Title: Filling back method for surrounding of structure
Inventor: KOTANI KATSUMI
IPC: E02D31/02
Filed: 1991-11-08
Abstract: PURPOSE:To obtain high water-stopping effect as well as high waterproofing effect for a structure by isolating the structure from the ground water in the surrounding ground by a filling back material. CONSTITUTION:After a semi-underground structure 2 is constructed, an aperture D is formed between the outer wall of the structure 2 and the surrounding ground E. A filling back material 3 formed by mixing soil with a water-swelling fibre in an adequate proportion is charged into the aperture D to fill up the aperture D, where groundwater permeates into the filling back material 3. The water-swelling fibres in the filling back material 3 are expanded and gelled to form a water shield layer in which the soil particles are blocked, and a consolidating effect can also be obtained by the volume expansion of the fibres.

IPC: H01S3/097
Filed: 1992-11-05
Abstract: PURPOSE:To provide a gas laser apparatus in which a large amount of clean medium gas is not required to keep the inside of a window in a clean condition and problems such as an increase in cavity length or a leakage from a piping connecting part do not occur and a deterioration of an aperture can be prevented. CONSTITUTION:A dust filter case 9 is connected to a chamber 1 for holding main electrodes 3 and 4, and a clean medium gas filtered with a filter 13 is introduced into a secondary chamber 14 through a gas inlet passage 11 formed in the sidewall of the chamber 1.

Title: Information recorder/reproducer
Inventor: UEKI YASUHIRO
IPC: H02P6/08
Filed: 1991-11-08
Abstract: PURPOSE:To make it possible to operate an information recorder/reproducer even with a power supply voltage lower than 5V by controlling the voltage of a motor driving circuit according to the output from a power supply voltage monitoring means. CONSTITUTION:A microprocessor 11 subjects a power supply voltage VCC to A/D conversion in order to measure a voltage value. Assuming the rotational angle of motor at (n) times from the start of rotation is thetan, inertia of motor is J, and torque of motor is T, one cycle time tn at the time of starting can be represented by a formula. Torque T decreases in proportion to decrease of the power supply voltage VCC. Time tn for power supply voltage VCC of 5V is written, as a standard value, into a ROM of the microprocessor and the torque T is corrected according to the detected power supply voltage thus performing control using the calculated time tn. According to the invention, information recorder/reproducer can be operated even when the power supply voltage drops below 5V.
