Title: Optical instrument member
Inventor: KAWANA ATSUO
IPC: G02B1/10
Filed: 1992-01-09
Abstract: PURPOSE:To form an optical instrument member having a black coating film which has a sufficient heat stability for high power beams by forming a TiAlN film on the surface. CONSTITUTION:The TiAlN coating film is formed on a surface of a masking blade which is used in an excimer laser optical system by an arc discharge-type ion plating device. The coating film is formed by generating arc discharge by applying a voltage between a TiAl alloy cathode whose TiAl alloy is an evaporating source and an anode of the instrument wall. The TiAlN is the substance having the structure in which a portion of Ti with a NaCl type crystal structure is substituted with Al and it is selected because the coating film is black. Thus when the member which the TiAlN film was formed on the surface is used, the oxidation and degradation of the coating film are hardly progressed even in the optical system using high power laser such as excimer laser, and the effects of preventing the reflection and scattering of light are obtained over a long period.

Title: Picture information storage device
Inventor: KANEKO SHUZO
IPC: G06F3/048
Filed: 1987-01-31
Abstract: PURPOSE:To obtain a paperless picture information storage device by using a sheet type member which forms a visible picture with pressure and at the same time gives the position information on the visible picture to a tablet and a memory which stores the information supplied to the tablet. CONSTITUTION:A light dispersing sheet 4 pressed by a pen 2 is adhered to a viscous surface 3 set under the sheet 4. The light dispersing state changes only at said adhered part and a picture is formed by transmission of the color tone of the surface 3. As a result, the input picture is drawn as it is on the sheet 4. Then the sheet 4 is removed from the surface 3 after input of the picture so that the input picture is erased. Thus the input of another picture is possible. A pressure-sensitive position detecting tablet 1 is used to store the picture in a memory as electric signals. In such a constitution, no paper is needed and an input device is obtained at a low cost.

Filed: 1989-01-31
Abstract: PURPOSE:To improve workability and to prevent casting defects as well as to cast products having high accuracy by embedding a runner into the heat insulating material in a heat resistant container, exposing product cavities and pouring basin and then executing casting. CONSTITUTION:A sufficiently heated casting mold body 1 is taken out of a heating furnace while being housed in the heat resistant container 2. A molten metal is poured therein from a spure 4.

IPC: B26D3/16
Filed: 1990-01-29
Abstract: PURPOSE:To cut a pipe in a correct length with its length at the normal temperature time as the reference, by sticking in advance an adhesive tape with a measuring scale to a pipe and marking a pipe cutting position with the use of the measuring scale thereof at the pipe line execution site. CONSTITUTION:The marking of a cutting position is executed based on a measure by a measuring scale, on the plastic pipe 1 which sticks a plastic tape 3 with a measuring scale in the length direction. The adhesive tape 3 is then peeled off, the peeled tape 3 is wound in the peripheral direction at the marking position and a pipe is cut with this wound tape 3 as the cutting marked line. Consequently, the cutting marked line can be expressed straightly in the peripheral direction, the cutting can be performed smoothly and with aligned cutting face, and the pipe 1 can be cut with a correct length accuracy, because of the measuring scale being contracted at the same ratio as that of the plastic pipe 1 even in case of there being the thermal contraction of the pipe 1.

IPC: G11B5/39
Filed: 1991-02-13
Abstract: PURPOSE: To eliminate Barkhausen noise by stabilizing a single magnetic domain magnetizing state in the active area of a magnetic resistance element. CONSTITUTION: Blocking capacitors 74 and 76 are directly connected onto a wafer with a magnetic resistance sensor 40 and conductors 78, 80, 82 and 84 are also directly connected onto the wafer.
