Title: Shadow mask
Inventor: YUKI NORIO
IPC: C22C38/08
Filed: 1989-12-22
Abstract: PURPOSE:To prevent the occurrence of adhesion at the time of annealing and to improve annealing yield by properly controlling respective surface roughnesses of shadow mask materials composed of Fe-Ni alloy and shadow masks prepared by applying piercing to the above shadow mask materials at the time of annealing the above shadow mask materials and the above shadow masks. CONSTITUTION:An ingot of an Fe-Ni alloy having a composition consisting of, by weight, 30-45% Ni and the balance Fe is forged, hot-rolled, and cold-rolled, and then, the resulting sheet is subjected to a repetition of annealing and cold rolling and the final cold rolling is performed until the prescribed sheet thickness is reached. The sheet is subjected to slitting to the prescribed width so as to be formed into a shadow mask material. This material is pierced by means of etching treatment and formed into a flat mask, and this mask is annealed in a nonoxidizing atmosphere and subjected to spherical forming by means of a press and further to blackening treatment, by which a shadow mask is produced. At the time of annealing the shadow mask materials and the flat masks in the above process, the value of surface roughness Rmax is regulated so that it has a positive value, by which the occurrence of mutual adhesion of plural shadow mask materials, etc., at the time of annealing and attendant reduction in yield can be prevented.

Next, the residual monomer is taken out by vacuum distillation involving forced transfer of the highly viscous copolymer. The highly viscous copolymer is dissolved in a mixture, of a 1-4 C alkanol with a solvent, which can dissolve a saponification product to prepare a homogeneous soln. Thereafter, an alkali agent is added to carry out saponification. If necessary, the solvent is removed from the soln. The highly viscous polymer as the residue is dissolved in a paint solvent, and the resultant copolymer soln. is filtered to the crosslinkable binder for paints.

Abstract: PURPOSE:To detect a failure by comparing the withstand voltage when a power source is turned off with the preset reference voltage of a voltage supply terminal. CONSTITUTION:When the double diffusion type MOS transistor DMOS 1 of an N-type channel fails due to the breakdown of a gate oxide film and the like, a current flows in a load 4 and the DMOS 1.

Filed: 1988-12-28
Abstract: PURPOSE:To eliminate the need for a power source by providing plural electronic image pickup means, and selecting either one of plural fixed focal points and plural electronic image pickup means by a focal distance provided on the means, respectively. CONSTITUTION:A switch 52 is controlled so as to select a CCD 12 when a microswitch 40 is turned off and to select a CCD 22 when it is turned on, respectively via a system controller 51. Thereby, an image pickup system 10 for wide when a (wide) mode is set, or an image pickup system 20 for telescope when a (telescope) mode is set is selected, respectively. Since a zoom function is realized by using a system by switching a mode in such a manner, it is not required to move a lens to vary the focal distance, which can eliminate a motor for zoom. Thereby, reliability and durability can be improved, and also, miniaturization, light weight, and low power consumption can be realized.

Title: Downshift gear change control device for automatic transmission
Inventor: SHINSO YOSHIHIDE
IPC: F16H61/10
Filed: 1991-12-17
Abstract: PURPOSE:To prohibit a downshift change to a lower gear for the use of a one-way clutch as a reaction brake in a high engine speed range where the engagement shock of the one-way clutch becomes a problem. CONSTITUTION:When the second gear selection pressure P2 is caused to occur with a controller 17 via a solenoid 17, a valve 11 raises the operation pressure PB of a band brake B/B, and a shock for transition from the first gear to the second gear is alleviated. Upon disappearance of the pressure P2, the pressure PB is quickly released through a non-return valve 16, thereby ensuring high response to a downshift change to the first gear. In this case, when engine speed Ne is high, a low one-way clutch acting as a reaction brake at the first gear generates an engagement shock. The controller 17, therefore, prohibits the disappearance of the pressure P2 and consequently a downshift change to the first gear.

Title: Agent for simply judging lime stone/dolomite and judging method
Inventor: OOKAMI TAKEAKI
IPC: G01N33/38
Filed: 1995-11-29
Abstract: PROBLEM TO BE SOLVED: To handle even a lime stone of a black color tone and quickly investigate a lime stone deposit,, by putting a mineral to be judged in a simple judging agent obtained by dissolving a specific amount of bromocresol green in dilute nitric acid and stirring the agent. SOLUTION: A simply judging agent is obtained by dissolving 0.03mol/l or more bromocresol green (pH eindicator) into 1.0mol/l or less dilute nitric acid. A mineral of lime stone or dolomite to be judged is put in the agent and stirred. The mineral is judged from a color change of the judging agent. Although an acid pH approaches to be neutral as the lime stone/dolomite is dissolved in the acid, a dissolving speed to the acid is different, between the lime stone and dolomite because of contents of MgO. Therefore, the lime stone/dolomite can be distinguished by measuring the time required for a color change of the pH indicator. The lime stone and dolomite can be distinguished outdoors simply and quickly without carrying a large quantity of dargerous strong acid, thereby improving efficiency for investigating a lime stone deposit.
