Title: Comparator with latch
Inventor: FUNAHASHI MASAHIRO
IPC: H03M1/36
Filed: 1988-07-04
Abstract: PURPOSE:To prevent the output of a comparator from fluttering at every clock even if an input voltage is equal to a reference voltage by giving a hysteresis characteristic to the action of the comparator with latch. CONSTITUTION:A prescribed little current is caused to flow in the base of a transistor Q7 by a bias voltage VB and the prescribed current is caused to flow in a collector, whereby a system is prevented from being completely turned off. Thus, the output voltage of the OUT terminal of the comparator with respect to the voltage VIN shows a hysteresis action when the input voltage VIN is raised and is dropped. With the hysteresis characteristic, the voltage VIN is almost equal to the reference voltage VREF, the change of the output voltage in the comparator is delayed by the shifted amount of the voltage of hysteresis even if the size relation of VIN and VREF is continuously exchanged at every period of the clock, whereby the output of the comparator is prevented from fluttering.

Title: Suction system of diesel engine
Inventor: NAKAMURA SABURO
IPC: F02B3/06
Filed: 1989-06-29
Abstract: PURPOSE:To raise further the suction gas temp. by furnishing a differential pressure valve, which is opened when the pressure understream becomes a certain width smaller than the pressure upstream, at a point on an intra-head bypass in the neighborhood of a suction port. CONSTITUTION:An opening/closing valve 15 is shut when the engine concerned is operating at a low revolving speed. At this time, a differential pressure valve 26 remains closed until the pressure in a suction port 11 sinks sufficiently even though a suction valve 12 is in opened condition. When inside the suction port 11 gets a sufficiently large neg. pressure, the differential pressure valve 26 is opened. From a bypass B, consequently, the suction gas is supplied to the cylinder at one time through utilization of large differential pressure to cause a raise of the suction gas temp. due to diabetic compression. At this time, the differential pressure valve 26 is located sufficiently close to the suction valve 12, and the capacity is lesser between these two members 26, 12, so that the diabetic compression is conducted effectively to allow rise of the suction gas temp. to a great extent. In addition, the suction gas passing through the bypass B is heated previously by the heat possessed by the cylinder head 2, and the suction temp. is accordingly raised furthermore.

Title: Corona transfer device
Inventor: MURAI YUTAKA
IPC: G03G15/02
Filed: 1987-07-08
Abstract: PURPOSE:To execute the stable transfer of a toner image from the time of moisture absorption of a transfer material to the time of drying by making it possible that the distance of the corona discharge wire of a corona discharger to the surface of an image carrier can be altered according to the surface resistance of the transfer material. CONSTITUTION:When the toner image 2 is transferred on the transfer material 3 whose surface resistance lowers because of the moisture absorption, a solenoid 25 is turned on and a plunger 26 is attracted. Then, a cam axis 20 rotates counterclockwise through a lever 23 and a common shield case 10 rotates counterclockwise by a cam 21 centering around a pin 16 while compressing a spring 19. The transfer corona discharge wire 9 approaches the surface of the photosensitive drum 1 and gives a strong corona discharged charge to the back surface of the transfer material 3. And a destaticization corona discharge wire 12 gets away from the surface of the photosensitive drum 1 and prevents the charges from decreasing by influencing the charge for transfer in the transfer area with a AC corona. Thus, electrifying action by the transfer corona discharge is raised, the destaticizing action by the destaticization corona discharge is weakened and the shortage of the transfer charge in a transfer area can be prevented.

Title: Writing/collating device for face information
Inventor: KASUYA SHUJI
IPC: G06T7/00
Filed: 1989-06-30
Abstract: PURPOSE:To attain the accurate collation of face information regardless of the direction and the intensity of light quantity or the physical condition by reducing a primary image to specify the positions of the whites of eyes and using these positions as the important information sources of a face. CONSTITUTION:When a primary image is reduced by an image reduction means 6, the density of the picture element forming the image is increased and the black parts are blackened more. Thus the boundaries between the whites of eyes and their ambient parts are made clear. Then an eye's X-Y coordinate specifying means 9 specifies the X-Y coordinates of the whites of eyes where the boundary between the white color and other parts is made clear. A face element position measuring means 10 specifies the X-Y coordinates of the face elements except the eyes based on the specified X-Y coordinates of eyes. Thus it is possible to perform the collation between the input information and the personal information stored previously regardless of the change of the light quantity and the change of the physical condition.

IPC: G09G3/04
Filed: 1988-07-08
Abstract: PURPOSE:To certainly read information by providing a displaying function with which successively displayed information groups can be distinguished visually from other information groups whenever plural information groups are switched. CONSTITUTION:For example, seven segments X and another seven segments X larger than the segments X are formed of a transparent electrode material on a glass base plate, with the segments X and Y having the same center position. By using a liquid crystal display having such two kinds of character sizes the character size is switched when the display of the current value is switched to the display of a pointer of a meter. Thus a displaying function with which successively displayed information groups can be distinguished visually from other information groups whenever plural information groups are switched is provided. Since both displaying pictures can be distinguished from each other at the time of inspecting a meter, wrong reading of the meter can be eliminated and the operability of this display device can be improved.

CONSTITUTION:A pedestal made of an insulator to have a recessed part at the center is provided at the bottom part of a housing 2. Further, a lower electrode 7 is stuck on the bottom part of the recessed part. Further, the dielectric powder 6 is charged between an upper electrode 5 and the lower electrode with such a density that the dielectric powder 6 is in mutual gentle contact. A voltage is applied across the upper electrode 5 and lower electrode 7 through lead wires (a) and (b) to apply the bias electric field to the dielectric powder 6. When a diaphragm 3 is vibrated with a sound, its vibration is transmitted to the dielectric powder 6 through a presser 4 and the dielectric powder 6 deforms to vary in contact area. Here, the quantity of the electric flux passing through the dielectric powder 6 varies. The voltage between the lead wires (a) and (b) or current flowing through them, therefore, varies and the sound is transduced into an electric signal.
