Title: Piezoelectric speaker
Inventor: HIROSHIMA YUKIMI
IPC: H04R7/12
Filed: 1999-05-19
Abstract: PROBLEM TO BE SOLVED: To provide a piezoelectric speaker whose frequency characteristics flat, in which a wide band can be reproduced, whose structure is simple and manufacture is easy by providing a circular piezoelectric element and a dome- like diaphragm which is stuck and fixed to the piezoelectric element formed in an almost semi-spherial form. SOLUTION: A dome-like diaphragm 1 is formed so that a polyether imido film becomes an almost spherical. Silver electrodes are installed in a circular ceramic piezoelectric element 2 and they are polarized in a thickness direction. The inner peripheral part of piezoelectric element 2 is kept by a frame 4 through an elastic body 3. The piezoelectric element 2 is fixed to the frame 4 through the elastic body 3 only on an inner peripheral side and it can execute an expansion movement in an almost free state without being restricted. Since the piezoelectric element 2 is in a circular form, expansion is generated in the diameter direction and it uniformly vibrates for a whole periphery.  The dome-type diaphragm 1 is stuck and fixed to the outer peripheral part of the piezoelectric element 2 and a sticking area with the piezoelectric element 2 can be enlarged and large amplitude can be taken out.

Title: Information display method using communication between two microcomputers of information storing/reproducing apparatus
Inventor: UEKI YASUHIRO
IPC: G06F13/00
Filed: 1994-05-27
Abstract: PURPOSE:To display information with a low cost and slow speed CPU by a method wherein the balanced processing is provided with an information mechanism microcomputer and an information key microcomputer and the mechanism microcomputer makes an access to a memory between a modulating/demodulating means and a compressing/expanding means in accordance with the instruction of the key microcomputer. CONSTITUTION:When a power supply is closed, a mechanism microcomputer 10 controls a servo circuit 11, etc., and reads TOC or UTOC out of a disc 28 and stores it in a key microcomputer 12. If a user selects the 3rd number with a key 13, the key microcomputer 12 selects its leading address. The mechanism microcomputer 10 receives this address and reads out the 3rd number and stores the information in a DRAM 17A through an RF amplifier, a modulating/demodulating means 15 and a memory control circuit 17B. Then the mechanism microcomputer 10 reads the information out of the DRAM 17A and subjects the respective predetermined block units of pieces of the information to an expansion treatment 16. The TOC is also stored in the DRAM. Only necessary bibliographical information is selected by the microcomputer 10 and supplied to the key microcomputer 10 and the communication is performed by every sector of a predetermined block time unit, so that the calculation and management can be easy and the two-microcomputer processing can be performed most reasonably.

Title: Floating point subtracting device
Inventor: ISHII HIDESHI
IPC: G06F7/508
Filed: 1983-07-27
Abstract: PURPOSE:To shorten an execution time and to improve performance by subtructing 1 from the least significant digit of the result of floating point subtraction when 1 is shifted out of the mantissa part of a subtracter during the digit matching of floating point subtraction. CONSTITUTION:An adder 10 performs arithmetic A+B'+C; B' represents the complement of 1 of B and C is a carry input to the least significant digit bit represented by a signal line 102. When 1 is shifted out of the mantissa part of a subtracter during digit matching, the output of the adder 10 is A-B-1, and when not, the output is A-B. When 1 is shifted out of the mantissa part of the subtracter during the digit matching, the signal line 102 is 0, namely, C=0, so that the output of the adder 10 is A+B'. This is equal to A-B-1.

Title: High drafting device in spinning frame
Inventor: NAKAHARA TEIJI
IPC: D01H5/00
Filed: 1979-10-25
Abstract: PURPOSE:A high drafting device in which the nipping point at the top edge of the apron is deviated from the nipping point at the front roller, thus removing the drafting fluctuation. CONSTITUTION:Sliver or rovings are drafted with back roller 2, middle roller 4 and front roller 5 to give spun yarns wherein the nippint point at the top edge of aprons 3a and 3b on the middle roller 4 is deviated in the vertical direction to the yarn path in regard to the nipping point at the front rollers 5-1 and 5-2. At the nipping point of the front rollers 5-1 and 5-2, the air is disturbed by the high-speed revolution of the upper and bottom front rollers to cause the fiber disturbance, resulting in the yarn fluctuation. However, when the nipping point at the top end of the aprons 3a and 3b is shifted to the side of the front roller 5-1, fibers are transported only by the air flow generated by the front roller 5-1 to prevent the disturbance and consequently the yarn fluctuation.

IPC: G03G15/00
Filed: 1997-05-28
Abstract: PROBLEM TO BE SOLVED: To realize the prevention of paper staining caused by forgetting to change over a paper ream weight setting switch and appropriate control in each driver by setting paper information by a host device. SOLUTION: A selection mark detecting sensor 7 reads the paper information set by the host device, which is expressed by an identification mark. Since the ream weight of the paper 1 is discriminated according to the paper information, fixing oil is supplied by a necessary amount from an oil pump 5 to a Teflon (R) felt 4, and applied on a heat roll 3. The felt 4 is driven by a felt motor 6 to be taken up by a take-up roller 9 from a felt supply roller 8. The motor 6 drives the felt 4 according to the paper information obtained from the sensor 7, so that the felt 4 is taken up by a necessary amount by the roller 9. Since the paper information is set by the host device, an operator need not change over the paper ream weight setting switch.
