Title: Lithium secondary battery
Inventor: FUJIMOTO MASAHISA
IPC: H01M10/05
Filed: 1996-11-01
Abstract: PROBLEM TO BE SOLVED: To enhance the capacity of a battery by using a carbon material having a specified crystalline structure as the Li ion storing material of an negative electrode. SOLUTION: As Li ion storing material, a carbon material in which both a-axial and b-axial crystal sizes are 1000Å or more and the c-axial crystal size is 20Å or less is used. In charging, thus, the irregularly aligned La and Lb are inserted in a large quantity between small carbon crystalline grains of Lc without having a geometric limitation on the Li ion. Thus, the capacity of the battery can be more increased, compared with the case of graphite having a conventional layered structure. Such a carbon material can be obtained by inserting a precursor of the carbon material between the layers of a clay mineral such as montmorillonite followed by baking under vacuum at a high temperature of 1500-2000 deg.C, and finally dissolving and removing the clay mineral with acid.

IPC: G03G15/08
Filed: 1996-11-19
Abstract: PROBLEM TO BE SOLVED: To keep a satisfactory contact state between a cleaning blade and a photoreceptor surface and keep the cleaning performance over a long period by forming a strip apparent image pattern on this side of an ADC patch, and cleaning the strip apparent image pattern prior to the cleaning of the ADC patch. SOLUTION: When a latent image for forming an ACD patch 17, a latent image pattern extended in the lateral direction of a photoreceptor is formed on this side thereof followed by toner development by a developing equipment to form a strip apparent image pattern 23. The strip apparent image pattern 23 is passed through a cleaning blade prior to the cleaning operation of the ADC patch 17. Thus, since the quantity of non-transferred toner getting into the cleaner part is laid substantially in the same condition in the photoreceptor lateral direction, cleaning of the following ADC patch 17 image can be stably performed without suddenly adding a partial load to the cleaner. Thus, the cleaning performance can be kept for a long period without adding a local cleaning stress to the cleaning member.

IPC: G06F3/12
Filed: 1996-11-20
Abstract: PROBLEM TO BE SOLVED: To enable printing to be performed with a memory capacity which is smaller than a normal level without deteriorating an image quality, even when there are irregularities in the lengths of time for data development per printing process, in a printing process device which prints a single page through plural printing processes. SOLUTION: Print data is converted to tokens by a phrase analysis part 30 and the tokens are entered to a picture drawing process part 31 and a processing time estimating part 4. The processing time estimating part 4 receives the tokens and interprets a picture drawing command, and estimates an estimated time for a picture drawing process per band by the weighted addition of the picture drawing command for a character, a pattern and an image contained in the print data. The estimated time for a picture drawing process per band is outputted to an output control part 5 after summing up the lengths of time by page unit and color unit.  The output control part 5 decides a recording speed per color by an output part 6 based on a time for a picture drawing process per band which is forecast by the processing time estimating part 4 to start the output part 6 and at the same time, make it operate at the recording speed decided per color.

Title: Governor for engine
Inventor: TSUJI CHITOSE
IPC: G05D13/10
Filed: 1989-11-28
Abstract: PURPOSE:To stabilize output performance by thickly forming the thickness of the peripheral part of a thrust piece so that its inertia is increased. CONSTITUTION:The peripheral part of the sliding edge 11 of the thrust piece 8 is constituted as a thick part 12 so that inertia occurs at the time of rotating the thrust piece 8. When the rotational frequency of governor weights 5 and the thrust piece 8 around a cam shaft 2 is changed due to the load variation of an engine, a rotational frequency difference between the weights 5 and the piece 8 is temporarily generated by inertia based upon the thickness part 12 of the piece 8 and the sliding position of the sliding edge 11 from a sliding part 7 is successively shifted in the rotational direction. Thereby, the sliding contact of the thrust piece 8 with the governor weights 5 is uniformed over the whole periphery and the performance of the governor can be stabilized.
