Title: Structure of metallic mold for half melt molding
Inventor: NIWA SHOZO
IPC: B22D18/02
Filed: 1989-06-12
Abstract: PURPOSE:To obtain a molding having good mechanical properties by forming the communicating part to a stock holding chamber of a passage connecting between the stock holding chamber and a forming mold to the sectional area smaller than the sectional area in the outlet of the holding chamber and forming the communicating part of this passage to a forming mold to the sectional area larger than the sectional area in the outlet of the forming mold. CONSTITUTION:The forming mold 11 and an upper mold 12 are kept at the half melting temp. of the stock by a heater 15. After the stock is heated to the half melting temp. in a separately prepd. furnace, the stock is put into the stock holding chamber 12b. An upper punch 13 is lowered to push the stock 14 through the passage 12a into a recess 11a. While drawing is executed in two stages in the above-mentioned embodiment, the drawing in >=3 steps is equally good alternative and the adoption of the structure to decrease the sectional area of the passage gradually toward the forming mold is equally satisfactory. The drawing rate at the time of extrusion during the molding of the stock is increased in this way while the molding pressure is kept low. The molding having the good mechanical properties, such as tensile strength, is thus obtd.

CONSTITUTION:This method is a production method for a small diameter long sized corrosion resistant cast steel pipe consisting of two phase cast stainless steel contg. 5-30% (area rate) ferrite phase. The molten cast steel is subjected to centrifugal casting and after the steel solidifies, the steel is cooled at the average cooling rate controlled to >=20 deg.C/min. down to 600 deg.C. The resulted casting pipe is subjected to a solution heat treatment then to cold working, and is thus worked to an intended small bore long sized pipe. The pipe is subjected to a recrystallization fining treatment prior to cold working or in the mid-way of the cold working according to need. The crystal grains of the casting pipe are fined by the above-described control of the cooling rate, whereby the sufficient processability to make the pipe withstand the succeeding cold working is provided. Otherwise the processability is further improved by the refining treatment, whereby the working to the small bore long sized pipe is accomplished easily and smoothly.

Filed: 1993-06-18
Abstract: PURPOSE:To compensate the temperature and frequency characteristic of a conversion gain and to improve the temperature fluctuation and frequency characteristic of a device gain by controlling a variable attenuator and a variable equalizer corresponding to the output frequency of a local oscillator and the input value of a temperature sensor. CONSTITUTION:A control circuit 6 sets the output frequency of a local oscillator 5, sets the conversion frequency of the device and outputs a control voltage through an adder 8 to a variable attenuator 1. Then, the conversion gain of the entire device is set so as to be a desired value. Namely, a corrected attenuation amount corresponding to the frequency characteristic of a high frequency amplifier 4 is held in a prescribed form at the circuit 6 as a parameter corresponding to the output frequency of the oscillator 5. Together with the setting of the output frequency of the oscillator 5, the corrected attenuation amount corresponding to the conversion gain set value of the device set from a remote controller or the like to the variable attenuator 1 is outputted to the attenuator 1. This output is added with the output of a temperature sensor 7 by the adder 8 and inputted to the attenuator 1. As a result, the temperature characteristic and the frequency characteristic can be improved regardless of the conversion gain set value and conversion frequency of the device.
