This added with a nonionic or anionic coagulant, and the grains in the soln. contg. platinum group metal are coagulated to form a flocky coagulated body of platinum group metal. The soln. contg. the coagulated body is subjected to separation filtration operation, desirably to suction filtration operation and is separated into the solid-liq. The solid matter is, if required, baked or is moreover subjected to reducing operation.  This solid matter is added with aqua regia, the platinum group metal is dissolved, and almost the whole quantity of the objective platinum group metal is recovered.

Title: Blowing agent for expanded plastic
Inventor: NAGAYOSHI MASAYUKI
IPC: C09K3/00
Filed: 1991-05-24
Abstract: PURPOSE:To obtain a blowing agent which can give efficiently a high-expansion ratio foam by adding a specified decomposable organic blowing agent to the surface of a blowing aid insoluble in the solvent used. CONSTITUTION:A blowing agent for a foamed plastic prepared by adding N,N'- dinitropentamethylenetetramine (DPT) as a decomposable organic blowing agent to the surface of a blowing aid insoluble in the solvent used. The mechanism by which the blowing aid represented by a metallic oxide decomposes DPT is presumably such that the metallic atoms present on the surface of the metallic oxide are apt to function as acidic sites which act upon DPT like an acid and cause DPT to decompose. As the metallic oxides, metallic oxides whose metallic ions have an electronegativity of 7-14 are desirable, and aluminum oxide and zinc oxide are particularly desirable because of their cost and availability. Aluminum oxide is particularly desirable.

Title: Semiconductor laser drive circuit
Inventor: MURATA KAZUHISA
IPC: H01S5/068
Filed: 1983-06-30
Abstract: PURPOSE:To prevent inputs of overcurrents and surge currents to a semiconductor laser, and to avoid the breakage of the semiconductor laser by mounting a protective circuit at an input stage. CONSTITUTION:In a semiconductor laser drive circuit provided with a semiconductor laser 13 and a P-I-N photodiode 14, resistors 1, 2 for setting the base voltage of a transistor 3 at an input stage are selected to fixed values under the state in which both positive and negative power supplies are inputted to both (+)and (-) terminals. When negative voltage is made higher than a first set value for some reason in the circuit, the transistor 3 is brought to an ON state, and potential at a point B drops. Consequently, a protective circuit functions even when negative voltage rises, and breakdown voltage is not applied to the semiconductor laser 13. Surge currents do not flow transiently through the semiconductor laser 13 because operating currents are fed to the semiconductor 13 and the state of constant currents is brought by changing the point B into positive potential after an APC circuit is prepared so as to normally operate in the drive circuit.

IPC: G11C11/14
Filed: 1979-09-20
Abstract: PURPOSE: To enable efficient address assignment by eliminating the need to make an address search every time continuous access is attained.  
     CONSTITUTION: The number of transfer bits on a major line up to a minor loop connected at the nearest position from the write/read terminal of the major line is denoted as A, that on the major line up to a connection point on the major line linked at the farthest position as B, and a constant positive integer which is zero or a small number as C. In this case, address are so assigned successively that intervals of memory bits of the minor loop will be A+B+C. For example, number (m) of minor loops is set 512, and number (n) of memory bits of minor loops 1 to 1009. Further, numbers of bits from terminal minor loop 1 to generator 7 and detector 8 are so set that α=β=12. Furthermore, gates 2 and 4 are linked to major lines 3 and 5 at every other bit. Thus, adjacent addresses are assigned to memory bits on minor loops at intervals of 2m+α=512×2+12=1036 bits.

Title: Apparatus for generating impulse force
Inventor: KATAOKA FUKUHIKO
IPC: G01M7/08
Filed: 1990-05-11
Abstract: PURPOSE:To securely measure impact force in a short time with a small and simple apparatus by utilizing compressed air pressure to cause a weight to collide against an object and functioning also retracting force at the time of the collision for preventing double punches. CONSTITUTION:At the time of startup, valves 12, 14 of push-out circuits A, B are opened, valves 28, 29 of escaping circuits G, H connected to retracting circuits E, F are opened, and a piston 6 is lowered to have a weight pushed out by a rod 3. At this time pneumatic pressure is directly supplied from a compressed air source 7 to maintain piston pressure constant. Valves 15, 19 are opened immediately before collision to prepare for retracting of the piston 6, and valves 25, 27 are opened to have retracting pressure functioned. The retracting circuits E, F function in parallel with each other at this time to keep working pressure constant. Immediately after the collision the valves 12, 14 are closed so that push-out pressure does not function, and the piston 65 does not punch twice due to back pressure and retreats immediately. After the piston 6 has retreated to some degree, the valves 15, 19 are closed and a valve 16 is opened to limit an exhaust amount. The piston 6 decelerates and returns to a start point. A point of working of a valve is determined based on a time when the piston 6 passes by a detector 5.

Title: Phase adjustment circuit and method for fm broadcast equipment
Inventor: KAWANO AKINORI
IPC: H03F3/68
Filed: 1998-04-30
Abstract: PROBLEM TO BE SOLVED: To provide a phase adjustment circuit capable of automatically adjusting an output power. SOLUTION: A modulator 1 performs frequency modulation on an input signal. A power distributor 2 distributes a supplied FM signal to three paths. Phase converters 3a to 3c adjust phases of the supplied FM signal in accordance with a phase control voltage. Power amplifiers 4 to 4c amplify a power of the supplied FM signal. Directional couplers 5a to 5c supply the amplified FM signal with a power mixer 6 and supply part of it with detectors 7a to 7c. The power mixer 6 mixes the supplied FM signal and outputs it as an output FM signal.  A phase control voltage operation circuit 8 detects a difference in a signal level which each of the detectors 7a to 7c detects, generates the phase control voltage for adjusting the phase so that the difference becomes zero, that is, phases of the output FM signal of the power amplifiers 4a to 4c coincide with one another, and supplies it with the phase converters 3a to 3c.

Title: Scroll type compression machine
Inventor: KIKUCHI KAZUTO
IPC: F04C18/02
Filed: 1989-05-16
Abstract: PURPOSE:To slide both scroll members smoothly and stably by rotatably inserting a drive pin which is provided at one end of a main shaft so that the eccentric distance from a main shaft center of the drive pin can be bigger than both of the eccentric distance from a bush center and the radius in circular orbit movement of an eccentric hole. CONSTITUTION:When a movable scroll member 31 is given fluid compression due to circular orbit movement, corresponding reactive force operates on a scroll element 311, or a member 31, in a contact direction of the circular orbit. This force operates on the center OC of a bush 5a, like FD. As the bush 5a is allowed for free rotation on a drive pin 5b, it is subjected to moment for rotation around the center OD of the pin 5b due to force FO. That is, the member 31 which is supported on the bush 5a is subjected to moment for rotation around the center OD of the pin 5b so that the scroll element 311 is pressed against a scroll element 301. Pressing force at the line-contact portion of both scroll elements 311, 301 is thus automatically gained to ensure the seal of a fluid pocket.
