Title: Solenoid valve
Inventor: TAKAYAMA TOSHIO
IPC: F16K31/06
Filed: 1998-09-30
Abstract: PROBLEM TO BE SOLVED: To provide a compact solenoid valve capable of reducing required current. SOLUTION: When electromagnetic force of a solenoid mechanism 9 is made a first prescribed value, this valve is constituted so that a first valve element 5 may be opened against a difference of energizing force of a first and second springs 8 and so that a second valve element 6 may be closed by energizing force of the second spring 8. Also when electromagnetic force of the solenoid mechanism 9 is made the first prescribed value and a hydraulic holding mode is obtained, for instance, only electromagnetic force of a size against a difference of energizing force of the first and second springs 7, 8 is required to be generated. As compared with electromagnetic force against the total of energizing force of the two springs required in a conventional technique, electromagnetic force to be generated is only required to be small.  By the small electromagnetic force, current flowing in a coil can be reduced, the number of winding of the coil can be reduced, and thereby the device can be made compact and arrangement space can be reduced by making the shape of the coil small, and capacity of a battery can be reduced.

Title: Resist composition and pattern forming method
Inventor: WATANABE FUMITAKE
IPC: G03F7/11
Filed: 1985-12-09
Abstract: PURPOSE:To strengthen a dry etching durability of the resist composition by comprising a specific styrene polymer into the titled composition. CONSTITUTION:The titled resist composition comprises the styrene polymer shown by the formula. Said styrene polymer is composed of a monomer contg. a chloromethyl group and a monomer contg. a silicon atom. The chloromethyl group has an effect of giving sensitivity to the resist, when the styrene polymer is used for the resist. The more the chloromethyl group is contained in the styrene polymer, the higher sensitivity of the resist composition is obtd. The introduction of the chloromethyl group into the styrene polymer depresses the dry etching durability. As the higher the content of the chloromethyl group is, the more the effect of increasing the sensitivity reduces remarkably, the value of (m)/(n+m) is preferably 0.01-0.2. Thus, the titled composition shows sufficiently the durability as a mask, when a thick org. high polymer layer is etched, and the transfer of the pattern to the org. high polymer layer is effected with a high accuracy.

Title: Measurement of impurity concentration
Inventor: ONO HARUHIKO
IPC: G01N1/32
Filed: 1985-12-09
Abstract: PURPOSE:To enable an approximate value of specific impurity concentration to be rapidly determined, by comparing shapes of transfer etching pits, which are formed by etching on a semiconductor crystal substrate, with reference data determined in advance.

In particular, transfer etching pits formed by the proper etching liquid on a semiconductor crystal substrate has respective shapes peculiar to crystal kinds, substrate orientation, and etching liquid, varying with concentration of impurity contained in the crystal. Therefore, an approximate value of specific impurity contained in the crystal can be determined by observing and identifying shapes of the transfer etching pits.

The remaining oxide film 4 is eliminated thereafter and the undercoat of polysilicon 3 is etched using the tungsten 5 as a mask. For instance, the oxide film 4 is deposited thicker than the tungsten film deposited later, and a part of the oxide film 4 which becomes the patterning section for tungsten and polysilicon later on is eliminated to form an etching area 100. The tungsten 5 is selectively deposited only onto the polysilicon 3 by use of the selective CVD method.

Filed: 1995-10-26
Abstract: PROBLEM TO BE SOLVED: To restrain delamination after baking by preventing an inner electrode and a ceramic layer from peeling due to decomposition gas by making decomposition temperature of binder contained in each of a first member and a second member of a paste film and a ceramic green sheet different from each other. SOLUTION: A decomposition temperature of a first binder contained in a thin first member of a paste film and a ceramic green sheet is set higher (20 deg.C or more) than a decomposition temperature of a second binder contained in a thick second member. Therefore, in a debinder process, a second binder contained in a second member is decomposed first. Decomposition gas generated by the decomposition passes through a second member and is discharged relatively readily. Then, a first binder contained in a first member is decomposed. The decomposition gas is relatively readily discharged passing through a second member which is porous due to decomposition of a second binder.
