Title: Pretreatment of coating of casting and coating treatment
Inventor: KAWAI MAKOTO
IPC: C25D7/00
Filed: 1997-04-09
Abstract: PROBLEM TO BE SOLVED: To execute a pretreatment of coating of a casting with a short treatment time without generating chips, waste liquids, etc., and without using consumables, such as grinding wheels, abrasive powder and etchants, at the time of the treatment by bringing a member into pressurized contact with a casting surface, thereby plastically deforming the surface and making the ruggedness on the casting surface smaller. SOLUTION: The casting surface 22 of an aluminum cylinder is a surface under the working treatment. Projecting parts are annihilated on the casting surface 23 in the upper part of the aluminum cylinder by the pressurized contact and plastic deformation by a roller 16. Recessed parts begin to be annihilated by the build-up of the surface by the plastic deformation in the central part as well. The treatment of the recessed parts can be executed simultaneously with the compression of the projecting parts in such a manner and, therefore, the processing treatment time is short. In addition, the plastic deformation by the compression is merely applied on the casting surface 23 and, therefore, the dimensional accuracy prior to the processing treatment is not impaired and the generation of the chips, etc., is averted. Further, the casting blowholes existing at the surface layer and within the inside before coating are made extremely little and be annihilated by pressurized contact.

Title: Transmission system
Inventor: KAMEYAMA SHIGEJI
IPC: H04L5/16
Filed: 1988-04-12
Abstract: PURPOSE:To eliminate the need for the increase in the constitution scale of an outgoing/incoming station by utilizing an interblock time period in the time division multiplex bidirectional transmission for the communication of analog voice. CONSTITUTION:A line terminator 5 outputs transmission information (D10) from a DTE 6 to a transmission line 4 for a time period T1, and in this case, the TRD 51 sends a switching control circuit to a SW 53 to switch the SW 53 to the position shown in the arrow in full lines. Thus, the information D10 is sent to the transmission line 4 through the TRD 51 and the SW53 at the time period T1 and received by a line terminator 3. The line terminator 3 receives the information D10 in the time period T1 by the TRD 31 and sends the transmission information D11 of the time period T2 after the elapse of a guard time Tg to the line terminator 5. Thus, the information is sent to the transmission line via the TRA and SW in an interblock time period except the transmission time period and the reception time period in a prescribed period and an analog voice signal in opposite direction is received simultaneously and it is not required to provide a separate ordering voice line.

IPC: H03K17/723
Filed: 1979-07-20
Abstract: PURPOSE:To obtain both the narrow- and wide-duration pulses by only one unit of the gate transformer, by connecting the capacitor and the resistance in parallel to the limit resistance of the Royer's oscillator. CONSTITUTION:The serial circuit of vibration preventing resistor 23 and capacitor 24 is connected in parallel to limit resistor 14 of the Royer's oscillator. Here the resistance value of resistor 23 is set lower than the resistance value of resistor 14 in order to obtain the necessary pulse value. As a result, the output voltage having waveform 3 is induced at the secondary side of gate transformer 21. This output voltage then receives the full-wave rectification, and thus gate signal having waveform 4 obtained by compounding the narrow- and wide-duration pulses can be obtained. In such way, both the narror- and wide-duration pulses can be obtained by only one unit of the gate transformer.
