Title: Carbonization of coal
Inventor: ARAMAKI TOSHIHIRO
IPC: C10B47/10
Filed: 1988-10-15
Abstract: PURPOSE:To promote drying of uncarbonized part, to increase heating rate of coal pillar and to shorten time required for carbonization, by efficiently discharging steam evolved from uncarbonized part of coal pillar out of the system during carbonization. CONSTITUTION:Before carbonization operation is carried out, a passageway 11 connecting uncarbonized part surrounded by a plastic layer 10 to the outside of coal pillar is formed in a charged coal pillar 7 and carbonization is effected while discharging gases (mainly comprising steam partially containing vapor of low-boiling tar) evolved from the uncarbonized part through the passageway 11. A hollow pie gas conduit 12 inserted into the coal pillar so as to connect the inside of the coal pillar to the outside is preferable as a means to form the passageway 11.

Title: METHOD FOR HOT WORKING S-ADDED Fe-Ni ALLOY
Inventor: WATANABE JUN
IPC: C22C38/08
Filed: 1999-09-13
Abstract: PROBLEM TO BE SOLVED: To prevent deterioration in hot workability, particularly edge cracking, etc., at hot rolling, by heating an Fe-Ni alloy slab, having a specific composition consisting of Ni, Mn, S and the balance Fe with inevitable impurities, under specific conditions, successively heating at higher temperature, and then hot working. SOLUTION: An Fe-Ni alloy slab, having a composition consisting of, by weight, 30-55% Ni, 0.10-1.00% Mn, 0.0005-0.030% S and the balance Fe with inevitable impurities, is heated to 850-1150 deg.C for >=30 min, successively heated to >1150-1300 deg.C for <=1 h, and hot worked. As a heating furnace for performing the above two-stage heating, a nonoxidizing furnace is preferred from the viewpoint of preventing deterioration in hot workability due to intergrannular oxidation, etc., and deterioration in yield due to oxidation. Further, it is preferable to regulate the rate of temperature elevation to >=3 deg.C/min at the transition from the first-stage heating to the second-stage heating.

Title: Cap closing mechanism for carbonated drink bottle
Inventor: KOBA TOSHIMITSU
IPC: B65D39/08
Filed: 1994-09-28
Abstract: PURPOSE: To maintain stable cap opening for a long period of time by equalizing the vertical pitch of horizontal extension end threads located at the bottom of multiple male thread ridges to the vertical sectional length of the multiple male thread ridges. CONSTITUTION: When a cap 1 is turned to be opened in a direction, in which both threads 10 and 15 are loosened, by holding an outer shell 7, an inner plug 6 turns integrally with the outer shell 7, because a projection 14 becomes engaged with a cut 8. Being made of a hard synthetic resin, the outer shell 7 cannot be distorted by a grasping power for turning it. When the inner plug 6 turns, the multiple female threads 10 and male threads 15, the ridges 10a, 15a of which are pressed to each other, start engaging securely, because the vertical pitch (W) of the ridge 15a on the horizontal extension 15b of multiple threads 15 is equal to the vertical sectional length (W) of the ridge 10a of the female thread 10. When the inner plug 6 is turned further, the threads 10 and 15 are released from engagement to raise and remove the plug body 1 from the bottle mouth 2.  This mechanism ensures safety, because it prevents the plug body 1 from being sprung out by gas pressure unexpectedly during cap removing.

Title: Reflex type discharge lamp and illumination device
Inventor: TAKITA KAZUO
IPC: H01J61/88
Filed: 1992-09-29
Abstract: PURPOSE:To provide an illumination device ensuring good practical application, which admits being combined with a simple power supply device and can prevent alkali metal from going out even in the case a metal vapor discharge lamp with alkali metal therein is accommodated in a reflective vessel. CONSTITUTION:At least mercury, halide of alkali metal, and tin halide are encapsulated in a metal vapor discharge lamp 2 which is installed in a reflective vessel 1, and a power supply device for lighting up the discharge lamp 2 is furnished. Because the energy to energize the mercury which is encapsulated as a buffer metal, is consumed in energization of the tin halide, ultraviolet emission of the lamp is reduced to a great extent, and generation of photo- electrons which draw alkali metal is decreased, and the alkali metal is prevented from going out. As the electric characteristics of the metal vapor discharge lamp are stabilized, it can be lighted up by a power supply device which presents a simplified degree of tolerance for variation of the electric characteristics.

Title: Bus control system
Inventor: HIROTA YASUO
IPC: G06F13/362
Filed: 1990-09-28
Abstract: PURPOSE:To control arbitration at a high speed by permitting bus masters participating in arbitration to occupy a bus in order from the most preferential bus master by a priority level determining means. CONSTITUTION:Bus masters 21-1,...21-n output the bus request signals when they use the bus. If they output the request signals at the time of receiving a bus permission signal from an arbiter 22, they participate in arbitration by judgement of bus arbitration participation deciding means 23b,...25b; but otherwise, they do not participate in arbitration by these means. Bus masters 21-1,...21-n which participate in arbitration compare contents of priority level holding means 23a,...25a with a signal on the bus by priority level determining means 23d,...25d, and the bus master having the highest priority level outputs a bus busy signal to terminate arbitration of the other bus masters and occupies the bus to access a connected device, and the other bus masters waits for termination of bus occupation due to bus masters having higher priority levels. Thus, the control is performed at a high speed.

Title: Apparatus for detecting tracking error
Inventor: MARUOKA TOMOHIKO
IPC: G11B15/467
Filed: 1994-10-25
Abstract: PURPOSE: To efficiently detect a pilot signal in a small-size circuit by recording two pilot signals to alternate tracks and scanning one track by two heads each having an overlap area when data are reproduced. CONSTITUTION: Reproducing signals including pilot signals f1 , f2 from heads 21, 22 are turned to signals (g), (h) via filters 301, 302. The signals are inputted alternately to a detection circuit 313 via an A/D converter 304 with a sampling frequency through a switch 303 controlled by an exclusive OR circuit 305. The amplitude of each signal f1 , f2 is detected in a time division multiplexing method and signals proportional to the respective amplitudes are alternately output. The output signal is delayed at a delay 413 and a difference from the original signal is obtained at a subtracter 411. Only a desired signal is outputted from a latch 412 to obtain a tracking error signal.  Since the shifting direction by a track scanned by the head 21, 22 and the polarity of the output of the latch 412 are different, the code is reversed according to the track at a polarity inverter 601 and finally the tracking error signal is outputted.
