Patent number: 6628269Abstract: A touch panel input device includes layers A and B. Layer A includes a first transparent film, a first transparent resistive film, a second transparent film, a second transparent resistive film, and first dot spacers. Layer B includes a second transparent film, a third transparent resistive film, a fourth transparent resistive film, a glass substrate, and second dot spacers. When the device is operated by a finger, the device detects a contact state of the transparent resistive films in layer A and a non-contact state of the transparent resistive films in layer B. When the device is operated by a finger, the device detects a contact state of the transparent resistive films in layer A and a contact state of the transparent resistive films in layer B. Regardless of the input mode, information of a position thus inputted can be detected.

Patent number: 6586983Abstract: A signal phase adjustment circuit to set an optimum phase by adjusting the difference in delay times between signal lines even when the distribution of the amount of phase modification that can be received normally is divided into a plurality of continuous regions. The amount of phase modification of the transmitted signal is allowed to fluctuate during one cycle of the operational frequency of the circuit. Determination of whether or not the reception signal during this interval can be received is continued, and the distribution of amount of phase modification that can be normally received is detected. The detected amount of phase modification defines continuous regions, and an optimum phase region is specified by selecting a region having a width of a specified value or more or the region having the greatest width. The optimum amount of sampling phase modification is determined from the upper and lower limit values of this region.Type: GrantFiled: March 22, 2002Date of Patent: July 1, 2003Assignee: Fujitsu LimitedInventors: Jun Tsuiki, Toshiyuki Shimizu

Patent number: 6391488Abstract: The present invention relates to an improved non-aqueous electrolyte cell comprising an anode, a cathode and a separator spirally wound so that the anode is disposed on the outer side of the cathode to form an electrode assembly. The outermost end of the cathode is wrapped with an electrically insulating material, the anode has a section provided with an anode current collector in the vicinity of the outermost end thereof, and the section is positioned beyond the wrapped outermost end of the cathode. A reaction suppressing layer is present between a cathode section in the vicinity of the outermost end and the anode positioned on the inner side thereof, thereby only the outer side of the cathode section substantially reacts with the anode. This cell ensures disconnection of remaining non-reacted anode component from the current collector when forcedly discharged at the last stage of discharge, causing little capacity loss.Type: GrantFiled: July 6, 2000Date of Patent: May 21, 2002Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Toshiyuki Shimizu, Hideki Fukuda, Toshiya Kuwamura, Takayuki Tanahashi

Patent number: 6334356Abstract: This invention relates to a method for deciding an amount of correction factor for the viscosity of a fluid test sample needed for correcting a calculation or measurement of the density based on the viscosity. The method for deciding the viscosity of the fluid test sample, during a density measurement performed by an oscillating densitometer where there is a peak point on the viscosity-attenuation constant characteristic of the test sample at the specific order oscillation, is to decide whether the attenuation constant of the viscosity-attenuation constant characteristic of the test sample at the other specific order oscillation is larger or smaller than that corresponding to the peak point, to decide according to said decision whether the viscosity detected by the attenuation constant obtained at the specific order oscillation belongs to either side larger or smaller than the peak point, and then to decide upon and determine the viscosity of the test sample according to the above two decisions.Type: GrantFiled: October 15, 1999Date of Patent: January 1, 2002Assignee: Kyoto Electronics Manufacturing Company, LimitedInventors: Toshiro Kita, Kenji Kawaguchi, Toshiyuki Shimizu

Patent number: 6326824Abstract: An initial value generation circuit generates an initial value taking into consideration the a time delay when a signal is transmitted through the signal wires between a pilot device and other devices, and a processing delay caused in respective devices. When a device receives a system synchronizing signal form another device, the device sets an initial value in a counter. Thereby, the counter value of a counter in a pilot device and counter values of counters in the other devices are made to coincide with each other.Type: GrantFiled: July 27, 2000Date of Patent: December 4, 2001Assignee: Fujitsu LimitedInventors: Koji Hosoe, Jun Funaki, Toshiyuki Shimizu, Michio Numata
