Title: Image forming device
Inventor: TANAAMI HIDEYUKI
IPC: B41J2/205
Filed: 1990-06-06
Abstract: PURPOSE:To read density irregularities correctly by a method wherein after being released from the feed state by a feed system of a large inertia, a recording medium is fed by a feed system of a small inertia to a reading position. CONSTITUTION:In reading a pattern of color irregularities of two or more colors printed on a sheet of recording medium 2, a discharge roller 42 is slightly rotated after a Cyan test pattern is read, and a Magenta test pattern is read. In a similar manner, Yellow and Black test patterns are read in order. The recording medium 2 is discharged to a reference position free from the feed action of a large-inertia carry belt 40 and stopped. After the electrified state for pressing the recording medium is released, a small-inertia discharge roller is reversely rotated. When reaching a reading position, the reverse feed is stopped, and the recording medium is again electrified. In this manner, it is not required that a separate area between a carry system (e.g. a belt) for feeding the medium to the recording position and a feed system (e.g. a discharge roller) for feeding the medium to the reading position should be large.

Title: Magnetic disk driving device
Inventor: TSUYOGUCHI TORU
IPC: G11B21/10
Filed: 1986-06-24
Abstract: PURPOSE:To obtain a magnetic disk driving device in which the possibility of accidental erasure is precluded even with mis-track by using a track identification signal written in a recording track so as to identify the recording track and a servo track at formatting. CONSTITUTION:Whether or not a track is a track subjected to formatting is discriminated by detecting the presence of a track identification signal P and the formatting is executed only when the track identification signal P is detected. That is, a signal detected by a magnetic head 2 is amplified via a head amplifier 21 and a band pass filter 40, an envelope detector 43 and a comparator 41 discriminate the track identification signal P. When the track identification signal P is confirmed, a format enable signal is sent from a detection circuit 42 to a driving circuit 22 to apply formatting. Thus, even if a magnetic head 2 steps out in mistake, since servo tracks ST1-ST4 are not formatted, the possibility of erasure of a servo signal F is precluded.

Title: Wheel made of expanded metal
Inventor: SASAKURA TETSUTARO
IPC: B60B19/00
Filed: 1995-05-09
Abstract: PURPOSE: To prevent the side slip and racing of a wheel during traveling or working of a working vehicle on a rough land and assure the safety of a work by using an expanded metal on an outer periphery which is the grounding surface of the wheel and installing a side plate formed by saw type teeth on both end parts of the wheel. CONSTITUTION: An expanded metal 1 is used on an outer periphery which is the grounding surface of a wheel. A side plate 2 formed by saw shape teeth is installed on both end parts of the wheel and installed to a drive shaft by a flange 3. A side slip racing or the like can be prevented even under a bad condition such as a sharp slope, a soft land, an earth and sand surface, a grassland and a snowland, or the like because of that the stitch of the expanded metal 1 is rotated by catching the land surely and the side slip is prevented by the eating away of the saw shape side plate 2 to the land. As the earth and sand wound up by the rotation of the wheel is spilled out from the stitch of the expanded metal 1 and piled up on the grounding surface of the wheel again, the wheel is not burried in the earth and sand. Also, the cost of the wheel is cheap.

Title: Method for controlling temperature of holding device for continuous casting billet
Inventor: KIYOUJIMA YOSHIYUKI
IPC: C21D9/00
Filed: 1983-08-12
Abstract: PURPOSE:To prevent cracking of a billet in the stage of rolling by providing a billet holding device in front of the inlet side of an inline reduction rolling mill used in a high speed continuous casting device, allowing said device to cool naturally for the prescribed time determined by the calculation equation and heating the same for the prescribed time in succession thereto. CONSTITUTION:A billet holding device is provided in front of an inline reduction rolling mill in a synchronous rotation type continuous casting device. When, for example, the billet temp. decreses to about 900 deg.C or below since end of casting until the succeeding casting, the heat of the billet in the holding device is compensated by burners. The holding device is allowed to cool naturally for the time determined by the equation t2=-tauln[1-(Tm-Ts)/T0] -tauln(Ts/Toff) and is heat ed for the time determined by the equation t3=-tauln[1-(Tm-Ts)/T0]. T0, Toff, Tm, Ts are the max. temp. of the holding device, the temp. when casting ends, the target temp. and the temp. when the burners are assumed to be not ignited and tau is a constant. The temp. of the billet is thus adequately controlled and the cracking of the billet during rolling is eliminated.

Title: Preparing semiconductor device
Inventor: TADAMA NAOTAKE
IPC: H01L21/31
Filed: 1978-11-28
Abstract: PURPOSE: To prevent a wiring from breakage due to step-structure by a method wherein an insulator layer is formed to the same level as an element forming surface of a substrate and at a low temperature to prevent a diffusion layer from redistribution and thermal strain.  
     CONSTITUTION: A thin SiO 2  layer 9 is formed on the Si substrate 8. Etched grooves 11 are formed on the substrate 8 through the resist mask 10 by using vertical ion beam projection. Then ion injection is used to form a diffusion layer 12 to prevent an inversion layer from forming. High purity silica plate SiO 2  is irradiated with ion beam to produce Si particulates which are deposited on the grooves 11 until they form an insulator layer 13 to reach nearly the same level with the surface of the substrate 8. The structure provides a flat surface, high-accuracy protoetching without causing wiring breakage. Furthermore, the insulator layer 13 is formed at a low temperature, eliminating soil and strain at high temperature production. Thus, the substrate is effective in producing semiconductor device having an excellent property.
