Title: Optical low-pass filter and its production and hollow package
IPC: H04N5/372
Filed: 1992-03-30
Abstract: PURPOSE:To constitute the entire part of an optical low-pass filter to be used for averting false signals of glass without allowing the layer of a photosensitive resin to remain. CONSTITUTION:This optical low-pass filter consists of a diffraction grating 3 disposed via protective glass 6 between an image pickup lens 1 of a solid-state image pickup device and a solid-state image pickup element 2. A substrate 3a supporting a projecting surface 3b and projecting surface 3b forming the diffraction grating of such optical low-pass filter is integrally formed of the same glass. The optical low-pass filter may be integrally formed of the same glass on the front surface of the solid-state image pickup element 2 side of the protective glass 6. The optical low-pass filter is preferably produced by applying the photosensitive resin on a glass substrate, subjecting the resin to exposing and developing treatments to form the diffraction grating of the photosensitive film, then subjecting the film to dry etching treatment, thereby forming the diffraction grating consisting of the glass over the entire part.

Title: Charging controller of battery
Inventor: KUMEHASHI TATSUYA
IPC: G05D1/02
Filed: 1990-03-23
Abstract: PURPOSE:To improve charging efficiency by stopping at least one operation of a voltage detection means or current control means or voltage control means for a preset period from the start of charging. CONSTITUTION:For a period from the start of charging to the point of time TK, a battery 1 continues to be charged with a high current of a predetermined value and reaches a specified voltage V0 at the point of time t3. A voltage detection means 6 detects this and gives a detection signal to a current detection means 5 and a timer 7. The timer 7 gives a measured time T1 to CPU8 and the CPU8 operates a charge-ending time T2 and gives it to a timer 9. Also, a current control means 5 changes a phase signal to that for switching a charging current to a small current. From the point of time t3, therefore, a charging power supply 4 lowers the charging current to be supplied to the battery 1 to conduct a supplementary charge. Then, when the time T2 is measured from the timer 9 at the point of time t4, a charge-ending command is given to the charging power supply 4.

Title: Applying method for sheet for construction works
Inventor: WATANABE SHIGETAKA
IPC: H01F27/24
Filed: 1979-06-11
Abstract: PURPOSE: To enable the prevention of breakage and cutting of a sheet irrespective of the presence of the pressure on the surface of the sheet even when unequal sinking occurs in the ground, by providing a bent part of the sheet in the boundary between a structure and the earth.  
     CONSTITUTION: The lower part of an impervious sheet 3 stretched on a structure 1 is bent along the structure 1. The bent part thus formed 31 is buried by earth and sand up to the level of the earth 2 adjacent to the structure 1, while the end of the bent part 31 is laid on and struck to the end 41 of another impervious sheet 4 laid on the surface of the earth. Since the impervious sheet located in the boundary part between the structure 1 and the earth 2 has the removable bent part 31 in this way, the sinking of the ground and the resultant unequal sinking of the earth 2 make the bent part 31 open and follow the sinking and thus the sheets 3 and 4 can be saved from the forced extension. In addition, the same effect can be expected on the occasion of unequal sinking of the structure 1, as well.

Thereupon, the roof 18 serving to arrest the invasion of water droplets and cold air, and the fin-shaped hydro-extractor 18a serves to prevent water droplets from going around the back side of the roof 18 owing to surface tension. Thus, defrosted water dropping from the condenser 10 is prevented from entering the feedback passage 17 and is further prevented from dropping onto the refrigeration chamber 3.
