Title: Surface acoustic wave device
Inventor: ISOBE ATSUSHI
IPC: H03H9/145
Filed: 1990-07-04
Abstract: PURPOSE:To realize a surface acoustic wave device with an excellent temperature characteristic by making a rate of a change in a propagation speed of a surface acoustic wave with respect to a temperature substantially equal to a thermal expansion rate of a piezoelectric substrate. CONSTITUTION:The device is provided with a piezoelectric substrate 1 through which a surface acoustic wave is propagated, and metallic films 2, 3 to stimulate, to receive or to reflect the surface acoustic wave on the piezoelectric substrate 1. Then a sum of a rate of a chance in a propagation speed of a surface acoustic wave with respect to a temperature while the metallic films 2, 3 are provided onto the piezoelectric substrate 1 and a thermal expansion rate of the piezoelectric substrate 1 is selected smaller than a sum of a rate of a change in a propagation speed of a surface acoustic wave with respect to a temperature while the metallic films 2, 3 are not provided onto the piezoelectric substrate 1 and a thermal expansion rate of the piezoelectric substrate 1. Thus, the temperature characteristic of the amplitude or phase of a surface acoustic wade while the metallic films 2, 3 for an aluminum electrode or the like are provided is improved.

Title: Toner for developing electrostatic charge image
Inventor: MORI HIROMI
IPC: G03G9/087
Filed: 1990-07-04
Abstract: PURPOSE:To obtain a toner improved in a low temp. fixing property and a low temp. offset property and having a wider non-off set region by providing respectively >= 1 of the peaks at <= 2000 and >= 10000 the molecular weight distributions with a gelpermeation chromatography (GPC) on a THF solubility, and raising the absorption peak temp. of a releasing agent component higher than the absorption peak temp. of a binder resin component. CONSTITUTION:In the toner being obtained with the suspension polymerization of a polymerized polymer system incorporating a releasing agent and a coloring agent in an aqueous medium, the releasing agent in the toner imparts mainly the prevention from a high temp. offset and for a low temp. fixation of the toner, the glass transition temp.; Tg, of the binder resin is a principal factor. The releasing agent crystallizes just before melting and absorbs head and prevents a low temp. fixation. But since the addition of a releasing substance is effective for the prevention of a high temp. offset, it can be not excluded. Here when the toner has a specified peak in the molecular weight distribution with the THF soluble GPC and the coincidence between the absorption peaks of the binding resin and the releasing agent is avoided and the improved toner is obtained.

Title: Electrode feeding control for electric discharge machine
Inventor: KONNO MASANORI
IPC: B23H7/30
Filed: 1984-08-27
Abstract: PURPOSE:To control feeding of electrode thus to shorten the machining time by detecting the machining condition of electrode gap with predetermined time interval and advancing/retracting the electrode by unit movement or stopping while increasing the unit movement upon continuation longer than predetermined time or more than predetermined times. CONSTITUTION:Reaching of continuous advancing time counter CF to CFmax will mean continuation of advancing command longer than predetermined time and if the unit movement DELTAX has not reached to the maximum DELTAXmax, the movement DELTAX is increased by setting value DELTAX. Similarly, in case of retraction, the unit movement DELTAX is increased by setting value DELTAX. In such a manner, electrode feeding is controlled with small unit movement in case of normal machining condition of electrode gap while with large unit movement in case of abnormal condition thus to prevent lengthening of machining time.

Inventor: INUTA MASANORI
IPC: F16H61/10
Filed: 1984-08-25
Abstract: PURPOSE:To correct an abnormal value and prevetn a time lag and a decrease in acceleration during starting by substituting the abnormal pulse value of an automobile speed, rotating speed of a driving source, etc., with the number of pulses obtained by adding or subtracting the number of pulses which are counted previously. CONSTITUTION:The device consists of a sensor 5 which outputs pulses corresponding to the rotating speed of a drive transmission device, a counter 7, a comparing means which calculates the difference in the number of pulses, a judging means which judges an abnormal value, an adding and subtracting means which adds or subtracts a maximum variation range, and a control signal output means. The control means compares the number P2 of pulses which are counted at constant intervals of time with the number P1 of pulses which are counted previously. The when the difference ¦Pc¦ between the both is larger than the maximum variation range DELTAP of the preset number of pulses which may be generated during a steady run, the number P2 of pulses is judged as an abnormal value and the maximum variation range DELTAP is added to or subtracted from the number P1 of pulses which are counted previously. Then, the number P2 of pulses is substituted with the calculated number P3 of pulses and various control signals such as a speed display signal corresponding to the number P3 of pulses are outputted.

Title: Kana character making method in roman character type keyboard
Inventor: SUWA KUNIO
IPC: G06F3/02
Filed: 1996-06-03
Abstract: PROBLEM TO BE SOLVED: To make a Roman character type keyboard usable with consciousness to the Japanese syllabary and with no consciousness to the alphabet by marking HIRAGANA (cursive form of Japanese syllabary) or KATAKANA (square form of Japanese syllabary) just after performing the marking in KATAKANA characters or in their combinations. SOLUTION: In a Roman character mode of a word processor, 'A', 'I', 'U', 'E', 'O' and 'KA' are inputted in KATAKANA or HIRAGANA by means of their KATAKANA keys respectively. Then, 'KI' is inputted in KATAKANA or HIRAGANA by the keys 'KA' and 'I' of KATAKANA. Furthermore, 'KU', 'KE' and 'KO' are inputted in KATAKANA or HIRAGANA by the keys of 'KA' and 'U', 'KA' and 'E', and 'KA' and 'O' of KATAKANA respectively. Thus, it's not required for an operator to fast process in his brain the knowledge of both alphabet and Roman characters which are conventionally needed for input of the Roman characters.
