Title: Method and device for recognizing image abnormality
Inventor: OTSUKI AKIRA
IPC: G08B21/10
Filed: 1992-06-11
Abstract: PURPOSE:To selectively extract image abnormality by simple image processing and to detect its cause. CONSTITUTION:A video camera 1 takes a picture for abnormality such as fire in a monitored area. The picture is digitized by an A/D converter 2 and the digital image is processed by an image abnormality detector 3. The detector 3 detects the abnormality of the image and outputs the detected data to a detected data distributor 4. The distributor 4 supplies a control signal S2 to a switch SW. On the other hand, the abnormality in the monitored area is detected by various sensors such as a fire sensor 6 and an illuminance sensor 7. Respective AND circuits A1 to A8 drive their corresponding alarms 14 to 21 for alarming fire detection, smoke generation and illuminance abnormality based upon the control signal S2 outputted from the distributor 4 and the various sensor output signals. Consequently the cause of the abnormal image recognized by the detector 3 can be identified.

The displacement of the position of this valve body and a reference position is calculated by CPU and the display signal corresponding to this calculation value is output to a display 14. Consequently the valve opening is made to display on the display 14.

Title: Time generator
Inventor: UCHIDA KATSUMI
IPC: G04G7/00
Filed: 1984-07-23
Abstract: PURPOSE:To enable correction smoothly following an external time, by selecting and correcting an output signal with normal and slightly different cycles from a clock pulse generator. CONSTITUTION:Time information 20-1 is set on a time receiving register 3 according to a signal from a timing circuit 4. Then, outputs of the register 3 and a time counting circuit 1 are subtracted separately with a subtractor 5 while detection signal for delay, coincidence or advance with respect to the standard time is inputted into corresponding flip-flops 8-10. The output thereof is further provided to open ANF gates 11-13 with which one of clock pulses (C1 with a bit longer cycle, normal C2 and C3 with a bit shorter cycle) outputted from a clock pulse generator 2 is selected and fed to the circuit 1 through an OR gate 14. This eliminates disturbance by an external clock pulse thereby assuring a stable operation.

Title: Dc/dc converter
Inventor: WATANABE SHIGEAKI
IPC: H02M3/07
Filed: 1983-08-22
Abstract: PURPOSE:To prevent the conversion efficiency of a DC/DC converter from decreasing by altering the connected state of a capacitor at the charging or discharging time in response to the value of an input voltage. CONSTITUTION:An input voltage level detector 7 detects whether an input voltage Vi is higher or lower than the preset prescribed voltage (reference voltage B). A switch connection controller 8 switches the switch group of a voltage converter 2 in response to the value of a detection signal (1 or 0) from the detector 7. When the switch group are switched, the connecting array of the capacitors at the charging or discharging time is altered. Thus, the decrease in the conversion efficiency due to the variation in the input voltage can be prevented.

Title: Printing method in thermal printer
Inventor: IWATA SATOSHI
IPC: B41J35/00
Filed: 1987-06-19
Abstract: PURPOSE:To prevent a sticking between a thermal head and a transfer ribbon, by a method wherein an electric current sufficient to melt a sticking part of the transfer ribbon to a heating element and insufficient to conduct printing is supplied to the thermal head after the completion of printing of each printing line and before a transfer paper is fed to a next printing line. CONSTITUTION:After the completion of a first line printing, a control part 2' successively supplies common pulses CM1'-CM4' to a timer circuit 9 at predetermined intervals at a time t2, which is just before a time t3 at which a platen 12 is driven, thereby successively generating conduction pulses C11'-C41' from the timer circuit 9 at predetermined intervals. In this manner, an electric current flows through a heating element connected to a NAND gate with '0' level output to heat it. The platen roller 12 is driven by one pitch during a period T4 from a time t3 after the generation of the conduction pulse C41' to a time t4. In this manner, a conduction pulse having a pulse width nearly insufficient to conduct printing is supplied to a heating element just before a transfer paper is driven by one step. Therefore, a sticking state between the heating element and the surface of a transfer ribbon is eliminated.

Title: Semiconductor memory device

Filed: 1995-06-20
Abstract: PURPOSE: To execute a required test by making a logic relationship of a data input terminal and a data output terminal when a test mode instruction signal is activated different from that when the test mode instruction signal is not activated. CONSTITUTION: At the time of a burn-in mode, a burn-in mode formation circuit 42 turns a signal BIM to a high level in accordance with a signal to a specific input terminal 34. In this state, a write data D fed from a burn-in device is reversed by an EXOR circuit 46 and written in a memory cell of a memory array 43 designated by an address via a write circuit 41. Then, under a predetermined control, the memory cell having the data written therein is selected and the data of the selected memory cell is read to a data output terminal 36 via a read circuit 44. Since the write data and read data are logically reversed in the burn-in mode, it is recognized that a semiconductor device 30 is operable in the burn-in mode if a logic disagreement of the data is detected by a comparator of the burn-in device.

Abstract: PURPOSE:To shorten the moving distance of a draw bar to provide a compact device by enabling a collet holding sleeve to be moved axially and forming a pressure chamber between the inner surface of sleeve and the outer surface of draw bar to supply pressurized fluid. CONSTITUTION:A collet 15 for clamping a tool pull stud 42 is held by a collet holding sleeve 16 in a spindle 11. Said sleeve 16 is axially movable and a draw bar 14 is provided with a pressurized fluid path 35. A pressure chamber 17 is formed between the inner surface of sleeve 16 and the outer peripheral surface of draw bar 14. When a tool is removed, the draw bar 14 is pushed out by a draw bar pushing piston 32 to loosen the engagement of a collet 15 with the holding sleeve 16. Then, pressurized fluid is supplied to the pressure chamber 17, and the collet holding sleeve 16 is moved axially so that the engagement of collet 15 with the sleeve 16 is completely released and the tool pull stud 42 is released from clamping by the elastic displacement of collet 15. Thus, the draw bar can do with the short moving distance.

Abstract: PURPOSE:To avoid the omission of picture elements by setting the picture element width at the end part of a line sensor at the value smaller than that at the areas excepting the end part of the line sensor. CONSTITUTION:Plural line sensors 18 are arrayed on a straight line, and the width of picture elements 1101 set at both end parts of the sensor 18 is set smaller (e.g. 1/2) than that of picture element 11 at the areas excepting both ends of the sensor 18. Therefore an amplifier having double gain is provided between the element 1101 and a gate 13. Thus an equal level is secured among signal outputs, and these outputs are sent to a transfer stage 14. Then it is possible to avoid the omission of picture elements while the width produced by recesses/projections 22 of a cut part of the sensor 18 is maintained.
