IPC: G06F17/21
Filed: 1989-03-08
Abstract: PURPOSE:To reduce the workload of a user to a large extent to make a printing result legible by conducting a 'same data omission method' wherein when the same data continues two or more lines on an item of a sort key for comparing set data, the data for lines other than the first line is changed to a space to be printed. CONSTITUTION:With a table format printing key inputted from an input device 101, a table format printing start signal is transmitted, and a CPU 102 starts a table format printing program (201). The table format printing program executes an image plane display program, thereby displaying a sort key item assignment image plane on an image plane through a display device 106 and setting a sort key and a tabulation function key respectively to an item for conducting the sorting of data and an item for conducting a calculation for the sorting (202). After the completion of the setting of the sort key and the tabulation function key, an execution key is inputted, whereby a printing format setting program and a printing condition setting program are executed. The printing condition setting program assigns 'same data omission' using a ten key of the input device 101 (203). The assigned command is displayed on the image plane and simultaneously set to a printing management table 104. After all input operation is completed, the execution key is inputted (204).

Title: Recording method
Inventor: MOCHIZUKI NOBUO
IPC: G03G15/32
Filed: 1981-04-10
Abstract: PURPOSE:To facilitate the holding of a gap between a recording material and a stylus electrode and the cleaning, by using a dielectric film, where a minute ruggedness is provided in the front surface and many minute conductive parts insulated from one another are provided on the back surface, as the recording material. CONSTITUTION:A minute ruggedness 8 is formed on the surface of a dielectric film 7, and minute conductive parts 9 insulated from one another are buried on the back surface, and the back surface is smooth. This dielectric film 7 has the surface 8 charged uniformly positively and has minute conductive parts 9 on the back surface charged uniformly negatively by a corona charger 20. The printing process due to a stylus electrode 10 and a conductor roller 11 is performed to form a latent image corresponding to the print. When the latent image is developed by a toner 16 having a negative charge, the toner 16 is not stuck to minute conductive parts 9 having the negative charge, but the toner 16 is stuck to minute conductive parts 9 having no charge, and thus, a required image is developed, and the developed image enteres into the transfer process.

IPC: H04N5/91
Filed: 1987-03-11
Abstract: PURPOSE:To quickly attain phase synchronization by adding a burst signal at an optional desired position during one to several horizontal scanning periods before the first video signal after head changeover. CONSTITUTION:A video signal input is fed to a time base compression circuit 11 at first by a memory and the time base is compressed to a degree where the signal is inserted at a period being several times of the horizontal scanning period by using a clock generated by a clock generating circuit 12. Then a buffer period being several times of the horizontal scanning period is provided as the overlap period for head changeover before and after the changeover position of two video heads 30A, 30B. A burst signal is added to a part or most of the video signal period by using a buffer line addition circuit 13 during the overlap period. Thus, even when the head is switched on the way of horizontal scanning period, the phase synchronization is taken quickly.

Filed: 1989-03-06
Abstract: PURPOSE:To increase the test operating frequency by connecting a 1st clock signal inhibit circuit to an N-channel transistor(TR) in a latch circuit and connecting a 2nd clock signal inhibit circuit to a gate of a P-channel TR. CONSTITUTION:When a level of a TEST signal is logical '1' and a level fed to a data terminal is logical '0', and logical '1', the voltage of a capacitor 5 is respectively ¦VTP¦ and 5V-VVN (TTN is a threshold level of a TR 1) and the holding voltage is deteriorated. As a result, the holding time is also reduced. When the level of the TEST signal is selected to be logical 1 in the case of testing the holding characteristic of a latch circuit, a product with a deteriorated holding characteristic is excluded even with the high test frequency.

IPC: G03B27/32
Filed: 1991-03-19
Abstract: PURPOSE:To improve workability by automatically discriminating a picture frame of different size, provided mixed in a photographic film, and omitting work for deciding the frame size by an operator. CONSTITUTION:A frame size deciding part 150 is constituted by arranging nine transmitting type concentration sensors 152 in a direction orthogonal to a conveying direction of a negative film 12 to respectively detect transmission concentration along a width direction of the negative film 12. In a memory of a control part 154, a corresponding data to base concentration of the negative film 12 is previously stored to compare a supplied detection value with this base concentration data. That is, in the case of a full size picture frame, all the concentration sensors 152 are within a picture region, so that transmissive concentration of the sensor is low detected, and in the case of a panoramic size picture frame, the transmissive concentration of three upper/lower of the concentration sensors 152 is equalized to the base concentration. As a result, in the control part 154, the present detected picture frame can be discriminated for whether it is in the full size or the panoramic size.

When the running noise level detected is compared with the switching level preset at the switches 8, 14, and the signal 6 performs this switching and gain adjustment is made to the adjuster 12 according to the noise level. Accordingly, the driver can enjoy the listening signal pleasantly and safely.

Title: Refrigerator
Inventor: ANDO TOSHIAKI
IPC: F25D21/08
Filed: 1998-03-06
Abstract: PROBLEM TO BE SOLVED: To make the defrosting operation of a refrigerator at appropriate timing. SOLUTION: A refrigerator reads the temperature detected by means of a temperature sensor for cooler (P1) and discriminates whether or not the detected temperature is equal to or lower than a prescribed temperature set at -35 deg.C (P2). When the detected temperature is >-35 deg.C, the refrigerator returns to its main program without defrosting. When the temperature is <=-35 deg.C, the refrigerator turns off a compressor, a fan for cooler, and a fan for compressor, and turns on a defrosting heater (P3). Consequently, a cooler is heated and frost is melted. When the temperature detected by means of the temperature sensor for cooler becomes >=+13 deg.C thereafter, ('Yes' in P5), the refrigerator turns off the defrosting heater (P6) and returns the compressor, fan for cooler, and fan for compressor to the control pattern of normal cooling operation (P7).
