Title: Mode switching method in test mode of radio communication equipment
Inventor: YUASA KAZUTADA
IPC: H04B7/26
Filed: 1993-04-15
Abstract: PURPOSE:To prevent the confusion due to a setting error and the loss of a short plug by automatically performing a mode switch by using the slave machine of a cordless telephone set, utilizing the installation and non-installation state of the slave machine with a master machine and without using the short plug. CONSTITUTION:The comparator 15 of a master machine 1 fetches voltage VA and VB that each voltage of the B terminal of a power source Vcc and the A terminal of a charging terminal 17 is divided by resistances R1 to R5 in + input and - input of an AMP 1 and compares them. In this case, voltage VA>VB or voltage VA<VB is depending on whether a slave machine 2 is in the setting or non-setting state to the master machine 1 and an AMP 15 imparts a signal L or H to a master machine microcomputer 14. By this signal L or H, the microcomputer 14 controls each circuit in the internal part of the master machine so as to set a test mode A or B. Thus, the switching of the test modes A and B is automatically performed without the switching setting of a changeover switch and a short plug and a confusion due to a setting error and the loss of a short plug can be prevented.

Filed: 1986-04-18
Abstract: PURPOSE:To enhance the resolving power of an image to a submicron order, by a method wherein a wedge plate is allowed to stepwise move to a direction right-angled to an optical axis in a light path and the difference between the brightness signals of microscopic TV monitor images before and after the movement is operationally processed. CONSTITUTION:A wedge plate 8 is provided so as to be adjacent to a beam splitter 3 and stepwise moved through a piezoelectric element 9. The light of a light source 1 is reflected by the splitter 3 to irradiate a specimen 7 and the reflected light passes through the splitter 3 and is refracted by the plate 8 to generate lateral shift corresponding to the moving quantity of the plate 8 and formed into an image on a solid-state TV camera 13. The minute lateral shift quantity on the formed image is reduced to 1/n of picture element to obtain a differentiated picture element. Next, the brightness signals of TV images on one scanning line before and after the movement of the plate 8 are taken in a signal processing circuit 15 and the difference between two signals is operated and an initial differential signal value is added to the operated value to successively calculate a differential brightness signal to store the same. After this brightness signal is calculated with respect to the entire region of the measuring surface of the specimen 7, a bright and dark magnified image corresponding to the differential brightness signal can be displayed on the monitor TV 16.

Title: Electrode plate blank and electrode plate for display device
Inventor: FUKUYOSHI KENZO
IPC: G02F1/1343
Filed: 1988-04-11
Abstract: PURPOSE:To lower a specific resistance of an electrode, and also, to form a satisfactory pattern by setting the quantity of tin oxide of an ITO film of a transparent electrode plate blank to 6-9 weight %, and also, raising the degree of orientation of the (222) surface of an ITO crystal. CONSTITUTION:The quantity of tin oxide of an ITO film of a transparent electrode plate blank is set to 6-9 weight %, and also, the degree of orientation of the (222) surface of an ITO crystal is raised. When the quantity of tin oxide in the ITO film exceeds 10 weight %, sharpness and a shape of a pattern by etching are deteriorated, and it becomes difficult to form a minute pattern of <=100mum. On the other hand, when the quantity of tin oxide is smaller than 6 weight %, a value of a specific resistance becomes large. In such a way, since a specific resistance of an electrode can be lowered, and also, the degree of orientation of the (222) surface has been raised, in case this blank has been brought to etching, a satisfactory pattern shape can be formed.

Filed: 1990-04-03
Abstract: PURPOSE:To reduce the nipping width and reduce the deflection of the feed quantity by setting the folding place by a folding roller, at the place corresponding to the folded parts on both the sides of a cylindrical film. CONSTITUTION:A rectilinear roller 8 which is arranged in the direction crossing at right angle with the feed direction of a cylindrical film A and a folding forming pressing roller 11 which is arranged in parallel, nipping the cylindrical film A, to the rectilinear roller 8 and has the position 11b corresponding to the folded part of both the side edges of the cylindrical film A formed to a large diameter are installed in a feeding passage for the cylindrical film A whose both side edges are folded inside. Only the part corresponding to the folded part (a) of the cylindrical film A is nipped by the rectilinear roller 8 and the folding forming roller 11, and is sent out. Accordingly, since the nipping width is reduced, and only the folded part (a) having a uniform thickness is nipped, the driving power of the roller 8 can be transmitted uniformly, and the meandering of the cylindrical film A and the generation of creases can be prevented.

Title: Reversible control device for dc motor
Inventor: YOSHIDA YOSHIYUKI
IPC: H02P7/00
Filed: 1979-07-12
Abstract: PURPOSE:To stably control a motor at constant speed by regulating the frequency per one revolution of a motor of the detected pulse of pulse detecting means or the frequency of a clock signal and processing a digital signal at the gain of the control voltage of the motor. CONSTITUTION:When the first clear pulse P2a is applied to a counter C, the counter C clears the counted value. When load pulse is subsequently applied to the counter C, it starts counting the clock signals P1. When a motor A is rotated, the counter C receives a signal P1 through a NAND gate by the command signal from a command signal forming circuit to count up and to sequentially feed it to a latch circuit E. When the counter C receives the second clear pulse P2b to become the timing of the circuit E and to sample-hold the counted value thereof to convert the output from the circuit E into D/A conversion. Since the frequencies of the pulses P2a, P2b are proportional to the rotating speed of the motor A, the output of the D/A converter F is applied to the drive circuit G, thereby controlling the motor A stably at constant speed.
