Title: Reset device
Inventor: HAMAMATSU SHIGERU
IPC: G06F1/24
Filed: 1990-09-07
Abstract: PURPOSE:To evade the reset state of the device during its operation by driving a switch with a relay driving circuit to switch a battery to a feeding circuit when the voltage exceeds a level where a power failure is decided and then resetting a microcomputer. CONSTITUTION:A feeding circuit 1 outputs the voltage to actuate a microcomputer 5 when a power failure is recovered and a relay driving circuit 8 outputs a signal to drive a relay circuit 7. Thus a switch 6 is changed toward the circuit 1 and therefore the power voltage is supplied to the microcomputer 5 from the circuit 1. Meanwhile a reset pulse of the prescribed width is outputted to the terminal RST of the microcomputer 5 when a reset circuit 9 detects the recovery of the power failure. Thus no reset state occurs in a power saving mode and in a driving state at a power failure.

Title: Speech reproducing method
Inventor: MISAKI MASAYUKI
IPC: G10L21/04
Filed: 1991-09-18
Abstract: PURPOSE:To obtain a reproduced speech which can be heard as a natural speech even when its reproducing speed is varied and also reducible in process distortion in a voice section by finding the ratio of speech section length of specific block length and overall block length, comparing the value with a desired time compression ratio, and selecting a compressing method according to the result. CONSTITUTION:The ratio Rv of the total time length of the speech section in one block of an input signal and the time length of the whole block is found and compared with the compression ratio Rc of the time compression of the input signal. When Rc>=kRv (k: constant), only voiceless sections are compressed. When Rc<kRc, on the other hand, independent compression ratios are set for the voiceless sections and speech sections and the time compression is performed. Thus, an elongation ratio is varied for the voiceless sections and speech section according to the value Rv, so the speech which is close to the natural speech can be reproduced.

Title: Electronic photo-stand
Inventor: OMURA AKIRA
IPC: G09F9/00
Filed: 1999-08-25
Abstract: PROBLEM TO BE SOLVED: To prevent occurrence of inconvenience on an information image even when a display portion of an electronic photo-stand is rotated according to a composition of an ornamental image, by storing the ornamental image and the information image including character information for simultaneously displaying, and rotating the information image independently of the ornamental image to be displayed on a display portion. SOLUTION: This electronic photo-stand comprises a frame 1 and a pedestal 2. A memory stores an ornamental image and an information image including character information. A display portion can simultaneously display the ornamental image and the information image. A CPU controls so as to rotate the information image independently of the ornamental image to be displayed on the display portion. The display portion of the frame 1 matches to a longitudinal/ transverse ratio of the ornamental image. When the ornamental image is intended to be rotated by, for example, 90 deg., the displayed image is not rotated but the frame 1 itself is rotated because the longitudinal/transverse ratio is different. Thus, the display of the information image is controlled responsive to the attitude of the frame 1.

Title: Sheet feeder
Inventor: HIRANO HIROFUMI
IPC: B41J13/02
Filed: 1985-10-28
Abstract: PURPOSE:To make pressure-contact force of a sheet keeper adjustable without using a special member, by rotation a sheet guide having a regular interval with a circumferential surface of a sheet feed roller, while pressing the sheet keeper with its end part, and making the pressure-contact force to the roller so as to be weakened. CONSTITUTION:When a recording sheet's edge is turned up or it is conveyed with a pin tractor feed system, if a releasing lever is operated and a sheet guide member 5 is rotated in a rotation downstream direction of a feed roller 1, an end part 5d of this rotated guide member 5 comes into contact with a sheet keeper 10, pressing this keeper in a (b) direction. In consequence, pressure- contact force between the sheet keeper 10 and the roller 1 is weakened to the extend of 0-5g/cm<2> or o, and a pinch roller 8 runs on a releasing part 7c where a releasing cylindrical part 8b rotates, whereby its pressure-contact with the roller 1 is released. Therefore, the recording sheet is feedable along a circumferential surface of the roller 1 without any resistance, and truing-up the sheet or the like is performable in good operating conditions. Here the pressure-contact force between the sheet keeper 10 and the roller 1 is variable at will adjustment for turning value of the sheet guide member 5.
