Title: Operational control method of continuous washing machine
Inventor: MAEDA AKIRA
IPC: D06F31/00
Filed: 1991-05-31
Abstract: PURPOSE:To decrease the loss time of swinging extension and improve washing efficiency, by controlling a washing mechanism so that clothes can be delivered to the next process device in a short time, basing on the position of the washing mechanism during swinging extension movement at the time on receiving signals of possible receive preparation from the following process device. CONSTITUTION:When a washing drum receives an OK signal of receive preparation from a dewatering machine when it is in the forward revolution mode of swinging extension, the revolutional position of the drum at this time is known by the control disc of operational controller. Hence, the drum is regulated so that the revolutional motion of swinging extension gets 450 deg.+360 deg. for instance in the total and clothes are fed into the dewatering machine at this revolutional position. On the other hand, when it receives an OK signal at the reverse revolution mode of swinging extension, the reverse mode operation stops and the drum is rotated in the forward direction so that the revolutional angle of the drum by the reverse revolution is compensated for by 100 deg. for instance or so that the revolutional angle gets 100 deg.+360 deg. in the total. At this revolutional position, the clothes are fed in the dewatering machine.

Title: Surface treatment of iron alloy material
Inventor: ARAI TOORU
IPC: C23C10/54
Filed: 1982-07-26
Abstract: PURPOSE:To prevent local erosion in the case in which iron alloy materials are used in contact with a molten Al bath in a method for heating the iron alloy materials in the presence of the group Va elements by applying Cr plating beforehand on the iron alloy materials. CONSTITUTION:Cr plating is carried out on the surfaces of an iron alloy material contg. >=0.2wt% C and the material having the Cr layer is heated in the presence of the group Va elements. Then, the C in the Cr carbide layer is diffused to change the Cr layer to a Cr carbide and to bond the C in the Cr carbide layer and the group Va elements, whereby the carbide layer of the group Va elements is further formed on the Cr carbide layer. Since the iron alloy material of the base material, the Cr carbide layer and the carbide layer of the group Va elements are bound to one body metallurgically in the iron alloy member obtained by this method, the material has high mechnical strength and remarkably improved peeling properties. Even if there are defective parts in both layers formed, these parts hardly match and therefore this iron alloy member is extremely highly resistant to corrosion.

IPC: G01N17/00
Filed: 1981-08-21
Abstract: PURPOSE:To sharply reduce a tank and to lengthen a seal life by decreasing a displacement at a seal part, by a method wherein one end of a receptacle, in which high-temperature high-pressure water is contained, is secured to a test piece, and the other end can slide over the test piece. CONSTITUTION:A projection 20 is formed on a part of a test piece 10, and one end of a cylinder 13 is secured to the test piece through the medium of an end plate 11 and a seal 12. A plural number of openings is formed in a part of the cylinder 13, and forms an outlet and an inlet for high-pressure water. The other end of the cylinder 13 is structured such that a sleeve 16 and a seal 18 are attached to it by a box nut 17 or the like, and allows a relative displacement to the test piece. This eliminates the need to mount a load mechanism in the cylinder 13, and enables the sharp reduction in the size of a conventional tank. A displacement at the sealed part is only the elastic deformation of the test piece, and it extremely decreases when compared with that produced by a conventional method.

Title: Electronic copying machine having editing function
Inventor: TANIMOTO YOSHIHIRO
IPC: G06F3/0488
Filed: 1986-06-05
Abstract: PURPOSE:To form an accurate editing image based on specification by simple operation by relatively moving an original platen or an optical system, measuring the timing of image formation for editing and forming an image based on the timing. CONSTITUTION:A position specifying means is moved on the surface of an original to specify the position of the original to be edited, e.g. the leading and part of the original to be moved. When a copy button is depressed after the specification, the original platen or the optical system is relatively moved based on the positional specification and a moving distance on the original surface at the time of movement is measured as the relative moving timing for the original platen or a photosensitive drum and an edited image is formed by an image forming means based on the measured timing. Since the timing of image formation for editing is measured, an accurate edited image based on the specification can be obtained even if the device has a trouble, i.e. when an oil film on a bearing part is lacking at the time of restart of the device after being stopped for a long period and the load of a driving system is increased.

Title: Punch
Inventor: KOSHIRAE MASATAKA
IPC: B26F1/34
Filed: 1988-05-27
Abstract: PURPOSE:To make the stroke of a punch pin smaller and sheets of paper in various thickness cuttable by installing an almost V-shaped groove partially different in inclination so as to become larger than a tilt line connecting an edge tip, having a V-shaped bottom and being provided with a peripheral part tilt in the peripheral edge, to the deepest point, in a tip part of the punch pin. CONSTITUTION:An almost V-shaped groove 16, different in inclination partially so as to become larger than a tilt line connecting an edge tip, having a V-shaped bottom and being provided with a peripheral part tilt in the peripheral edge, to the deepest point, is formed in a tip part of a punch pin 1. In consequence, even if the tip edge is very sharp, a distance (t) from the tip to a bottom of the groove 16 will get off a very short one, so that such requirement as lengthening a stroke of the punch pin 1 is brought to nothing. In addition, against thick paper, a sharp edge effectively works, while the V-shaped groove 16 works with thin paper properly, thereby punching the thin paper without entailing any disorder of the cut end.

Title: Detecting device for toner residual quantity
Inventor: KANAI HIDEFUMI
IPC: G03G15/09
Filed: 1981-08-19
Abstract: PURPOSE:To simplify the constitution, by using a voltage, which is induced in a detecting material in a developer with the AC voltage applied to a developing roll, to detect the quantity of a residual toner. CONSTITUTION:The AC voltage from an AC bias power source ACS is applied to a developing roller 12, and a detecting conductor 15 is arranged so as to face to the developing roller 12, and an induced voltage is generated in the detecting conductor 15. Since a toner 10 contains iron, the magnetic permeability is changed in accordance with the quantity of the toner, and the induced voltage generated in the conductor 15 is changed. That is, the detecting conductor 15 is provided in a developer, and the quantity of the residual toner is detected by the voltage induced in the conductor 15. Thus, the constitution is simplified because a new AC power source is not required for detection.
