wafer 1 is then unloaded into a specified carrier. This method eliminates the need for marking for a semiconductor wafer 1 mounted with a number of faultly semiconductor devices, which improves on a semiconductor device testing and measuring system in its availability rate.

Abstract: PURPOSE:To measure the surface flatness of a specimen to be measured in a non-contact state, by detecting the pitch of a lattice image on the basis of the conversion signal from a photoelectric converting unit and calculating the standard deviation f the pitch according to a specific formula. CONSTITUTION:The light from a light source 1 becomes uniform intensity distribution by a diffusion plate 2 to illuminate a lattice 3.

Title: Artificial gathering-place for fish
Inventor: SHIOTANI MASAO
IPC: A01K61/00
Filed: 1987-10-13
Abstract: PURPOSE:To obtain an artificial fish gathering-place capable of producing remarkable effects as improvement in fishing ground, by forming through-holes in the shape of a maze in a fish gathering-place body and constituting the fish gathering-place so as to impart a great change to generated eddies while enhancing escape effects of fishes. CONSTITUTION:Fishes go in and out through-holes 2 formed in the shape of a maze, acting as a fish gathering-place. Seawater entering the through-holes 2 is passed through the holes 2 and discharged from others. During that time, seawater enters the holes 2 to be decelerated, conversely accelerated or various changes are caused according the shape of the holes 2 in a process for passing through the holes 2, resulting in formation of eddies near the fish gathering-place 1 in entrance and exit from the holes 2. If the body 1 is constituted of combination of divided pieces 3, all the pieces 3 are laminated in the initial stage. Fisheries plants then adhere to the surface of the pieces 3. Since the adhesion ratio is the best in the first year, one of the pieces 3 is moved along engaging parts when one year passes after the use. Novel surfaces which have been closely adhered are exposed by this movement and fisheries plants newly grow thick on the surfaces. Thereby effects as a fish gathering-place are enhanced.

Abstract: PURPOSE:To enhance the responsiveness of a hydraulic circuit by connecting the hydraulic circuit for leading loaded pressure oil to a switching valve, which controls the hydraulic pump capacity in the direction of decrease by pump discharge pressure and in the direction of increase by load pressure, to a tank through an unloading valve which shuts off the oil by load pressure and allows to pass through by pump discharge pressure. CONSTITUTION:A branch circuit 26 connected to a hydraulic circuit 23 for connecting a shuttle valve 21 to a pressure receiving portion 14a of the switching valve 14 is connected to and shut off from a tank 28 through an unloading valve 27. The unloading valve 27 is positioned at a connecting position I or a shutting-off positions II depending on the difference in pressure at 1st and 2nd pressure receiving portions 27a and 27b, and at the shutting-off position II by a spring 29. The 1st pressure receiving portion 27a is connected to a discharge line 10a and the 2nd one is connected to the branch circuit 26. Accordingly, when a control valve 15 is switched over from a neutral position to a pressure oil feeding position, the unloading valve 27 is positioned to the shutting-off position II and loaded pressure oil does not flow out to the tank 28. Thus, the responsiveness is enhanced and the driving noise is not produced from a hydraulic pump 10, whereby an operator will not be affected.
