Title: Sluice valve for coal/petroleum mixed fuel
Inventor: KATSURA TOKUJIRO
IPC: F16K3/12
Filed: 1988-10-17
Abstract: PURPOSE:To prevent the blocking of complete sealing due to the accumulation and consolidation of the solid component of the mixed fuel in the pocket section of a valve by forming comb teeth-shaped grooves on the pocket section at the lower section of a valve box and the outlet side at the lower section of a passage so as to be communicated to the outlet side of the valve box. CONSTITUTION:The solid component in the coal/petroleum mixed fuel (COM) flowing down in a sluice valve is sunk and stuck in a pocket section 5 and comb teeth-shaped grooves 9. The flow area at a valve body 4 is reduced by the closing operation, the flow speed in the sluice valve is increased, and the solid component sunk and stuck there flows away to the outlet side. The solid component not flowing out at the flow speed of the COM is pushed by the descent of the valve body 4 and extruded to the outlet side through the comb teeth-shaped grooves 9. The solid component of the COM is prevented from being stuck on the set face of a valve seat 3 and consolidated in the pocket section 5. The valve is completely closed, and the leakage at the outlet side is prevented.

Title: Method of winding up yarn in pirn winder
Inventor: YAMAMOTO SHIGERU
IPC: B65H54/28
Filed: 1990-09-28
Abstract: PURPOSE:To make the degree of wind-up on a bobbin uniform during each doffing step so as to eliminate a difference in length of yarn between doffing steps, by initiating the movement of a ring from a traverse position to the top end part of the bobbin before completion of counting so as to make the position of the ring upon completion of the counting coincident with an arbitrary position on the top end part of the bobbin. CONSTITUTION:While a ring is moved along a bobbin so as to wind up a yarn fed from a supply roller onto a pirn shape package, the management of the length of a normal yarn which is wound up onto a bobbin is carried out by counting a number of revolutions of the supply roller, and the counting is initiated at the time point when the ring has been shifted to an arbitrary position on the bobbin from a west spool. The shift of the ring from a steady-state traverse position to the top end part of the bobbin is initiated before completion of the counting so that the position of the ring upon completion of the counting is set to be coincident with an arbitrary position on the top end part of the bobbin.

Title: Internal clock generator in picture processor
Inventor: SHIRAE TAKASHI
IPC: H04N19/00
Filed: 1985-11-21
Abstract: PURPOSE:To use a PLL inferior in response by forming a signal in such a manner that a synchronizing signal in a vertical synchronizing signal part of the synchronizing signals taken out from a video composite signal has the same cycle as a horizontal synchronizing signal, and using the result for the PLL. CONSTITUTION:The synchronizing signal is separated from the video composite signal A in a synchronization separating circuit 20, a pulse signal B is outputted during a rise time of the synchronizing signal by a monostable multivibrator 21 and supplied to one input of an AND circuit 22. When a signal from an inverter 24 is supplied to the other input, a monostable multivibrator 23 outputs a pulse signal D with a prescribed duration. Since this pulse signal D is inverted in the inverter 24 and inputted to the AND circuit 22, the AND circuit 22 cannot operate during outputting the pulse signal D and checks the signal B. Namely, the vertical synchronizing part of the video composite signal A has equalizing pulses checked ever other interval by the pulse signal D and the cycle of a pulse signal C from the AND circuit 22 is equal and the same as the cycle of the horizontal synchronizing signal.

Title: Auxiliary air supplier for internal combustion engine
Inventor: KOKETSU MIKIYASU
IPC: F02D33/00
Filed: 1987-10-19
Abstract: PURPOSE:To enable an auxiliary air quantity to be limited even a power supply fails by making it possible to radiate heat also from the engine block side on the thermally reactive member of an auxiliary air supplier. CONSTITUTION:When the temperature of an engine block 31 rises, the heat on the engine block 31 is transmitted from a connected leg part 29 to a stay 28 and transmitted to a thermally reaction type cylinder 11 through the circumference of a housing main body 7. Therefore, since heating of PTC element 15 and transmissive heat of the engine block 31 are radiated to the thermally reactive type cylinder 11 in the state after finishing a warm up run, a valve body 22 fully closes a valve hole 10, thereby a bypass route is shut off to stop supply of the auxiliary air. Accordingly, the thermally reactive cylinder 11 can receive heat from the engine block 31 to prevent the valve body 22 from being separated from the valve hole 10 even though the PTC element 15 stops its heating. Therefore, abnormal rise of the engine speed can be prevented because no auxiliary air is supplied to the engine 1.

Title: Method and apparatus for molding
Inventor: SOBA TAKUMI
IPC: B29L31/34
Filed: 1993-09-24
Abstract: PURPOSE:To reduce the quantity of resin to be used in a resin sealed package. CONSTITUTION:In a transfer molding apparatus 20, a slider 31 is laid on a runner 27 such that the slider 31 can advance or retracts in the direction for increasing or decreasing the cross-sectional area of channel in the runner. After a resin 42 in a pot 24 is substantially pushed out, the slider 31 is advanced to constrict the channel of the runner 27. Consequently, the quantity of resin 42 being left finally in the pot 24 and the main runner 27 is minimized and thereby useless consumption of the resin 42 can be minimized. Since the runner 27 has a predetermined cross-sectional area of channel, the cavity 23 can be filled correctly with the resin 42. Since each cavity can be additionally fed with the resin 42 and the fully filled resin is compacted, the resin sealed package can be molded correctly.
