Patent JP-H0366991-A (JP)
Title: Flow control valve device
Inventor: SUZUKI MIKIO
IPC: F16K47/02
Filed: 1989-08-03
Abstract: PURPOSE:To maintain back pressure always to the constant value so as to prevent the excessive rise of the back pressure by disposing a relief valve for controlling flow at the intermediate part of a passage for discharging oil pressure from a pressure part to an unloaded part. CONSTITUTION:Oil discharge to an unloaded oil tank T is performed after connecting a relief valve 40 formed in a housing 41 to an oil pressure passage 25 of a main body. A valve sleeve 44 is fitted and rigidly fixed into a hollow hole 42 of the housing 41. The valve sleeve 44 is provided with plural slits 44a in the radial direction as well as an axially slidable valve spool 45 inside. The valve spool 45 provided with a land part 45a and ring grooves 45b forms a variable throttle valve together with the slits 44a and the hollow hole 42. The valve 45 stops balancing with the reaction of a spring 47 according to the oil pressure from an oil pressure passage 25. Back pressure can be thereby kept constant even if the discharge flow changes, thus preventing cavitation and the excessive rise of the back pressure.

Title: Shelf unit
Inventor: YAJIMA HIDEAKI
IPC: H05K7/14
Filed: 1993-08-12
Abstract: PURPOSE:To absorb a pressing force, which is generated at the time of insertion of an intermediate package, to a back board and to prevent the generation of the deflection of the back board by a method wherein the intermediate package, which is constituted of an intermediate board, an intermediate connector, a flexible wiring board and a support fitment, is previously kept mounting in a shelf. CONSTITUTION:When a package 50 is inserted in a shelf 34, a package connector pushes a first intermediate connector, therefore an package 40 is pushed to the side of the depths of the shelf 34 and a support fitment 48 is abutted on a bumping fitment 56. In this state, when an injector 54 is made to act and the package 50 is further pushed in, the package connector is fitted in the first intermediate connector and the inserted electronic circuit package 50 is electrically connected to a back board 36 via the package 40. As a pressing force at the time of the push-in of the package 50 is absorbed by the abutment of the fitment 48 on the fitment 56, the generation of the deflection of the back board is prevented and the defective fitting of the already inserted package can be prevented from being generated.

Abstract: PURPOSE:To shorten the writing time for a cell test, a clearing action, etc., at the start carried out after turning on a power source by carrying out parallel and simultaneous writing jobs for all memories connected to the same bus via a processor. CONSTITUTION:An output signal is sent to a write request generating circuit 15 from a processing circuit 11 when a processor 10 performs the parallel and simultaneous writing jobs for all memories 30-1-30-n via firmware.

Title: Communication equipment with pb signal detecting function
Inventor: NASHIMOTO CHUZO
IPC: H04M11/00
Filed: 1991-08-12
Abstract: PURPOSE:To prevent a PB signal from being misdetected, to reduce voice deterioration, and to send a voice guidance with an articulate voice by the communication equipment with the PB signal detecting function even if the voice signal of the voice guidance outputted from a voice output part is propagated around to a PB signal detector. CONSTITUTION:An output amplifier 8 amplifies the voice signal outputted by the voice output part 7 of a voice signal output means 1 and outputs the amplified signal to filter groups 12a-12d (band-elimination filter) which remove only respective low-group frequency components constituting the PB signal. The voice signal after the low-group frequency components are removed by the filter groups is sent out to a line L through a hybrid circuit. Part of the voice signal is propagated around to the PB signal detector 11 of a PB signal detecting means 2, but not misdetected as a PB signal consisting of low-group and high-group frequency components in combination, thereby nearly eliminating voice deterioration.

Title: Blower
Inventor: NIWA KIYOMI
IPC: F24F7/013
Filed: 1981-12-14
Abstract: PURPOSE:To decrease the draft resistance and improve the blowing performance by a method wherein shutters are arranged peripherally at an opening and pivotable around the axes extending radially. CONSTITUTION:When a ventilating fan motor is put into operation by pulling a pull cord (not shown), a ring 10 is simultaneously pivoted to the direction as indicated with the arrow D by means of the pull cord. Consequently, a coupling spring 15 is pulled so as to pivot the shutter 11 to the direction as indicated with the arrow C against a closing spring 14. Accordingly, indoor air is exhausted outdoor. Because the shutter 11 acts as a stationary vane toward the air to be blown-out, the effect to decrease the velocity towards rotational direction of a fan is produced. Consequently, the pressure increases by the amount corresponding to said velocity decrease, resulting in enabling to exhaust against even stronger outside wind than ever. In such a manner as mentioned above, the shutters cause no increase of draft resistance and consequently sure and efficient blowing can be resulted.
