Patent JP-H02172339-A (JP)
Title: Synchronization method
Inventor: TOMABECHI AKITAKA
IPC: H04L7/00
Filed: 1988-12-26
Abstract: PURPOSE:To reduce overhead required for establishing the bit synchronization of communication by applying subordinate synchronization to a terminal station with respect to a base station. CONSTITUTION:In the case of sending a signal from a terminal station 50, the subordinate synchronization system to an outgoing line is adopted, while a base station 1 controls the phase of received recovery clock to a value calculated in advance from signal speed and a distance up to a remotest station 50 and reaches the standby state. That is, when the signal speed is sufficiently smaller than the propagation distance, the final phase of bit synchronization at the base station 1 is nearly equal independently of the transmission by the terminal station 50 anywhere by applying subordinate synchronization of the terminal station 50 with respect to the base station 1 and the base station 1 has only to await the communication at a predetermined phase for each communication. Thus, a phase tracing range is decreased and the overhead required for establishing bit synchronization at the base station side is reduced.

Title: Hammer for measuring sensitivity to impact
Inventor: MIZUSHIMA YOJIRO
IPC: G01P15/00
Filed: 1993-12-24
Abstract: PURPOSE:To offer an easy-to-use compact portable hammer for impact sensitivity test of a gunpowder, etc., by providing a hammer head with an accelerometer or means of recording an impact. CONSTITUTION:An accelerometer 3 is mounted on the head 2 of a hammer fixed to a tip of a handle 1. The accelerometer 3 may be mounted on the head 2 by adhesion or other means, or embedded in a recess cut in the head 2. The accelerometer 3 may be mounted on any part except for a hammering part 4. It could be damaged during an impact test if mounted on the hammering part 4. The accelerometer 3 may be of any type such as piezoelectric element or strain gauge, if only it can measure acceleration. A piezoelectric type accelerometer is compact and resistant to impact. The head may be provided with an accelerometer mounting part for easy mounting and dismounting, so that it can hold a most suitable accelerometer, because a degree of impact varies depending on an object to be hammered or type of a test.

Filed: 1990-11-28
Abstract: PURPOSE:To enable measurement of a change in the frequency characteristic of a video amplifier in a state of a clamp function being operated, by providing a DC voltage source outputting a prescribed DC voltage and an output switching means of selecting and outputting the DC voltage. CONSTITUTION:An output switching means 38 of selecting and outputting a DC voltage of a DC voltage source instead of an output signal from a signal generating element 21 during a period when a first sync pulse is received, is provided. Every time when sweeping of a signal in a desired frequency range is ended, the DC voltage from the voltage source 36 is outputted instead of this signal, and a pulse is outputted from a second sync pulse output element 33 during a period when this DC voltage is outputted. By inputting an output signal from the means 38 to a video amplifier 1 of a clamp type and also by inputting the second sync pulse as a clamp signal, therefore, the frequency characteristic of the amplifier 1 can be measured.

Title: Dc brushless motor
Inventor: KOSHIN HIROAKI
IPC: H02K29/08
Filed: 1988-12-23
Abstract: PURPOSE:To lower noise level by detecting the load of a DC brushless motor comprising a permanent magnet rotor and a stator having a current switching Hall element, and controlling switching of current according to variation of load. CONSTITUTION:Hall elements (HU-HW, in case of three-phase) are connected in series between a power source V and the earth. The Hall elements H correspond to detecting magnets magnetized sinusoidally, and the outputs therefrom are fed to differential amplifiers I1-I3 comprising operational amplifiers A1-A3 and resistors R3-R4. Then their outputs are fed to hysteresis comparators(HC) 21-23 comprising operational amplifiers C1-C3 and resistors R15-R32. Noise level under no-load is compared with a reference voltage corresponding to rotation, and the output from the comparator is employed for turning transistors QU-QW connected with stator windings LU-LW ON/OFF. Then output from the differential amplifier I3 is subjected to F/V conversion 15 thus controlling the HC 21-23. By such arrangement, coil current is switched such that the noise is minimized regardless of variation of load.

Title: Method and device for coupling bit-line sense amplifier of semiconductor element with data bus line
Inventor: JO TEIGEN
IPC: G11C11/409
Filed: 1997-11-13
Abstract: PROBLEM TO BE SOLVED: To secure the design margin of the cell core area and to reduce problems in metal processes by dividing 2M bit-line sense amplifiers selected by the output of the column decoder into 2B groups and selectively connecting 2M<-> B bit-line sense amplifiers with data bus lines. SOLUTION: When the NMOS TR, etc., of the first transmission section 11 are simultaneously turned on by a high signal generated by the column decoder, there are some cases where mutually different kinds of amplified data are simultaneously transmitted to the first data but line or the sensor data bus line. In order to prevent this, many MOS TRs, etc., are required. If the first bit line sense amplifier group selection signal is high and the second bit line sense amplifier group selection signal is low under the condition that many MOS TRs, etc., of the first transmission section 11 are simultaneously turned on, the TRs, etc., connected to the selection lines are turned off and no data is transmitted.

Title: Tone replenishment tank
Inventor: ANDOU YUKIMORO
IPC: G03G15/08
Filed: 1991-12-11
Abstract: PURPOSE:To prevent toner replenished from an opening from depositing on a toner agitator-by making the toner agitator heavy on one side in the width direction than on the opposite side against a shaft, and holding it longitudinally when the toner is replenished. CONSTITUTION:The opening 11 for toner replenishment is provided above the toner agitator 20 which is rotatably included. This toner agitator 20 is made larger in weight on one width-directional side 22 than on the opposite side 23 about the shaft 21, and held with the heavy side 22 down at the time of toner replenishment wherein the load of toner is eliminated. Namely, when the toner replenishment tank is emptied and no load is placed on the toner agitator 20, the toner agitator 20 rotates naturally so that its one heavy side 22 falls, and stops in the longitudinal state. Therefore, the toner agitator 20 is not horizontal even when the toner is replenished from the opening 11, so the toner is deposited on the horizontal part of a connecting lever 24, so that the toner is not stacked in the replenishment tank.

Title: Apparatus for heat sealing film bag in automatic packing machine
Inventor: OUGIYAMA HIROYUKI
IPC: B65B51/10
Filed: 1987-12-24
Abstract: PURPOSE:To permit an immediate corrective action to be taken as required in order to prevent the occurrence of defective products and thus improve productivity, by detecting the entrapment of foreign substances being the cause of an improper heat sealing by clearance sensing means. CONSTITUTION:This apparatus is placed in variable operating conditions in accordance with variable clearances between hot plates 1 and 1'. Sensors 20 (e.g., switch) for electrically detecting a decrease in the predetermined size of clearance S between a bracket 11 and a hot plate mounting member 13 are positionwise in an adjustable manner fixed into a supporting hole 21 formed at each end of the bracket 11. In the case of an entrapped content overflowing from the opening portion of a film bag A between the hot plates 1 and 1', the minimum clearance therebetween is enlarged and, therefore, the hot plate mounting member 13 is forced toward the bracket 11 by the thickness of the foreign substance. During this time, if the position of the hot plate mounting member 13 is within the detectable range of either of the sensors 20, it generates a detection signal of the entrapment of foreign substances.
