Title: Vinned high speed vessel
Inventor: KIHARA KAZUYUKI
IPC: B63B39/06
Filed: 1984-09-14
Abstract: PURPOSE:To improve the comfortability by stretching fins having negative attack angle from the left/right sides near the bottom at the stern of high speed vessel having initial bow trim thereby lowering the bow section continuously under sailing. CONSTITUTION:In high speed vessel having initial trim where the bottom at the stern 2 will rise against a base line 3 parallel with the water line W toward the rear, a pair of fins 5, 5' having downward negative attack angle are stretched to the left/right near the bottom at the stern where the bottom is lowest against the water line. Under sailing, downward force will function continuously to prevent exposure of the bottom at the stern due to rolling of hull thus to prevent hammering. consequently, the comfortability can be improved without increasing the resistance of full.

Title: Lifting speed shifting device for forklift
Inventor: SAITO YASUSHI
IPC: B66F9/22
Filed: 1996-07-24
Abstract: PROBLEM TO BE SOLVED: To enable switching the lifting speed of a lift cylinder between two of high and low speeds using a single hydraulic pump. SOLUTION: In a device for switching the lifting speed of a forklift, a twist lock switch 4 is used to detect whether or not there is a container C, and a solenoid switching valve 12 is switched accordingly to communicate the rod chamber 2b of a lift cylinder 2 with either a bottom chamber 2a or an oil tank 9. Therefore, when pressure oil from a hydraulic pump 6 is supplied to the bottom chamber 2a of the lift cylinder 2 by operating an oil control valve 7, flow fed into the bottom chamber 2a varies, so that the rising speed of the lift cylinder 2 is switched between two of high and low speeds.

Title: Digital signal receiver
Inventor: OKAZAKI KOUJI
IPC: H04L25/08
Filed: 1983-10-18
Abstract: PURPOSE:To estimate easily a digital signal to be transmitted by estimating each answer signal value at a prescribed time interval from the signal outputted from a reception terminal of a transmission line, and outputting the answer signal value having the maximum absolute value after plural time intervals as the fixed estimated value. CONSTITUTION:When an A/D converter 5 stores the output signal xn of a transmission line to an input register 6 at a time point tn, a processor 7 and an operator 8 extract the estimated signal values y(n-1)(tn-1)-y(n-3)(tn-1) together with answer signal values b0-b2 extracted out of an answer signal value register 11. Thus the signal xn extracted from the register 6 is obtained together with the estimated value yn. Then signal values b0, b1 and b2 are used as threshold values to estimate the estimated signal values successively. Thus the estimated value obtained from the answer signal value having the maximum absolute value is fixed to estimate the fixed signal value.

Title: Hydraulic pressure control valve
Inventor: TAKIMOTO TADAO
IPC: B60T8/26
Filed: 1981-12-03
Abstract: PURPOSE:To enhance the durability of a hydraulic pressure control valve by engaging a piston incorporating therein the hydraulic valve, with a free piston so that the control valve together with the piston is moved upon one system failure for ceasing the actuation. CONSTITUTION:A hydraulic control valve 2 comprising a plunger 4, springs 5 and a poppet valve 6 is incorporated in a piston 15. A free piston 9 is disposed between the springs 5, and is engaged with the piston 15 by means of a check ring 16. Upon normal operation, the piston 15 does not move, but the plunger 14 alone moves toward the center for carrying out pressure reduction. Upon one system failure, the free piston 9 moves to the center due to differential pressure for pulling the piston 15. Thereby the plunger 14 and the piston 15 in the normal system move together so that the control valve 2 remains open, thereby pressure reduction is ceased.

