Title: Ultrasonic motor
Inventor: MURATA YOSHITAKA
IPC: H02N2/00
Filed: 1998-10-05
Abstract: PROBLEM TO BE SOLVED: To provide an ultrasonic motor which eliminates the need for pressurization and for which the structure of a stator is simple. SOLUTION: A ring-shaped piezoelectric element 7 is fixed to the free end of an outside tube part 3 of the thin-wall circular tube structure of a stator 1. A rotor 9 is arranged in a noncontacting manner by keeping a prescribed interval so as to surround the piezoelectric element 7. The rotor 9 is fixed to a shaft 8, which is held freely rotatably by a bearing 5 and a bearing 6, which are fixed to a stator base part 2. When a voltage is applied to the piezoelectric element 7, the piezoelectric element 7 is deformed elastically, and a plurality of point contacts are given with respect to the rotor 9. When the position to which the voltage is applied is made to deviate, positions of the point contacts are moved in the circumferential direction.  When this operation is repeated, rotational difference which is relative to the rotor 9 is obtained with respect to the stator 1, due to the difference between the outer circumferential length of the piezoelectric element 7 and the inner circumferential length of the rotor 9, and this rotational difference becomes the rotation of the rotor 9.

Title: Production of alpha-type nonmetallic phthalocyanine
Inventor: TSUKAHARA HIROKAZU
IPC: C09B67/16
Filed: 1992-10-21
Abstract: PURPOSE:To provide a method for producing in high efficiency and yield an alpha-type nonmetallic phthalocyanine, an intermediate essential for producing a nonmetallic phthalocyanine (e.g. of X-type), an organic pigment having marked photoelectric effect in e.g. electrophotographic techniques. CONSTITUTION:A crude nonmetallic phthalocyanine is added to hydrous sulfuric acid containing substantial amount of water to produce a suspension of nonmetallic phthalocyanine sulfate; the suspension is then directly added to a large quantity of water and the resultant precipitate is separated by e.g. filtration, thus obtaining the objective alpha-type nonmetallic phthalocyanine. With this method, the aimed alpha-type nonmetallic phthalocyanine can be obtained from a crude nonmetallic phthalocyanine at a yield of >=97 % in a short time. The alpha-type nonmetallic phthalocyanine thus obtained gives a highly photosensitive nonmetallic phthalocyanine (e.g. of X-type) by mechanically grinding treatment.

Title: Operational amplifier and digital signal transmission circuit
Inventor: KAWAHARA HIROYOSHI
IPC: H03F1/26
Filed: 1995-10-31
Abstract: PROBLEM TO BE SOLVED: To provide a digital signal transmission circuit suitable for an integrated circuit by removing a noise superimposed on an input signal while using an operational amplifier in the configuration of mixing current feedback type and voltage feedback type operational amplifiers. SOLUTION: When the potential of a non-inverted input terminal (+) is changed from low to high, that potential change is transmitted through a 1st input buffer to the base electrode of a PNP transistor Q2 consisting of differential paired transistors. With the increase of a potential at an output terminal, the potential at the base electrode of a PNP transistor Q3 is transmitted through a 2nd input buffer to the base electrode of the differential transistor Q3 until it gets equal with the base potential of the PNP transistor Q2. In the operational amplifier with such configuration, by providing a through rate, even when a high frequency is inputted to the non-inverted input terminal (+), the noise is removed and the digital signal transmission circuit suitable for the integrated circuit can be obtained.

Title: Mechanical translating device
Inventor: FUKUMOCHI YOUJI
IPC: G06F17/27
Filed: 1986-11-28
Abstract: PURPOSE:To process an input sentence including the quotation marks by means of the same grammar rule as an input sentence including no quotation mark, by storing the positions of quotation marks and producing a sentence where the quotation marks are once deleted. CONSTITUTION:The position of each word is indicated in an input sentence and presence or absence of the quotation marks is checked. If the quotation marks are included in the sentence, a fact that the mark shows an opening double-fort quotation mark (') is stored together with the position of the word having the mark. Then a closing quotation mark (') is searched and stored together with the position of the word having this mark. In case the input sentence includes no quotation mark excluding the searched ones, the quotation marks of the stored position are erased out of a buffer for input sentences. As a result, the subsequent dictionary consulting and morpheme analyzing processes are equal to those applied to an input sentence including no quotation mark. The translation processing is carried out by a CPU 1 based on a program stored in a main memory 2.
