Title: Clock switching circuit
Inventor: ASANO EISUKE
IPC: H03L7/00
Filed: 1991-04-16
Abstract: PURPOSE:To considerably reduce the omission of data or the probability of generating overlapping by selecting a delayed clock or the other not-delayed clock, dividing the frequency into 1/N and processing a digital signal with this clock as a reference. CONSTITUTION:Clock generating circuits 1 and 2 constitutes a redundant system, one output is inputted to a delay circuit 7 and the other output is inputted to a clock switching circuit 3. The respective clocks are inputted to a phase difference detection circuit 6 as well, phase difference is detected and according to this phase difference, the circuit 7 delays and outputs the clock from the circuit 1 in the range of O-2pi radian. By this delay, the phase difference between the clocks from the circuits 1 and 2 can be suppressed at a minimum. These clocks are selectively switched and outputted by the clock switching circuit 3. The frequency of the switched and outputted clock is divided into 1/N, and the phase difference of the clock before and after switching is further reduced to 1/N. As a result, by processing the digital signal with this output clock as the reference, the omission of data or the generation of overlapping can considerably be reduced.

Title: Vacuum cleaner
Inventor: SENDA NORIAKI
IPC: A47L9/28
Filed: 1999-04-16
Abstract: PROBLEM TO BE SOLVED: To provide a vacuum cleaner capable of reducing noise with a simple structure. SOLUTION: A suction slot is opened and a dust collecting room for collecting dust is sectioned on the negative pressure side of a motor fan housing for storing a motor fan 31 in a case. A pressure sensor for detecting the quantity of collected dust by detecting the negative pressure is disposed on the negative pressure side of the motor fan 31. A control means 51 for controlling the drive of the motor fan 31 drives/controls the motor fan 31 in a prescribed condition by the operation set by an operation means 52 of a connected hose.  Based on the detected negative pressure variable according to the quantity of dust, the same frequency as that of noise generated in response to the quantity of dust is outputted in the opposite phase and in a prescribed volume from a first speaker 41 disposed in the motor fan housing and from a second speaker 42 disposed in an exhaust room to off-set the noise. Therefore, noise can be easily reduced by utilizing the pressure sensor for detecting the quantity of dust, without a detecting means for detecting noise.

Title: Screen mask for screen printing
Inventor: ONOZAKI JUNICHI
IPC: B41N1/24
Filed: 1989-04-28
Abstract: PURPOSE:To attain satisfactory plate making property and to achieve printing wherein joint material becomes seldom insufficient at the time of joining and a bridge between adjacent joint patterns is hardly created by continuously piercing a cutting plate pattern over a plurality of adjacent joint patterns formed oblongly in a direction crossing the printing direction and providing a narrow part on a part corresponding to the interval between the joint patterns of the plate making pattern. CONSTITUTION:Since a cutting plate pattern 33a continuously pierced over a plurality of adjacent patterns 32 corresponds with the printing direction or an angle formed with the pattern and the printing direction is not at a right angle, the cutting plate making property of a joint material paste 22 is improved at the time of printing. Moreover, the paste printed between the adjacent patterns 32 is less, and this paste 22 is attracted to the joint patterns 32 on a substrate 31. Therefore it is easy to cut in a narrow part 34a when soldering is carried out, and accordingly it never remains as a bridge between the joint patterns 32 at the time of soldering.

Title: Automatic gain control circuit for optical receiver and amplifier
Inventor: ICHIKAWA AKIHIKO
IPC: H04B10/572
Filed: 1981-07-15
Abstract: PURPOSE:To permit use without reference to modulation systems by bringing the output of a preamplifier which amplifies a light input under automatic gain control on the basis of variation in DC component. CONSTITUTION:A light input converted by a photodetector 1'' is amplified by a preamplifier 2'', whose output is divided through a resistance R'' and the drain- source impedance of an FET11''. The DC potential VA at this division point is applied to an expander 9'' through a resistance R''2. Since the output of the expander 9'' controls the grid of the FET11'', AGC is exercised to compress variation in potential VA at the division point. Therefore, the AC component at the division point also corresponds to the impedance of the FET11'' and its variation is compressed to obtanin a stable output signal from an amplifier 10''. Thus, the AGC is exercised on the basis of variation in the DC component of the preamplifier output, so the control circuit is usable without reference to modulation systems.

Abstract: PURPOSE:To measure the capacitance between remaining two terminals and internal resistance, by electrically connecting one terminal of a MOS transistor to be measured to the chassis of an LCR meter at a ground potential, and connecting the remaining two terminals to the LCR meter. CONSTITUTION:An LCR meter 1 incorporates, e.g., an oscillator (OSC) 2, which oscillates and outputs 1MHz, an ammeter 3 and a voltmeter 4. The drain of a MOS type transistor 5 to be measured is connected to the OSC 2 and the voltmeter 4. The source is connected to the common connecting point of the ammeter 3 and the voltmeter 4. Whereas, the gate is connected to a chassis 6 of the LCR meter 1, which is at a ground potential. Thus, the capacitance between the remaining two terminals other than the gate, which is connected to the chassis 6, (i.e., between the drain and the source) and internal resistance can be measured. Therefore, the characteristics of the MOS transistor can be measured only by the LCR meter.
