Filed: 1997-10-13
Abstract: PROBLEM TO BE SOLVED: To enable speedy recovering operation by automatically performing log gathering for investigating the cause of a fault and restarting when the OS(operating system) of a computer gets down. SOLUTION: The fault monitor and automatic recovery device 1 is connected to a console port provided to a computer to be monitored by a cable. An abnormality detecting means 3 sends a monitor command to the console port of the computer at specific intervals and judges that the computer is abnormal when there is not response from the computer to the command.

Title: Focus detecting device
Inventor: KUSAKA YOSUKE
IPC: G02B7/28
Filed: 1988-11-07
Abstract: PURPOSE:To shorten an arithmetic time while maintaining focus detection accuracy by calculating a correlation quantity at different shift quantity pitch nearby a focusing point and where a defocusing quantity is large. CONSTITUTION:A couple of subject image signals are inputted to a focus detection arithmetic means 30 through a focus detection optical system 24 and a photoelectric converting means 25 to calculate the defocusing quantity from a correlative shift value. Then, when the correlation quantity is found, its variation is set to 1st fine pitch within a 1st shift quantity range indicating that an image is almost in focus. Further, the pitch quantity is set larger than the 1st pitch except within the 1st shift quantity range where the absolute value of the defocusing quantity is large. Consequently, the pitch is made fine nearby the focusing point where accuracy is required, but the pitch is made large at a distance from the focusing point where the accuracy is not required so much to shorten the arithmetic time.

Title: Marker interlocking with signal
Inventor: MATSUMURO YASUHIKO
IPC: E01F9/00
Filed: 1992-09-24
Abstract: PURPOSE:To make it possible to display the information of a signal, e.g. yellow flashing and red, blud or yellow display, on a position separated from the signal while interlocking with the signal by displaying the same information as the signal by means of an optical transmission hose. CONSTITUTION:The optical transmission hose 2 is embedded on the position of a pedestrian crossing. One end of the hose 2 is formed as an incident part 3 for receiving light from the signal 1. In the signal 1, a filter 5 to be switched to red and blue is arranged in front of a light source 4 and light passing the filter 5 is detected by the incident part 3. The hose 2 is formed by storing a viscous liquid-like, solid-like, or gel-like core in a flexible high molecular clad having a refractive index lower than that of the core. Light received by the incident part 3 is passed through the hose 2 and the same information as the signal 1 is displayed from the side face of the other end side of the hose 2. Thereby light projected from the crossing becomes the display of red or blue or the flashing light of blue while interlocking with the signal 1, so that walkers can be prevented from missing the display of the signal.

Abstract: PROBLEM TO BE SOLVED: To reduce resistance variations and temperature dependence of a diffusion resistance region, by making the surface density and diffusion depth of boron impurities identical in both an offset region and the diffusion resistance region. SOLUTION: In a selective oxidation step during a CMOS process, a selectively oxidized film 2 is formed, and a gate oxide film 3 is thereafter formed in an active region where a p-channel MOSFET is to be formed, and a gate electrode 4 is formed by polysilicon. Then, offset regions 5 formed by a p-type impurity of the p-channel MOSFET and a diffusion resistance region 7 formed by the p-type impurity are prepared by forming windows in a resist film using the same photomask, and the windows are ion-implanted with boron atoms under a predetermined condition. Then, a heat treatment is given so as to form the regions 5 and 7, which are low-concentration diffusion regions, simultaneously. By using the boron atoms as impurity species in the same step, the resistance variations and the temperature coefficient of the diffusion resistance region can be reduced.

Title: Thermal recorder
Inventor: KASAI SHUICHI
IPC: B41J11/00
Filed: 1990-10-18
Abstract: PURPOSE:To prevent a starting difference of rotation at both ends of a platen roller from occurring by providing, on the platen roller, a shaft consisting of a tapered core bar having outside diameters at right and left sides different from each other and a rubber part whose thicknesses at right and left sides are different from each other, wound on the core bar. CONSTITUTION:A taper is provided in a diameter of a shaft 3b of a platen roller 3 so as to make a rubber part 3a thick at a driving end. Consequently, a force of a driving shaft to rotate precedently is delayed by a large torsion for a rate of thickness of the rubber. Thus, delays due to rotations at the driving end and a reverse driving end are out, so that a thermal recording paper 2 can be conveyed uniformly. Accordingly, in printing by a thermal mechanism, when a sticking occurs and a void between characters occurs due to defective conveyance where printing intervals become irregular because of inappropriate printing timing, influence of the starting difference of the rotation of the both sides of the platen roller 3 on printing images can be reduced.
