Title: Lithium secondary battery
Inventor: NAGAI TATSU
IPC: H01M10/058
Filed: 1987-11-10
Abstract: PURPOSE:To increase energy density per volume and weight of a battery by separating a positive electrode side from a negative electrode side with a separator through which ions are transferred but a solution is not transferred, and pouring a high concentration electrolyte onto the positive electrode side and a low concentration electrolyte onto the negative electrode side. CONSTITUTION:A positive electrode 1 side and a negative electrode 2 side are separated with a separator 3 through which ions are transferred but a solution is not transferred. A high concentration electrolyte 5 is poured onto the positive electrode side and a low concentration electrolyte 6 is poured onto the negative electrode side. Since the positive electrode 1 using a conductive polymer is set in a high concentration electrolyte chamber, the amount of anions in the electrolyte is large and a large amount of electrolyte is not required there. Energy density per volume and weight is therefore increased. Since the negative electrode 2 comprising lithium or lithium alloy is set in a low concentration electrolyte chamber, the reaction of lithium deposited in charge with the electrolyte is reduced and reversibility is not damaged. A lithium secondary battery having high energy density and excellent charge-discharge cycle performance is obtained.

Title: Gain controller
Inventor: ABE HIROYUKI
IPC: G05B11/36
Filed: 1993-11-15
Abstract: PURPOSE:To enable gain control so as not to listen to any noise of a disturbance source by supplying a disturbance signal to a servo loop when a regenerative output level corresponding to a read signal is higher than a prescribed value. CONSTITUTION:A reading means 2 reads information from a recording medium 1, a servo means 9 controls the position of the reading means 2 so that the reading means 2 can be positioned away from the recording medium 1 just for a prescribed distance, and a gain control means 8 changes the control by injecting the disturbance signal to the servo loop. Then, a level detection part 7 existent inside the gain control means 8 detects an audio signal level corresponding to the read signal provided from the reading means 2 and sets the gain control means 8 so as to generate disturbance when this level gets higher than an audio level at a certain degree so as not to make obvious noise caused by the injection of disturbance at the time of automatic gain control and therefore, the automatic gain control is performed only when the level is higher than that value. Thus, the noise caused by disturbance injection can be decreased in the sense of hearing.

Title: Ink jet recorder
Inventor: O RITSUZAN
IPC: B41J2/125
Filed: 1998-10-07
Abstract: PROBLEM TO BE SOLVED: To obtain an ink jet recorder in which a mode for attaining high quality recording by performing preheating or a mode for recording in a short time with lower record quality can be set selectively. SOLUTION: When the temperature of a recording head 3 is lower than a reference temperature and a switch 8 is set with a high quality recording mode, preheating is performed with a drive pulse of small pulse width causing no bubbling of ink. When the temperature of the recording head 3 reaches the reference temperature, recording is performed with a drive pulse of large pulse width for ink jet. Preheating requires a time but high quality recording can be carried out. When the temperature of the recording head 3 is lower than the reference temperature and the switch 8 is set with an immediate recording mode, preheating is not performed but recording operation is started immediately with the drive pulse of large pulse width for ink jet. Recording time is short because preheating is not performed although print quality is low.  A user can select a mode depending on the use through switching operation.

Title: Formation of reversal image
Inventor: WATANABE YOICHIRO
IPC: B41M5/323
Filed: 1988-11-11
Abstract: PURPOSE:To easily form a reversal image by heat-treating diazo photosensitive sheet containing diazonium salt at a part corresponding to image information by the use of the thermal head of a heat sensitive recorder, and then performing a diazo developing step. CONSTITUTION:Diazo photosensitive sheet is heat treated at a part corresponding to an original image by the thermal head of a heat sensitive recorder. Thus, the part of the sheet corresponding to the image is thermally decomposed at its diazonium salt. Then, the sheet is treated in a diazo developing step. Since the sheet developed in the step is not exposed, the salt is subjected to a coupling reaction to color. However, since the part corresponding to the original image heat treated by the head is thermally decomposed at its salt, a coupling reaction does not occur not to color. As a result, a reversal image uncolored at the image and colored at the background is formed.
