Title: Thermal head driving circuit
Inventor: FURUKAWA NOBUO
IPC: B41J2/36
Filed: 1987-12-01
Abstract: PURPOSE:To shorten printing time by providing a latch circuit, a counter and a comparator for comparing the output data from the latch circuit with the value of the counter, and driving the heat generating resistor of a thermal head by these elements. CONSTITUTION:Magnitude comparators 3-1-3-n compare the value of a counter with the values of latch circuits 2-1-2-n and, when the output of each of the latch circuits is equal to or larger than the value of the counter, '1' is outputted and, when said output is smaller, '0' is outputted. Therefore, when '63' is set to the latch circuit 2-1, the magnitude comparator 3-1 outputs '1' for 64 times until the counter 6 outputs '0-63'. The output of this magnitude comparator and an enable signal are added to each of AND circuits 4-1-4-n and, by taking the AND thereof, each of driver circuits 5-1-5-n is subjected to ON/OFF driving corresponding to printing gradation.

Title: Manufacture of semiconductor device
Inventor: YANO YUISUKE
IPC: H01L29/78
Filed: 1994-12-08
Abstract: PURPOSE: To reduce density of equipotential lines formed in the region at which a gate electrode overlaps with a heavily doped diffusion region and thereby improve the breakdown voltage, by forming the gate electrode into a T shape and forming the heavily doped diffusion region by self alignment relative to the upper part of the gate electrode. CONSTITUTION: Polycrystalline silicon 13, except its portion buried in a slit 11, is etched to form a gate electrode 12. Since the polycrystalline silicon 13 is formed in the slit 11 in a BPSG film 16 and PSG film 15, the cross section of the gate electrode 12 is T-shaped with its upper part larger than its lower part. When ion is vertically implanted in the semiconductor substrate 23 to form a heavily doped diffusion region 17, therefore, it is formed by self alignment relative to the upper part of the gate electrode 12. As a result the overlap of the heavily doped region 17 with the gate electrode 12 is reduced at the lower part of the gate electrode 12. This reduces the density of equipotential lines formed in the overlap region, and loosens the electric field, which improves the breakdown voltage.

Title: Camera housing
Inventor: ONO NOBUAKI
IPC: H04N5/225
Filed: 1998-10-26
Abstract: PROBLEM TO BE SOLVED: To prevent the exertion of an optical harmful effect and to obtain a good photographed image even if moisture sticks to the surface of a transparent optical element forming a photographic incident light path by using a light transmissive optical material with a photocatalytic coating on the surface as the material of the optical element. SOLUTION: Part of the front outer case 12 of camera housing 1 confronting the photographic lens part 22 of a camera 2 housed in the camera housing 1 is formed from a transparent optical element 13 obtained by forming a photocatalytic coating on the surface of an optical element comprising a light transmissive optical material. A coating of titania (TiO2) is, e.g. used as the photocatalytic coating. When the photocatalyst is excited with light, the surface of the photocatalyst is made highly hydrophilic and the water repellency of the surface is lost. Condensation to waterdrops is therefore prevented even if moisture sticks to the surface of the transparent optical element 13.

Title: Electron vacuum pump
Inventor: MUROTA MASAO
IPC: H01J41/20
Filed: 1999-10-27
Abstract: PROBLEM TO BE SOLVED: To provide an electron vacuum pump capable of effectively discharging a residual carbon compound gas from a vacuum vessel such as electron microscope. SOLUTION: The electrons generated from an electron source 3 are collected by a focusing electrode 4, multiplied by each dynode. The multiplied electrons collide with a residual gas in a vessel 1 to decompose it, generating carbon by oxidization or reducing carbon monoxide or carbon dioxide, which carbon adheres to the surface of the rear dynode. Thus, it is possible to separate the carbon from the residual carbon compound gas, and to fix it, so that the partial pressure of the carbon compound is reduced in the vacuum vessel. Namely, the carbon compound gas may be discharged from the vacuum vessel.
