Title: Extreme-pressure cleaning agent comprising sulfurized alkaline earth metal phenate and its production
Inventor: YAMAOKA SHINJI
IPC: C10N30/04
Filed: 1993-03-12
Abstract: PURPOSE:To prepare the subject agent which does not adversely affect a catalyst for cleaning waste gas and to provide a process for its production. CONSTITUTION:The objective agent comprises a mixture obtained by effecting the sulfurization and carbonation of an alkaline earth metal salt of a phenol having a 4-6C aliphatic hydrocarbon side chain. This agent is prepared by reacting a reactant mixture comprising this phenol, a dihydric alcohol, 0.99g. eq. or below, per g. eq. of the phenol, of an alkaline earth metal reagent and 0.1-4.0mol, per mol of the reagent, of elementary sulfur, distilling off the water and unreacted dihydric alcohol to a content of 1.99mol or below per mol of the reagent, and reacting the obtained product with carbon dioxide. Thus, a phenate-type extreme-pressure cleaning agent which can show extreme-pressure performances at least equivalent to those of conventional ZnDTp or phosphorus- containing extreme-pressure additives though it contains no phosphorus can be obtained.

Abstract: PURPOSE:To obtain a typing mechanism which can obtain stable typing quality and torque and which is difficult to be damaged without necessity of highly accurate parts by providing means for controlling hammer drive force by applying elasticity to a hammer or platen. CONSTITUTION:An initial load is applied via pins 5-1, 5-2 of a hammer 5 to a hammer spring 10 in a direction of an arrow C, and the end 10-1 of the spring becomes a contactor with a hammer cam 6. When the cam 6 is rotated in a direction of an arrow A, the hammer 5 is rotated in a direction of an arrow B, a type 1-1 is pressed on a platen 4 through a printing sheet 7, thereby starting typing. The force for the typing becomes a force corresponding to a displacement delta caused by the pin 5-2 by displacing the spring 10 via the pin 5-2. Even when the operation of the hammer 5 is isturbed by a certain reason, only the spring 10 is deflected, but the manner 5 or the like is not damaged.

Title: Cooking device with high frequency heating
Inventor: NODA TAKAMITSU
IPC: H05B6/68
Filed: 1990-03-28
Abstract: PURPOSE:To drive a magnetron within a normal range even with different AC voltage commercially supplied, by controlling the On time width of a switching element in conformity to a signal given by an anode current sensing circuit, and holding the anode current of the magnetron constant substantially. CONSTITUTION:From an anode current sensing circuit 18, the mean amperage is fed to an error amplifier 26 in a control circuit 10, which compartes the input with a set value Vr and emits a difference signal S1. This signal S1 becomes larger with higher voltage of commercial AC mains impressed on terminals T1, T2, and an On timing determining circuit 27 controls a base signal S4 so that the On time of a switching element 8 shortens. Therefore, the anode current of magnetron 15 can be suppressed to a constant value substantially even though the supply voltage impressed varies between 100-200V due to erroneous connection, and in the case of going out of the extent 80-260V, a prohibit signal S4 is issued to stop the magnetron 15 through an AND gate 28 and the switching element 8.

Title: Chopper unit
Inventor: AJIGUCHI YASUHIKO
IPC: H02M3/155
Filed: 1991-04-12
Abstract: PURPOSE:To protect a chopper element from damage by deblocking the gate signal of a load side chopper element with an ON pulse width corresponding to the residual voltage of a capacitor at the time of starting thereby suppressing discharge current of the capacitor. CONSTITUTION:When an operation command RUN goes '0', a contactor 8 turns OFF to reset an FF 17 and the gate signals G4, G5 of chopper elements 4, 5 are blocked to stop a chopper unit. At that time, a capacitor 7 is spontaneously discharged. If the chopper unit is restarted when charges remain in the capacitor 7, the FF 17 is held in reset state until a reactor current I1 reaches a predetermined level IB. Consequently, only the gate signal G4 elongates the minimum ON pulse width gradually. The gate signal G5 is outputted at a time point when I1=IB and the chopper unit enters normal operation. When the voltage is controlled to a predetermined level, the contactor 8 is turned ON. According to the invention, the chopper unit can be restarted without discharging the capacitor.

Title: Thermal head
Inventor: OGATA KAZUO
IPC: H05K1/02
Filed: 1985-04-15
Abstract: PURPOSE:To suppress the upheaval and thermal deformation cycles of the center of glass projection and the breakage of exothermic elements by repeating heating pulses by providing a glass projection of a thermal expansion coefficient with the range of 30-35X10<-7>/ deg.C for the lower part of heating elements on an insulating base plate. CONSTITUTION:A heating element 3 is formed on the top of a trapezoidal projection 2 formed on an insulating alumina base plate 1. Conductors 4 are formed on the plate 1 and the projection 2 connectedly to both ends of the heating element 3 and led to the end portion through the upside of the base plate 1. The projection 2 is made of glass powder of a thermal expansion coefficient of 30-35X10<-7>/ deg.C, having constituents, e.g., SiO2, Al2O3, B2O3 and Na2O, and a grain size distribution of 0.3-30mum with max. distribution of 6-10mum. The glass powder is melted at 950 deg.C for 8min to form the projection 2. Since the thermal expansion coefficient of the projection 2 below the heating element 3 is small, thermal deformation of the glass projection 2 can be lessened even when the temperature of the heating element is raised by application of pulse voltage.

Abstract: PURPOSE:To enable ink to fly stably by stabilizing surface potential of a recording paper by closely contacting the recording paper with a counter electrode by a method in which the counter electrode to be touched by the recording paper is shaped into a columnar form and a conductive rubber layer is formed on the surface of the counter electrode. CONSTITUTION:A columnar counter electrode 6 is horizontally provided on the center of a printer body 1, and a conductive rubber layer 8 is integrally formed on the surface of the round shaft supporter 7 of the electrode 6. A recording paper 9 is wound around the electrode 6. When electromagnets 24 and 25 are electrically energized, the recording paper 9 is sent out without slipping by the electrode 6 because the electrode 6 has the rubber layer 8 of great frictional resistance on its surface. The paper 9 is closely contacted with the electrode 6 because of the columnar form of the electrode 6, and the surface potential is kept constant all the time and no variation of voltage occurs between the electrode 6 and a recording electrode 29. Stable flying of ink from the electrode 29 to the paper 9 can thus be attained, ensuring the performance of high-quality printing.

IPC: C23C22/73
Filed: 1991-04-12
Abstract: PURPOSE:To provide simple masking constitution and to reliably prevent entrance of treating liquid to the interior of a substance to be treated. CONSTITUTION:A refrigerant inlet outlet 11 of a cooler core 1 is held by a chuck part 14 and a block joint holder 13 of a chuck jig and a masking cover 15 of the chuck part 14 is brought into contact with a piping joint block 12 of the refrigerant inlet outlet 11 to perform masking of the refrigerant inlet outlet 11. As noted above, a chuck medical curing tool has a function to hold a cooler core itself and a function to perform masking of the refrigerant inlet outlet 11, and constitution is simple. The cooler core 1 held by the chuck jig is immersed in surface treating liquid but a refrigerant inlet outlet 11 part which is held by the chuck jig and on which masking is applied is exposed from the treating liquid. The level of the treating liquid is always maintained at a constant value through overflow of liquid in a treating liquid tank. As a result, the refrigerant inlet outlet 11 part is prevented from making contact with treating liquid and the treating liquid is prevented from entering through the refrigerant inlet outlet 11 to the interior of the cooler core.
