Title: Power supply for electric discharge machining
Inventor: TSURUMOTO KAZUO
IPC: B23H1/02
Filed: 1983-05-04
Abstract: PURPOSE:To make machining surface accuracy and roughness on a work improvable, by comparing a peak current of a discharge current with a reference value, while correcting variations in the peak current with the DC power voltage of a switching circuit. CONSTITUTION:A variation in the current between poles is detected as a voltage variation by a current-voltage converter circuit 9 of a switching circuit by means of a semiconductor switching element 4 and outputted as voltage Vp equivalent to a peak current value by a peak value detection circuit 10. On the other hand, when each on-time range of voltage E of a DC power source 13 and the semiconductor switching element 4 is determined, a reference value Vr in the peak current which is originally to be given to space between poles is as well determined. Now, if Vp<Vr is the case because of inductance's variations or the like, an output Vo of a differential amplifier 11 becomes negative whereby, with action of an analogue switch, the DC power source 13 fitted with an automatic voltage regulator heightens its output voltage till it comes into an equation Vo=0. Thus, such a discharge current pulse as being uniform and evenness in size is securable so that machining accuracy and surface roughness both can be improved.

Title: Form supply device
Inventor: TAMURA TETSUYA
IPC: G06Q40/00
Filed: 1995-04-04
Abstract: PURPOSE: To provide the form supply device which prevents a foreign matter such as a pencil and a seal from entering the device. CONSTITUTION: This form supply device has plural shutters 13 and 14 which are arranged at an insertion slot 11 for media 55, 55a, and 55b, sensors which are arranged corresponding to the respective shutters 13 and 14 and detect the media 55, 55a, and 55b, and a driving means and a controller which operate the shutters 13 and 14 independently of each other. The controller is equipped with a shutter switching means which selectively switches the shutters 13 and 14 corresponding to the sensors having detected the media 55, 55a, and 55b. In this case, only the shutters corresponding to the sensors having detected the media 55, 55a, and 55b are opened. The insertion slot 11 is normally closed, so even if an operator falls a foreign matter by mistake while operating a printer device, the foreign matter never enters the device main body through the insertion slot 11.

Title: Manufacture of stem
Inventor: TAGUCHI NOBORU
IPC: H01J9/30
Filed: 1982-05-11
Abstract: PURPOSE:To manufacture hard glass stems in large quantities, by pressing powdery solder glass together with a binder, and baking and sintering the formed product. CONSTITUTION:A solder glass which is powdery low-melting glass is mixed with an organic binder such as isoamyl acetate, put together with conductor wires into a compression mold, and pressed. The pressed product is heated in a furnace to burn out the binder, and baked at an elevated temperature, e.g. at 700 deg.C. To compensate the deformation of the pressed product during the baking process, it is necessary to consider the deformation in the design of the press mold or in the preparation of the baking mold. Since the compression molding can be carried out at high speed and the baking can be performed in one step at large quantities, the process is suitable for the mass-production of hard glass stems.

Title: Thin film device
Inventor: NAGAO EIICHI
IPC: G11B5/31
Filed: 1987-04-02
Abstract: PURPOSE:To obtain a thin film device not to be suffered from exfoliation and having excellent electromagnetic conversion characteristics, by providing on a magnetic film an insulation material film having a smaller internal stress than that of the magnetic film. CONSTITUTION:Permalloy is evaporated by the sputtering only in the determined thickness (at least 0.5 mum) in order to form an upper magnetic pole. Since the sputter film 10 has an internal stress, in terms of the compression stress, of the film as large as at least 4X10<9> dyn/cm<2> which is about 10 times that of the plated films 3, 6, in case a film is formed on a substrate including the stepped portion of surface of 5 mum or more like the upper pole such as a thin film magnetic head, the film itself is exfoliated at the stepped portion. Such exfoliation of film can almost perfectly be prevented by forming permalloy sputter film and then forming consequently an insulator film 11 having an inter nal stress of 2X10<9> dyn/cm<2> or less by the sputtering method. Thereby, a thin film device which has excellent electromagnetic characteristic and does not show exfoliation can be obtained.

Title: A/d converter
Inventor: YASUDA AKIRA
IPC: H03M1/36
Filed: 1991-04-12
Abstract: PURPOSE:To constitute an A/D converter with a comparatively few resistors by generating a digital signal based on the combination of a voltage division output being a minimum level difference between a 1st reference voltage division output group and a 3rd reference voltage division output group. CONSTITUTION:The reference voltage of a 1st voltage source 1 is divided equally to (m) (m is a natural number) and the divisions are outputted to a comparator means 2 as a 1st reference voltage division output group. The 1st reference voltage division output group forms a main voltage scale. The reference voltage of a 2nd voltage source 3 is divided equally to (n) (n is a natural number) and the divisions are outputted to a level shifting means 2 as a 2nd reference voltage division output group. The level shifting means 4 shifts the entire level of the 2nd reference voltage division output group in response to an input voltage and gives the result to a comparator means 2 as a 3rd reference voltage division output group. The 3rd reference voltage division output group forms a subvoltage scale whose entire part is moved by a level shift. Every time an output from the comparator means 2 is fed to an encoding means 5, the means 5 outputs a binary number corresponding thereto as a digital output. Thus, a digital signal in response to the input voltage is obtained.

Abstract: PURPOSE:To make a non-magnetic thin film on the substrate surface by adding the bias voltage to an electrode to mount the substrate and sputtering. CONSTITUTION:A substrate 1 is mounted on an electrode 14 in a vacuum tank 13. By facing to this, a non-magnetic target 15 of Cr is arranged. The evacuation is performed and Ar is introduced.

The particle of the non-magnetic substrate is driven out, accumulated on the surface of the substance 1 and a non-magnetic thin film 5 is formed. The organization of the thin film is dense, and the grain boundary diffusion into the non-magnetic thin film of a low melting point filled onto the film is suppressed. Then, a substrate crack and the deterioration of the magnetic characteristic of a soft magnetic thin film is suppressed.

Title: Plasticity element
Inventor: TAOMOTO AKIRA
IPC: C23C14/08
Filed: 1989-03-30
Abstract: PURPOSE:To impart plasticity to a single element by using an organic film whose resistance is changed when an electric field is applied and whose state is changed at different speeds when its resistance is changed from a high- resistance state to a low-resistance state and when its resistance is changed from the low-resistance state to the high-resistance state. CONSTITUTION:When an electric field is applied between a lower-part electrode 2 and an upper-part electrode 4 of a sandwich electrode for voltage application use, an organic functional substance 3 changes its state, and its resistance is changed. When it is arranged that a high-resistance state corresponds to '0' and that a low-resistance state corresponds to '1', the substance acts as a memory. Since a state of '0' and that of '1' are kept as they are as long as a reverse electric field is not applied, they acts as memories. The state of '0' is stable even when it is left for many hours; however, the state of '1' is changed to the state of '0' when it is left for several hours to several days; as a result, both states of '0' and '1' are not stable; the stored state of '1' is gradually changed to the state of '0'. Thereby, it is possible to impart plasticity to a single element.
