Patent JP-H10189949-A (JP)
Title: Mos semiconductor device and manufacture thereof
Inventor: TAKAHASHI HIROSHI
IPC: H01L29/78
Filed: 1996-12-24
Abstract: PROBLEM TO BE SOLVED: To prevent impurities from being diffused into a silicon substrate by introducing nitrogen, not into a gate electrode or the silicon substrate but only into the vicinity of a gate electrode and a gate oxide. SOLUTION: A gate oxide layer 2 is formed through thermal oxidation of a silicon substrate 1, and annealing is performed in an oxygen nitride (NO) atmosphere. A polysilicon electrode 3 is then formed by CVD and shaped into a gate electrode which is implanted with ions. Subsequently, a gate, a source and a drain are activated through doping and heat treatment. Since the silicon substrate 1 is subjected to laser annealing in an oxygen nitride atmosphere, energy of laser beam is absorbed by thermal oxide and since a temperature exceeding the critical reaction point of oxygen nitrogen is reached in the vicinity of the surface of the gate oxide layer 2 where the energy of laser beam is concentrated, nitrogen is distributed to form a nitrogen introducing layer 4.

Abstract: PROBLEM TO BE SOLVED: To read a document in without depending upon the operation of a printer and improve the productivity of copies and the operability of the device by dividing the read document size of a storage means into >=2 sheets, and inputting and outputting image data to the divided areas independently. SOLUTION: (1) Image data P2 of a document 1 while stored in a bank 1 are outputted to a printer. (2) The image data are read out of the bank 1 and the image data P1 of an output document 1 to a printer are stored in a bank 2. (3) The image data are read out of the bank 1 and outputted to the printer. Then the image area are read out of the bank 2 through (4)-(6) and outputted to respective printers, but in this practical mode, the read of the document ends at the stage (2), and the document can be taken away earlier; and the input to and output from an image memory are done simultaneously, so the process can be completed by one procedure earlier.

Title: Fly wheel
Inventor: HIEI ATSUSHI
IPC: F16F15/30
Filed: 1995-12-28
Abstract: PROBLEM TO BE SOLVED: To extremely reduce the size of broken pieces of a fly wheel at the time of fracture thereof and prevent a housing from being damaged by constituting the fly wheel from a main wheel made of a brittle material with its high specific strength and a sub-wheel made of a pair of brittle materials to be coupled so as to pinch the main wheel. SOLUTION: This fly wheel to be fixed to a rotary shaft is made of a carbon fiber reinforced resin wheel (main wheel) 2 of its long-diameter and ultra-high strength and a pair of a small-diameter ceramic wheel 1 functioning as a reinforcing material of this wheel 2, and these three wheels are integrally bound by means of a binder 3. If the ceramic wheel 1 is fractured, the wheel 1 is instantaneously broken into pieces because ceramic is a brittle material, the role of the wheel 1 as a reinforcing material of the wheel 2 is lost instantaneously, therefore, the carbon fiber reinforced resin wheel 2 is subject to a stress much higher than that flucture stress value and is broken into pieces.

Title: Digital servo device
Inventor: KAMOSHITA MIKIO
IPC: G05D3/12
Filed: 1992-12-24
Abstract: PURPOSE:To surely stop a head at the target position by compensating the integrated value of velocity errors when the moving control of the head is changed from coarse control to fine control. CONSTITUTION:An integrating part 21 for velocity error integrates the velocity error calculated in a calculating part 20 for velocity error and outputs the integrated error as a control signal. A generating part 23 for compensation value generates a compensation value or compensating the integrated value o the integrating part 21 decreasing the difference between the target and the current velocities. A compensating part 24 for integrated value compensates the integrated value of the integrating part 21 with a compensation value generated by the generating part 23 when the head control is changed from coarse control to fine control. Consequently, by compensating the integrated value of the velocity error when the moving control of the head is changed from coarse control to fine control, since the fine control is exactly executed, the head is surely stopped at the target position.

IPC: B31B50/59
Filed: 1997-11-28
Abstract: PROBLEM TO BE SOLVED: To improve sealability of a tray-shaped container made of paper which is formed of a paper board by adhering a lid material thermally to a flange. SOLUTION: Folding lines for inducing wrinkles are provided on a paper board blank comprising thermally adhesive resin 14 laminated on a surface of a paper 13, a molding with a small clearance at a flange with respect to a container side face is used to perform pressing under temperature conditions where a temperature of a female molding is higher than a melting point of the resin 14 and a temperature of a male molding is lower than the melting point. The wrinkle (f) at the flange is depressed by causing pressing pressure to be concentrated on the flange due to difference in clearance to improve smoothness of the flange surface, and also a tunnel-like communication hole is closed by the thermally adhesive resin 14.  Thus a seal may be prevented from coming off when a lid material comprising a film 15 and peel resin 16 laminated on a rear of the film 15 is thermally adhered, and also deterioration in sealability due to the tunnel-like communication hole is prevented.
