Title: Electrorecorder
Inventor: MORI TAKASHI
IPC: B41J2/32
Filed: 1989-05-19
Abstract: PURPOSE:To improve printing quality by restraining generation of irregularity in density caused by creeping current by a method wherein the title electrorecorder is so constructed that a control means which controls a recording electrode and a return electrode by electrification is provided and electrification is performed by selecting the return electrode according to electrification control of the recording electrode. CONSTITUTION:A recording electrode 11 and a return electrode 12 are brought into pressure contact with an ink ribbon 16, and pulse voltage is impressed between the recording electrode 11 and the return electrode 12 which were selected while the ribbon 16 is being transferred. Pulse current flows to the ink ribbon 16 principally through an ink layer 14. Since a contact area to the ink ribbon 16 to the recording electrode 11 is small by comparing with the return electrode 12, current density just under the recording electrode 11 increases. Heating value is enclosed in a minute area, and density just under the recording electrode 11 suddenly increases. A signal is outputted from a CPU based on a printing form in printing, and switching transistors 17, 18 of corresponding recording electrode 11 and return electrode 12 are made to turn on. Then, by turning on only the return electrode 12 corresponding to the returned on recording electrode 11, generation of creeping current comes to be little.

Title: Communication equipment
Inventor: MINAMIZAWA FUMIHIRO
IPC: H03M7/00
Filed: 1996-05-20
Abstract: PROBLEM TO BE SOLVED: To compress multi-value image data based on an image signal read by a scanner without increasing the manufacture cost by using a voice compression function to compress voice data from a MODEM so as to compress the image data. SOLUTION: In the scanner mode, an analog image signal from a scanner 26 is fed to a gate array 24, where the signal is A/D-converted by the A/D conversion function of the gate array 24 into multi-value image data. The image data consist of picture elements each comprising 16 bits and the data are fed to a MODEM 28, in which the data are compressed by the voice compression function of the MODEM 28 and the resulting data are stored in a RAM 22 via the gate array 24. The image data are transferred to an interface 15 of a personal computer 1 via a cable 32 from an interface 25, and since the data are compressed, the transfer time is reduced and the storage capacity of a hard disk unit 16 is reduced.

Inventor: AOKI ISEO
IPC: E02D5/50
Filed: 1984-06-19
Abstract: PURPOSE:To obtain a pile having a high frictional force by a method in which a pit of almost the same diameter as a pile to be driven is drilled, a hardener is injected into the pit, and a pile is driven into the pit before the hardener hardens.

Cement mortar M is packed into the pit 2, and the pile 7 is driven into the pit 2 before the mortar M hardens. Since the mortar M is pressed into the ground against the pressure of the pit wall, the effect of the friction of the pile 7 can be enhanced.

Title: Formation of metal electrode on semiconductor
Inventor: FUJITA OSAMU
IPC: H01L21/28
Filed: 1982-07-17
Abstract: PURPOSE:To obtain an ohmic electrode having a low contact resistance by vacuum depositing a metal while the surface of a semiconductor is irradiated with light. CONSTITUTION:When Al, Zr, or Ti etc. which is easily oxidized by irradiation of ultra-violet ray is vacuum deposited on the surface of semiconductor material, it is effectively reduced by an energy of the ultraviolet ray even if an oxide layer is previously formed on the surface and an excellent ohmic contact electrode having sufficiently low contact resistance can be obtained through diffusion of generated O2 into a metal electrode formed on the surface. In this case, it can be assumed to be possible that O2 forming an oxide layer diffuses into electrode and oxidizes the electrode. But the electrode is not oxidized when the metal electrode is formed sufficiently thicker than the oxide layer, eliminating the possibility as mentioned above.
