Title: Printing apparatus
Inventor: WATANABE KATSUHIRO
IPC: B41J11/42
Filed: 1997-04-08
Abstract: PROBLEM TO BE SOLVED: To enable printing to many kinds of print media each having a print face of a predetermined radius of curvature, by detecting the radius of curvature of the print face of the print medium and print the medium while controlling a rotational angular velocity of the print medium by a medium-rotating means on the basis of the detected result. SOLUTION: When a belt-driving roller 30 rotates by a predetermined amount, a print medium 26 on a transfer belt 29 drops in between a pair of inclined faces 32a and 32b of a measurement block 32 and supported by the measurement block 32. At this time, a touch sensor 33 moves downward on a bisector of an angle defined by the pair of inclined faces 32a, 32b. At a position when the touch sensor 33 comes in touch with the medium 26, the touch sensor 33 transmits a heightwise position of itself to a control part. The control part obtains a distance to an upper end of the medium 26 from a preliminarily set intersection of the pair of inclined faces 32a, 32b, and calculates a radius of the print medium 26 from the distance. A rotational angular velocity of the medium 26 is controlled on the basis of the calculated result when printing is conducted.

Title: Method and apparatus for controlling operation of air conditioner
Inventor: IWATA HIROSHI
IPC: F24F11/00
Filed: 1981-06-12
Abstract: PURPOSE:To achieve an effective power-saving operation of an air conditioner by operating a compressor so as to always ensure a higher enrgy efficiency EER while maximizing the efficiency than would when it runs at the full operation with a capacity control rate of alpha=0, without capacity control. CONSTITUTION:The energy efficiency EER reaches it maximum under the temperature ta of an outside air as the capacity control rate alpha of a compressor goes to alphaMAX. To effect the capacity control of an air compressor according to a load, a compressor is operated at alphaMAX with a capacity control in stead of at alpha and the whole of the air conditioner is turned on or off by an excessive part of the heaing capacity, except for when the capacity control rate is below MAX. This enables the capacity control of the air conditioner at a larger value of EER than would when the air conditioner is on-off controlled without the capacity control of the compressor thereby increasing the power-saving effect.

Abstract: PURPOSE:To set the KANA (Japanese syllabary) character, which is the converting object, to the narrow scope when equivalent KANJI (Chinese character) are not obtained by retrieving the stem of the word by starting the candidate Chinese character retrieving mechanism with the KANA character changed by the KANA KANJI number changing means as the converting object. CONSTITUTION:When a KANJI-mixed sentence is KANA-inputted by the operation of a keyboard 11, it is successively stored into an input buffer 19, displayed on a displaying part 12 and the number of the input characters is stored in a RAM 21 for the work. When a converting/next candidate key fa is operated, maximum five characters are read from the head of the KANA character string stored in the input buffer 19, and the converting object character data are decreased. Based upon the character string, a KANJI converting dictionary 20 is indexed, the character of the stem of the work exists, and then, out of the input character string inverted and displayed at the displaying part 12, to the object character of the stem of the word, the underline is given. When the character of the stem of the word is not detected, next, the stem of the word is retrieved again by the input character to decrease one character. When it is detected that the converting object character number is '0', the character is written in a document memory 17 as the fact that the equivalent Chinese character is not found at the inputted KANA character.

Filed: 1978-07-24
Abstract: PURPOSE:To realize an A-class push-pull amplifier which features a high efficiency and low distortion rate by varying the bias voltage of the output-step transistor in accordance with the output. CONSTITUTION:The difference of the input potential and the output potential is detected by operational amplifier A1 between output-step transistors Tr7 and Tr8 and then applied to the base of transistor Tr2 forming the bias voltage circuits of Tr7 and Tr8. No cut-off state is given to Tr2 since the emitter is connected to the constant current source, and at the same time Tr2 is so set as not to be saturated completely by diode D1. Thus transistors Tr7 and Tr8 always operate only at the driving region. So is for output-step transistors Tr9 and Tr10 of the other side which constitute a push-pull amplifier.

Title: M-phase psk modulator
Inventor: YOKOGAWA KAZUMASA
IPC: H04L27/20
Filed: 1995-04-17
Abstract: PURPOSE: To avoid a spectrum from being spread by adding an insertion signal to a base band information signal so as to reduce a fluctuation in an input amplitude level to a nonlinear amplifier when a phase locus of an m-phase PSK passes through an origin. CONSTITUTION: An insertion signal generator 6 receives information denoting information signal phase transition on a phase plane from a signal point arrangement device 2 and generates selectively an insertion signal of a complex base band in the case of phase transition of ±3π/4. In this case, the insertion signal is generated so that a signal locus of a synthesis signal between the base band information signal and the insertion signal on the phase plane does not pass through in the vicinity of the origin. The insertion signal delayed by a waveform shape filters 3a, 3b is caused by a delay device 8 and added to an in-phase and an orthogonal component of the base band information signal by an adder 9. The signal after synthesis is up-converted by an orthogonal modulator 4 and given to a nonlinear amplifier 5 having a dead band.  Thus, only th generator 6 has only to be added to a conventional system.
