Title: Manufacture of magnetic disk substrate
Inventor: NISHIMOTO KOUZOU
IPC: C22F1/04
Filed: 1982-12-16
Abstract: PURPOSE:To obtain the titled substrate whose surface roughness would not be deteriorated after it has been subjected to a step of forming an oxide magnetic thin film medium, by forming an anodized film on the surface of an Al alloy plate, and performing heat treatment under specified conditions prior to the planishing of the anodized film. CONSTITUTION:The process of manufacturing a substrate includes a heat treatment step between an anodizing step as in the conventional process and a planishing step. In this heat treatment step, the anodized Al alloy plate is heat- treated at higher temperature or longer period in comparison to the heat treatment that will be carried out in the subsequent medium forming step. The thus heat-treated Al alloy plate is planished to obtain a disk substrate. After an iron oxide magnetic thin film mainly consisting of Fe3O4 is formed on the disk substrate, it is heat-treated to obtain an iron oxide film mainly consisting of gamma- Fe2O3. The surface roughness of the thus produced magnetic disk is the same as the surface roughness of the substrate, and deterioration of the surface roughness would not be observed at all.

Title: Preparation of transmission type surface relief diffraction grating
Inventor: AMAKO ATSUSHI
IPC: G02B6/122
Filed: 1986-09-18
Abstract: PURPOSE:To select and use a desired incident angle by a simple process, by generating a peak of a diffraction efficiency/incident angle characteristic in two parts by controlling the depth of a grating groove of diffraction grating, and also, shifting an incident angle generated by the peak part. CONSTITUTION:When depth (h) of a grating groove of a diffraction grating is changed gradually, a peak of the diffraction efficiency of a diffraction efficiency/incident angle thetai characteristic is increased to two from one, and also, a value of two peaks becomes high, and a peak position is also varied. This phenomenon is different by not only the depth (h) of the grating groove, but also a refractive index (n) of a material to be used. Accordingly, by controlling the depth (h) of the grating groove or selecting the material to be used, two peaks of the diffraction efficiency can be shifted to a desired incident angle thetai. Also, the angle shift can be realized by only increasing the depth (h) of the groove in a state that a shape of the grating has been held symmetrically, therefore, the manufacturing process is extremely simple, and also, as for the manufacturing method, dry etching is better than wet etching.

IPC: B29C45/50
Filed: 1986-09-19
Abstract: PURPOSE:To prevent an improper molded product from being produced at the initial time by detecting the temperature of a metal mold to judge whether it is an initial period of injection molding or a stable period, and increasing the injection molding pressure larger than a set value in case of the initial period. CONSTITUTION:A judging unit judges whether it is an initial period of injection molding where the mold temperature is a predetermined value or lower, or a stable period where the temperature arrives at the predetermined value, an automatic correction unit is operated in case of the initial period to inject at the injection pressure larger than that of the stable period. Since the initial injection molding pressure is automatically corrected, it can prevent an improper molded product from being produced.

IPC: G06K15/00
Filed: 1986-09-19
Abstract: PURPOSE:To prevent a case of overlapped printing from being generated at the time of printing a system output file data, by performing paper supplying control before printing is performed, according to a paper supplying instruction means, when the data held by a control information holding means is designated as a 'post-processing'. CONSTITUTION:In a processing part 1 which processes an application program 3, a sequential file printing processing part 4, a system output file printing processing part 5, and an advancing clause holding part 6, are provided. At the time of printing the system output file data as 4' in figure, after the printing of an 'AFTER ADVANCING' type WRITE instruction as 3' in figure, since 'AFTER' is posted when the system output file printing processing part 4 refers the advancing clause holding part 6, first of all, control of one row paper feeding is performed before printing, then the system output file data is printed. Thus, since one row paper feeding is performed first before printing, for example, when the 'AFTER' is instructed, fitting the designated format of the WRITE instruction executed previously, the overlapped printing can be prevented from occurring.

Filed: 1984-10-23
Abstract: PURPOSE:To prevent a tube from being deformed, by securing and clamping a part where a tube has been heat-shrunk to the outer circumference of a notched section of a sheave by a split ring. CONSTITUTION:A roll 1 is rotated at a speed on the order of 10rpm and after one end of a tube 2 is heat-shrunk by hot air blown from a nozzle 5, the rotation of the roll 1 is stopped and immediately a split ring 3 is fitted to a notch section A of a sheave 1e of 1f where the one end of the tube 2 is present so that the end is clamped securely. Then the roll 1 is again rotated, and while hot air is blown from a nozzle 5 inclined at an angle of 45-60 deg. to the axis of the roll 1 and directed toward the secured split ring 3, the nozzle 5 is moved at a constant speed from the side where the split ring 3 is present toward the other side. Thus, foreign matter or air can be positively prevented from entering between the barrel outer surface of the roll and the tube inner surface, and the tube can be secured, so that the tube would not be deformed in use.

Title: Surface-wave motor
Inventor: SATO SHIGEMASA
IPC: H01L41/09
Filed: 1986-09-19
Abstract: PURPOSE:To improve the efficiency of a surface-wave motor by forming ring- shaped elastic bodies constituting a stator and a rotor by a material having a low elastic modulus such as a synthetic resin. CONSTITUTION:When voltage having predetermined frequency is applied to a voltage element 15, a vibrating section 25 and the piezoelectric element 15 are bent and vibrated integrally by the application of voltage, and the mass point of the surface (a drive surface) of the vibrating section 25 conducts the displacement of elliptic motion. A rotor 50 brought into pressure-contact with the surface is turned relatively to a stator 10 by the elliptic motion, thus obtaining revolving torque. Since a material having a low elastic modulus is employed as a ring-shaped elastic body 20, the quantity of deformation acquired by the drive surface of the stator 10 is made larger than the same quantity of deflection (quantity of deformation) of the piezoelectric element 15 by several times. Accordingly, an output from a surface-wave motor is increased.
