Abstract: PURPOSE:To facilitate manufacturing and processing and to reduce a cost, by a method wherein cooling of a sensor situated in the discharge duct of a microwave oven is performed through simple formation of a vent passage to collide against cleaned cooling air with the sensor without mounting a blast means for an exclusive use. CONSTITUTION:When a signal is outputted from a heater control circuit to a heater 7 to output the heater 7, the heater 7 generates heat to incinerate a contaminated material adhered on the surface of a sensor 6, and the sensor 6 restores detecting sensitivity. Thereafter when the heater 15 is caused to output to generate heat,closing bodies 16 and 17 receive heat from the heater 15 to change a shape. The closing body 17 is changed in a shape to bring it into a state to close a vent port 10, and the closing body 16 is changed in a shape to bring it into a state to close an exhaust duct 5. In this case, when a blast fan 12 is caused to output, external cold air comes, as shown by an arrow mark B, in a device body 12 through a suction feed port 11 and an air intake port 13. The air flows through a draft port 9 to the discharge duct 5 by means of an air intake port 14, a draft port 18, and a heating chamber 3, and is discharged through a discharge port 19. In this case, the sensor 6 is cooled.

Title: Data protection system
Inventor: HASHIMOTO MAKOTO
IPC: H04Q3/72
Filed: 1985-11-27
Abstract: PURPOSE:To prevent the invasion of noise occurred in the insertion time of the hot-line of a subscriber's circuit to an leading highway by connecting a capacitor which delays the leading of an output buffer to an output buffer input part in the subscriber's circuit. CONSTITUTION:An output buffer 6-000 is connected to an leading highway 7-0 with other output buffer and a wired OR by inserting the hot-line of the subscriber's circuit. At such a time, since the base input of a transistor 14 does not become an H level instantly by a capacitor 18 even when the base of a transistor 10 becomes the H level by the noise, the transistor 10 remains at an off state. When a charge in the capacitor 18 progresses, the transistors 10 and 14 are operated, and therefore, the connection state between the output buffer 6-000 and the highway 7-0 are formed. Thereby, the noise occurred in the insertion time of the hot-line of a package can be prevented from invading to the leading highway 7-0 from the buffer 6-000.

Filed: 1999-09-20
Abstract: PROBLEM TO BE SOLVED: To increase processing speed by reducing circuit scale. SOLUTION: These parallel computers are constituted of a quadrature shift register 6 and a memory 3, data is transferred to the quadrature shift register 6 with P bit width by an M step, the data is transferred (inputted/outputted) to the memory 3 with M bit width by a P step. Transfer in the reverse direction is also possible. The circuit scale is reduced by the transfer of the data by such bit slices. A processor array 1 and a buffer 4 are added to the parallel computers, the data is transferred from the memory 3 to the buffer 4 with the M bit width and at a stage that N bits are arranged in the buffer 4, the data is transferred to the processor array 1 with the number of steps of N/M. Thus, the number of steps for transfer is reduced and the processing speed is increased.

Abstract: PURPOSE:To efficiently perform re-input of error data by performing error check whether or not an update result is correct when an in-column text is updated, and suppressing the travel of a cursor when it is judged that the text is incorrect. CONSTITUTION:An input analysis means 13, after analyzing an instruction for a code inputted from a keyboard 11, returns it an editor control part 12. The editor control part 12 stores a column under edit in an edit target storage means 14, and delivers control to a text edit means 15 or a cursor travel means 16 corresponding to the instruction. The text edit means 15, after editing the content of the target column of a text buffer 19, displays it on a text display 20. The cursor travel means 16 shifts control to an error check means 18 when the content of an in-column text update storage means 31 is updated. When the text is incorrect, the error check means 18 stops the travel of the cursor by a cursor travel suppression means 32.

Filed: 1993-10-22
Abstract: PURPOSE:To make uniform the side face profile of a floating gate by not removing an anti-oxidation film but employing it, along with a selective oxidation film, as a mask in the etching process for forming the floating gate. CONSTITUTION:A first semiconductor film 23 and an anti-oxidation film are formed on a semiconductor layer 21. An opening is then made through the anti-oxidation film 24 and the surface of the first semiconductor film 23 exposed through the opening is thermally oxidized using the anti-oxidation film 24 as a mask thus forming an insulating selective oxidation film 28. On the other hand, the first semiconductor film 23 is etched using the anti-oxidation film 24 and a selective oxidation film 28 as a mask to leave the first semiconductor film 23, i.e., a floating gate, under the selective oxidation film 28. Furthermore, a control gate 31 is formed at least above the selective oxidation film 28 and on the side part of the floating gate 29 through a second insulation film 30 thus forming impurity diffusion regions 32, 33 on the semiconductor layer 21. This method allows formation of a floating gate 29 having stabilized side face profile.

SOLUTION: The locking structure for a box 10 fitted with cover is constructed in a push-open type structure, and with a pressing part 46 for a locking member 34 provided at a door 18 pressed, the door 18 itself and a cushioning material are elastically deformed. By displacing a swing center shaft 42 of the locking member 34 toward the front, utilizing the deformation, engagement of an engaging claw 48 with a part 50 to be engaged is disengaged and the engaging claw 48 is retreated in the direction of door opening and thereby the door 18 is opened. Therefore, the structure can be simplified as compared with a locking structure of a conventional push-open type wherewith locking is released by converting the direction whereon the load is applied.

Title: Image forming device
Inventor: OKADA NAOHIRO
IPC: G03G15/08
Filed: 1990-10-02
Abstract: PURPOSE:To satisfactorily perform reversal development of toner from a developing device to the electrostatic latent image on the surface of a photosensitive body without applying a bias voltage to a developing electrode by specifying the extent of electrification of toner supplied to the developing device to apply the bias voltage to the developing electrode. CONSTITUTION:Toner preliminarily electrified with a high specific electric charge, concretely, toner adjusted to the range of + or -(15 to 23)muC/g electrification extent is supplied as toner T stored in a development vessel 4B of a developing device 4. When toner whose extent of electrification is adjusted to this range is supplied to the developing device 4, toner T is electrified with high specific electric charge by frictional-electrification to carrier C in the development vessel 4B. The same potential as the bias voltage is given to the sleeve surface of a developing roller 4A by the electric charge held in this electrified toner T though the bias voltage is not applied to the sleeve surface. Thus, a toner image of sufficient density is formed on the electrostatic latent image of a photosensitive drum 1 without the bias voltage.
