Abstract: PURPOSE:To increase driving efficiency, in a moving wheel used for running a vehicle and the like, by feeding and discharging pressure fluid in two working chambers, between a lens shaped sectional rotor and rotor housing, through a fixed eccentric shaft and an internal passage of the rotor. CONSTITUTION:Pressurized fluid flows in a passage 39 of a rotor journal 33 from a passage 38 of an eccentric shaft 37 to reach a groove 34, and passages 31 in a rotor 14 are connected by rotary motion, then the fluid flows into a working chamber 16, while a rotor housing is rotated in such a manner as to expand its volume, thus fluid in a working chamber 17 is discharged. When the rotor motion reaches the next dead center, a relation between the fluid passages 31, 31' and grooves 34, 34' of the rotor journal is inverted, and pressure fluid, flowing into the working chamber 17, continues rotary motion. In this way, the necessity for a mechanical power transmission mechanism can be eliminated to decrease power loss and weight. Further a rotary speed can be easily controlled by adjustment of a feed amount, and action of a brake can be also easily performed.

Title: Plate type solid electrolyte fuel cell using mesh with different wire diameters
Inventor: HISHINUMA YUICHI
IPC: H01M8/12
Filed: 1994-07-29
Abstract: PURPOSE:To improve the current collecting efficiency and the absorption rate of internal stress of a fuel cell, so as to improve the performance, by making the wire diameter of a heat-resisting metallic mesh, the finer at the layer the closer to a fuel electrode.

The wire diameter of the mesh 7 is made finer at the layer near the fuel electrode of the unit cell, and composed of a rough meshwork with the larger wire diameter at the other layers. When the wire diameter of the mesh is fine, the meshwork is made smaller, and the mesh contacts closely to the electrode so as to increase the conductivity and improve the current collecting efficiency. And since the wire diameter is large at the mesh near a separator, the meshwork is made larger so as to facilitate the ecconomy.

Abstract: PURPOSE:To simplify the service of charge-payment by adding charge-data during the time when a calling subscriber is using a specified master-charged system to the charge-data in the subscribers area of the specified master's telephone number. CONSTITUTION:When the subscriber, for instance, is a general one and hence the master-charge is not applied, a subscriber category is '0', and a master- charge display is also '0'. In case plural subscribers form a representative group, when a representative registration is executed by issuing a command, the value of the subscriber category turns to be '2' showing the representative, however, if the master-charging is not being used but is the separate charging, the master-charge display remains '0'. If the master-charge is registered by issuing a command so that the master-charge is executed against this group, the said display turns to be '1'. In a file memory, various kinds of data, telephone-number data, an auxiliary block, a representative-group list, and a subscriber's meter are written in addition to the subscriber's data. As a result, the service pertinent to the payment of the charge is simplified.

Title: Response-to-refraction type ultrasonic non-linear type parameter ct
Inventor: NAKAGAWA YOSHIKATSU
IPC: A61B8/00
Filed: 1988-07-18
Abstract: PURPOSE:To reduce deterioration of the picture quality of a reconfiguration tomogram due to refraction by a method wherein a hydrophone array having a wide bore is used as an echo sounder receiver in order to prevent incurring of a wave receiving loss due to refraction of ultrasonic waves by which deterioration of the picture quality of the reconfiguration tomogram is caused mainly. CONSTITUTION:When differential frequency waves are used and when second higher harmonic waves are used, an echo sounder receiver is situated in both cases so that the center thereof is located on the sound axis of echo sounder beam. An echo sounder transmitter 2 and the echo sounder receiver 4 are scanned simultaneously in the same direction (a direction A or B), and by using a conventional algorithm, a non-linear parameter tomogram is reconfigured. In this case, when the echo sounder receiver having a small bore is used, it fails to receive ultrasonic beam which is refracted within a sample and changes its coarse. However, when an array is used, an echo sounder can be received throughout a wide range, and the receiver is prevented from failing in receipt of ultrasonic beam. This constitution enables measurement of a non-linear parameter tomogram which reduces deterioration of a picture quality due to refraction.

Filed: 1983-09-28
Abstract: PURPOSE:To reduce power consumption and to attain extremely high speed operation by inserting an E-type transistor (TR) constituting a transfer gate between the gate of an intrinsic TR constituting the 1st switching circuit and the output terminal of a pre-stage word line. CONSTITUTION:If the output terminal potential VW1 of the pre-stage word line is boosted up to some level at the time of selection, a TRQ'I is turned on. When the 1st control signal phiW1 is boosted up to VDD, the gate voltage of the TRQ'I is boosted moreover and conductance is increased moreover. When the TRQ'I is turned on and the source potential is increased, the gate potential of the Q'I is more boosted by bootstrap effect, the source potential is increased up to the VDD without turning off the TRQ'1 to boost the post-stage word line W2 so as to be selected state. Thus, the selecting operation is moothly performed under low power consumption, and at the non-selected time, the potential of the word line is quickly dropped by the TRs QE3, Q'I.
