Title: Synchronous rectifying circuit and power supply unit
Inventor: MIKAMI HITOSHI
IPC: H02M7/21
Filed: 1999-11-30
Abstract: PROBLEM TO BE SOLVED: To provide a synchronous rectifying circuit and a power supply unit capable of improving power supply efficiency over light load to heavy load conditions. SOLUTION: When a MOS-FET12 is turned on by a control signal from a control circuit 20, current supplied from an input power supply is outputted to a load 30 while charging a capacitor 22 through a choke coil 16. When the MOS-FET12 is turned off, commutating current passing through the capacitor 22 and the load 30 flows through detecting resistors 31, 32. Comparators 38, 39 compare the detected voltage with reference voltage, and drive MOS-FETs 18, 19 when the detected voltage is higher than or equal to the reference voltage. Only the MOS-FET 18 is turned on when the commutating current is low, and both MOS-FETs 18, 19 are turned on when the voltage supplied to the load 30 is higher than or equal to its rating. It is thus possible to improve the power supply efficiency over the light load to heavy load conditions.

Filed: 1997-12-11
Abstract: PROBLEM TO BE SOLVED: To prevent a personal computer being a suspended state for saving power consumption from being started at the time excepting of resperating it by providing a means for interrupting a mouse operation signal generated by oscillation at the time of not operating so as not to be transmitted to the personal computer. SOLUTION: A personal computer main body and a mouse 104 are connected through a cable 103 and a switch 201 for interrupting the mouse 104 and the personal computer main body at the time of not operating is fixed to the rear surface of the mouse 104. Then, a moving quantity sensing member 202 sensing the moving of the mouse 104 senses slight oscillation and informs the personal computer main body of the moving through the cable 103. As the result, a clock signal line on the side of a personal computer side and a clock signal line on the side of a mouse main body is interrupted at the time of not operating the personal computer to avoid the transmission and reception of a signal, and a data signal line on the side of a personal computer main body and a data signal line on the side of the mouse main body are interrupted.  Thereby, data is prevented from being destroyed in the middle of processing.

Title: Open-showcase controller
Inventor: NAKAMORI MASARU
IPC: F25D11/00
Filed: 1998-12-02
Abstract: PROBLEM TO BE SOLVED: To enable an open-showcase controller to inexpensively make data transmission with a central device. SOLUTION: A system controller makes an output request in order to know the state of each open showcase. The output request is converted into a video signal by means of a center MODEM 2 and the video signal is sent to a video converter 4 through a coaxial cable 3. Then the video signal is sent to a plurality of open showcase controllers 6 after the signal is demodulated by means of a MODEM 5. Upon receiving the output request, the open-showcase controllers 6 discriminate the present states of the open showcases from the output signals of sensors 7, etc., and send the data to the video converter 4 in the form of serial signals. The converter 4 converts the serial signals into video signals by means of the MODEM 5 and send the video signals to the center MODEM 2 through the coaxial cable 3 and the MODEM 2 sends the video signals to the system controller 1 after demodulation.  Therefore, the controller 1 can know the state of each open showcase.

Title: Touch probe
Inventor: NAKAKAWARA HIDEMITSU
IPC: G01B17/00
Filed: 1993-12-15
Abstract: PURPOSE:To prevent the generation of a malfunction by correcting mechanical resonance frequency to the frequency of a high-frequency electric signal coinciding with the mechanical natural frequency of an ultrasonic vibrating horn on the basis of the state of resonance detected. CONSTITUTION:When a filler 3 is ultrasonic-vibrated by mechanical resonance frequency by using a piezoelectric element 7, vibrations at an end sphere 3 are maximized, and the vibrations of the filler 3 are obstructed and the impedance of the element 7 is changed when the end sphere section touches with a surface to be measured. Consequently, the currents of the element 7 and the phase difference of voltage are varied, and the variation is sensitive to the presence and absence of the variation and a tough signal is acquired with high sensitivity. The phase difference is also altered even by the temperature change of the filler 3, but a variation and the time required for the change differ from the time of a touch. As a result, the phase difference of the currents and voltage of the element 7 is monitored periodically, and the mechanical resonance frequency is corrected to the frequency of a high-frequency electric signal coinciding with the mechanical natural frequency of an ultrasonic vibrating horn 1 on the basis of the variation of detected phase difference and the time required for the variation. Accordingly, resonance frequency is corrected automatically, thus preventing the generation of a malfunction.
