Title: Stabilizer
Inventor: URUSHIYAMA YUTA
IPC: B60G21/055
Filed: 1997-05-07
Abstract: PROBLEM TO BE SOLVED: To attain high roll rigidity without sacrificing seating comfortableness by changing an apparent spring constant of a bar-shaped spring member to which a piezoelectric conversion element is stuck by changing impressed voltage on the piezoelectric conversion element by the bar-shaped spring member in which plate-shaped piezoelectric conversion elements are closely arranged at proper places. SOLUTION: Piezoelectric modules 4 are closely arranged on the outer peripheral surfaces of parts which are bent in an L-shape from the supporting point by left and right saddles 2 and are extended in the same direction. When a stabilizer rod 1 is going to bend at this stage, compressive stress is generated in the piezoelectric conversion elements(elements) of the piezoelectric modules 4 on a tensile side and tensile stress is generated in the elements on a compression side. Internal stress generated in the elements in this way acts in a direction that the bending of the rod 1 is suppressed and apparent rigidity of the rod 1 is increased.  When voltage is impressed on the elements, inclinations are changed at the parts on which the elements are provided, the angle of torsion at the other end becomes the same as that of a conventional product which is large in spring constant and sufficient roll rigidity is secured.

Title: Waveform discriminating device
Inventor: OBATA ATSUSHI
IPC: H03K5/1532
Filed: 1986-05-21
Abstract: PURPOSE:To decide the pripriety of a waveform of an electric signal by designating the period of a time base to be checked and the period of an amplitude axis and measuring the number of peaks and number of times passing its range. CONSTITUTION:In starting the measurement, a position controller 2 generates a position designation signal by a preset program. A level detection controller 3 generates a period signal from the position designation signal and inputs the signal to a level discriminating device 4. The level discriminating device 4 compares the number of pulses to be included in each designation period at every designation period and it is taken as 'good' when the number is coincident with the specified number and it is taken as 'no good' when the number is not coincident with the specified number. A peak discriminating device 7 compares the number of pulses to be included in each designated period at every designated period, and it is taken as 'good' when the number is coincident with the specified number and it is taken as 'no good' when the number is not coincident with the specified number.

Filed: 1988-05-16
Abstract: PURPOSE:To prevent mis-focusing and to improve the tracking to a moving object by driving and controlling a focusing member in a direction by a moving direction code selected by a selection means when a focus voltage is changed suddenly more than a reference value. CONSTITUTION:When a comparator 8 detects a sudden change in a focus voltage A, its output signal rises from L to H. Moreover, the phase of a level vibration component B is disturbed by the sudden change in the focus voltage A and a direction discrimination circuit 11 applies erroneous direction but it is interrupted by switches 17, 18. While an output signal of a latch circuit 15 is at H, a motor drive circuit 20 drives a pulse motor 21 based on the moving direction data read from the direction memory 12. Then the master lens 2 is moved while it is vibrated in a direction set before the sudden change in the focus voltage A succeedingly. When the focus voltage A is made stable, the level vibration component is made stable within one period of a timing signal E.

Abstract: PURPOSE:To speed up the restart of processing of a computer system by discriminating whether backup is normal or not just after reconnection of electric power supply. CONSTITUTION:If an AC input is broken, an output from a battery 2 is supplied to an output voltage controlling circuit 5 through a diode 3b and a switch 4.

The latch type relay 8 keeps its status also after breaking its driving current. At the time of returning the AC input, DC voltage is restored through a rectifing circuit 1 and each circuit is returned to the ready status. Just after the restoration, a CPU 10 reads out the status of a relay contact 9 through a controlling part 12 of a semiconductor storage device 11 and discriminates at the time of opening or closing the relay contact 9 in the backup state of the battery is as normal or as abnormal, respectively.

Filed: 1982-07-06
Abstract: PURPOSE:To drastically simplify an external circuit of memory IC by comprising, within a memory IC, a power source voltage detecting part and a switching part which outputs chip selection signal levels through the changeover operation. CONSTITUTION:The signal at an input terminal 21 of chip enable signal (chip selection signal) CE is applied to a power source control buffer circuit 23 through an inverter 22. Namely, after passing a buffer circuit, the signal CE controlled by the power source voltage VDD is transmitted to each part. When the power source voltage VDD is higher than the breely set voltage Vx which is lower than the operating voltage range of memory, the buffer circuit 23 allows the signal level ''0'' or ''1'' of the signal CE to pass. However, if the power source voltage VDD becomes lower than the setting voltage Vx, a memory IC enters inoperative condition.

Title: Air conditioner
Inventor: MATSUKI YOSHITAKA
IPC: F24F7/007
Filed: 1998-04-27
Abstract: PROBLEM TO BE SOLVED: To prevent an exhaust passing through a heat exchanger from causing a condensation of dew and a freezing in a severe winter season while preventing a smack of drafting by increasing exhaust capacity relatively greater as compared with air feed capacity to raise the temperature of the feed air introduced into a room as compared with the case where both the amounts of air are the same. SOLUTION: In this air conditioner 1, feed air with a feed air fan and an exhaust with an exhaust fan pass through a heat exchanger 21. The temperature of outside air is detected by a temperature sensor 24. When the temperature of the outside air falls below 5 deg.C, the rotational speeds of the feed air fan and the exhaust fan are controlled to relatively increase exhaust capacity relatively greater as compared with of feed air capacity. The rising range of the temperature of the feed air is enlarged as compared with the case where the exhaust capacity and the air feed capacity are the same to prevent a smack of drafting. When the temperature of the outside air falls below-10 deg.C, the feed air fan is stopped while the exhaust fan is operation at a low speed. Moisture is drained from a humidifying unit 3. This prevents freezing of the heat exchanger 21 and the humidifying unit 3.  The apparatus thus obtained is ideal for a full heat exchanger type heat exchanger.
