Title: Treatment of lead sulfate-containing material
Inventor: SUGANUMA TOSHIO
IPC: C22B13/02
Filed: 1996-03-11
Abstract: PROBLEM TO BE SOLVED: To provide a treatment method for a lead sulfate-contg. material having excellent treatment efficiency. SOLUTION: A carbon source is added to the lead sulfate-contg. material and the material is put into a sintering furnace. The inside of the furnace is maintained by using a carbon source as a heat source at a high temp. at which the lead sulfate decomposes. While the formation of lead sulfide and metal lead is suppressed, the conversion from the lead sulfide to lead oxide is accelerated in the presence of carbon monoxide generated from the carbon source. The sintered compact formed in such a manner is crushed and is then subjected to smelting reduction in a blade furnace, by which the lead metal is recovered.

Title: Manufacture of lateral transistor
Inventor: HORIE NOBORU
IPC: H01L29/72
Filed: 1981-04-10
Abstract: PURPOSE:To highten hFE and cut-off frequency fT without decreasing dielectric strength, by providing a first hole in a protection film of an N layer, introducing an impurity to form a base layer having a concentration gradient, and providing P type emitter and collector layers through a second hole apart from the first hole. CONSTITUTION:An N epitaxial layer 3 is provided on a P<-> type Si substrate 1 having an N<+> buried layer 2, and separated by a P<+> layer. An N layer is formed by diffusing P or the like from a window of the SiO2 9 emitter part. A horizontal concentration gradient is formed by means of a base layer between an emitter layer 7 and a collector layer 6 so that the emitter side is of higher concentration. A P<+> emitter 7 and a P<+> annular collector 6 are formed simultaneously. An N<+> connecting layer is provided, and an Al electrode 10 is attached. A dotted line 11 shows a boundary between the N epitaxial layer 3 and the high-concentration layer. Providing such a concentration gradient permits a cut-off frequency to be four to five times higher. In addition, no positioning error occurs, and hFE and fT are equalized because the base layer 5 and the emitter layer 7 are formed from the same hole.

Title: Angular velocity detector
Inventor: SAWADA SHIGETOMO
IPC: G01C19/58
Filed: 1988-03-09
Abstract: PURPOSE:To simplify the structure of the title detector and, at the same time, to reduce the weight and price of the detector by measuring the change in the propagating time of the electric signal impressed upon superconductive coils from one end to the other end of the coils in accordance with the peripheral speed of the above-mentioned superconductive coils when the coils are rotated around their axes. CONSTITUTION:Superconductive coils 102 are arranged in the vertical direction on the same axis. Each oil 102 is rotated in the same direction at a peripheral speed V and electric signals are impressed upon an input terminal 2 from a pulse generator 5. In this case, the relation between the flowing direction of the signal current and the rotating direction of each coil 102 becomes opposite. Therefore, the difference between the times required by the electric signals to reach an output terminal 3 and to reach another output terminal 4 is proportional to the total length of the superconductive coils 102 and the peripheral speed V and measured by an interval measuring instrument 6. Then the angular speed of the coils 102 is calculated from the difference by means of an angular speed computing element 7. Thereafter, the azimuth theta at the current moment is calculated by means of an azimuth computing element 8.

Title: Computer system
Inventor: NONAKA JUICHI
IPC: G06F11/00
Filed: 1988-03-09
Abstract: PURPOSE:To prevent the destruction of data in a memory and the loss of data at the time of initialization by prohibiting the memory write of a CPU at the time of detecting runaway and executing a processing with data in the memory is protected as it is at the time of reset. CONSTITUTION:When a runaway supervisory circuit 6 detects the runaway of the CPU1 in the middle of operation, a detection signal H is detected and a NAND gate 5 prohibits the passage of an active memory write signal L from a bus controller 4. At the same time, the active signal is given to a mask impossible interruption terminal NMI in the CPU1, and the CPU 1 which has received it, stops. Since an LED19 lights by the output signal of the circuit 6, an operator who has detected runaway turns off a switch 17 and gives a reset command to the CPU1. Thus, the CPU 1 starts an initial operation program and starts the processing. At that time, a rise mode circuit 16 is collated, and maintenance data comes to zero and shows a maintenance mode. Thus, the CPU1 protects the memory 7.

Title: Anti-skid controller
Inventor: MATSUDA TOSHIROU
IPC: B60T8/70
Filed: 1980-04-25
Abstract: PURPOSE: To prevent the setting of a wrong braking target even if speed of a wheel irreugularly changes, by setting a new linear braking target only when the speed of the wheel is within a certain region.  
     CONSTITUTION: Speed of a wheel 1 is converted into a voltage signal by an f/V converter 3, and decelerated speed αw is detected by a differentiator 4. A comparator 5 outputs a signal e b1  when the wheel decelerated speed αw exceeds a prescribed value αb. An output signal v wo  of a linear target generator circuit 6 is decreased a prescribed amount by a reference value generator circuit 7 to a reference value v s , and a signal e b2  is output from a comparator 8 when exceeding the wheel speed. An AND gate 9 is operated by AND of the signals e b1  and e b2  to actuate the linear target generator circuit 6. Since the linear target generator circuit 6 opeates only when within a region of prescribed amount from the linear target, the setting of wrong linear target due to the bounding action of a wheel can be prevented.

The spit holder 6 is moved along a guide rail 11 and the spit 16 is set in a state that the food is directed downward. Further, when the spit 16 is moved, the spit is crimped by a chuck 4 for delivery. When a chuck 2 for reception on the side of an automatic spit-roasting machine 1 is positioned by an arm 3, the chuck 4 for delivery falls down and pulls off the spit 16 from the holder 6. Then, the spit 16 is fitted into the positioned and stopped chuck 2 for reception.
