Title: Built-up type piston for internal combustion engine
Inventor: KURUTO MAIAA
IPC: F02F3/00
Filed: 1995-08-16
Abstract: PROBLEM TO BE SOLVED: To protect a piston from wearing out by providing an inexpensive and highly resistant layer by allowing a piston-upper part made of iron material to abut on a piston-lower part made of light metal or cast iron through a mounting surface to connect them by a screw, and covering at least one mounting surface with a layer made of a cured resin which is mixed with a solid lubricant. SOLUTION: A piston-upper part 1 provided with an inner ring rib 2 is connected to a piston-lower part 4 through a screw 3. For example, a layer 6 made of a cured resin which is mixed with a solid lubricant such as graphite, is welded to a ring-like abutting surface of the piston-lower part 4, for example, by the sputtering method. Contact surfaces 8, 9 can also be additionally laminated. The layer 6 has the thickness of 10 μm to 30 μm, and the proportion of solid lubricant particles is set from 30 wt.% to 60 wt.%. As a binder, polyimide which can be cured, can be used. In this way, the layer for the mounting surface between the piston-upper part and the piston-lower part can be formed inexpensively and without requiring many labors.

IPC: B41J2/075
Filed: 1998-07-24
Abstract: PROBLEM TO BE SOLVED: To eject ink stably regardless of environmental temperature fluctuation through a simple arrangement with small number of parts without requiring any additional part or control circuit by supporting a pressure regulation spring on a case expanding/contracting depending on the temperature thereby reducing the pressing force of the spring and the output pressure as the temperature rises. SOLUTION: In order to suppress pressure fluctuation of ink being supplied to a nozzle, an ink pressure regulation unit 2 for regulating the output pressure of ink depending on temperature fluctuation regulates pressurized ink supplied to an inlet 202 by varying the conduction gap between a pilot valve 203 and a valve seat 204 before delivering ink to an outlet 205. A pressure regulation spring 212 increases the conduction gap by pushing down a plunger 208 thereby pushing down the valve 203 through a pilot pin. A case 210 is molded of synthetic resin to expand/contract in the longitudinal direction of the spring 212 depending on the temperature and arranged such that the pressing force of the spring 212 decreases as the temperature rises and the viscosity of ink is not varied by the environmental temperature.

IPC: F25D11/02
Filed: 1996-08-08
Abstract: PROBLEM TO BE SOLVED: To uniformize temperature of each space by detecting the temperature of each space in a chamber with temperature detection means and controlling with control means opening/closing of a damper for opening/closing a suction inlet for cold air to the cold air supply duct in each space based upon the detected temperature. SOLUTION: An upper stage duct 21 is opened and closed with an up damper 20A and a lower stage duct 22 is opened and closed with an LR damper 20B. A temperature detecting element A24 and a temperature detecting element B25 are disposed on the upper stage 23 and on the lower stage 26 receptively. A cold air blowoff outlet 9 is provided on the upper stage duct 21 and on the lower stage duct 22 to blow out cold air to each portion. When temperatures of the temperature detecting element A24 and the temperature detecting element B25 are higher than a set value, a cold air circulating fan 5 disposed in the freezing chamber 3 is rotated to open the UP damper 20A and the LR damper 20B. Hereby, the temperature is lowered to the set value. When the temperature becomes lower than the set value, the UP damper 20A and the LR damper 20B are closed.  Thus, temperatures of the upper stage 23 and the lower stage 26 are uniformized.

When no coincidence is obtained between both codes, the reading/writing actions are inhibited partly or totally to a memory cell array 15. This inhibition state is released in case the coincidence is obtained between both codes. Thus the data can be surely protected by means of a single IC memory and with use of the constitution of a conventional pin and the arrangement of these pins.

Abstract: PURPOSE:To shorten the time of defrosting operation, by a method wherein the air flow rate of an indoor side fan is reduced immediately before the defrosting operation, in which a four-way valve is switched to change a cycle into a reversed cycle, during heating operation. CONSTITUTION:When the frosting of an outdoor side heat exchanger is advanced, the temperature of a temperature sensitive unit 10 becomes lower than a predetermined temperature and the time of defrosting cycle is counted by a timer 10B during heating operation, a relay 9 is switched to switch the tap 8A of an indoor side fan 8 to the tap 8B of the same whereby the air rate of indoor side is reduced. When the elapse of heat accumulating time is counted by the timer 10B, the indoor side fan 8 as well as an outdoor side fan 7 are stopped and a four-way valve 2 is switched whereby defrosting operation is started. When the defrosting is finished and the temperature of the temperature sensitive unit 10A becomes higher than a predetermined temperature, a defrosting detecting unit 10 switches the four-way valve 2 and operates the indoor and outdoor fans 8, 7 to effect heating operation. According to this method, amount of heat, accumulating by heat accumulating operation, is supplied to the outdoor side heat exchanger 5 in the defrosting operation after the switching of the four-way valve 2, therefore, the amount of supplying heat is increased and the time of defrosting may be shortened.

IPC: F24C7/04
Filed: 1996-08-08
Abstract: PROBLEM TO BE SOLVED: To wholly raise temperature without concentrated heating for foods by achieving weak fire operation only with a lower heater and circulating air in a heating chamber. SOLUTION: In weak fire operation (soft mode), an upper heater continues off operation while a lower heater 6 continues on operation. A fan 12 is actuated to circulate air in a heating chamber 1. The air in the heating chamber 1 is circulated with weak fire only of the lower heater 6 so that the whole of the foods is gradually heated without permitting the surface of the foods to be overheated. Thus, the foods are wholly raised in temperature without being heated in a concentrated manner. Hereby, thawing of frozen foods is ensured. Temperature in the heating chamber 1 is about 220 deg.C and ensures thawing for about 15 minutes.
