Title: Flowmeter
Inventor: UEKI KOICHI
IPC: G01F1/66
Filed: 1997-05-21
Abstract: PROBLEM TO BE SOLVED: To obtain a flowmeter by which the air or the like mixed in its installation can be detected in a measurement by a method wherein data values in propagation times in which signals are measured by two receiving means and a data value in the propagation time by various stored mediums are compared with each other so as to be judged. SOLUTION: A first flow-velocity sensing means 10 and a second flow-velocity sensing means 11 are attached inside a pipe 1 so as to be faced. A first receiving means 12 which is connected to the first flow-velocity sensing means 10 receives a signal from a second transmitting means 15. The propagation time which elapses until the signal is received after its transmission is started is found. A second receiving means 13 receives a signal from a first transmitting means 14, and its propagation time is found in the same manner. A propagation-time-difference measuring means 16 computes a propagation-time difference on the basis of signals from the flow- velocity sensing means 10, 11 which are faced, and a flow-rate computing means 17 finds a flow rate on the basis of it.  On the other hand, a propagation-time value in various mediums stored by a propagation-time storage means 18 and propagation time values obtained by the respective receiving means 12, 13 are compared by a medium judgment means 19 so as to be judged. Whether or not a foreign matter is mixed with a medium to be measured is judged.

Abstract: PURPOSE:To step up durability, safety and responsiveness, by installing a normally opened valve, which is opened by pressing force from the outside and expands its volume for decompression, in position between a master cylinder and a braking device, in case of an antilock device. CONSTITUTION:When a second solenoid valve 22 is closed of its circuit as a first solenoid valve 19 is left opened intact, discharged oil out of a pump 18 is fed to an oil chamber C, causing pressing force from the side of the oil chamber C to act on a decay piston 17, and the pressing force from the outside is given to a decay rod 15. With strength of this pressing force, interception of a route ranging from a master cylinder 2 to a braking device 4 and decompression in brake oil pressure take place inside a brake oil pressure control valve 6. Next, when the solenoid valve 19 is closed as the solenoid valve 22 is left closed intact, hydraulic pressure is kept constant whereby the hydraulic pressure can be decompressed and closed with only making the solenoid valve 22 open, permitting of keeping the pressure, thus a decrease in oil quantity inside the oil chamber C causes the brake oil pressure to produce its repressurizing.

Title: Contact printing method
Inventor: TANAKA KAZUHIRO
IPC: H01L21/027
Filed: 1980-09-23
Abstract: PURPOSE:To facilitate the separation after a contact printing by lowering the surface free energy of a substrate coated with photosensitive resin and contact printing it. CONSTITUTION:An emulsion mask is covered on a side to be cntact printed, and Cr is covered on a glass substrate at the side to be printed as a plate coated with photoresist. The plate to be covered with the resist is dipped in developer for approx. 30sec is then washed with pure water, and is then dried with N2. Even if the treated plate is contact printed, the separation after the printing can be facilitated so that the resist do not separated. When it is developed after the exposure, a resist pattern of high accuracy can be obtained in the same manner as the conventional one. When it thus dipped in the developer before the exposure, uneven surface is produced in molecular level to substantially lower the surface free energy. Since uniform and low surface energy level is formed on the entire surface of the plate, another mutual action is not induced newly in contact printing. In order to lower the surface free energy, it may additionally be dipped in specific solution or may also be injected with ions to the resist.

Abstract: PROBLEM TO BE SOLVED: To prevent an erroneous assumption of an operation state different from a normal operation state during reduction control by a method wherein, based on a signal from a control means to reduce the generation of unburnt gas, display under operation of reduction control of the unburnt gas is performed. SOLUTION: When control of ignition (or fire extinguishment) is started, a deodorization display part 9a of a display apparatus 9 is lighted ON. This display is brought into visibility by a user, and it is recognized that operation during control of ignition (fire extinguishment) in a state different from normal operation is not abnormal. Further, even when, during ignition (fire extinguishment) control, operation of a stop of operation (or reoperation) is effected, operation to a stop of operation (reoperation) is blocked during a time in which control is completed. That is, a condition of control of ignition (fire extinguishment) in a special operation state is maintained until control is completed. This constitution suppresses the generation of unburnt gas, i.e., the generation of a smell.
