Title: High frequency combining distributing device
Inventor: SEKINE KENJI
IPC: H01P5/12
Filed: 1984-11-21
Abstract: PURPOSE:To prevent abnormal oscillation or instable operation by providing a band stop filter where the resonance frequency of a resonator is short-circuited on a wall face at least to one side wall forming a short-circuit face of a cavity resonator and providing a radio wave absorbing body to the rear side of said filter. CONSTITUTION:The filters 9, 10 are constituted coaxially while using a metallic wall 8 as an outer conductor and the face of a cavity resonator is nearly short- circuited. In this structure, the gap between the metallic wall 8 and the metals 9, 10 forming the filters is general sufficiently and a notch of 1/4 wavelength is formed in the lengthwise direction to form the 2-stage constitution viewed from the cavity resonator while repeating short-circuit and opening. When the filters are viewed from the cavity resonator, the impedance is close nearly to short-circuit at the center of the band but the transmission region of a radio wave is formed except for the band. Then the reflection at the outside of the band is decreased by providing the radio wave absorbing body 11 to the rear side of the filters. The radio wave absorbing body is formed tapered because the radio wave is absorbed smoothly.

IPC: C04B38/00
Filed: 1989-09-20
Abstract: PURPOSE:To obtain a ceramic porous body having an arbitrary porosity by a simple operation by subjecting lithium aluminate powder to hydration as pretreatment by immersion in water under specified conditions when a porous body based on the powder is produced. CONSTITUTION:Lithium aluminate powder is put in such as amt. of water as to prepare a slurry having 1-20wt.% concn. and the slurry is allowed to stand at 0-100 deg.C for >=10min, freed of the water and dried to obtain dry powder of lithium aluminate hydrate. This powder is molded and sintered to obtain a porous body having an arbitrary porosity. The shape of the lithium aluminate powder is changed from the granular shape to a flaky shape by hydration and the degree of change depends on conditions in hydration. The degree of hydration is changed by controlling the concn. of the powder, the treatment temp. and time and the porosity after molding and sintering is changed according to the degree of hydration.

Title: Method for stabilizing start-up of generator for gaseous rx, gaseous ax and the like
Inventor: AARU JII BOOZU
IPC: B01J7/00
Filed: 1987-09-29
Abstract: PURPOSE:To reduce the start-up time of the title generator by introducing an inert gas for the time sufficient for driving out the residual gas after the shutdown of the generator, and further introducing the inert gas at a low flow rate at the time of cooling, nonuse, and reheating of the generator. CONSTITUTION:After the generator for gaseous RX, gaseous AX, etc., using a catalytic metal is stopped, an inert gas is introduced at a high flow rate for the time sufficient for driving out the residual gas in the generator, and the gas is preferably introduced by the volume 3-10 times the content volume of the generator. The inert gas is successively introduced at a low flow rate by the volume 0.3-2.5 times the content volume of the generator at the time of the cooling, nonuse, and reheating of the generator. As a result, since the inside of the generator is filled with the inert gas before start-up, seasoning is not required, and the need for no-load running by gaseous RX is eliminated.

IPC: B21C9/00
Filed: 1987-09-28
Abstract: PURPOSE:To prevent a pipe from being ruptured and to continuously form a thin pipe by providing a through-hole on at least one of plugs so that oil which has filled the pipe can flow through. CONSTITUTION:In case of executing a pipe drawing processing, oil is injected in advance into a pipe 10. The oil adheres to an inner wall of the pipe 10, and moves in the right direction by a small quantity each together with the pipe 10. That is, the oil which has passed through between a plug 20a and a pipe 10a passes through between a plug 20b and a pipe 10b in the next time. The further it advances, the higher a passing speed of the pipe 10 becomes, therefore, the quantity of oil which adheres to the pipe 10 and passes through becomes small. In plugs 20b, 20c, through-holes 24b, 24c are formed, the pipes 10b, 10c pass through the through-holes 24b, 24c and oil and air flow into the pipes 10c, 10d. The tip of the pipe 10d is closed up tightly, therefore, it does not occur that pressure in the pipes 10b, 10c becomes high, and the pipes 10b, 10c are ruptured.

Title: Convolutional arithmetic processor
Inventor: MAENO TAKAHIRO
IPC: G06F17/10
Filed: 1986-10-16
Abstract: PURPOSE:To increase the convolutional arithmetic processing speed with no increase of the circuit scale by using a data memory to hold the signal data, sharing a single arithmetic unit for both addition and multiplication carried out at each delay stage and using a virtual address to perform the delay processing to simply obtain a physical address from the virtual address. CONSTITUTION:An address generator 50 produces successively the physical addresses Xb-(Xb+n) to a data memory 24 by the output of a microprogram controller 22 and then the physical addresses corresponding to virtual addresses 0-n to a signal data memory 23. Then the accesses are given to both memories 23 and 24. An arithmetic unit 21 uses a single coefficient data and a single signal data obtained a single access respectively to carry out a single multiplying operation and a single accumulating operation. A single convolutional arithmetic operation is finished by repeating the multiplication and accumulation by (n+1) times for production of a single convolutional arithmetic processing data. Thus a single signal processing cycle is through. Both multiplication and addition are carried out by the unit 21 at each delay stage and the delay processing is carried out by means of a virtual address and with no shift of the contents of the memory 23. Thus it is possible to perform a convolutional arithmetic processing of a large scale at a high speed and with high accuracy without increasing the circuit scale.
