Title: Diagnostic method of partial discharge or gas-insulated apparatus
Inventor: IWAASA SHUZO
IPC: G01R31/12
Filed: 1990-03-19
Abstract: PURPOSE:To make diagnosis as to whether a partial discharge is caused by a conductive extraneous substance or by a crack in a spacer, by providing a gas-insulated apparatus with an incorporated type discharge detector and by detecting a frequency spectrum. CONSTITUTION:An incorporated type partial discharge detector 50 is provided in a grounding tank 20, as a device for diagnosing abnormality inside an apparatus. A signal detected by the incorporated type partial discharge detector 50 is taken in a spectrum analyzer 60 and subjected to a frequency analysis. As to the state of existence of a conductive extraneous substance, a conductive extraneous substance 80 sticking on the surface of a spacer, a conductive extraneous substance 90 fixed on a high-tension conductor, a conductive extraneous substance 100 fixed on the grounding tank and a free conductive extraneous substance 110 can be cited. Although the pattern of a spectrum varies in accordance with these states of the extraneous substances, the relations of HA <= HB and WA <= WB are always maintained in comparison of the spectrum with a frequency 600 MHz taken as a boundary, and therefore a partial discharge can be diagnosed as caused by the extraneous substances. In these relations, the maximum values of spectrum envelopes in the area of the frequency lower than 600 MHz and in the area of the frequency equal to or higher than 600 MHz are denoted by HA and HB and the widths thereof by WA and WB, respectively.

Title: Production of alcohol
Inventor: NISHIGAKI FUTOSHI
IPC: B01J23/80
Filed: 1996-02-27
Abstract: PROBLEM TO BE SOLVED: To produce an alcohol having high quality and purity from a fatty acid ester by a catalytic reduction reaction effective for suppressing the by- production of hydrocarbons, etc., and the deterioration of catalytic activity compared with conventional process. SOLUTION: A fatty acid ester originated from palm oil, etc., is catalytically reduced in the presence of a hydrogenation catalyst such as Cu-Cr. In this reaction, a fatty acid originated from palm oil, etc., is added to the fatty acid ester used as the raw material in an amount of 0.1-30wt.% (preferably 0.1-5wt.%) based on the raw material mixture (mixture of the fatty acid ester and the fatty acid). The hydrogen and the raw material mixture are continuously supplied to the reaction system to keep the molar ratio of hydrogen to the acyl group of the raw material mixture (hydrogen molecule:acyl group) to (5-500):1.

Title: Printing density control device in thermal printer
Inventor: YONEDA SHIGEO
IPC: H04N1/40
Filed: 1981-05-01
Abstract: PURPOSE: To obtain the device in the title wherein the current conducting time of the printing head is controlled in response to the variation in power source voltage, energy which is imparted to a printing head is made to be approximately constant, and the equal printing density can be obtained regardless of the output voltage of the power source used.  
     CONSTITUTION: The output signal frequency is changed by a V-f converter (voltage to frequency converter) 1 in response to an applied voltage V s  which is applied to the printing head from a power source line 2. The power source voltage for printing is applied to the printing head until the counted value of the output signal frequency of the V-f converter 1 reaches the predetermined count value. The time T 01 =t 1 -t 0  from the count starting of a counter 3 to count up is inversely proportional to the oscillating frequency (f) of the V-f converter 1. The lower the applied voltage V s  becomes, and the lower the oscillating frequency  becomes, the longer the current conducting time T s  of the printing head becomes.

Abstract: PURPOSE:To obtain a telephone system capable of completing dial transmission at a prescribed time. CONSTITUTION:A dial number and an arbitrary time TIME1 are set by inputting to the key of a keyboard 5. The dial number and the time TIME1 are stored in a RAM 2. A dial system is judged by the dial system flag of a CPU 1.
