Title: Production of silica gel
Inventor: MIKI TAKESHI
IPC: C01B33/154
Filed: 1997-11-19
Abstract: PROBLEM TO BE SOLVED: To remove ions or easily ionized foreign matters without deteriorating hygroscopic ability and moisture releasing ability and to reduce the quantity of a gas generated from a silica gel by crushing a silica gel obtained by neutralizing sodium silicate with sulfuric acid and after that, washing with pure water. SOLUTION: The silica gel is obtained by neutralizing sodium silicate with sulfuric acid. The silica gel is crushed and washed with the pure water having >=1 MΩ.cm an specific resistance to remove sodium sulfate generated in the neutralization. A desiccant pack, in which the silica gel is sealed, is mounted in a magnetic disc device. As a result, the effect of the ions such as Cl, NO3 , SO4 <-2> or the easily ionized foreign matters stuck to the silica gel in the midway of the silica gel production process 1 is prevented, the quantity of the gas generated from the silica gel is reduced and the reliability of the magnetic disc device is improved.

Title: Temperature expansion valve
Inventor: TANAKA SO
IPC: G05D23/12
Filed: 1988-12-19
Abstract: PURPOSE:To make it possible to send refrigerant to an evaporator even when its degree of superheat is small by giving an additional power to a valve disk pushing power based on a superheat signal and an amount of diaphragm deflection when a differential pressure between the upper stream side and the lower stream side of refrigerant is larger than a reference differential pressure which sets a superheat degree at a rest. CONSTITUTION:When a liquid flows at a pressure higher than a certain differential pressure against the power of a power element which affects the opening/ closing of a valve, the size of a valve port 10 is made sufficiently larger in terms of an effective size of a diaphragm 2 of a power element so that the valve may be opened, and a valve disk is designed to be a cone-shaped valve so that the power produced by the flow of a fluid may be taken out effectively, then the apex angle of the cone is determined. Therefore, when the vaporization temperature or the vaporization pressure is lower as a result of deviation from the superheat characteristics a standard state valve lift (valve opening area), the valve can be opened even with a superheat degree signal which has not reached the degree of statical superheat and refrigerant is supplied to an evaporator.

Title: Production of shucked shellfishes
Inventor: ISHIHARA TOSHIKAZU
IPC: A23L17/40
Filed: 1998-11-10
Abstract: PROBLEM TO BE SOLVED: To provide a method for producing shucked shellfishes convenient for handling by which drips are not caused at the time of thawing and cooking while leaving tastiness of the shellfishes and keeping quality is retained by half-boiling the shucked shellfishes and quick freezing the half-boiled shucked shellfishes in relation to a method for producing the shucked shellfishes of bivalves such as a short-necked clam or a hard clam. SOLUTION: Shellfishes after testing the freshness state, shape, etc., are preserved in seawater at about 15 deg.C temperature for 8-12 h to carry out sand discharge and the seawater is replaced several times at an interval of about 2 h to remove sand. Impurities such as flesh out of shape, shells and hair are removed from the shellfishes after carrying out the sand removal one by one to carry out the hand shucking while conducting the grading. The shells and shellfishes are washed in flowing water while removing foreign materials such as sand or shells and then heated at >=95 deg.C for about 20 s to perform blanching. The blanched shucked shells and shellfishes are subsequently cooled with ice water, quick frozen at <=-35 deg.C and clear water is cooled to carry out the glazing. The glazed shucked shells and shellfishes are then refrozen at <=-35 deg.C.

Title: El element drive derive
Inventor: KAZAMA HIROYUKI
IPC: H05B44/00
Filed: 1998-11-10
Abstract: PROBLEM TO BE SOLVED: To provide an EL element drive device capable of embodying the longer life of EL elements by most adequately compensating the deterioration in the luminance of the EL elements. SOLUTION: Charge current and discharge current are supplied by respective transistors(TRs) from both ends of the EL element 1 having an equivalent capacitor Cel at the current value controlled by a current control section 12 while the timing is adequately controlled by a switch control section 11. As a result, the drive current Iel and drive voltage Vel of the EL element 1 change periodically and the EL element 1 may be driven. The current (i) subtracting the feedback current ic flowing to a resistor R connected to the mid-point of a voltage dividing circuit connected with two resistors (r) in series with respect to reference current I0 flows to the TR Q11. The current of the specified coefficient times thereof is the drive current described above.  The increase of the drive voltage Vel is made gentle and the more than needed increase in the luminance of the EL element 1 is averted by applying such feedback even if the equivalent capacitor Cel is reduced by the increase in the service time on the EL element 1. The longer life may be eventually achieved.

Title: Cleaning device
Inventor: MOTOMURA MINORU
IPC: G03G21/10
Filed: 1995-12-08
Abstract: PROBLEM TO BE SOLVED: To execute a durable cleaning action without damaging photoreceptor by executing it by pressing a pressing plate to the circumferential surface of a drum without using a cleaning blade. SOLUTION: The thin pressing plate 3 facing the photoreceptor drum 2 side and having an aperture part on the circumferential surface side of the drum 2 is fitted to a frame 1a. The plate 3 is constituted so that the whole area of the contact surface thereof acts as the surface to be cleaned of the drum 2 while being bent along the circumferential surface of the drum 2. The back part of the plate 3 is provided with a pressing auxiliary member 4 such as a spring for pressing the plate 3 to the drum 2 side. Since the aperture part is formed on the plate 3 and the plate 3 is pressed to the drum 2, residual toner on the circumferential surface of the drum 2 is removed by the edge of the aperture part and the drum 2 is cleaned. Besides, when the auxiliary member 4 is arranged at the upper part in the figure, that means, on the downstream side in the rotating direction of the drum, it is effective by interlocking with the cleaning action extending over the downstream side from an upstream side because more pressure is applied on the downstream side.
