Title: Brake system for straight motion
Inventor: HIGUCHI YASUO
IPC: F16D63/00
Filed: 1998-05-14
Abstract: PROBLEM TO BE SOLVED: To prevent the bulging-out of a gasket by setting the contact surfaces of a brake piston and a guide block to be symmetrical left and right, and machining a groove adjacent to a gasket groove. SOLUTION: Gaps are formed in the vicinity of the outer peripheries of both end covers 9 such that a propelling force applied in the axial direction of a brake piston 3 is prevented from reducing the rotational moment of another brake piston 3. If a rotational moment is applied to the brake piston 3, the contact surface of the brake piston 3 is deformed (elastic deformation, plastic deformation or deformation by friction) by a resisting force from a guide block 1. Based on this deformation the rotational center of the inclination of the brake piston 3 is decided. Thus, by setting the contact surfaces of the brake piston 3 and the guide block 1 to be symmetrical left and right and bringing the pressure discharge side of the gasket groove of a gasket 5 to the centers of the contact surfaces, gaps where the gasket 5 does not bulge out are formed.

Title: Ultrasonic probe
Inventor: TAKEDA JUNICHI
IPC: H04R17/00
Filed: 1998-06-04
Abstract: PROBLEM TO BE SOLVED: To increase operability, bearing resolving power in a short distance, and penetration in a long distance of the ultrasonic probe by narrowing a piezoelectric plate in the minor axis direction. SOLUTION: The take-out port of a ground electrode 2, which is formed at the ultrasonic wave radiation side of a piezoelectric plate 1 of this ultrasonic probe, is disposed at an exposed part 7 of the end side in the scanning direction, and the take- out port is connected to the outside using a common ground line 11. As the effective opening width in the minor axis direction is the same as the width of the piezoelectric plate 1 in the monitor axis direction, the width of the ultrasonic probe can be reduced in the minor axis direction, resulting in improved operability.  As, with the same width of a piezoelectric oscillator, the effective opening width in the minor axis direction of ultrasonic wave radiated from the piezoelectric plate 1 becomes larger, even when used for scanning from narrow gaps such as intercostal scanning, a good ultrasonic tomograph is obtained in which reflection noise signal is reduced from the rib. The ground electrode 2 of the piezoelectric oscillator is divided in the minor axis direction and they are selected by a switch, so the effective opening width in the minor axis direction can be varied to form a suitable beam corresponding to an area to be measured, resulting in improving the bearing resolving power in a short distance as well as the penetration in a long distance.

Inventor: IKEDA SABURO
IPC: H04W88/06
Filed: 1994-07-22
Abstract: PURPOSE:To switch a speech path through a radio channel to the one through the subscriber's line of a fixed telephone network and to prevent spectrum exhaustion. CONSTITUTION:A portable telephone 2 which receives radio frequency change from a portable telephone base station 3 is to use the frequency band of the station 3. A position registration part 9 sends out a frequency for a short distance which is different from the frequency band of the station 3 through the station 3 to the telephone 2 as instruction information. The registration part 9 instructs that the frequency for the short distance for a call is to be switched to a portable telephone master unit 4 as well as it instructs the telephone 2 by utilizing a transmission line for sending out ID information. For the speech path through the telephone 2, the station 3, a portable telephone exchange 1 and a subscriber telephone exchange 5 to a subscriber telephone 6 which is a connecting party, the setting of the speech path from the telephone 2 through the master unit 4 and the exchange 5 to the subscriber telephone 6 is completed and changeover is performed without disconnecting the call. Thus, by switching the speech path through the radio channel of a portable telephone network subscriber to the one through the subscriber's line of the fixed telephone network, the spectrum exhaustion of the frequency band of mobile communication is prevented.

