Inventor: OOKUBO HIROHISA
IPC: E02D5/08
Filed: 1999-06-16
Abstract: PROBLEM TO BE SOLVED: To secure a required shear strength in a joint at a construction site by fitting a circular steel pipe constituting the joint member setting the axis in parallel to an external face of the steel sheet pipe pile body and forming a slit axially stretching in the circular steel pipe and forming a plurality of through holes in specified positions of the circular steel pipe. SOLUTION: A circular steel pipe 2 having a smaller diameter than a steel pipe sheet pile body 1 is welded to the external face of the steel pipe sheet pile body 1. A fitting slit 2a is formed along the axial direction of the pipe in the circular steel pipe 2. A plurality of through holes 7 are formed on the whole face, when the inside face of the longer side 2b of the arc length in the arcs 2b, 2c forming between slits 2a of the fitting part 5 to the sheet pile pipe body 1 of the circular steel pipe 2 turns to the steel pipe sheet pile body side 1, that is, in the fitting part through slits 2a in the other circular steel pipe 2. In this way, even if the fitting space B of mutual steel pipes of P-Ptype joint member gets extremely narrow, they can be securely cleaned and filled with mortar.

Title: Braking device
Inventor: NAKAJIMA KOJI
IPC: E06B11/02
Filed: 1995-06-13
Abstract: PURPOSE: To make adjustments between a brake body and a braking operation means and also each individual play adjustment of a braking device performable by attaching an adjusting plate tight to a camshaft integrally installed in a cam, while installing a braking lever to be connected to the braking operation means, in this camshaft free of rotation. CONSTITUTION: A bolt 20 is loosened to some extent, while a braking lever 5 and an adjusting plate 18 are made into a state of being freely rotable with a camshaft 16 as the center, and then this adjusting plate 18 is clamped tight, rotating the braking lever 18. A cam and the adjusting plate 18 are unified as one body, so if the adjusting plate 18 is not moved, a position of the cam remains unchanged, therefore positional adjustments in the braking lever 5 become performable. After the braking lever 5 is made into a desired position, the bolt 20 is clamped, and then the braking lever 5 and the bolt 20 are secured tight. With the positional adjustment of the braking lever 5, the adjustment of an interrelationship between the brake body and the braking operation means can be done easily. Moreover, the adjustment of play in the brake body itself is easily performable, while even in the case where there in a secular change in lining wear or the like, it is adjustable.

Title: Method and device for expanding dynamic range of frequency mixer
Inventor: MYER ROBERT EVAN
IPC: H03F1/32
Filed: 1999-06-17
Abstract: PROBLEM TO BE SOLVED: To provide a mixer of a dynamic range that becomes wider. SOLUTION: A frequency mixing system uses a feedforward device to reduce the distortion of a signal which occurs due to the amplitude adjustment of an input signal and generates a needed frequency conversion signal which includes the cross modulation distortion of a level that is lower and/or allowable. For instance, the distortion of a signal from a 1st path can be introduced onto a 2nd path 22 and next, a frequency converted by using a 2nd mixer 38 on the path 22 is returned to the 1st path to supply a necessary frequency conversion signal including the cross modulation distortion of a level that is allowable and/or lower and to connect with the distortion of the signal on the 1st path.  The frequency mixing system supplies an expanded dynamic range by increasing the difference between the amplitude of the necessary frequency conversion signal and the amplitude of the cross modulation distortion.

IPC: H03M5/12
Filed: 1980-12-05
Abstract: PURPOSE:To reduce the bit error rate, by using a counter to minimize the phase difference between the split phase code (SP code) and clocks in case of conversion of the SP code to a non-return-to-zero (NRZ) code. CONSTITUTION:Data A which is inputted from a terminal 1 and is encoded to the SP code is shaped by a comparator 2 and is branched to two, and one is connected to an exclusive OR circuit 7 for conversion to the NRZ code, and the other is connected to a clock extracting part 3. Clocks C extracted by the extracting part 3 are delayed in a counter 11 of the first stage by a count time rmus and are delayed in a counter 12 of the second stage by a count time 10mus to become a signal F, and the phase of the output F of a PLL circuit 10 is matched to the phase of an output B of the comparator 2. Therefore, whiskers (w) of the NRZ code are eliminated almost in an output G of the circuit 7, and the output G is integrated for every bit by an NRZ code regenerating circuit 9, and whiskers (w) are eliminated, and thus, the bit error after NRZ code regeneration is reduced.

Abstract: PURPOSE:To improve the effect of flocculation and to improve filtering and dehydrating properties by irradiating ultrasonic waves to waterworks sludge contg. aluminum hydroxide at 25-100kg. DS/DW/hour speed then adding polymer flocculating agents thereto and filtering and dehydrating the sludge.

Title: Controller for hybrid vehicle
Inventor: OYAMA KAZUO
IPC: B60L50/15
Filed: 1996-06-12
Abstract: PROBLEM TO BE SOLVED: To improve the efficiency of regeneration by means of a motor, by appropriately controlling the regeneration and drive by the motor when a vehicle is decelerated by detecting abrupt deceleration of the vehicle, based on the driven state of the vehicle, and controlling the output of the motor to a prescribed positive value upon detecting the abrupt deceleration. SOLUTION: A driving shaft 2 of an internal combustion engine 1 drives a driving wheel 6 through a transmission 4 and a clutch 5, and a motor 3 which is provided so that the motor 3 can directly drive the shaft 2 has a regenerative function which converts the kinetic energy resulting from the rotation of the shaft 2 into electric energy and outputs the electric energy. When it is detected that a brake is operated to abruptly decelerate a vehicle, the operation of the motor 3 which has a fast speed of response is first switched to assisting drive of the vehicle from regeneration, so as to prevent the occurrence of an engine stall.  At the time of shifting the operation mode, the initial torque value of the motor 3 is set at the regenerative torque immediately before the switching of the operation mode plus the friction torque of the engine 1 and, thereafter, the efficiency of the regeneration is improved by controlling the torque of the motor 3 so that the motor 3 can smoothly shift to an idling state and reducing the number of revolutions of the engine 1, when the vehicle is decelerated.

IPC: G03B27/50
Filed: 1991-06-18
Abstract: PURPOSE:To provide an image forming device having an optical system lessening the frequency of cleaning. CONSTITUTION:A mirror 23 to reflect reflected light from an original 29 to photosensitive material 5 is set to be capable of shifting to three positions, a photometry position A setting a reflecting surface almost downward, a exposure position B and a comforming position C reflecting the light to an image formation plate 30 for visual confirmation provided on the upper part of the main body.
