Patent JP-S56103544-A (JP)
Title: Double-wave simultaneous receiver
Inventor: TSUNO MASAHIKO
IPC: H04B1/40
Filed: 1980-01-21
Abstract: PURPOSE:To increase the efficiency of reception, by receiving simultaneously the signals of two transmission stations that have a mutual approximation of the transmission frequency between the 1st receiver and the 2nd receiver which uses the output of the frequency mixing part of the 1st receiver for the input. CONSTITUTION:The signal X to be modulated having the frequency fX is supplied through an antenna, and the frequency of the variable frequency oscillation part VFO1 is set to fV1. Thus the output of the frequency mixing part MIX1 becomes a wide-band signal centering on X[fV1-fX]. Then the fV1 is varied to make the intermediate frequency of the filter FIL2 equal to fV1-fX. Thus the output signal of the MIX1 can pass through the filter FIL1, and the signal X is received by the 1st superheterodyne receiver. At this moment, the 2nd receiver uses the output of the MIX1 for its input. At the same time, the signal Y[fY] to be modulated having the frequency fY a little slower than fX is supplied through the antenna, and thus the  output of the MIX1 is turned into the signal into which Y[fV1-fY] centering on X[fV1-fX] is mixed. Thus the 2nd receiver can receive Y[fV1-fY].

Filed: 1984-01-17
Abstract: PURPOSE:To form an image having high quality with simple constitution in a non-contact transfer type developing method of an electrostatic laten image by selecting the charge density per unit volume of a toner in a way as to satisfy prescribed conditions. CONSTITUTION:The thickness df of a toner layer on a toner support 3 having a function relation with the DC bias current VD to be impressed, the potential Vmax in the image part of a charge holding body 2 and the potential Vmin in the non- image part are determined.

Title: Inverting developing method
Inventor: ASANAE MASUMI
IPC: G03G15/06
Filed: 1986-01-14
Abstract: PURPOSE:To obtain an inverting developing method which has high resolution and does not generate the dust at the circumference of an image by making an image support into a negative charging characteristic, cold-pressure-fixing a magnetic toner and making it into a positive charging characteristic. CONSTITUTION:By rotating relatively a sleeve 4 and a permanent magnet member 5, a toner 3 accommodated in a toner tank 2 is pulled out onto a sleeve 4 and conveyed toward a developing gap D. To the toner 3, the characteristic to positively charge the polarity reverse to a static latent image formed on a photoconductive layer 1a is given, and when the toner 3 having the positive charge arrives at the developing area, the toner is stuck to the non-image part of the photoconductive layer 1a and a toner image is formed. Next, the toner image is transferred by the rotation of a photosensitive body drum 1 and fixed by a pressure fixing means. The used magnetic toner 3 is preferably one with a friction charging quantity of 2-20muc/g when the toner is measured by a blowing-off method and the charging voltage on the sleeve 4 is 5-60V. Thus, the inverting image can be obtained having a high quality image, especially, high resolution and hardly generating dust around the circumference of the image.

Title: Preparation of polyester
Inventor: MURAKAMI MASASHIGE
IPC: C08G63/78
Filed: 1980-01-24
Abstract: PURPOSE: To prevent the vacuum circuit of a condensation polymerization system from being clogged and to prevent the glycol distilled from escaping, by specifying the temperature of the cooling water at the outlet of a condenser for the distillate, in the condensation polymerization of a glycol ester of a discarboxylic acid.  
     CONSTITUTION: In the preparation of a polyester by the batchwise condensation polymerization of a glycol ester of a discarboxylic acid, the peak temperature of the cooling water at the outlet of a condenser for the glycol distilled, is adjusted to be 40W100°C. When the peak temperature of the cooling water at the outlet of said condenser <40°C, it causes the clogging of the vacuum circuit because a glycol ester or a low polymer thereof is inefficiently caught by the glycol distilled. Said temperature over 100°C is undesirable because the distilled glycol itself is not condensable and escapes out of the system through the vacuum circuit.

Title: Food frier using high-pressure hot water as heating medium
Inventor: MIURA TAMOTSU
IPC: F28D1/06
Filed: 1988-01-14
Abstract: PURPOSE:To clean a working field due to the indirect heating of a frying oil, to safely and easily adjust the temperature of the oil, and to make heating expenditures <=a half compared with those of electric heat by using high- pressure hot water as a heating medium, and circulating the medium in a circulation system set in the oil tank of a food frier. CONSTITUTION:When a forcibly circulating pump 3 is driven, the water in the system is sent to a heat receiving heat exchanger 5, heated by a burner 4, and sent to a pressure-adjusted hot water tank 6. Since the original pressure of an inactive gas bomb 8 is adjusted by the action of a pressure adjusting valve 9, and the tank is always set at a prescribed pressure, the water in the tank does not boil at <=a set saturation temperature. The hot water produced from the bottom part of the pressure-adjusted hot water tank 6 passes through an oil heater 7 in an oil tank 1, indirectly heats the frying oil, and returns to a forcibly circulating pump 3. Due to the circulating flow, the frying oil in the oil tank 1 is heated to the necessary temperature, it is maintained, adjusted, and delicious fried food is obtained.

Filed: 1982-01-22
Abstract: PURPOSE:To prevent grain boundary oxidation and to enable high-carbon carburizing easily by repeating processes of heating steel to be treated in a vacuum furnace of carburizing temperature and introducing hydrocarbon into the furnace and then repeatedly cooling by a neutral gas. CONSTITUTION:A work (steel) to be carburized is put into a vacuum carburizing furnace set at carburizing temperatures of about 900-1,050 deg.C, and the work is heated in vacuum of about 0.5 Torr. Then, a hydrocarbon gas such as methane, etc. is introduced into the furnace, and carburizing and diffusion are repeated several times. By this long-time carburizing, development of reticulated cementite and resultant formation of brittle texture are prevented. By repeated carburizing and diffusion, reticulated cementite is dissolved in austenite particles at the time of diffusion. Consequently, reticulated cementite is prevented from becoming coarse. After carburizing, the work is cooled by a neutral gas such as N2 etc. Then, it is heated again to the carburizing temperature, carburized in C potential atmosphere exceeding Acm, and diffused in vacuum. This is repeated several times. After repeating heating and cooling three times in high-carbon carburizing cycle, hardening cycle and oil quenching are performed.
