Title: Heat resistant magnesium alloy molded member, heat resistant magnesium alloy used for the molding and molding method therefor
Inventor: SAKAMOTO KAZUO
IPC: C22C23/02
Filed: 1996-04-04
Abstract: PROBLEM TO BE SOLVED: To produce a heat resistant Mg allay molded member excellent in moldability and extensibility while its creep resistance is secured, in an Mg-Al- Ca-Mn alloy, by specifying its compsn. and regulating the ratio of Ca/Al to a specified value or below. SOLUTION: An Mg alloy having a compsn. contg., by weight, 2 to 6% Al, 0.5 to 4% Ca, and the balance Mg, and in which the ratio of Ca/Al is regulated to <=0.8 is subjected to half-melting injection molding at a liquids temp. or below in which solid phases and liq. phases are coexistent. In this way, the heat resistant Mg alloy molded member such as automobile transmission parts or engine parts excellent in creep resistance can be obtd. Al is required by >=2%, but, in the case of >6%, its elongation deteriorates even if the half- melting injection molding is executed. Ca is added for increasing its high temp. strength tending toward reduction accompanying the addition of Mg to Al, but, for preventing the reduction of its moldability and the elongation of the molded member, the ratio of Ca/Al is required to be suppressed to <=0.8.  Moreover, <=0.15% Sr is preferably added as a refining agent.

Title: Method of controlling fuel injection quantity
Inventor: MIYAKI MASAHIKO
IPC: F02M59/36
Filed: 1982-05-17
Abstract: PURPOSE:To make it possible to detect the fuel injection time with high accuracy and stability by fitting a stress-voltage converting element to a cam member transmitting a fuel compression movement to a plunger. CONSTITUTION:The plunger 2 rises up and the fuel within a pressure chamber 5 is compressed to a high pressure. The pressure applied to the plunger 2 is added to a roller pin 31 holding a roller 32 and a roller holder 13 supporting the roller pin 31. Since a stress in correspondence to the pressure of the fuel applied to the tip end of the plunger 2 is generated at the holding part of the roller holder 13, the thus generated stress is detected by the stress-voltage converting element 20. By this procedure, the fuel injection time can be detected with high accuracy and stability.

Title: Ceramic print coating apparatus
Inventor: KOBAYASHI AKIRA
IPC: H01G13/00
Filed: 1995-04-07
Abstract: PURPOSE: To form a uniform green sheet which has small thickness irregularity by extruding ceramic paint containing specific concentration of ceramic power from a coating head to the one surface side of a running flexible support. CONSTITUTION: A coating head 10 coats the one surface side (a) of a flexible support 19 which runs in one direction F1 with ceramic paint 17a by extruding. Since the paint 17a contains 1 to 20vol.% of ceramic powder, its viscosity is extremely lower than that of the conventional ceramic paint, its drying shrinkage factor is large, and to obtain the same thickness after drying, the supplying amount can be increased. Thus, the gap between the end of the head 10 and the support 19 can be increased, and the streak due to the head 10 can be avoided. Since the coating thickness of the paint 17a can be increased, the peeling of a ceramic paint layer scarcely occurs, and a pinhole scarcely occurs.

Title: Emergency stopper for ship
Inventor: USHIYAMA KAZUO
IPC: A61G3/00
Filed: 1979-06-29
Abstract: PURPOSE: To effectively, safely, stop a ship in case of emergency by rotating and expanding the braking flap which is provided below the water level on both sides of the ship by the effect of external water.  
     CONSTITUTION: The braking flap 11 is provided below the water level on both sides of the hull 12 so as to rotate around the pin 13 as a vertical axis. A hollow part (a) with a fan-shaped horizontal cross section for admitting the rear part 11r of the flap 11 is formed in the ship body. When the flap 11 rotates, a small gap γ 1  is formed between the rear end and the curved wall surface 12c of the hollow part (a) of the ship. When the hull stops emergently, the ram 18a is withdrawn by the operation of the hydraulic cylinder 18 and a force which opens the flap 11 by the repulsion force of the buffer body 19 is applied. Both this force and the force resulted by the pressure of the sea water which flows into the ship the flap 11 begins to open. Since the above-stated gap γ 1  is small, however, the flap 11 is prevented from opening suddenly.

Title: Low pressure stage refrigerant system in double-pressure type freezer device
Inventor: TAKAMI YOSHIO
IPC: F25B7/00
Filed: 1991-04-16
Abstract: PURPOSE:To eliminate frequent energization and stopping of a compressor and improve a freezing efficiency in a low pressure side refrigerant system in the double-pressure type freezer device by a method wherein a capillary tube and a check valve are connected in parallel to each other above a refrigerant pipe at a low pressure side between the compressor and an expansion tank. CONSTITUTION:Refrigerant of high pressure discharged from a compressor 19 in a low pressure side refrigerant system 18 enters a cascade condensor 21, where this refrigerant heat exchanges with refrigerant of a high pressure side refrigerant system 30, the former refrigerant is cooled and liquified, thereafter the refrigerant passes through an expansion valve 22 and is sent to an evaporator 23. Air in a refrigerator is cooled by it and the refrigerant is returned to the compressor 19. In this case, when the compressor 19 is stopped, high pressure within a refrigerant pipe 24a is released from a relief valve 27 into an expansion tank 26, a high pressure within a refrigerant pipe 24b is released through a check valve 29 into the expansion tank 26 so as to decrease the pressure within the low pressure side refrigerant system 18 to a value lower than a predetermined pressure. When the compressor 19 is energized, the pressure within the expansion tank 26 is gradually sucked into the compressor 19 through a capillary tube 28 and then a continuous operation of the compressor 19 is enabled.

IPC: G04G15/00
Filed: 1981-06-01
Abstract: PURPOSE:To perform a reliable setting of a time limiting hour through an easy operation, by a method wherein, through detection of an unexisting time stored in a time limiting memory part, the unexisting time is automatically switched to  a real existing time in response to the operation of a time limiting set switch. CONSTITUTION:Through application of a clear signal by closing a power source, counters for hour, minute and second in a clock part 22 are initially set to store 1, 0 and 0 respectively, and counters 37 and 38 for hour and minute, counting 1-12, 0-59 of a time limiting memory part 39, are initially set to store 0 and 0, respectively. The unexisting time 0 of the counter 37 is detected by an unexisting time detecting part 43 for zero-detecting, and an AND gate 44 is opened through a delay circuit 44. A first pulse, setting the counter 38, from an AND gate circuit 42 corresponding to a first operation of a time limiting minute set switch 10 is applied to the counter 37 also, and the memory content of the counter 37 is automatically switched to 1 of the real existing time. This prevents the occurrence of an erroneous setting of an unexisting time, such as something after 0, and enables to perform a reliable setting of a time limiting hours through a simple operation.
