Title: Pilot operation pressure control valve
Inventor: YAMAMOTO KOHEI
IPC: F16K17/10
Filed: 1993-01-29
Abstract: PURPOSE:To provide a pilot operation pressure valve, by which favorable pressure control can be carried out for a long time, by reducing main valve body operation failure caused by invasion of a foreign matter into a pressure fluid to be controlled. CONSTITUTION:Both ends of a main valve body 6, which is fitted inside a main body 1 freely slidingly, restrictively communicates with each other via a throttle hole 9, while a pressure fluid is let flow freely to the low pressure side by a pilot valve body 14 after flowing through the throttle hole 9, and a clearance H, whose size is smaller than that of the diameter D of the throttle hole 9, is formed in a flow path in front of the throttle hole 9. A foreign matter catching part, 12, in which the clearance H cross section area is provided larger than the cross section area of the throttle hole 9, communicates with the throttle hole 9, so that a foreign matter, which contaminates the pressure fluid to be controlled and is large enough to block the throttle hole 9, is surely caught by the clearance H of the foreign matter catching part 12.

Title: Reaming method for hollow billet
Inventor: AKIYAMA MASAYOSHI
IPC: B21J5/10
Filed: 1987-02-17
Abstract: PURPOSE:To improve the penetration thereafter without increasing stages and to enhance the material yield by press-fitting a reaming plug into the hollow billet supported by ascending with the insertion of a spreading plug from a shearing hole side and making a shearing hole side in the state of the diameter spreading state toward the terminal. CONSTITUTION:A spreading plug 3 is inserted from a shearing 1b hole side for the hollow billet 2 inserted into a container 1 to support the hollow billet 2 by its ascent. The billet 2 is enlarged at its diameter by press-fitting a reaming plug 4 in this state to make the shearing 1b side billet 2 in the state of enlarging its diameter toward the terminal by the spreading plug 3 as well. When the spreading plug 3 is withdrawn and the reaming plug 4 is penetrated by its press-fitting, the push-up of the diameter increasing billet close to the pressure fit completion time is facilitated to reduce the discard 6 at the shearing 1b punch through time of the reaming plug 4. The reaming is therefore improved and the material yield can be enhanced. The working is improved by inputting the lubricant 5 of a glass powder, etc., on the spreading plug 3.

Abstract: PURPOSE:To realize a large area of an amorphous or crystalline deposited film containing carbon while improving its various characteristics, speed of film formation and reproducibility and making quality of the film uniform by a method wherein particular activated seeds which are activated separately beforehand in spaces different from a film forming space are brought into chemical reaction. CONSTITUTION:Instead of creating plasma in a film forming space where a deposited film 10 consisting of an intermediate layer 12 and a photosensitive layer 13 is formed, an activated seed produced by decomposing a compound containing carbon and halogen and an activated seed produced from a carbon containing compound for film formation are introduced into the film forming space. By applying heat energy to those seeds, chemical interaction is created or promoted and amplified. The deposited film 10 formed with this method does not get harmful influence from etching, abnormal discharge or the like. Light energy is applied all over a substrate 11 by a suitable optical system to form the deposited film 10.

Title: Method and system for retrieving information and recording medium recording information retrieval processing program
Inventor: TANAKA TOSHIO
IPC: G06F12/00
Filed: 1999-02-12
Abstract: PROBLEM TO BE SOLVED: To enable any server to request retrieval and to efficiently retrieve suitable information in an information retrieving system including plural servers in a network. SOLUTION: When a retrieval request is outputted from a client to a certain server, the server (called as a main server) receiving the request prepares a retrieving condition corresponding to the server (S1) and checks whether information suitable for the retrieving request is stored in its own cache memory or not in each retrieving request (S2, S3). When suitable information exists in the cache memory, the information is outputted as a retrieved result, and when there is no suitable information, the server retrieves its own information data base when the retrieving condition is for the server itself (S5, S6) and stores the retrieved result in the cache memory. When the server itself is not an object server, the server sends the retrieving condition to another server (called as a slave server), receives its retrieving result and stores the received result in its own cache memory (S8).

Title: Da converter
Inventor: ONODA HIROSHI
IPC: H03M1/82
Filed: 1990-02-16
Abstract: PURPOSE:To improve output stability without giving a delay to a settling time by increasing a pulse width at the initial state of a sample-and-hold signal so as to shorten a charging time and decreasing the pulse width every time the number of generated pulses is increased. CONSTITUTION:When a digital signal is set by an input device, a sample-and- hold pulse generator 11 generates a pulse signal whose pulse width is large (tau1) at first but decreasing gradually as tau2, tau3, tau4 and constant at tau5 and thereafter. The pulse width of a pulse signal SG1 is large at the start of the input of the digital signal and a charging time to a hold capacitor C2 is long, then the time when the voltage across the hold capacitor C2 is short and then the settling time is small. Moreover, since the pulse width of the pulse signal SG1 is small, the output stability is improved.
