Title: Inverter device
Inventor: YAMASHITA TAKESHI
IPC: H02M1/08
Filed: 1995-07-07
Abstract: PROBLEM TO BE SOLVED: To lessen a switching loss even when the voltage of a DC power supply fluctuates. SOLUTION: Transistors 13, 14 control a gate of a MOS-input type semiconductor switching element 2a. MOSFETs 29, 30 are serially connected to the transistors 13, 14 respectively through gate resistors 19, 20 and the voltage of a DC power supply of an inverter device is detected by a voltage detecting circuit 24. The MOSFETs 29, 30 are turned off when the detected voltage is higher than a specified level and they are turned on when the detected voltage is lower than the specified level. When the voltage of the DC power supply is high, the gate of the semiconductor switching element 2a is charged by charging resistances of resistors 44, 19, 21 and discharged by discharging resistances of resistors 21, 20, 45, and therefore charging and discharging speeds are slow.  On the other hand, when the voltage of the DC power supply is low, the gate is charged by the charging resistances of the resistors 19, 21 and discharged by the discharging resistances of the resistors 21, 20, and therefore charging and discharging are done rapidly and there is only a small switching loss.

Filed: 1995-06-14
Abstract: PURPOSE: To correctly detect a picture boundary area based on pseudo gradation picture data by discriminating whether or not a picture element to be detected constitutes the boundary area based on detected picture difference. CONSTITUTION: When pseudo gradation picture data is inputted, a density difference detecting part 2 outputs density difference data concerning the picture element corresponding to respective kinds of pseudo gradation picture data to a halftone picture data converting part 4. Then, a converting part 4 permits a halftone converting RAM6 to store pseudo gradation picture data and also makes pseudo gradation picture data which is stored in a picture element area with the object picture element as a center into a block. Then, the filter coefficient of a spatial filter is read from ROM5 based on density difference data inputted from the detection block 2 so as to execute spatial filtering. Then, a picture element density converting part 7 converts picture element density by executing linear interpolation by a projecting method.  After that, a pseudo gradation picture data converting part 8 converts halftone picture data where picture element density is converted into new pseudo gradation picture data.

Filed: 1986-07-23
Abstract: PURPOSE:To attain automatic decision of the kind of appearance signal by providing a comparator circuit forming a discharge path for a capacitor and a voltage detection circuit detecting the appearance of one AC signal in a capacitor. CONSTITUTION:The holding voltage of a capacitor 9 charged from a positive power supply via a resistor 10 rises only for a period an output of a NOR gate 8 rises at a high level as shown in voltage waveform (g) as the charging is progressed and descends as the discharge is progressed in other period.

On the other hand, no magneto-optic signal is fed to the input terminal 1 and a CD signal is fed to an input terminal 2, then a low level signal representing the appearance of the CD signal is outputted to the output terminal 12 from the inverter 11. Thus, the kind of appearance signal is decided automatically.

Accordingly, since power for driving the motor is supplied from the battery, electromagnetic noise, heat generation do not occur, and electromagnetic noise suppression remedy, heat generation remedy are not required. Since charging is conducted by a small current at the time of non-driving the curtain, a power transformer may have a small size and a light weight, and the driver can be reduced in size and weight.

Abstract: PURPOSE:To manufacture such a slide member that keeps no stress moment on a sliding surface as well as to secure a stable mechanical seal, by making up the seal so as to delicately check any deformation of the sliding surface after shrinking a seal ring into a retainer and cooling it. CONSTITUTION:A taper angle theta of a taper fitting wall 10 is 0.5-5.0 or so, and when different in the coefficient of expansion between a seal ring 1 and a retainer 3 is small, the taper angle is set to be small but when it is large, it should be set to be large as well.

With thermal constriction in the retainer 3 following this cooling, the ring 1 is gradually constricted by the wall 10 and finally the ring 1 and the retainer 3 both are uniformly constricted tight at a fitting area whereby a sliding surface 2 is in no case deformed or tilted. Thus, a stable mechanical seal can be secured.

Title: Capacitance-type rotary-angle detector

IPC: G01D5/24
Filed: 1992-07-01
Abstract: PURPOSE: To obtain digital angle information of high analytical degree and constant precision in a wide temperature range and a mechanical load by a method wherein respective carrier disks are mutually guided by a spacer pressed in parallel to a rotation axis. CONSTITUTION: Fixed medium disks 28, 27 support a spoke-like pattern of an electrode on the back face 30 and a front face 31, respectively. In response to a rotation position of a disk 2 for an electrode pattern on the disk 28, a different capacitance occurs in connection with superimposition. Capacitance must be increased so as to detect a spontaneous capacitance by a current of an IC 32 without hindrance, and therefore an inner peripheral interval 33 is required to be reduced and make constant. For this reason, a spacer 37 is disposed between disks 27 and 28 apart from a rotation axis 36, and vibration movements due to abrupt rotation and large acceleration of the disk 27 and a displacement in an axial direction due to heat are suppressed.  An axial sliding bearing 31 is provided on the axis 36 or at a small interval in this spacer 37, and a spring stand 18 presses a rotor 23 to position with respect to the spacer 37 in an axial direction.
