Title: Row of continuous casting and rolling installation
Inventor: MASUI TAKESHI
IPC: B21B1/46
Filed: 1983-11-21
Abstract: PURPOSE:To obtain a titled row of installations capable of improving product quality by exposing central segregations to the air and improving its efficiency by rolling a billet into various dimensions by a small-scale facility, by plurally- dividing rolling continuously-cast billets through a heat insulating furnace and coilers and rolling the billets into plates or sheet coils through the furnace. CONSTITUTION:A row of continuous casting and plurally divided rolling installations is joined to the row 57 of finishing mills of a continuous rolling installation, formed by roughing mills 62, at the front of the row 57. Cast billets discharged from continuous casting installations 1, 3 are formed into the cast billets 17, 18 having exposed central segregations in their surfaces, by plurally divided rolling mills 35 (11-16) through a heat insulating furnance, and are wound up by coilers in the furnace 44 through flying shears 38, 39. The coils are straightly charged to the continuous finishing mills 57 from uncoilers 54, 55, or are charged from the uncoilers after keeping them in a heat preserving furnace 53 when occasion demands. Thus the product quality is improved with easy care, because of the coming up of the central segregation part to the surface, and the cast billets are rolled into plates or strips having various dimensions by a small- scale facility.

Title: Information recording and reading device
Inventor: RUDORUFU ROTO
IPC: G11B20/12
Filed: 1990-08-22
Abstract: PURPOSE: To allow an error signal to be corrected by correcting error based on a relative redundancy in information and partially disconnecting information pattern recorded in a selected track part for a suppression in an uncorrectable case. CONSTITUTION: An information pattern corresponding to encoded signal Vk is formed on a WORM type writable recording medium 4. This recorded information is read by a reading head 5 and reproduced by a signal processing circuit 6. This reproduced code signal V'k is reproduced into the original signal V'i by a decoding/error correction circuit 7. The circuit 7 corrects errors in the coded signal by using a relative redundancy of V'k. The circuit 7 can see a signal supressor and when the signal Vk includes too many errors to be reproduced, the signal V'i is disconnected for a suppression. In order to continue a control in the case of disconnection, it is recommended that the track which includes the partially disconnected information pattern is not disconnected over the full length but that an non-disconnected information pattern is obtained between the disconnected information patterns.

Title: Mos transistor
Inventor: KAWAGUCHI TOSHIHIKO
IPC: H01L29/78
Filed: 1987-09-02
Abstract: PURPOSE:To form a gate without providing an impurity diffusion layer of low concentration and prevent hot carriers from being produced in a depletion layer of a drain junction, by forming the gate such that a gate length is uniform over the whole of the gate and a gate width is wider on the drain side of the gate than on the source side. CONSTITUTION:A gate 1 is formed such that its length l1 is uniform over the whole of the gate 1 and a gate width l2 on the drain 2 side is wider than a gate width l3 on the source 3 side. Hereby, density of an electric field in the vicinity of the junction of the drain 2 is reduced. This is because a junction area on the drain 2 side is increased by making the width of the gate 1 wider on the drain 2 side and hence extension of the depletion layer on the drain 2 side is reduced.

Abstract: PROBLEM TO BE SOLVED: To provide toner that generates little greasing even in case of using low temperature fixing type resin by using specific carbon black as a coloring agent. SOLUTION: In electrostatic charge image developing toner formed of at least a coloring agent and binder resin, with a melt index(M.I) being in a range of 5-30 g/10 min., carbon black with a volatile component being 3.0-5.0% and with DBP oil absorption being in a range of 50-72 ml/100 g is used as the coloring agent. As the binder resin, polyester resin with a polycarboxylic acid component and a polyhydric alcohol component as a constituent unit is used, but in this polyester resin, at least part of polyhydric alcohol is composed of oxyalkylene ether of novolak type phenol resin. As a result, low temperature fixing property and dispersibility of carbon black are improved. In addition, the weight average molecular weight of toner is specified into a range of 1.0×10<4> -9.0×10<5> so as to further improve the dispersibility of carbon black.
