Filed: 1998-12-01
Abstract: PROBLEM TO BE SOLVED: To promptly supply water while removing cations contained in the water for washing by deciding the execution period of a reproduction processing in an ion removal means between a final rinsing process and the water supply start of the washing process of the next time. SOLUTION: After dehydration is ended, a microcomputer lights a light emitting diode and performs salt feeding display. Viewing it, a user opens the lid 30 of the ion removal means and feeds the prescribed amount of salt into the ion removal means in order to reproduce ion exchange resin 31. After prescribed time elapses, when the user presses a push button 34c, the salt water is made to flow down among the ion exchange resin 31 and discharged from a salt water discharge port 29c. Then, the ion exchange resin 31 is reproduced and calcium and magnesium are extracted in the salt water inversely. In such a manner, since the ion removal means is used by performing the reproduction processing, the water is promptly supplied while removing the cations contained in the water for washing.

Title: Adhesion strength evaluating method for insulation coating film on insulated wire
Inventor: MATSUURA HIRONORI
IPC: H01B13/00
Filed: 1992-12-22
Abstract: PURPOSE:To allow evaluation of the adhesion strength of an insulation coating film by making two parallel cuts reaching the wire in the insulation coating film at a predetermined interval in the longitudinal direction of the wire and then measuring the peeling strength of the coating film between the cuts. CONSTITUTION:Two parallel cuts (c) reaching an inner wire 10 are made, at first, in the insulation coating film 11 of an insulated wire 1. In this regard, the interval between the cuts is set at 2/3 or less of the wire diameter and at 0.3mm or above. When the interval exceeds 2/3 of the wire diameter, the radius of curvature of the coating film 11 increases too much to allow smooth peeling and when the interval is less than 0.3mm, measuring operation becomes difficult and the coating film 11 breaks easily. A cut (k) is then made at one end part of the cut (c) and the coating film 11 is peeled off the wire 1 with the strength at that time being measured by means of a thermal machine tester, etc. This method allows finer evaluation of the adhesion strength of the coating film 11.

Title: Focus error detector
Inventor: KANO YOSHINORI
IPC: G11B7/09
Filed: 1991-12-25
Abstract: PURPOSE:To prevent the occurrence of comatic aberration by using a branching device consisting of a prism which has a square section, two incident surfaces tilted by each prescribed angle to the optical axis of the signal light, and two parallel projecting surfaces set counter to the incident surfaces. CONSTITUTION:A rhombic prism 10 which is different from the conventional one is used as a branching device. This prism 10 consists of a transparent medium which has a rhombic section, two incident surfaces a-b and a-d having the same tilt angle theta to the optical axis of the signal light B, and two projecting surfaces c-b and c-d set counter to the surfaces a-b and a-d respectively. The signal light B1 is refracted at an incident point O1 of the surface a-b, refracted again at a projecting point Q1 of the surface c-d, and projected to a two-split photodetector 13 at a refraction angle +r1. Meanwhile the signal light B2 is refracted at an incident point O2 of the surface a-b, refracted again at a projecting point Q1 of the surface c-b, and projected to the photodetector 13 at a refraction angle +r2. These light B1 and B2 are refracted to be complementarily focuses on the surface c-b and c-d and therefore the same image forming point P is set on the photodetector 13. Thus the comatic aberration is never produced.

Title: Fixing device
Inventor: TANABE MASATOSHI
IPC: G05D23/00
Filed: 1989-12-28
Abstract: PURPOSE:To prevent a film from deforming locally and a heating body from breaking by providing a control means which controls the driving circuit for the heating body according to temperature difference information obtained by a comparing means and the timer time obtained by a timer means. CONSTITUTION:In the starting of the driving of the heating body 12, the heating body 12 is driven and controlled so as to increase the set temperature of the heating body above a normal set value until temperature difference between the heating body 12 and the member of a film movement driving system decreases below a specific value, namely, until the member of a film movement system rises in temperature above a certain extent. Therefore, the fixing performance of an image in the starting of the driving of the heating body 12 is improved. After the heating body 12 is driven in the steady state, the driving circuit for the heating body is controlled into a non-operation state when the temperature difference between the heating body 12 and the member of the film movement driving system exceeds the specific value. Consequently, even if the movement driving system for the film 9 becomes abnormal for some reason, trouble such as the thermal deformation of the film 9 due to overheating and the heat loss of the heating body is precluded.
