Title: Transducer
Inventor: ITAGAKI TADASHI
IPC: H04R9/00
Filed: 1984-06-29
Abstract: PURPOSE:To set the vibration characteristic securely and easily and to obtain the balanced vibration without deviation in vibration by vibrating a vibrator having a balance weight function supported by a dumper by drive force generated on a moving coil. CONSTITUTION:A moving coil 17 is positioned in a magnetic gap of a magnetic circuit consisting of a center pole 13, bottom plate 14, magnet 15 and top plate 16, and an end of a bobbin 18 where the moving coil 17 is wound is fixed to a vibrator 19 made of metal. The vibrator 19 is fitted to a casing 1 by a dumper 20, and its fitting position is on a flat surface including a center of gravity of the vibrator 19 and supports the center of the vibration. When a signal current is supplied to the moving coil 17, drive force is produced between the magnetic circuit and the moving coil 17, whereby the vibration is transmitted to the vibrator 19 and transferred to a casing 11 through the dumper 20. Since the magnetic circuit is fitted to a casing 11, the vibration is free from weight and shape of the magnetic circuit.

Filed: 1981-08-29
Abstract: An assembly of storage units (6,7) which are mainly used in offices for a well-ordered filing of documents, will appear to be too small after some time. If one adds a column of units, this will have a lock of its own. The invention provides an assembly whereof some or all units of some or all columns can be locked by one locking mechanism. In the case of storage units consisting of a case with inwardly directed flanges cooperating with side flanges of drawers, each column has a converting mechanism (11) which is not only responsible for the up and down movements of lock rods but also for the reciprocating movement of a coupling rod (12) whose other end can cooperate with the converting mechanism of adjacent columns.

Title: Control device for oil pressure of lock-up clutch
Inventor: ASAYAMA YOSHIO
IPC: B60W10/11
Filed: 1987-05-30
Abstract: PURPOSE:To improve acceleration at the time of speed change by providing a valve for discharging a pressure oil in the defined oil chamber in a modulation valve to a drain, lowering a lock-up oil pressure to a defined pressure at the time of speed change and, after maintaining this oil pressure for a defined time, gradually increasing the oil pressure. CONSTITUTION:At the time of speed change a lock-up modulation valve 14 is opened by a controller 40 and oil from a hydraulic pump 5 is fed to a lock-up clutch 1 while oil in the oil chamber of the valve 14 is drained. As a result, at the time of speed change, the oil pressure of the lock-up clutch 1 is lowered to a defined oil pressure which is determined by the initial energizing force to a spring 23 and the other pressure receiving area of a spool and, after that, the pressure is gradually increased from the point of time when the electric command inputted into a solenoid valve 30 is discontinued. That is, at the time of speed change, the oil pressure in the lock-up clutch is lowered to a defined pressure other than zero without draining the clutch. As a result, a filling time required for filling the lock-up clutch can be eliminated.

Abstract: PURPOSE:To prevent the lowering in measuring accuracy by effectively preventing the interference of bilirubin contained in a specimen liquid, by irradiating the specimen liquid with photometric light having only quantity necessary for measurement at the time of the measurement of optical density provided so as to have a predetermined time interval. CONSTITUTION:In a method wherein a specimen liquid containing enzyme is supplied onto a dry chemical analytical element to be held to constant temp. and the coloration chemical concn. of the substance having absorption at a specific wavelength such as p-nitrophenol coloring matter (PNP) formed by chemical reaction due to enzyme is measured by a reaction speed method, when optical density is measured at each time, light is allowed to irradiate the reagent layer 5a of a chemical analysis slide 5 only for a time necessary for the measurement of the reflection chemical concn. of said reagent layer 5a, and, after the photometry at this time, irradiation is blocked by a filter 73 even during the reaction time on the reagent layer 5a until the next measurement of concn. to prevent the irradiation of the reagent layer 5a with light. By this method, the irradiation quantity of light irradiating the reagent layer is reduced and inference due to the fading of bilirubin contained in the specimen liquid can be prevented effectively.

Abstract: PURPOSE:To selectively form a protective film only on the resonator end face of a laser array by forming between the semiconductor lasers a partition of semiconductor longer than the resonator length of the semiconductor lasers, thereby to shield part of the particles beam of the protective film having a strong directivity. CONSTITUTION:Between two semiconductor lasers in addition to two pairs of resonator surfaces, a projecting partition 19 of semiconductor which is longer than the resonator length by 45mum is formed.
