Abstract: PURPOSE:To prevent the deterioration in high frequency characteristics by providing a plurality of contact holes respectively at both ends of a resistance that is formed at a semiconductor board and connecting aluminum wiring regions through a plurality of these contact holes. CONSTITUTION:One end of a resistance 1 is connected to an external terminal pad 3 by aluminum wiring 4a through the 1st, 2nd, and 3rd contact holes 2a, 2b, and 2c. Further, the other end of the resistance 1 is connected to an IC internal circuit through a contact hole 2d. In the case of static electricity which is impressed to the external terminal pad 3, consequently, an electric charge is discharged over the broad area including the contact holes 2a, 2b, and 2c and field concentration is relieved in comparison with a case where the electric charge is discharged onto an area having only a contact place and then, electrostatic breakdown strength can be improved.

Abstract: PURPOSE:To perfectly perform a report by using sound in an electronic register which generates sound in accordance with input information, by increasing the sound generating speed when input information is generated quickly and abundantly. CONSTITUTION:Amounts of money and quantity are inputted through a ten-key 1 and item groups are inputted through a function key 4. Memory 7, display 9, and printing 10 are performed by a CPU 3 according to the program of an ROM 31, and the CPU 3 drives a sound generating circuit 32 through a decision means 11 and a sound buffer 12 and a speaker 23 utters input information, such as received amount, sold amount, amount of change, etc. Whenever a detecting means 24 detects completion of sound, the means 24 sends a signal to a decision means 26 through a sound processing pointer 25. On the other hand, the sound information judged by the decision means 11 is inputted into the decision means 26 through a sound buffer pointer 13. The decision means 26 decides the accumulated conditions of the sound information from the input of both the pointers 13 and 25 and adjusts the uttering by driving one of high-speed, medium-speed,  and low-speed process signal generating sections 27-29, and thus, the discontinuation of the uttering is prevented.

Filed: 1993-08-30
Abstract: PURPOSE:To enhance the dust collecting performance of a floor nozzle by providing high voltage electrodes for dust collection, which are opposed to each other, in a floor nozzle body for sucking up dust from a surface to be cleaned. CONSTITUTION:A pair of high voltage electrodes 33 to which a high voltage is applied from a high voltage circuit is provided in a lower body part 24 of a floor nozzle body 21.

Filed: 1984-10-11
Abstract: PURPOSE:To enable to make various controls without giving any influence to the sound signals, by recording the control signals, overlapping on the sound channel, which has frequency composition other than the frequency band of sound signal. CONSTITUTION:30kHz is chosen as a frequency of control signal, and it is recorded beforehand, after being FM modulated, at a specific position overlapping with the sound signals. Sound FM signal inputted to an input terminal 1 is sent to a band bus filter 2 where specific frequency bands are separated and supplied to an FM demodulation circuit 3. Sound signals and control signals are demodulated here, but by going through a low pass filter 4, only sound signal component of 20kHz or less is guided to an output terminal 5. On the other hand, only control signal of 30kHz is selectively amplified by a tuning amplifier 6 and inputted to a detective circuit 7, and its detection output is guided to an output terminal 8. In this way, any specific control can be executed basing on the control signal thus detected.

Title: Creep prevention device for elastic rotary body
Inventor: SUGIYAMA TOSHIHIRO
IPC: G03G15/00
Filed: 1993-08-30
Abstract: PURPOSE:To eliminate occurrence of creep in an elastic rotary body by detachably interposing a spacer composed of a material having higher rigidity than the elastic rotary body, between a contact part. CONSTITUTION:An elastic rotary body which is required to uniformly contact with a contact counterbody 1 with elastic deformation is provided in such a way of opposedly contacting with the contact counterbody 1 at a prescribed contact pressure. A sheet spacer 4 is detachably interposed between the contact part 3 of the contact counterpart 1 and the elastic rotary body 2. The spacer 4 is a thin matter formed of a material having higher rigidity than the elastic rotary body 2. Stress expressed by the stress lines 5 acts on the elastic rotary body 2, because the contact counterbody 1 and the elastic rotary body 2 are contacted with each other at the prescribed pressure. Intervention of the spacer 4 between the contact part 3 expands the stress acting region, makes the stress easy to distribute, and eases stress concentration, so that creep generation is suppressed. In forming an image, the spacer 4 is removed.
