Title: Pressure reducing valve
Inventor: HASEGAWA YOSHIHIKO
IPC: G05D16/20
Filed: 1986-08-12
Abstract: PURPOSE:To obtain a pressure reducing valve containing a flow meter by detecting the pressure at a primary and a secondary sides of a main valve opening after detecting the opening amount of a main valve body and giving the arithmetic processing to those detection signals for measurement of a flow rate. CONSTITUTION:A primary and a secondary pressure signals are sent to a computing element part 3 from pressure sensors 66 and 68 respectively. The displacement of a main valve 18 caused in the axial direction is sent to a shaft 62 of a detector 58 via a main valve shaft 46. Then the shaft 62 is expanded and contracted by a spring 64 and the displacement signals are sequentially sent to the part 3. The part 3 stores previously the relationship between the displacement value of the valve 18 and the Cv value by an experiment and calculates the data with which the Cv value is read against the opening amount of the valve 18, the data with which the pass area of the main valve opening is calculated from the deflection of the valve 18, and the data on the difference of pressure levels between two sensors 66 and 68 respectively based on said relationship to obtain the volume flow rate. In such a way, the maximum productivity is secured per unit time with small steam consumption. Furthermore the steam productivity control that attains production of products of high quality is secured by means of a flow meter incorporating a pressure reducing valve.

Title: Recording material storing device
Inventor: TAMURA SATOSHI
IPC: B65H3/46
Filed: 1996-07-19
Abstract: PROBLEM TO BE SOLVED: To prevent the image unevenness on a recording material by sealing a device so as to keep the moisture content in the air within the device, and imparting the moisture to the air within the device. SOLUTION: A frame body 101 is roughly divided into a recording member storing part S and a water storage part W by a partitioning plate 102. A water holding material such as sponge is filled in the water storage part W for water holding. The moisture of the water storage part W tries to form an equilibrated state by releasing the moisture into the air within a device so that the moisture content in the air within the device is a saturated moisture content corresponding to the temperature of the storage environment. Since the moisture in a recording material also tries to keep the equilibrated state with the moisture content in the air within the device to absorb and release the moisture, the device is stabilized in a constant moisture content.  Thus, the image unevenness can be prevented from being caused by that paper or a water absorptive film is left in the dry air in storage to increase the electric resistance.

Title: Film carrier tape
Inventor: TAKEGAWA KOICHI
IPC: H01L23/50
Filed: 1986-08-15
Abstract: PURPOSE:To make a film carrier tape to correspond to a semiconductor chip with a large number of leads by zigzag disposing pads for electric selection on the film carrier tape on the circumference of a circle or a concentric circumference. CONSTITUTION:Pads 5 for electric selection are arranged zigzag on circles C1, C2 centering around the central point of a device hole 3. When electric selection is executed by probing needles 13 regarding a film carrier tape constituted in this manner, the probing needles can be disposed most efficiently because the probing needles 13 for a probing card 10 are arranged along the outer circumference of a circular opening section 12. Consequently, the number of the probing needles disposed can be maximized. Accordingly, the pads 5 for electric selection capable of being arranged onto the film carrier tape are limited only by the size and pitches of the pads for electric selection required for electric selection in the probing needles and the pitches of the probing needles capable of being disposed to the probing card, thus allowing the arrangement of the probing needles in several times as many as conventional devices.

Abstract: PURPOSE:To improve the performance of the thin film transistor(TFT) of a peripheral driving circuit part and to make an LCD large in size and have high definition by constituting a member in the active area of a part of semiconductor element of a monocrystal semiconductor. CONSTITUTION:A monocrystal silicon material 8 is arranged around a transparent glass substrate 1 and the TFT active area 7 in the driving circuit part TFT 4 is formed of the monocrystal silicon. Since the TFT 3 and a transparent electrode 6 in a picture element part are formed on the transparent glass substrate 1, the picture element part transmits light and is applied in a light transmission type liquid crystal display LCD. Then, the TFT active area 7 of the driving circuit part TFT 4 is excellent in crystallization because it is formed of the monocrystal Si. Thus, the characteristics of moving degree, threshold voltage and off-state current of the TFT are improved and the LCD is made to have high definition and made large in size.

Filed: 1997-07-17
Abstract: PROBLEM TO BE SOLVED: To provide a video communication system in which a partial video image sent from different video servers is integrated as one video content at a receiver side and the image is continuously displayed. SOLUTION: Video data at the head of a partial video image to be received next at a video reception terminal are transferred from a video server 103 for storing the above data to a video server 102 for storing one preceding partial video image, so as to allow the video server 102 to send a head of a succeeding partial video image immediately after the transmission of the partial video image without interruption. Thus, the effect of fluctuation in a delay time is reduced and a buffer underflow at the reception side is suppressed. Furthermore, the video reception terminal 105 is provided with two buffer sections 124, 126, and the video data are shared depending on senders to allow the two video servers 102, 103 to easily detect the part received in duplicate and either of them is deleted. Thus, mixture of the video data at the border of the partial video image is avoided.

Abstract: PROBLEM TO BE SOLVED: To reduce the size of a charging device for an electric vehicle, by using when charging its battery both a bridge circuit comprising the semiconductor driving switching elements of a DC motor for its power steering and one arm comprising the semiconductor driving switching elements of an inverter for its traveling. SOLUTION: In this circuit, (+) and (-) power supply lines 2, 3 of a battery 1 are connected by an arm 5, comprising two switching elements 4 connected in series with each other, and similarly, switching elements Q3, Q4 constitute an arm. When the voltages of a three-phase AC power supply 17 are applied to terminals R-T, a DC current is made to flow through a coil 22 of a contactor 7 and contacts 8-10 are switched to their battery charging sides respectively. When charging the battery 1, switching elements Q1-Q6 are turned on and off, but no current is applied to a DC motor 14 and AC motor 16, since the contacts 8, 9 are not switched to their DC motor sides and switching elements Q7-Q10 are brought into off-states respectively.  Also, current sensors 11, 12 and control circuit for moving an electric vehicle can be shared, when moving the electric vehicle and when charging its battery 1.