Filed: 1984-08-17
Abstract: PURPOSE:To prevent roll-over by directing the delivery flow for mixing toward the layer interface formed in the stored liquid to penetrate it thereby performing limited mixing gradually at the layer interface section. CONSTITUTION:Upon driving of mixing pump 6, the liquid sucked from the bottom of tank is delivered to penetrate the layer interface 10 thus to perform mixing in the vicinity of said interface 10. Consequently, a new layer interface is formed so a mixing nozzle 5 is moved with correspondence to the motion of the interface layer thus to maintain the delivery position slightly below the layer interface at anytime. Said mixing procedure is repeated to produce small scale roll over repeatedly in the vicinity of layer interface thus to proceed mixing gradually over the entire liquid.

Title: Low voltage cmos output buffer
Inventor: JIEIMUZU AARU RANDOBAAGU
IPC: H03K19/096
Filed: 1990-06-28
Abstract: PURPOSE: To obtain an improved output buffer circuit which uses a low voltage source by having an array in which the gate of a P channel pull-up output transistor follows the voltage of an output node. CONSTITUTION: An output node 10 is driven by a push and pull method by a P channel pull-up output transistor 11 and an N channel pull-down output transistor 12. That is, a serial N channel transistor 25 whose gate 27 is connected with a high voltage source +5V and a P channel parallel transistor 23 whose gate is connected with a low voltage source +3.3V allow a gate 13 of the transistor 11 to follow an output voltage which appears at an output node 10 when an output voltage is beyond a value obtained by adding the size of a P channel threshold voltage to +3.3V. At the same time, the transistor 25 holds a source node 26 to be almost +3.3V, and prevents large currents from sinking to the low voltage source. Thus, an improved output buffer circuit with a low cost and a low power can be obtained.

Title: Optical encoder
Inventor: MOMOI MOTOSHI
IPC: G01D5/36
Filed: 1991-07-11
Abstract: PURPOSE:To self-detect the abnormality of an optical system by obtaining the sum-of- squares of the respective output differences of a first subtracting means and a second subtracting means at the light-on time and light-off time to detect the change. CONSTITUTION:The light from a light source 1 passes through a slit 2b to generate sinusoidal wave shape illuminance distribution on a light receiving array and moves on photoelectric converters A1-A4 respectively shifted by 90 deg.. A subtracter 4 computes the output difference of the converters A1, A3 different by 180 deg. in phase, and a subtracter 5 computes the output difference of the converters A2, A4. The output of the subtracters 4, 5 is sampled by an S/H circuit synchronously with each addition of a signal (b) from a sequence controller 11, selected by a multiplexer 8, converted into digital value at an ADC 9 and outputted to a computing element 10. Since offset is included in these outputs, the output difference of the subtracter 4 at the light-on time and light-off time and that of the subtracter 5 are computed to eliminate the influence of the offset, and then the sum-of-squares Y of the difference is obtained to detect the abnormality of an optical system from the fact that the sum-of-squares Y indicates the fixed value when the optical system is normal.

Abstract: PURPOSE:To shorten processing time and improve mass productivity by forming a bearing having a plurality of channels radially curved from the slide surface center and having widths narrowed toward the center and uniform depths formed thereon by plastic working by use of a metal mold having a protruding part having an outer shape to which the channels are transferred and a determined height. CONSTITUTION:The slide surface 1a of a thrust bearing 1 having a spiral dynam ic pressure generating channel 2 formed thereon and the end surface 3a of the shaft 3 are disposed through a fluid film 4 such as oil in such a manner that the both are faced to each other. When the shaft 3 is rotated in the direc tion A, a fluid charged in the channel 2 generates a pressure by pumping effect as the channel 2 has a spiral form and a width reduced toward the rotating direction, and a large fluid pressure is generated in the shaft center part. Hence, a large support load capacity can be obtained. A metal mold 5 for forming the channel has a protruding part 5a having a shape to which the channel is transferred and a determined height, and the protruding part 5a is pressed to the slide surface 1a of the bearing 1 to form the channel 2. Thus, the mass production is facilitated.
