Title: Maintenance method for forming device for electrode foil used for aluminum electrolytic capacitor
Inventor: KUNUGIHARA HIROSHI
IPC: H01G13/00
Filed: 1989-01-27
Abstract: PURPOSE:To make it possible to perform the maintenance of a forming device easily by dissolving and removing aluminum hydroxide attaching to a converting tank, making an acid aqueous solution circulate in the forming tank. CONSTITUTION:Particles of aluminium hydroxide produced in a forming process are chemically amphoteric compounds, and it is very difficult for them to dissolve in aqueous solutions almost neutral but it is very easy for them to dissolve in acid aqueous solutions. By utilizing this property and making an acid aqueous solution circulate in a tank, aluminum hydroxide particles attaching to the forming tank are dissolved and removed. For example, if solid aluminum hydroxide 10g is tried to be dissolved in an aqueous solution 100cc of sulphuric acid or nitric acid (density 5%) under a condition of 60 deg.C, 30min., it can be dissolved completely. In addition, it is very easy to wash out the aqueous solution and its removal is simple. This makes it possible to dissolve and remove the aluminum hydroxide easily. Accordingly, the efficiency of the maintenance of the forming device and the quality of electrode foils can be enhanced.

Title: Optical pickup device
Inventor: KURATA YUKIO
IPC: G11B7/135
Filed: 1989-01-27
Abstract: PURPOSE:To reduce the intensity of an Airy ring of a laser spot and to prevent the occurrence of cross talk even when the width of a recording track is narrow by setting zeroth-order light diffraction efficiency in the middle part of a grating pattern of an optical element as larger than zeroth-order light diffraction efficiency in the side part. CONSTITUTION:The zeroth-order light diffraction efficiency in the middle part of the grating pattern 2 for branching a laser beam emitted from a laser light source 1 into three beams is set as larger than the zeroth-order light diffraction efficiency in the side part. In other words, a zeroth-order light transmission quantity in the side part is suppressed lower than a zeroth-order light transmission quantity in the middle part. Consequently, the laser beam with high intensity in the middle and low intensity in the peripheral part can be obtained without partially cutting the quantity of laser beam light. By this method, the intensity of the Airy ring of the laser spot is reduced, and the occurrence of cross talk due to an adjacent recording track being irradiated with the Airy ring is eliminated.

Title: Logic circuit
Inventor: HIRANO YOUJI
IPC: H03K19/086
Filed: 1980-02-18
Abstract: PURPOSE:To avoid an increment of the rise time, the breaking time and others regardless of an increment of the number of input transistors, by installing a multi- emitter type transistor between the load element and each collector of a plural number of input transistor groups. CONSTITUTION:The emitters of the multiemitter type TRQ7 are connected to the collectors of the input transistors TRQ1-Q5 each, and the base of the TRQ7 is connected to the constant voltage terminal 11. And the collector of the TRQ7 is connected to the voltage source 2 via the load resistance R1. Then the NOR output is extracted out of the collector of the TRQ7; while the OR output is extracted out of the cpllector of the reference TRQ6. The collector capacity of the TRQ1-Q5 is separated by the function of the TRQ7, and at the same time the change is reduced for the collector potential of TRQ1-Q5 to reduce the Miller effect. Thus the time constant of the load resistance part is substantially decided by the product of the collector capacity of TRQ7 and the resistance R1. As a result, the collector capacity can be reduced to reduce the time constant of the load resistance part. Thus the rise time, the breaking time and the propagation delay time can be reduced.
