Title: Line sensor
Inventor: NAKAMURA SHIGEO
IPC: H01L27/148
Filed: 1995-09-14
Abstract: PROBLEM TO BE SOLVED: To reduce the influence of the irregularity of a light source and the irregularity of the base by composing a sensor by a photodiode for a pattern signal and a photodiode for a correction signal in which plural photodiodes correcting the output signal of the photodiode for pattern signal are arranged side by side. SOLUTION: A signal is transferred from a photodiode PD1 for a signal to a CCD transfer path CCD1 and at the same time, the signal is transferred from a photodiode PD2 for signal correction to a CCD transfer path CCD2. Subsequently, the signal of the CCD transfer path CCD1 is amplified in an output circuit OUT 1 and a signal of 30kH or below is taken out by a low-pass filter LPF 1. The signal transferred to the CCD transfer path CCD2 is amplified in an output circuit OUT 2 and a signal for correction of low-pass components of 3kH or below is taken out by a low-pass filter LPF2. In an addition/ subtraction circuit, when the correction signal taken out by the low-pass filter LPF2 is added to or subtracted from the signal taken out by the low-pass filter LPF1, the low-pass components are eliminated from the signal.

Title: Wire-wound resistor
Inventor: HISHIYAMA TOMOYUKI
IPC: H01C3/00
Filed: 1991-06-12
Abstract: PURPOSE:To suppress the variation of resistance for higher reliability which may be caused by the aging of the contact between a cap and a resistance wire due to thermal stress in long time use in a temperature varying environment by attaching a cap with a projection to both ends of a porcelain and connecting the resistance wire to the projection to shorten the contact area between the cap and the resistance wire. CONSTITUTION:Connection between a resistance wire and a cap was conventionally provided at a deep point from the cut end of the cap. This lengthened the contact area between the cap and the resistance wire. Therefore, when the resistor was used for a long time in a temperature varying environment, the condition of the contact between the cap and the resistance wire sometimes changed due to thermal stress from the initial value, resulting in the variation of resistance. To cope with this, a cap 2 with a projection is used and a resistance wire 3 is connected to the projection. This suppresses the variation of resistance to improve the electrical characteristics for higher reliability.

Title: Manufacture of sealed nickel-hydrogen storage battery
Inventor: KAWANO HIROSHI
IPC: H01M4/26
Filed: 1983-12-16
Abstract: PURPOSE:To produce a long-life sealed nickel-hydrogen storage battery by adjusting the amount of electrolyte to the lower limit by performing charging in an excessive amount of electrolyte before sealing is performed. CONSTITUTION:A hydrogen-absorbing alloy having oxidized surface is not easily reduced when charged in a small amount of electrolyte. In the presence of a sufficient amount of electrolyte, however, the above hydrogen-absorbing alloy is easily reduced and the reduced alloy then absorbs hydrogen. Therefore a large amount of the electrolyte is necessary in order to achieve the state in which hydrogen is electrochemically absorbed. After such a state is achieved by performing charging in the presence of a sufficient amount of the electrolyte, the surplus electrolyte is discharged to adjust the amount of the electrolyte to the lower limit before sealing is performed.
