Title: Color image recording method
Inventor: SONODA YASUKO
IPC: B41J2/355
Filed: 1994-02-10
Abstract: PURPOSE:To improve a color reproducibility and a gradation in a highlight part having a low image density. CONSTITUTION:With respect to magenta pixels 18, adjacent pixels in a main scanning direction are shifted from each other in a sub-scanning direction by 1/2 pitch. With respect to cyan pixels 20 and yellow pixels 21, the pixels are grouped by 2 pixels in the main scanning direction. Cyan pixels of odd-numbered groups are shifted by 1/2 pitch in the sub-scanning direction. On the contrary, yellow pixels of even-numbered groups are shifted by 1/2 pitch in the sub- scanning direction. Therefore, since all colors are recorded in different dot patterns, a recording area in which ink is lapped on ink is reduced in a highlight part.

Inventor: TAKAGUCHI MASANARI
IPC: H01J37/244
Filed: 1998-01-29
Abstract: PROBLEM TO BE SOLVED: To prevent lowering of resolution and of S/N while maintaining high intensity of luminescence, by suppressing scattering of charged-particle beams in a phosphor for converting an incident corpuscular beam image into an optical image by applying an electric field to the phosphor from the exterior. SOLUTION: Firstly, a transparent electrode 17 is provided on the side of a fluorescence outgoing surface. Nextly, in order to use a conventionally provided reflection film 15 also as an electrode, a direct current power source 16 is connected between the film 15 and the new transparent electrode 17, and an electric field applied between the two electrodes. Higher potential is given to the side of the transparent electrode for the purpose of pulling electron beams in the direction of an incoming axis and thereby preventing their scattering. Because the optimum value of the electric field varies with energy of electron beams and the thickness of a phosphor, it is preferable that the direct current power source can change the electric field.  For the transparent electrode 17, thin oxide (SnO2 ), indium oxide (In2 O3 ), titanium oxide (TiO2 ), or the like, having both conductivity and light-transmissivity, is considered suitable.

Title: Switching power source circuit
Inventor: KANAMORI ATSUSHI
IPC: H02M3/155
Filed: 1999-01-26
Abstract: PROBLEM TO BE SOLVED: To provide a switching power source circuit the switching loss of which can be reduced further when the load is light. SOLUTION: When a switching power source circuit operates normally, a load current detecting circuit 4f detects a normal load current and sends a detect signal to a switching circuit 4e. The circuit 4e makes a switching element 2a for normal operation perform switching operations, at the duty ratio of a pulse outputted from a PWM comparator 4c by supplying a base current to the element 2a. When a load 6 becomes lighter, the detecting circuit 4f sends a signal indicating a load current for light load to the switching circuit 4e, because the load current decreases. The switching circuit 4e switches the object to be driven from the switching element 2a for normal operations to another switching element 2b for light load, the switching time of which is shorter than that of the element 2a by supplying the base current to the element 2b.

Title: Improvement of residual stress in steel pipe
Inventor: TANAKA SHINJI
IPC: C21D9/50
Filed: 1979-02-19
Abstract: PURPOSE:To prevent the development of stress-corrosion cracks by the procedure in which a great stress is brought about in any one desired side of steel pipe, subjected to tensile yielding, and then cooled to ordinary temperature so as to retain compressive stress in the portion so treated. CONSTITUTION:The steel pipe 1 is fitted with the gas, electric heat, or high-frequency induction heater 3 in such a way as to surround the welded junction 2. Then, the outside of the steel pipe 1 is heated and at the same time the inside of steel pipe is rapidly cooled by passing a cooling medium, e.g., water in the inside of the steel pipe, whereby a great tensile stress is caused in the inside surface layer of the steel pipe 1 and at the same time a compressive stress is caused between the inside and outside of the surface layer. Under such a condition, the steel pipe is cooled to ordinary temperature to retain the compressive stress in the inside surface of the steel pipe and also the tensile stress in the outside surface. Thus, the lowering of the fatigue strength of the outside surface can be suppressed to a minimum and also stress-corrosion cracking due to the compressive stress can be prevented.

IPC: B60R22/34
Filed: 1990-01-26
Abstract: PURPOSE: To prevent the occurrence of a tendency to be fastened against a user by a method wherein a second belt connection tool locked in a first position and a bracket is moved from the first position to a second position under a resistance force according to an external force exceeding a prescribed value, and returned as a result of the external force being lowered. CONSTITUTION: A seat belt buckle assembly 10 has a buckle 11 and a bracket 12 expandably joined together through a folded belt 16 by connection members 13 and 14. The two connection members 13 and 14 are guided in the grooves 30 and 31 of cover half-bodies 22 and 23. During this time, when an external force is not exerted by compression springs 19 and 20 interposed therebetween, the half-bodies approach each other, the effective length of a belt 16, namely, a distance between the buckle 11 and the bracket 12 is shortened. In this case, when an external force exceeding a prescribed value is exerted, the two connection members 13 and 14 are separated from each other against the spring forces of the compression springs 19 and 20, and the effective length of the belt 16 is lengthened. This constitution eliminates a tendency to fasten a user by an automatic lock retractor assembly.