Title: Ground relay
Inventor: NOGUCHI TAKASHI
IPC: H02H3/34
Filed: 1989-07-27
Abstract: PURPOSE:To prevent malfunction due to sudden increase of load current by providing a detecting means which is operated when the magnitude of zero-phase current signal exceeds over a given value, means for detecting a slowly changing component resembling a DC current, means for detecting second higher harmonic component and means for detecting high frequency component upon occurrence of discharge ground fault. CONSTITUTION:When a surge current is generated, the detection signals of 3CTs may include a DC component or may not include the DC component but include a higher harmonic depending on the load. When the DC component is included, a low frequency detector 20 is operated. When the DC component is not included but higher harmonics are included, a second higher harmonic detector 30 is operated to open a normally-closed contact 25b or 35b. At this time, a level detector 13 may also be operated. When the operation time limits of timing circuits 24 and 34 are set short, the contacts 25b or 35b is opened before the contacts 15a of an auxiliary relay are closed, and therefore malfunction is not generated by the surge current.

Filed: 1997-07-22
Abstract: PROBLEM TO BE SOLVED: To lighten load imposed on a cleaning member and to prevent toner from getting through a cleaning part by shielding the toner, which is scooped by a feeding member, using a shielding member. SOLUTION: This device is provided with the shielding member 17 which shields a space from the top panel part of a cleaning container 11 to at least a part lower than the top part(area of dimension H) of a locus formed by the rotation of a feeding blade 14 with respect to the base part of the container 11 between the tip of a cleaning blade 12 and a shaft part 14a being the center of rotation of the blade 14.

Title: Solid-state image pickup device
Inventor: MIKOSHIBA ATSUSHI
IPC: H04N5/3728
Filed: 1988-08-04
Abstract: PURPOSE:To dispense with a memory by allowing a shutter by impressing a pulse whose voltage switching time point is in a horizontal or a vertical blanking period to be synchronized with a vertical driving pulse and applying the pulse to a conductive light shielding film. CONSTITUTION:The title device is provided with a shutter pulse generation circuit 32 to supply pulse voltage which rises from output interrupting voltage in which the accumulated charge quantity of a photodiode becomes below a prescribed value in the prescribed horizontal blanking period preceding a read pulse and in addition, falls below the output interrupting voltage in the vertical blanking period or the later horizontal blanking period while being delayed behind a read pulse to the conductive light shielding film 6. Accordingly, since the maximum accumulated charge quantity of the photodiode changes according to the voltage Vps to be impressed to the conductive light shielding film 6, output voltage becomes as shown in a figure, and when Vps is lowered, the output voltage decreases in proportion to it as well, and disappears perfectly at the vicinity of -7V. Then, Vps at that time is made to be the output interrupting voltage. Thus, shutter time can be made variable without being accompanied with the decrease of a maximum transferred charge quantity and the occurrence of saturation unevenness.

Title: Float valve device whose buoyancy is variably adjustable
Inventor: HIRAIDE KEISUKE
IPC: E03D1/35
Filed: 1995-06-26
Abstract: PURPOSE: To continue washing, even if a handle is released directly after it has been operated, and to supply washing water in a prescibed quantity by forming a cylindrical part in the upper part of a float valve body, by penetrating the cylindrical part to form a passage communicating with the inside of the float valve, by installing a small valve body on the upper surface of the cylindrical part, and also by providing a locking part. CONSTITUTION: At the time of operation of large washing, when a cylindrical part 18 is turned, a small valve body 22 abuts on a locking part 25 for closing the passage of the cylindrical part 18. Therefore, the buoyancy of a float valve body 8 is not changed, and it lowers itself as the water level drops, and when it reaches a prescribed level, it is seated on a valve seat 9 to stop the supply of washing water. Then, when the handle is turned in the position of small washing, the valve body 8 and the cylindrical part 18 are turned in the counterclockwise direction and are raised. Successively, the valve body 8 is locked and stopped by a stopper 15. Then, the small valve body 22 becomes free in the raised position, and is opened by buoyancy. Conseqently, water enters the inside of the valve body 8, and the buoyancy of the valve 8 itself is reduced as much as the inflow of water.  Thereby, the valve body 8 is seated in a higher position as much as the amount, and the small washing of small flow rate is completed.
