Title: Axial piston pump/motor
Inventor: MIZUTANI KOUZOU
IPC: F03C1/253
Filed: 1984-04-24
Abstract: PURPOSE:To aim at prolonging the life of a pump/motor, by leading pressure fluid into a small closed gap among the outer race of a slidable bearing, a casing and a front casing to press the outer race so that the thurst force of a shaft may be distributed to both bearings. CONSTITUTION:Upon discharge of pressure fluid the thrust force transmitted from pistons 6 to a shaft 2, is applied to a bearing 3 secured to a casing 1 and a slidable bearing 4 disposed in the casing 1. However, high pressure fluid fed from a cylinder block 5 through a circuit 15 is led into a small closed gap 14 among the outer race 4a, the casing 1 and a front casing 12 so that outer race 4a is pressed, and thereforce, the thrust force of the shaft 2 is distributed to both bearings 3, 4 and born thereby. With this arrangement, the life of both bearings 3, 4 may be made longer than that of the conventional arrangement in which the thrust force is received by the stationary bearings 3 alone. As a result the life of the pump/motor may be prolonged.

Title: Oxygen detector
Inventor: ERITSUKU RIANNYUIN KAA
IPC: G01N27/407
Filed: 1990-03-30
Abstract: PURPOSE: To manufacture a highly reliable oxygen sensor excellent in durability easily and inexpensively by providing a flat planar solid electrolyte having a measuring electrode and a reference electrode and specifying the profile thereof. CONSTITUTION: The oxygen detector comprises a substantially flat solid electrolyte 12 having a measuring electrode 14 and a reference electrode 16. In the operation, the electrode 14 touches an external gas to be measured but the electrode 16 is substantially sealed hermetically from the external gas. The solid electrolyte 12 has end parts 34, 37 and two side parts each of which comprises two parts meeting at a top part 32 interposed between the end parts 34, 37. Consequently, the width of the electrolyte 12 is maximized between respective top parts 32 and tapered in the opposite directions from each top part 32 toward the end parts 34, 37. This structure enhances durability of the ceramic solid electrolyte to prolong the service of oxygen detector.  Furthermore, a detection element 10 can be manufactured easily and inexpensively because it can be fixed in an oxygen sensor assembly and positioned in place by itself.

Title: Electronic watch with lighting device
Inventor: TSUJI TOMOHARU
IPC: G04B19/30
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To achieve an arbitrary, local light emission without being restricted by a light emission time and to recognize time even in the darkness by providing an ultraviolet ray generation means and a photosensitive part that is sensitized by ultraviolet rays and emits light at a display part and a switch for turning on lighting outside. SOLUTION: A light emission means 103 receives ultraviolet rays from an ultraviolet ray generation means 12 and hence is excited and emits light. When the light emission means 103 accumulates light sufficiently in the darkness, it continues a self light-emission for a certain period of time and one can recognize time. However, as the amount of accumulated light is discharged, a light emission luminance decreases gradually, and time cannot be recognized. Therefore, even if time cannot be recognized, the ultraviolet ray emission means 12 is turned on by a switch means 101 arbitrarily and ultraviolet rays are applied to the emission means 103, thus exciting the emission means 103 again for re-emission.  Also, an optical film for reflecting ultraviolet rays is formed on the inner surface of a windscreen to prevent ultraviolet rays from escaping toward the outside, thus further increasing the emission luminance of the emission means 103 for improved efficiency.

Title: Piezoelectric actuator
Inventor: OSHIMA KIYOSHI
IPC: H02N2/00
Filed: 1998-03-27
Abstract: PROBLEM TO BE SOLVED: To improve reliability in a state of high temperature while a metal case of simple structure is used, by mutually bonding the tip part of a piezoelectric element and the inner surface of the metal case. SOLUTION: When a piezoelectric element 2 is expanded and contracted by applying a voltage to a pair of external electrodes of a multilayered piezoelectric element main body via lead wires 4, since the protruding part 3 of the tip part of the piezoelectric element 2 is bonded to the inner surface of the tip part of a metal case 5, a flexible part 6 of the metal case 5 is deflected in accordance with expansion and contraction of the piezoelectric element 2, and the tip part of the metal case 5 accurately follows expansion and contraction of the piezoelectric element 2. At this time, since the flexible part 6 of the metal case 5 has flexibility so as to be deflected by a small force, displacement of the piezoelectric element 2 is not reduced by a reactive force of the metal case 5.  In addition, when the metal case 5 is thermally expanded in a state of high temperature, the piezoelectric element 2 in the metal case 5 can be prevented from suffering a tensile force by deflection of the flexible part 6.

Filed: 1985-04-17
Abstract: PURPOSE:To make it possible to execute resending of continuous error surely by using a circuit doubly stopping echo suppressor function in the period of actual data communication even when signal interruption occurred during procedure. CONSTITUTION:When a call signal CI is received from a transmitting side, a receiving side outputs a called station discrimination signal CED. Then, the transmitting side is informed of whether there is function of resending continuous error by an initial discrimination signal NSF that shows non-standard function. In the case where an operator in the transmitting side selected error resending function, and the receiving side has the function, transmission is made making 50th bit of FIF of a non-standard equipment set signal NSS 1. On receiving a receiving preparation confirmation signal CFR, the transmitting side sends out a tonal signal of 2,100Hz per second as a tone for stopping echo suppressor function, EST, and sends out a training signal and a message signal by signal interruption of less than 100ms. Accordingly, the circuit can be used full doubly during sending of a message, and resending of continuous error is executed.

Abstract: PURPOSE: A rotary cutter is set above the an endless belt and a means is provided for resisting the thrust of the blade into a bamboo shoot, whereby the bamboo shout is peeled without breakage at their tip.  
     CONSTITUTION: A bamboo shoot is placed on the endless belt 6 and sent to beneath the rotary cutter 11 which revolves in the reverse direction to the running belt 6. The blades 14 on the rotary cutter 11 are at an angle to the belt- running direction and the height of the inner end of the blade is made larger than the outer end. The bamboo shoot is pushed in between the belt 6 and the blades 14 where incisions are made and skins are loosened. At this stage, the shout is pushed foward by the rotation of the blades but blocked to go with the back edge 9 of the guide plate 8. Thus, the loosened skins are peeled off from the tip top by the blades, then, the naked shout gets over the back end 9 and goes forward.
