Title: Method and apparatus for magnifying picture
Inventor: OKADA YOSHIYUKI
IPC: H04N1/393
Filed: 1988-04-07
Abstract: PURPOSE:To obtain a conversion picture having hatched line smoothed naturally at a high speed by setting a border line in matching with the slope of hatched lines affected largely by the shape of the border line. CONSTITUTION:A picture element group to be converted belonging in the vicinity of the conversion picture element by projection is inputted to a picture element input means 11 to be converted sequentially with respect to a prescribed conversion picture element and a hatched line pattern detecting logic circuit 12 by a command from a control section 13 to take correspondence with a hatched line pattern and the result is sent to the control section 13 by a 7-bit signal. The control section 13 uses the border line decided based on the signal and the conversion magnification. Thus, even when the angle of the hatched line pattern in the picture to be converted is other than 45 deg., the smoothing of hatched lines is not made unnatural.

Title: Release of choke of downward pipe line
Inventor: OKAYAMA KYOJI
IPC: B65G53/30
Filed: 1989-04-04
Abstract: PURPOSE:To release easily choke in a downward pipe line for hydraulic transportation of coal or the like by sending only liquid having pressure higher than that in the pipe from an outlet to form a liquid path in a choked portion and then sending liquid from an inlet while pressures in the outlet and inlet are balanced with each other and the pressure is graduately increased. CONSTITUTION:When choke takes place by power failure or the like, apparatuses are stopped, a water forcing machine 21 and regulating device 23 are started, water is pressurized to a value shown by a pressure gauge 16 and a switch valve 25 is opened to send water into a pipe 2. In the absence of abnormal conditions in instruments the pressure is somewhat increased and maintained to run the apparatus for a certain time. When a flow meter 18 shows flow proportional to the pressure increase and proves that the water does not reach the choked portions, the pressure is increased and water is further forcible supplied. When the flow corresponding to the pressure increase is lost and the abrupt pressure increase is shown, the pressure is returned to the initial one prior to the abrupt pressure increased to run the apparatuses for a certain time and again increase the pressure. This operation is repeated. Thus the choke can be easily released.

Title: Signal separating circuit of television receiver
Inventor: MURATA TOSHINORI
IPC: H04N9/78
Filed: 1986-04-14
Abstract: PURPOSE:To prevent ringing from being caused and to prevent picture quality from deteriorating by inserting a comb-line filter which uses a line memory into a luminance signal processing system and controlling it properly through a switch. CONSTITUTION:A frame memory 9, subtracters 3 and 5, a band-pass filter 4, and a 1/2 attenuator 8 constitute a comb-line filter 23; and 1/2 attenuator 8 outputs a chrominance signal and the subtracter 5 outputs a luminance signal. Namely, the chrominance signal and luminance signal are separated completely by the comb-line filter 23. Then, the output of the subtracter 5 is inputted to the comb-line filter 24 composed of a line memory 10, a subtracter 12, a band- pass filter 15, a subtracter 16, and a 1/2 attenuator 14. In this line memory type comb-line filter 24, a signal which is inverted in polarity among scanning lines and has a high frequency component appears at the output of the band-pass filter 24, so this is subtracted from the original luminance signal by the subtract er 16 to obtain a luminance signal from which a slanting high frequency compo nent is removed.

Title: Device for growing thin diamond film
Inventor: SAKURAI MICHIO
IPC: C30B29/04
Filed: 1988-04-06
Abstract: PURPOSE:To produce a thin diamond film having uniform quality with good reproducibility with the device for growing the thin diamond film by a heat filament vapor growth method by using a rhenium filament which is not carbonized as the filament. CONSTITUTION:A high-frequency heating furnace 1 is disposed to the outside circumference of a quartz tube 2 and a substrate holder 5 is installed in the tube 2. The rhenium filament 3 is installed above the substrate holder. A substrate 4 is imposed on the holder 5 and while a gaseous raw material (e.g.: gaseous mixture of methane and hydrogen) is introduced into the quartz tube 2, the filament 3 is heated further to a high temp. by heating in the furnace 1 to excite the gaseous raw material and to grow the thin diamond film on the substrate 4. Since the carbonization of the rhenium filament 3 is thereby obviated, the temp. control with good accuracy and the control of the current density for releasing thermions are enabled. The thin diamond film having the uniform quality is thus produced.

Title: Fault detecting device for radiation detector
Inventor: MATOBA TAMOTSU
IPC: G01T1/18
Filed: 1979-07-02
Abstract: PURPOSE: To enable the fault detection for the radiation detector even in case the ordinary radiation level is less than the minimum detection sensitivity, by securing the leak of the checking radiation of the radiation source at all times via the movable shutter or the like.  
     CONSTITUTION: The checking radiation sent from checking radiation source 4 of screw lever 5 screwed into attachment plate 6 leaks out at all times through shutter 2, and is then set to the value less than the minimum detection sensitivity through the selection of the distance between source 4 and Geiger-Muller counter tube (GM tube) 1 caused by lever 5, the thickness of shutter 2 and other factors to be applied to GM tube 5. When shutter 2 is opened via solenoid 3, the checking radiation of source 4 is applied directly to the GM tube. Thus the fault detection of the GM tube vecomes possible even in case the ordinary radiation level is less than the minimum detection sensitivity by the indication of several times as much as the minimum detection sensitivity. The same effect can be secured if some inclination is given to the thickness of the shutter with the radiation source fixed.

IPC: H04B10/275
Filed: 1992-04-07
Abstract: PURPOSE:To apply a large capacity transmission line efficiently through multiplexing by adopting a network of a ring structure at a level of a path group and sending/receiving a control signal integrated in a path overhead for each ring between two points having a changeover switch so as to changeover the path groups. CONSTITUTION:Each section described below being a component of each node in a transmission network using an SDH selects a path level by easy control equal to that of a section level. That is, each of transmission line reception sections 3-1-3-4 terminates an SDH signal received from each of transmission lines 1-1-1-4 and gives the signal to a path connection section 9 in the unit of VC-3/4 and detects path group overhead information. Based on this information, a changeover control section 12 discriminates the selection of the path group and controls the control section 9 to select a path group and transmission line transmission sections 4-1-4-4 multiplex the VC-3/4 from the connection section 9 and send the resulting SDH signal to transmission lines 2-1-2-4. Thus, a large capacity transmission line is efficiently applied.
