Title: Correction method for time measuring device and time and distanc measuring devices using the method
Inventor: ISHIKAWA YOSHINAO
IPC: G01S17/08
Filed: 1995-02-09
Abstract: PURPOSE: To correct the effect of the fluctuation of a gradient by regularly obtaining the change of lamp voltage within a reference time for finding a gradient value at each phase of the change, and making a correction via the multiplication of the change of lamp voltage within a measured reference time with the inverse number of the gradient value. CONSTITUTION: Correction counters 72 and 73 count clock pulses outputted from a clock generator 71, and outputs signals T01 and T02 . These signals T01 and T02 are respectively set, so as to generate count values N1 and N2 immediately before arrival at the upper limit of lamp voltage immediately after passing the lower limit thereof. Then, a reference time is obtained from a clock period and a count value of (N2 -N1 ). A selector circuit 74 outputs the signals T01 and T02 , upon receipt of the first and second correction start signals, and transmits the signals T01 and T02 to an operation controller 50 via a sample hold circuit 41. The controller 50 finds a gradient value θ1 from the reference time and the change of the lamp voltage.  In a measurement mode, the value of (Vx -Ve1 ) as a difference between the comparison voltage Ve1 of a voltage comparator 20 and voltage Vx based on a measurement object signal is multiplied by 1/ θ1 for correction and a measurement time is thereby obtained.

Title: Liquid-cooled induction motor
Inventor: ITONAGA YASUHIKO
IPC: H02K9/20
Filed: 1993-01-18
Abstract: PURPOSE:To obtain high output while downsizing by employing a double structure in the rotor wherein the outside serves as an evaporation/condensation chamber whereas the inside serves as a cooling liquid chamber. CONSTITUTION:The rotor shaft 7 of a rotor 1 is provided with a cooling liquid chamber 4 extending in the longitudinal direction and an annular vacuum enclosed evaporation/condensation chamber 2 is disposed around the cooling liquid chamber 4 with a small quantity of distilled water being contained therein. The liquid in the evaporation/condensation chamber 2 is collected on the inner wall face at the outside through the centrifugal force and evaporated by the heat of the rotor 1 to shift to the inside. The liquid is then cooled by the cooling liquid 3 in the cooling liquid chamber 4 and condensed to discharge latent heat. The condensed liquid is shifted to the outside by the centrifugal force. In other words, heat is exchanged constantly under a state where the liquid in the evaporation/condensation chamber 2 is shifted to the outside. This constitution produces high output while downsizing.

Title: Boundlessly sliding ball spline bearing
Inventor: TERAMACHI HIROSHI
IPC: F16C29/00
Filed: 1980-02-25
Abstract: PURPOSE: To improve the working efficiency by forming one by one or simultaneously U-shaped grooves for load balls and grooves for no-load balls on the inner surface of an outer cylinder in the radial direction by the broaching techniques or slotting techniques.  
     CONSTITUTION: The U-shaped grooves 11, 12 and 13 for load balls are formed in inner holes of the outer cylinder 10 by means of the broaching techniques. The grooves 21W26 foe no-load balls are formed in the same way. A contact angle θ on an extension of a line interconnecting the load ball 14 and no-load ball 27 is rendered as near as possible to the torque direction O 1 -O 2 -Y, thereby minimizing the outer diameter of the outer cylinder 10. By this, the no-load ball grooves 21W26 and load ball grooves 11W13 can be formed by the broaching techniques at the same time, which results in a reduction of working time. As the distance between the load ball 14 and no-load ball 27 in the radial direction is so short that the influence of the centrifugal force at a high speed rotation can be minimized.

Title: Core of curtain
Inventor: AOYAMA YUKIO
IPC: D04B21/14
Filed: 1996-01-13
Abstract: PROBLEM TO BE SOLVED: To make a core flexible bendable, and increase the vertical compressing force by making the core formed of braided texture formed by braiding a vertically extending warp and a horizontally extending weft, and setting the rigidity of the weft larger than the warp. SOLUTION: A warp 5 is formed of a bundle of extremely fine filaments, which is soft and has a small rigidity. The warp 5 is vertically extended while forming a loop, and wefts 6a, 6b... are entangled with the warps 5 to constitute a braided texture. Namely, the weft 6a is entangled with all, of warps 5, 5... arranged at equal intervals, and wefts 6b, 6c... are entangled with three warps 5, 5.... As the weft, high tension yarn as a fine leveling string is used, and the strength and rigidity are set high, compared with the warp. Thus, although the core is hardly deformed to an external force from the lateral direction of the core, it can be easily bent in the longitudinal direction because of the small rigidity of the warp. Further, the resulting curtain is never sagged between hanging fittings.

Title: Method for controlling compression ignition type internal combustion engine
Inventor: AWASAKA MORIYOSHI
IPC: F02P5/15
Filed: 1999-01-29
Abstract: PROBLEM TO BE SOLVED: To ensure the stability of combustion and satisfactory startability in a low load operation in an internal combustion engine switchable between compression ignition combustion and spark ignition combustion according to an operating state by performing the switching from the spark ignition combustion to the compression ignition combustion while gradually delaying the ignition timing. SOLUTION: An ECU 2 switches the operating state to spark ignition combustion (SI combustion) by spark ignition in a low load or the starting of an engine 3 and to compression ignition combustion (CI combustion) by compression ignition in operations other than the above to control the operation. In this case, when the SI combustion is switched to the CI combustion, the ignition timing is gradually retarded in delay angle from the ignition timing in the SI combustion to be switched to the CI combustion. Accordingly, the compression ignition is made to finally precede the spark ignition to prevent a large slippage in ignition timing, and the output of torque is gradually reduced to ensure and smoothen the transfer to CI combustion, so that satisfactory operability can be provided.

Abstract: PURPOSE:To prevent water in a toilet from impinging against a urine absorber by providing a back surface receiving plate having a protruding part covering the back surface of the urine absorber and protruding toward the side part of the urine absorber to the back surface of the urine absorber. CONSTITUTION:A sheath-shaped cap 18 is detached from a fitting part 19a and fitted to the fitting part of a connection holder 17 to elongate the whole. Next, a holder 1 is bent with respect to the holder 17 and a urine line is brought into contact with an exposed urine absorber 14 in such a state that the cap 18 is grasped. In this case, a part of the urine line impinges against the protruding part 35b of a back surface receiving plate 35 and transfers to the protruding part of the absorber 14 from the protruding part 35b to be absorbed into the absorber 14. Since the receiving plate 35 covers the back surface of the leading end part of the absorber 14, water of a toilet, is prevented from splashing on the absorber. Next, the absorption of urine is confirmed by the color change of the urine wetting checker part 25 of the absorber 14.

The optic signal OS is received by an optic fiber 5 in the vicinity of the neutron absorbed position P as an expected quantity of light and transmitted to two photoelectric converters 8 from a light introduced position via the optic fiber 5.  Detection signals S1, S2 of the photoelectric converters 8 are output to a signal processor 9, difference in quantities of light across the optic fiber 5 is calculated, the light introduced position of the optic fiber 5 is specified from the difference, the neutron absorbed position P of the wire 4 is estimated, and the estimated results are monitored as data regarding an spatial output distribution of neutrons.
