Filed: 1996-01-10
Abstract: PROBLEM TO BE SOLVED: To enable to prevent a void from being generated in an image even at a high raster scan speed outputting either of sets of data stored in memory or developed by a real-time developing means, based on calculated development time for each of the lines of an image. SOLUTION: CPU 20 operates RAM 24 as a work area in accordance with a program stored in ROM 22, then reads an image in page descriptive language, from an input device 28, which is stored in a hard disc 26 to develop the image into an intermediate language, and prepares a display list to store it in a band buffer 32. In addition, the CPU 20 calculates development time for each of the lines of the image and preliminarily develops the line image whose development time is longer than raster scan time. On the other hand, the CPU develops the image in the real time mode along with the raster scan, and outputs either of the sets of data stored in memory or developed in the real time mode per line based on the development time.  Therefore, in case the image developing process does not coincide with the raster scan by an image output device 16, the image is compressed per line and expanded for a switching process to improve the image quality.

Title: Magnetism detector
Inventor: FUKUDA KATSUYOSHI
IPC: H01L43/06
Filed: 1988-01-11
Abstract: PURPOSE:To improve sensibility by forming an active layer sensitive to magnetism onto a semiconductor substrate and specifying the ratio of a distance of the area where current flow in the active layer to a distance of the area where magnetoelectromotive force perpendicular to the former distance is generated. CONSTITUTION:An active layer 6 sensitive to magnetism is shaped on a semiconductor substrate 1, and the ratio W/l of a distance l of the area where current flow in the active layer 6 to a distance W of the area where magnetoelectromotive force perpendicular to the distance l is generated is set three or more. The relationship between the W/l and relative sensitivity is shown in the graph, but the sensibility is not increased so much when the W/l is above 3 though it has an inclination in which it augments together with the W/l as a whole. When the relative sensitivity is increased, there is an optimum ratio because the rate of increase is reduced. When the W/l is increased, the output impedance increases depending upon the W/l. Accordingly, a magnetism detector having high sensitivity is acquired.

Title: Sealed type lead-acid battery and its manufacture
Inventor: YOSHIDA TAKAMASA
IPC: H01M10/34
Filed: 1983-01-10
Abstract: PURPOSE:To prevent life decrease which is generated with the height of electrode plate by increasing electrolyte concentration in the upper part of an electrode group than that in its lower part in a sealed type lead-acid battery using fine glass fiber mats. CONSTITUTION:Since electrolyte is adsorbed in a fine glass fiber mat instead of flowing in a container, electrolytes having different concentration are readily kept in the container. For example, at first, electrolyte having high concentration is poured and held in fine glass fiber mats. Next, when electrolyte having low concentration is poured, since the upper part of an electrode group is filled with concentrated electrolyte, this second electrolyte moves to the lower part of the electrode group from gaps in the side. Therefore, high and low concentration parts are formed. Effect on mixing ratio of concentrated electrolyte having a specific gravity of 1.33 to total amount of electrolyte is investigated. When a mixing ratio is 40% (concentrated electrolyte), life s increased 50% or more as shown in the figure.

Title: Kitchen utensils and manufacture thereof
Inventor: CHENG STANLEY KIN-SUI
IPC: C25D11/16
Filed: 1999-01-08
Abstract: PROBLEM TO BE SOLVED: To prevent kitchen utensils from simply wearing another surface and to prevent a mark or a flaw is easily caused on the upper surface of a setting table or the cooking surface of a cooking stove by executing both of grinding processing and hard anodizing processing to an aluminum surface. SOLUTION: A kitchen utensil is obtained by forming from a nearly flat material blank, punching by a screw press, etc., to be in a desired form and pulling out by a die to form side walls to face upward from a base. A surface is ground before/after the hard anodizing processing. In particular, concerning an outer surface, grinding is executed by plural processes by using a fast grinding wheel and at the time, a minute cloth is used corresponding to the case. In addition an abrasive is also used. When corrosiveness is too strong, the abrasive bites into an anodizing processed layer but when corrosiveness is too weak on the contrary, a sufficient effect is not obtained, therefore it is important that the corrosiveness is neither too strong nor too weak.  In the case of a bottom wall, as the outer surface is an area receiving the largest deformation, it is convenient to use a relatively rough loth first.

Title: Output controller of tristate output circuit
Inventor: SUGANUMA KAZUO
IPC: H03K19/003
Filed: 1981-01-12
Abstract: PURPOSE:To evade the collision between output signals on a bus line, by supplying an output permitting signal to a tristate output circuit only when the bus line has high impedance. CONSTITUTION:When a bus line 1 is occupied by some output circuit, a signal 0 appears on the output signal line of an AND gate 8 connecting the output signal lines 6 and 7 of comparators 2 and 3. Therefore, no output signal appears on a signal line 18, so any output permitting signal is not supplied to a tristate output circuit 13. On the other hand, when none of circuits 13 outputs data to the line 1, namely, when the line 1 has high impedance, signals 1 appear on both the output signal lines 6 and 7, so a gate 12 is opened to supply the output permitting signal to the circuit 13. Consequently, the output data of a data generating circuit 14 is transferred to the line 1 under the control of a control circuit 11.
