Title: Disk cache system
Inventor: SAKAKURA TERUHIKO
IPC: G06F12/08
Filed: 1993-03-05
Abstract: PURPOSE:To provide the disk cache system which is improved in speediness, reliability, and efficiency. CONSTITUTION:A main processor 1 loads a program on a main memory 2 and performs necessary processing An I/O processor 4 inputs and outputs a file to and from a disk device 7 by controlling a disk cache memory 5 and a disk controller 6 connected to a local bus 8. The I/O processor 4 writes data, written in a cache block, to the disk device 7 unless there is a read/write request from the main processor 1 to the disk device 7. In this case, only cache blocks which are rewritten from the main processor 1 are written on the disk device 7 preferentially according to the attributes, thereby improving the efficiency.

Title: Crystalization
Inventor: NISHIOKA TAKASHI
IPC: H01L21/20
Filed: 1982-03-20
Abstract: PURPOSE:To form the layer of a large grain size crystal semiconductor or single crystal semiconductor by executing the first and second scanning by energy beam at a speed which is higher than that by which respective scanning region is crystallized or recrystallized and by executing the second scanning while the first scanning region is being melted. CONSTITUTION:A striped first scanning region A1 is formed by an energy beam 3 and is melted. Then, the striped second scanning region A2 is formed partly overlapping with the first scanning region A1 and is then melted. Here, the scanning for forming and melting the i-th scanning region Ai is carried out at the speed which is higher than that of crystallization or recrystallization and the (i+1)th scanning following the i-th scanning is carried out while the scanning region Ai is being melted. Thereby, crystallization or recrystallization of the scanning region A1 progresses from the side edge a1 toward the scanning region A2. Thereafter, crystallization or recrystallization of the scanning region A2 progresses toward the scanning region A3 from the scanning region A1 in such  a form as succeeding the progress of crystallization or recrysallization of the  scanning region A1, thus resulting in aggregate of large crystal.

Title: Image forming device
Inventor: MUKAI HIDEO
IPC: G03G21/10
Filed: 1986-03-04
Abstract: PURPOSE:To increase the degree of freedom of design and reduce the size, weight, and cost of an image forming device and prolong the life of a photosensitive body by providing a cleaning device which recovers residual toner without contacting before the photosensitive body reaches a developing roller from an electrostatic charging device. CONSTITUTION:At the time of the photosensitive body 18 reaches the cleaning device 22, residual toner 28a at an unexposed part of the photosensitive body 18 is scattered toward a cleaning roller 31 because the DC potential difference between the unexposed part and cleaning roller 31 is 900V and recovered in a housing 30 through the rotation of the cleaning roller 31, and thus the residual toner 28a at the unexposed part is cleaned, so that the 2nd copy has no fog. Then at the time of the photosensitive body 18 reaches the developing device 23, the potential difference between the developing roller 32 and the unexposed part becomes about 330V as well as the 1st copying operation and toner 28 on the developing roller 32 is scattered to the exposed part of the photosensitive body 28, thereby performing development.

Title: Production of porcelain enamel-coated hot dip-aluminized steel sheet excellent in design characteristic
Inventor: ANAMI KATSUMASA
IPC: C23D5/06
Filed: 1990-02-26
Abstract: PURPOSE:To increase the degree of freedom of pattern modification and to obtain a porcelain enamel-coated hot dip-aluminized steel sheet excellent in cubic impression and design characteristics by forming a second porcelain enamel layer in the form of discontinuous distribution on a first porcelain enamel layer of a hot dip-aluminized steel sheet. CONSTITUTION:The surface of a hot dip-aluminized steel sheet 1 is coated via a hot dip aluminizing layer 2 with a slip 3 to be a first porcelain enamel layer 4, e.g. by a spraying method. As the essential component of this slip 3, a frit having a melting point lower than that of the layer 2 and also having a linear expansion coefficient lower than that of the steel sheet 1 is used. Subsequently, the steel sheet 1 is burnt at a temp. between the melting point of the layer 2 and the melting point of the frit, by which the slip 3 is melted on the surface of the layer 2 and spread so as to be formed into the first porcelain enamel layer 4. Further, this layer 4 is coated in the form of discontinuous distribution with a slip 5 by means, e.g. of spraying. Then the steel sheet 1, after the above treatment, is heated again up to a burning temp. The burning temp. at this time is set at a temp. lower than the melting point of the layer 4. As a result, a second porcelain enamel layer 6 is formed on the layer 4, by which the desired porcelain enamel-coated hot dip-aluminized steel sheet can be obtained.

IPC: C07C45/29
Filed: 1985-03-08
Abstract: PURPOSE:To produce formaldehyde in high yield and catalytic activity, without producing water, by dehydrogenating methanol in the presence of a highly selective copper catalyst supported on silica gel. CONSTITUTION:An aqueous solution or organic solvent solution of a copper salt such as copper acetate, copper oxalate, copper oxalate, copper nitrate, etc. is added to a silica gel calcined at a high temperature (about 600-900 deg.C) to impregnate 0.1-6.7wt% copper to the calcined silica gel. The impregnated copper is heated at 200-500 deg.C in an inert gas to effect the decomposition of the copper salt and to obtain a copper catalyst supported on the silica gel. Formaldehyde is produced by the dehydrogenation of methanol in the presence of the above copper catalyst at 400-650 deg.C, preferably 450-550 deg.C. The methanol conversion is 6-36%, the formaldehyde selectivity is 75-85% and the water- content of the product is 0.5-2 wt%. A high catalytic activity can be attained by reducing the copper catalyst with hydrogen at a temperature equal tot he decomposition temperature after the decomposition of the copper salt.

Abstract: PURPOSE:To secure the durability and insertaility of a probe and, simultaneously, to improve a rinsing ability by forming at least the sectional outer shape of a flexible member in a modified shape like a flat, elliptic or 8-character shape, etc., except for a round shape. CONSTITUTION:The sectional outer shapes of a tube 2 and a head tip 3 are formed in the flat shape in which upper and lower parts are removed, and both right and left parts are formed in a circular arc shape made into one part of the same round. Further, in the head of the head tip 3, electrodes 5 and 5 for discharge to be positioned at the lengthwise both edge sides, respectively, are embedded in an exposed condition. A probe 1 for discharge stone crushing is penetratingly inserted into a round penetrating channel 7 of an endoscope. Since the outer shape is made into the flat shape, comparatively large passage spaces 8 and 8 are formed between the inner surface of the channel 7 and it. Consequently, since the sectional area of the passage to pass a rinsing liquid can be secured large, a channel resistance can be made small, and the rinsing ability can be improved.
