Title: Manufacture of shadow mask
Inventor: TANAKA YUTAKA
IPC: H01J9/14
Filed: 1991-10-24
Abstract: PURPOSE:To easily peel residues off as well as to prevent electron beam pass holes from clogging by applying resistant agent mainly composed of specified material to an etching resistant layer formed after an early stage of a two-stage etching method. CONSTITUTION:First recessed holes 27 are formed by etching raw material 20 for a shadow mask from the side of a film 22 wherein resist films 22a and 22b are formed in a pattern corresponding to the electron beam pass holes of the shadow mask 31 on both the sides of the shadow mask. Next, the film 22b is peeled off, and etching resistant agent is then applied to the surface, so that an etching resistant layer 29 is thereby formed. Following which, second recessed holes 27 are formed by etching the raw material 20 from the film 22a side in a later etching stage wherein each second recessed hole is made a pass hole 31. When the aforesaid etching resistant agent is mainly composed of acryl resin, casein and leveling agent, the resistant layer 29 is easily dissolved by caustic alkali solution, residues can easily be peeled off, and the holes can be prevented from clogging.

Title: Production of silicon nitride
Inventor: KATO HAJIME
IPC: C04B35/591
Filed: 1984-12-28
Abstract: PURPOSE:To produce Si nitride having high alpha-content, easily in high stability,y adjusting the inner pressure of the furnace, thereby controlling the reaction of metallic Si in a hot nitriding atmosphere. CONSTITUTION:A bed or molded material of metallic Si is placed in an inert atmosphere having a reduced pressure of about <= 0.5atm, and heated at a temperature higher than 1200 deg.C (the nitriding initiation temperature) and lower than the melting point of metallic Si (1414 deg.C). An Si nitride having high alpha-content can be produced simply by introducing N2 gas so a to keep the N2 gas pressure in the vessel at a prescribed level or introducing N2 gas at a constant rate. If the rate of reaction is lowered by the imbalance of the amount of charged gas and the gas consumed by the reaction, the pressure in the furnace is raised to increase the rate of reaction. Inversely, when the rate of reaction is increased, the pressure in the furnace is decreased to decrease the reaction rate. Accordingly, the rate of reaction can be maintained at nearly constant level. When the amount of charging N2 gas is controlled in a manner to keep the heat generation of the reaction below the heat-quantity dissipated from the raw material, the reaction can be performed following a prescribed temperature pattern.

Filed: 1984-12-29
Abstract: PURPOSE:To prevent the omission of information as well as the crush of the information due to reduction by attaining the selection between a variable power record mode where the pictures are recorded and delivered after the change of the magnification so that they are included within an effective recording range of the recording paper having an external size equal to an original in an unmagnification record mode. CONSTITUTION:A switch 13 is switched to the +5V side to select a reduction mode within an effective recording range. In this case, a generator 37 for reduction clock within the effective recording range is selected in place of a generator 36 for unmagnification output clock. Thus the reduction is carried out in the main scan direction. While in a reduction mode of the secondary scan direction, the revolving speed of a step motor 1 is increased by an amount equal to a reduction ratio needed for reduction within the effective recording range compared with the revolving speed of the unmagnification mode.

Title: Card module
Inventor: SUZUKI KUNIAKI
IPC: G11C5/00
Filed: 1987-10-31
Abstract: PURPOSE:To avoid the miswriting actions due to the misoperations of a reader/ writer by inhibiting the data writing actions as long as the reader/writer has no output of high voltage necessary for writing actions. CONSTITUTION:A voltage detecting circuit 3 detects that the voltage of a read instruction line READ exceeds the level of the power supply voltage Vcc and sets the output at an LO level. Then a write instruction signal WRITE is applied to a memory chip 1 only when the output of an LO level is supplied to a gate circuit 4. Therefore data are never written just with the signal of the normal voltage even though any key logic is set at the reader/writer side. Thus it is possible to avoid the miswriting actions due to the misoperations of the reader/writer.

Title: System for recording and preserving light signal on photographic film then reproducing said signal
Inventor: HAYASHI KATSUYA
IPC: G11B7/003
Filed: 1987-10-31
Abstract: PURPOSE:To easily record and preserve an ample quantity of light signals on a photographic film and to improve the carrying and operating properties of a recording carrier by projecting and exposing the analogue or digitalized light signals to expose the photographic film to record and preserve the light signals and transmitting the light which is not signalized to the photographic film subjected to the recording. CONSTITUTION:The light signals are easily recorded on the photographic film simply when the light signals 2 emitted from a part 1 irradiated with the light signals are exposed to the photographic film 3. The light which is not signalized is merely transmitted through the photographic film 3 from the part 1 irradiated with the light signal at the time of reproducing the recorded light signals. The light signals are then projected in the opposite direction of the film 3 and the preserved light signals are received in a part 4 where the light signals are collected. An increase in the linear distance of the film 3 is prevented by taking up the film 3 on a take-up shaft 5 while running the photographic film 3 in an arrow direction. Recording is thereby executed for a long period of time and the photographic film can be easily housed to the shape met with objects and, therefore, the carrying and operating properties of the carrier are improved.

Filed: 1993-11-05
Abstract: PURPOSE:To provide a camera excellent in handleability on land and under water by properly softening a red-eye effect on land and prioritizing a shutter chance under water. CONSTITUTION:When the 1st stroke switch SW1 of a release switch 13 is turned on, photometry is performed by a photometry circuit. After obtaining information for AE control, an underwater sensor 12 consisting of a light emitting element 5 and a light receiving element 6 detects whether the camera is under water or not, and when it is under water, turning on a 2nd stroke switch SW2 is waited for without executing range-finding for AF, preliminary light emission for preparing light emission by a speedlight or lighting a red-eye softening lamp 16. When the 2nd stroke switch SW2 is turned on, range-finding operation is not performed, so that a focusing lens system is positionally controlled to a specified fixed point previously set. When it is dark, the speedlight is allowed to automatically emit the light, and when it is light, shutter releasing operation is executed without allowing the speedlight to emit the light.
