Title: Paper feed mechanism of printer
Inventor: NANBA HIDEYUKI
IPC: B41J11/02
Filed: 1987-03-10
Abstract: PURPOSE:To perform uniform paper feed, by negating the variation in feed quantity generated by the eccentricity possessed by a platen itself by the action of a belt route changing means. CONSTITUTION:In adjusting the quantity of eccentricity of an eccentric roller 22, a screw 26 is loosened and an adjust screw 25 is rotated by predetermined quantity in a predetermined direction. The support gear 23 of the eccentric roller 22 is driven by the gear 27 on the same shaft as a platen 11 through an idle gear 28 to rotate in the same direction as the platen 11 but, since the number of teeth of the gear 23 is the same to that of the gear 27, the eccentric roller 22 performs eccentric motion at the same cycle as the rotary cycle of the platen 11 to change the route of a belt 16 on a tension side and the rotational speed of a platen shaft 29 cyclically generates delay and advance. Then, by adjusting the quantity of eccentricity and phase of the eccentric roller 22, the variation in the feed quantity generated by the eccentricity possessed by the platen itself is negated and uniform paper feed is realized.

Inventor: KAMETANI TETSUJI
IPC: C07H13/06
Filed: 1987-03-10
Abstract: PURPOSE:To readily and selectively synthesize the titled compound in a short step and promote mass-production thereof, by subjecting a specific cyclopentane derivative used as a raw material to specific chemical treatment. CONSTITUTION:A cyclopentane derivative expressed by formula I (X is ketone- protecting group; R<1> and R<2> are amino-protecting group; R<3> is carbonyl- protecting group) is initially used as a raw material to convert the group -CO2R<3> of the above-mentioned derivative having a desired steric configuration into -OH group. The ketone-protecting group (X) of the resultant compound expressed by formula II is then removed to provide a compound expressed by formula III, which is then subjected to the Baeyer-Villiger oxidation to afford a lactone expressed by formula IV. The carbonyl group of the afore-mentioned compound is finally reduced to provide the aimed compound expressed by formula V. Furthermore, the conversion of the above-mentioned group -CO2R<3> into the -OH is preferably carried out by hydrolyzing the compound expressed by formula I, alkylating the hydrolyzed compound with an alkylating agent expressed by the formula R<4>Li (R<4> is alkyl), then subjecting the formed ketone derivative to the Baeyer-Villiger oxidation and hydrolyzing the resultant compound.

Title: Tape running device
Inventor: KAWAKAMI HIROSHI
IPC: G11B15/60
Filed: 1982-03-31
Abstract: PURPOSE:To absorb the oscillation of a tape, by making the mass of a clipping member, which is rotated while being brought into contact with a magnetic tape considerably larger than that of the magnetic tape, and utilizing the position of clipping member as the node of longitudinal oscillation. CONSTITUTION:When a recording or reproducing operation member is operated, an erasing head 7 is inserted to the third window and is brought into contact with a rubber coating 32 of a clipping member 25 through a magnetic tape 15. Since the clipping member 25 is connected frictionally to the magnetic tape 15 by this contacting of the erasing head 7, the clipping member 25 is rotated by run of the magnetic tape 15. When the clipping member 25 starts rotating, it is rotated with a large force of inertia by the action of a flywheel 31, and the clipping member 25 clips the magnetic tape 15 together with the erasing head 7 and holds the magnetic tape 15 smoothly without damaging the run of the magnetic tape. Further, since the rubber coating 32 is brought into contact with the magnetic tape 15, the tape is run while the transverse oscillation and the longitudinal oscillation of the running tape 15 are restrained effectively.

Title: Crystal growth method for inp layer on gaas substrate
Inventor: KIMURA TATSUYA
IPC: H01L21/205
Filed: 1990-03-05
Abstract: PURPOSE:To prevent transposition from propagating to the upper InP crystal layer, and to reduce the number of transposition in the InP crystal layer by a method wherein the transposition in the InP crystal layer is integrated by applying thermal stress on the InP crystal layer by conducting heat cycle annealing, and the transposition is bent in lateral direction using an ultrathin film layer. CONSTITUTION:Heat cycle annealing is conducted in such a manner that a GaAs substrate 1, containing InP layers, is heated up to about 700 deg.C for approximately 10 minutes in a PH3 atmosphere, and then it is cooled down to about 200 deg.C. The above-mentioned treatment is a cycle, and the treatment is repeated several cycles. When the heat cycle annealing is finished, an InP second layer 4 of about 0.1mum in thickness is exitaxially grown under the same condition as the formation of the InP first layer 3. Then, an ultrathin film layer 5, which is called a strained superlattice layer, of In0.9Ga0.1P/about 10nm in thickness formed by one cycle is 5-cycle crystal-grown, for example, on the InP second layer 4 at about 600 deg.C. By providing this In0.9Ga0.1P/InP ultrathin layer 5, transposition is bent in lateral direction, and the upward propagation of the transposition can be prevented.

Title: Control method of conglomerate discharge equipment in shaft furnace
Inventor: YOSHIDA TAKESHI
IPC: C21B13/02
Filed: 1989-03-07
Abstract: PURPOSE:To reduce the frequency of the stoppage of a furnace and clogged material removal work by a method wherein operation is not immediately stopped even when the working hydraulic pressure rises due to clogging of a large conglomerate, etc., before a discharge member reaches the stroke end, and the discharge member is repeatedly reversed an allowable number of times, which is optionally set, to continue the operation. CONSTITUTION:When a discharge apparatus is started and an abnormal 'High' signal of the working hydraulic pressure is not issued, a discharge member 1 moves up to the stroke end, and normal and reverse rotation repeatedly takes place according to stroke end signals to discharge conglomerates. When abnormal 'High' signals of the working hydraulic pressure are issued before the discharge member 1 reaches the stroke end, the discharge member is not immediately stopped but reversed to continue the reciprocating motion, and the member of times of the abnormal 'High' signals or working hydraulic pressure are counted. If the abnormal 'High' signals of the working hydraulic pressure is continuously issued further, the number of times of continuous issue is counted in addition to the previously counted number of times of abnormal 'High' signals. The counted number of times is compared with pre-set allowable number of times (P) of continuously issued abnormal 'High' signals of working hydraulic pressure. When the counted number of times is less than (P), the discharge member is reversed to continue the reciprocating motion, and when it is larger than (P), an alarm is set off and the discharge member is stopped.

IPC: H01J61/067
Filed: 1986-03-14
Abstract: PURPOSE:To obtain a discharge lamp which can suppress the blacking of the tube end and has a definite lighting life time by forming the electrode filament in short length and specifying the distance between the electrode and the glass tube. CONSTITUTION:The relation of the outside diameter L of the tube and the distance l between the electrode 2 and the tube wall to the generation rate of the blacking of the tube end after 2,000hr of the lighting test defined in JIS is shown in the figure, and when the length l becomes shorter than 7mm the generation rate increases steeply. In order to enlarge the distance l between the electrode 2 and the tube wall it is necessary to shorten the length of the electrode filament. Therefore the design of the filament is improved and the filling procedure of an electron emitting material to the filament is improved. When the electron emitting material is coated not only on the primary winding 3 but also on the secondary winding portion 4 of the double coiled filament the coated region l2 of the electron emitting material can be shortened so that the distance l between the electrode and the tube wall can be enlarged.
