Title: Production of alpha-ketol
Inventor: ISHII KENJI
IPC: C07C45/00
Filed: 1982-05-21
Abstract: PURPOSE:An alpha-hydroxycarboxylic acid with the optically active center on the hydroxyl is made to react with an alkyllithium to give an alpha-ketol maintaining optically active hydroxyl, which is used as an attractant to females of Xylotrechus pyrrohdens Bates. CONSTITUTION:For example, L-(+)-lactic acid is dissolved in anhydrous tetrahydrofuran and n-amyl lithium is added dropwise thereto at 0 deg.C within 1hr by 2/3 of the total amount, then the rest of 1/3 is added at room temperature within 3hr and they are stirred one overnight. Saturated aqueous ammonium chloride is added to the reaction mixture at 0 deg.C. After sodium chloride is added, the mixture is extracted with ether 3 times and the extract is washed with saturated sodium chloride aqueous solution, until the extract becomes neutral, then dried over magnesium sulfate. The extract is concentrated and the resultant oil substance is purified by means of silica-gel column chromatography to give (2S)-hydroxy-3-octanone.

Title: Cmos transistor oscillating circuit provided with agc circuit
Inventor: HASHIMOTO MASAMI
IPC: H03G3/20
Filed: 1982-05-21
Abstract: PURPOSE:To save useless energy consumption, by detecting an oscillating amplitude representing an index of an oscillating state to control the gain of an amplifier circuit. CONSTITUTION:A C-MOS transistor circuit 20 amplifies a signal inputted from a gate and gives an output to a drain. When the output amplitude of the circuit 20 is changed, a DC voltage formed at an oscillating amplitude detecting circuit 22 is changed and a bias voltage supplied from a bias circuit 21 to the circuit 20 is changed accordingly. The gain of the circuit 20 is controlled with this bias voltage change, allowing to keep the output amplitude of the circuit 20 constant at all times. Since this output amplitude is kept constant, the energy more than required in the oscillation circuit is not consumed and the stability of operation of the circuit of the next stage is attained.

Abstract: PURPOSE:To prevent the deterioration of a liquid crystal as well as printing and flickering by connecting the TFT of an n channel and the TFT of a p channel in parallel and providing positive and negative polarities to a gate pulse to make pulse electrically symmetrical. CONSTITUTION:The n channel TFT 7 and the p channel TFT 8 are connected as one set in parallel between the respective lines of the gate, source and drain for one display picture element electrode. The threshold of the n channel TFT 7 is assumed to be positive and the threshold of the p channel TFT 8 to be negative and the absolute values thereof are assumed to be larger than the voltage for sufficiently lighting the liquid crystal at this time. The TFT 7 of the n channel turns on and the signal from the source line enters the drain electrode in the case of the positive gate pulse if the gate pulse having the positive and negative polarities is impressed to the TFT element of such constitution. The TFT 8 of the p channel having the sufficient negative threshold is, however, held turned off and, therefore, no influence is exerted at all on driving. The deterioration in the liquid crystal as well as the printing and flickering are obviated in this way.

Abstract: PURPOSE:To perform accurate judgment by judging a defect when two or more detected signals are obtained from an inner surface part or an outer surface part. CONSTITUTION:When there is a defect in an outer surface part, a pre-detection signal is differentiated in a differential device 17. Then two differentiated signals are generated in a signal level changing part for the defect and a signal falling part for outer surface edge. The signals are compared with a (-) high reference value HF(-)H and a (-) low reference value HF(-)L in comparators 31 and 32, respectively. When the differentiated signal exceeds the (-) low reference value HF(-)L, the two compared detected signals are continuously taken out of the comparator 32. A comparing area signal T2 is generated in a timing signal generating circuit 22 at the comparison timing of the differential signal from the outer surface part and each reference value. A switch 34 is controlled to an ON state. The two comparison detected signals are inputted into a counter judging circuit 36. As a result, two pulses of the comparison detected signals are counted at the time of one scan of the light beam in the circuit 36. A judged signal for indicating the presence of the defect in the outer surface part is outputted. Thus the quality can be judged accurately.
