Title: Production of charcoal
Inventor: HIMEDA MASATAKA
IPC: C01B31/00
Filed: 1989-03-01
Abstract: PURPOSE:To obtain charcoal having high strength in a high yield by embedding wood in coal powder and carrying out dry distillation. CONSTITUTION:Wood of a needle-leaf tree (e.g. a Japanese cypress obtd. by thinning), etc., is mixed with coal powder such as blended coal for producing coke for metallurgy so that the wood is embedded in the coal powder. The resulting packed bed is packed into a vessel with the top open, this vessel is charged into an electric furnace having a function for exhausting gas generated during dry distillation and dry distillation is carried out at about 900 deg.C. Gas generated during this dry distillation is burned and released through a duct. After dry distillation is finished, the vessel is taken out of the furnace, digesting is carried out by sprinkling water and produced charcoal is collected by separating and removing produced coke.

Title: Chuck, jaw and wedge plunger for operating jaw
Inventor: TOYANO HIDEKATSU
IPC: B23B31/177
Filed: 1998-02-13
Abstract: PROBLEM TO BE SOLVED: To prevent deformation and breakage of an overhang portion of a wedge plunger, and reduce machining time of a wedge operating portion. SOLUTION: A wedge 18 of a jaw 10 is arranged on one side of a reinforcing longitudinal member 17. A wedge groove 35 of a wedge plunger 30 has a complementary form provided with an overhang member 36 receiving the wedge 18. The least number of tapered surfaces 19, 20, 37, 38 are thus formed by the wedge 18 and the wedge groove 35, which surfaces generate wedge function through mashing. It is therefore possible to reduce machining time, facilitate machining and improve cost. Outer deformation of the overhang portion 36 is supported by a receiving surface 45, so that breakage of the overhang portion 36 is prevented.

Filed: 1981-03-31
Abstract: PURPOSE:To achieve high speed reproduction without noise bar, by replacing the lowering in a reproduced output signal of a main rotating head caused during high speed reproduction with a reproduced output of an auxiliary rotating head. CONSTITUTION:A pulse signal per one revolution of a rotating disc 3 obtained at a detection head 14 is delayed at a signal processing section 20, and converted into a pulse signal which is at H level in the timing when a main rotary head M1 scans the start point of a track and at L level in the timing when a main rotary head M2 scans the start point of the track. When this signal is at H level, the output signal of the main rotary heads M1 and M2 is picked up, and when at L level, the output signal of auxiliary rotary heads S1 and S2 is picked up. As a result, a constant double speed reproducing video signal without noise bar at the output of a video signal demodulating circuit is obtained.

Title: High efficiency vacuum ultraviolet light source device
Inventor: SUZUKI SETSUO
IPC: F21K99/00
Filed: 1989-03-03
Abstract: PURPOSE:To obtain the vacuum ultraviolet light having the high discharge efficiency by performing a pulse discharge with a mesial magnitude width of a current pulse less than 1 micro second and with an interval of a current pulse more than 30 micro seconds. CONSTITUTION:A pulse discharge is performed between opposite electrodes of a discharge tube to generate the vacuum ultraviolet light from the discharge plasma. Since a mesial magnitude width of a discharge current pulse is a short time less than 1 micro second, the glow discharge is finished and stopped without a conversion to the arc discharge with large power consumption. Since a pulse interval is a long time more than 30 micro seconds, the plasma impedance becomes large enough till a start of a discharge. With these reason, the pulse current rises quickly, and further, a current peak value is large to obtain the high vacuum ultraviolet light with the high discharge efficiency. The sealing gas of the discharge tube is specified and that gas is flowed to eliminate the generation of the impure gas and the lower of the luminescent intensity.
