Title: Production of color filter
Inventor: SAKAKAWA MAKOTO
IPC: G02B5/20
Filed: 1990-06-06
Abstract: PURPOSE:To completely dissolve away residues and to securely fix a top coating resin to a substrate by applying a photosetting resist contg. a pigment onto the substrate and patterning the resist by a photomechanical process, then repeating plural times the dissolution and removal of the residues of the unexposed photoresist by an acid or solvent. CONSTITUTION:The photosetting photoresist R is uniformly applied over the entire surface of the substrate 1 by each one color for all of the colors constituting the filter and thereafter, the patterns P are formed by the photomechanical process technique consisting of exposing and developing process. The residue R2 of the unexposed photoresist are dissolved away by the acid or solvent at every formation. The stage for dissolving away the residues of the unexposed photoresist is repeated plural times to form the patterns P over the entire color; thereafter, the pattern forming parts are overcoated. The sticking of the residue R2 of the unexposed photoresist to the substrate is obviated even after the patterns P are repetitively formed for all the colors. The easy peeling of the over coating agent does not arise any more even if the over coating agent is applied to the pattern forming parts.

Title: Method for detecting focus error
Inventor: SHIBATA NORIO
IPC: G11B7/09
Filed: 1988-06-16
Abstract: PURPOSE:To make adjusting easy and to improve reliability by obtaining an error signal corresponding the difference of the image forming condition of reflecting light beam focusing on a light receiving element part through first and second cylindrical lenses. CONSTITUTION:When a light receiving element 35 is located at the position of B of a figure and the light quantities of light receiving elements 35a and 35b are same, an error signal becomes '0'. Moreover, when the light receiving element 35 is located at the position of C, it becomes an opposite condition from the condition when the light receiving element 35 is located at the position of A, and a focus error signal becomes reversed polarity. Thus, the focus error signal which is necessary to control a objective lens 32 to always keep a fixed clearance to a disk 31 can be obtained. As it is mentioned above, since it is not necessary to adjust an optical axis strictly to the center of the light receiving element like an astigmatism method, adjusting in a device to which it is applied becomes easy.

Filed: 1993-05-27
Abstract: PURPOSE:To quickly execute the revision of the mode or the capability even when out of synchronism takes place frequently and tentativity in an area by providing a fault notice means executing a fault notice as the occurrence of a fault when an internal timer expires. CONSTITUTION:A terminal equipment desiring the revision of the capability and the mode sends a BAS command code including the capability and the mode after the revision to an opposite terminal equipment according to the CCITT recommendations H.242. In this case, an internal timer 15A of an interconnection procedure control section 15 is started and the BAS command code is sent to an opposite terminal equipment. When an A bit of the reception signal from the opposite terminal equipment is logical 1, whether or not the internal timer 15A expires is discriminated and when the internal timer l5A is not expired, the preceding step is restored. When the A bit of the reception signal from the opposite terminal equipment is logical 0, the internal timer 15A is reset. On the other hand, when the A bit of the reception signal is logical 1 and the internal timer 15A is not expired, it is reported to its own terminal equipment as a fault.

Title: Controlling method for semiconductor device
Inventor: YAMADA SHINICHI
IPC: H01L29/74
Filed: 1991-06-20
Abstract: PURPOSE:To simplify a semiconductor device by connecting a plurality of current-control type semiconductor elements in series and supplying a gate current volume corresponding to the turn-on delay time of each element. CONSTITUTION:First, 3 semiconductor elements 1a, 1b and 1c are connected in series and a sharing resistance R2 is connected to respective element in parallel. These elements are activated through this circuit. The gate signal timing is respectively fine-adjusted by means of each element to obtain a proper voltage sharing. In the case where respective turn-on delay time of the elements 1a, 1b and 1c is tda<tdb<tdc, the gate current is supplied the respective elements at the ratio of IGa<IGb<IGc so as to make the timing of each gate signal to be identical. Therefore, even though respective turn-on delay times of the semiconductor elements are different or the gate signals are issued at the same timing, each element can be operated in series without withstanding excessive voltage at the time of turning-on, resulting in the semiconductor elements suitable for large-capacity high frequency power supply.

Title: Abrasion resistant composite cylindrical casting and composite roll and production of these
Inventor: NAKAGAWA YOSHIHIRO
IPC: B22D13/02
Filed: 1980-10-21
Abstract: PURPOSE:To contain W efficiently only in the part where abrasion resistance is required by differing the amt. of W of an alloy base material for a cylindrical casting between the outside surface side and the inside surface side. CONSTITUTION:In the case of casting a composite roll consisting of, for example, an outside shell 1, and an inside shell 2 by centrifugal force, a metal mold 4 with sand molds 5, 6 is rotated on rollers 3, and the molten metal for the outside shell in a laddle 8 is cast through one end of the opening, whereby an outside shell 9 is formed. This material is an alloy material provided with the performance necessary for the outside shell of the roll, and it is cast under addition of WC powder with a pouring basin 10 or the like during this casting. However, the WC powder is added continuously only to the molten metal forming the wall thickness on the outside surface side of the outside shell part to be subjected to rolling in actuality, and the casting is once stopped there, after which the molten metal not added with the WC powder is cast. Then, a stepwise change in the amt. of W is given in the wall thickness direction of the outside shell, whereby the amt. of mixing of W in the inside shell material is kept fairly low. After the casting of the outside shell, the inside shell material is cast therein. The production is carried out in the same manner as well in the case of providing abrasion resistance to the inside surface.

First, a solution of a coloring matter of formula ( I ), wherein X is halogen, in an organic solvent (the dye may be mixed with arachic acid) is poured dropwise on a water surface in a water tank, and is spread to obtain a monomolecular film. Next, while compressing the monomolecular film under a fixed surface pressure, a substrate so disposed as to orthogonally traverse the water surface is repeatedly moved up and down a desired number of times, thereby transferring the film onto the substrate. Accordingly, the J-associate product in which the molecules of the coloring matter are oriented and arranged in a special aggregated condition can be obtained.
