Title: Method for sterilizing anion surface active agent aqueous solution
Inventor: ITO YOSHIKAZU
IPC: A61L2/08
Filed: 1989-12-19
Abstract: PURPOSE:To sterilize an anion surface active agent aqueous solution without destroying the structure of the surface active agent by irradiating the anion surface active agent aqueous solution generally used for cosmetics or a detergent raw material with the sun light or ultraviolet rays. CONSTITUTION:An anion surface active agent aqueous solution indicated by the formula (I) is put in a vinyl bag and sealed, and it is put in an open drum and left under the outdoor sun light with a cover opened. For ultraviolet rays (320-400nm), the aqueous solution is put in a storage tank, the ultraviolet rays are irradiated through a glass window fitted to the tank. For ultraviolet rays (280-320nm), the window is made of quartz glass, and irradiation is likewise performed. The sun light or the ultraviolet rays act sterilely and sterilize various Gram negative bacterium easily proliferated in the anion surface active agent aqueous solution. For the irradiation period of each light, the effect appears in about 10 days when the 25wt.% aqueous solution is put in a 200(l)-container and the sun light is irradiated with no cover, and in about 10hr when the 25wt.% aqueous solution 50ml is put in a glass container and ultraviolet rays are irradiated, for example.

Title: Ink jet recording device
Inventor: YANO KENTARO
IPC: B41J2/175
Filed: 1989-12-19
Abstract: PURPOSE:To improve the response characteristics of a rotor and to enhance recording quality by providing a means detecting ink volume remaining in a carriage and a means varying the output torque of a motor according to the detected result. CONSTITUTION:The serial ink jet recording device is so designed that an interchangeable head cartridge 31 that integrally forms a head 5 and an ink tank is mounted on a carriage 6 moving along a platen and the head 5 scans a sheet and records with a carriage motor 23 as a driving source. In this recording device, ink remaining in the head cartridge 31 is detected and conditions for driving the carriage motor 23 are changed according to the ink residual. Consequently, vibrational noise arising in a motor driving system or motor itself, which results from load fluctuation due to a change in the ink residual, and the inversion noise of the carriage 6 arising when the motor is accelerated or decelerated can be prevented. since ink quantity in the head cartridge can be made greater, a noisefree device requiring low running costs can be accomplished.

Abstract: PURPOSE:To improve display characteristics by allowing a diamine component to constitute a polyimide and to possess a chemical structure in the mutual joint between the planary molecules by bent atoms, and allowing the surface energy of a polyimide coating film to have 35dyne/cm or less. CONSTITUTION:Two glass plates each of which has a thickness of 1.1mm and consists of an ITO film having a thickness of 1000Angstrom  are prepared, and a 3.0wt.% solution of polyamide acid represented by the formula in N-methyl pyrolidone/n-butyl cellosolve =5/1 is applied to form a film on each glass plate through spin coating, and heating-baking-processed at 250 deg.C for about 1 hour. Then, the one-direction rubbing processing by a nylon planted cloth is carried out. After the alumina beads having an average particle diameter of about 1.5mum are scattered on one substrate, two glass substrates are superposed so that each rubbing processing axis is parallel each other and in the same processing direction, and a cell is formed. A ferroelectric smectic liquid crystal is poured into the cell under the isotropic phase under vacuum pressure, and gradually cooled from the isotropic phase to 30 deg.C at a slow speed of 0.5 deg.C/h.

Abstract: PURPOSE:To provide a radio wave altimeter with excellent obstacle-resisting performance and very low altitude performance and with high precision from low to high velocity. CONSTITUTION:Signals generated from an oscillator 1 are subjected to two-phase random modulation 4 using a random code generator 20 at an oscillation frequency fc and transmitted to a space and the reflected waves of the signals are received 5, 6, 7 and intermingled with signals from the oscillator 1 and the output signals are distributed using a distributor 8.

Title: Magnetic reproducing device, magnetic recording and reproducing device, and tracking control method
Inventor: SAKURAI TETSUO
IPC: G11B15/473
Filed: 1993-12-27
Abstract: PURPOSE:To perform stable tracking control irrespective of the level of a playback tracking control signal at the time of fast reproduction, etc. CONSTITUTION:When a head traces tracks on a tape at first reproduction time as shown by (A) in the figure, an ATF pilot signal is reproduced at the hatched parts, so its envelope detection waveform is as shown by (B). A position of this waveform which is shown by alpha is detected and the transmit phase of the tape is so controlled that the phase difference between the rise of a phase control signal (G) showing the position and the 0 deg. position of switching pulse (A) reaches a certain fixed value T3 shown by (D). Consequently, the trace phase of the head corresponding to the track pattern is controlled into certain relation. In this control, a ratio beta/alpha from the peak of the detection waveform is used to detect the position shown by alpha, so precise tracking control can stably be performed irrespective of the reproducing level fo said detection waveform, i.e., the level of the ATF pilot signal.

Abstract: PURPOSE:To suppress the sudden change of differential pressure or filter speed and to enhance filter yield by forming a precoating layer wherein fine and coarse particle precoating layers of a filtration auxiliary agent are doubly superposed one upon another on the outer surface of the filter material of a filter. CONSTITUTION:When coarse and finer particle precoating layers are formed to the filter material 3 of a precoating filter 2, the precoating auxiliary agent tank 9 connected to the filter 2 through a classifier 7 is connected to a filtration auxiliary agent tank 30 and the tank 9 is connected to the filter 2 by a pump 25. In a process wherein a coarse and fine particle auxiliary agent 34 is mixed with a liquid to be filtered and to circulate to the filter 2, the auxiliary agent 34 is separated into a coarse particle agent and a fine particle agent and only the fine particle auxiliary agent is formed to the filter material as a precoating layer at first and, subsequently, the coarse particle auxiliary agent is applied to the fine particle precoating layer. As a result, differential pressure and the sudden change of filter speed are suppressed to make it possible to enhance filter yield by 50% or more and a filtrate can be increased by about twice.

Title: Pachinko machine
Inventor: WATANABE KANEHISA
IPC: A63F7/02
Filed: 1994-12-08
Abstract: PURPOSE: To make game playing flexible to prevent the player from loosing interest by determining, if a special playing state arises, whether or not special patterns are selected as being stopped at special pattern display portions, with different probabilities in high- and low-probability states. CONSTITUTION: When a game ball scores, with a normal motor-driven generator 6 being open or closed, a predetermined number of prize balls is released, special patterns start to fluctuate, and the fluctuation is stopped either a predetermined time thereafter or under the control of the player. If all the patterns stopped are the same at pattern display portions L1, L2, L3, a special playing state is initiated in which the door 7 of a big scoring machine opens for a predetermined time or until a predetermined number of balls has scored, and then, if a ball enters a consecutive scoring slot inside the big scoring machine, the door 7 of the big scoring machine opens only for a predetermined number of times after being closed.  Thus, when the special playing state arises, whether or not special patterns are to be selected can be determined at a specific probability and so the enjoyability of the game can be enhanced.
