Abstract: PURPOSE:To increase water resistance and stability, and simplify film coating by forming at least a part of a passivation film, by using a coat-baking film of silicon nitride system. CONSTITUTION:In the first place, on a silicon wafer 1 on which an aluminum wiring layer 2 is formed, liquid containing silicon nitride (SiNX) for forming a coat-baking film is spread at, e.g., 4000rpm for about 30sec by ordinary spin coating method. Thereby a coating film 31 of about 1mum thick is obtained. By heating, one time, this coating film at, e.g., 120 deg.C, alcohol system solvent is evaporated. Then heating at 250 deg.C is performed, and a network is formed by condensation polymerization reaction of silicon nitride dispersed in the liquid. Further, by heating at 400 deg.C or more and curing, a coat baking silicon nitride film 3 is obtained. Thereby, a passivation film of high water resistance comparable with a plasma CVD silicon nitride film can be formed by a very simple method with high mass-productivity.

IPC: B29L9/00
Filed: 1996-05-10
Abstract: PROBLEM TO BE SOLVED: To manufacture a foamed resin material enclosed product good in appearance quality. SOLUTION: A parison having a two-layered structure consisting of a solid layer 11 and a foaming layer 12 is subjected to a co-extrusion blow molding to form the outer frame of a sun visor. An injection port for a hard urethane raw soln. (d) for forming a core material is formed to the outer frame and the parison is set to the cavity of a product mold 30. At this time, the injection port is protruded from the insertion hole provided to the mold 30 to the outside. Whereupon, the foaming layer 12 is foamed by the heat of reaction of the hard urethane raw soln. (d). When the foaming layer 12 and the hard urethane raw soln. (d) are cured, both of them become a cushion material 16 and a core material 17 of the sun visor and the solid layer 11 covers both of them to become an exterior sheet 18.  Since the solid layer 11 and the foaming layer 12 are molded by co-extrusion, the resins of them are mutually bonded and not separated by a change with the elapse of lime and appearance quality is held to a good state.

Title: Screw-in-plunger type injection device and operation controlling method thereof
Inventor: MORITA RYOZO
IPC: B29C45/50
Filed: 1997-05-07
Abstract: PROBLEM TO BE SOLVED: To stably mold a product with excellent quality by a method wherein both the forward driving force and forward speed of an injection plunger are adjusted to become below pre-set limit values by passing the pre-set changing-over position at the forward driving of the injection plunger. SOLUTION: When an injection plunger 12 passes the pre-set changing-over position during the forward action of the injection plunger 12, the forward action of the injection plunger 12 is automatically performed at slow speed and by low pressure. As a result, the injection plunger 12 is brought into close contact at slow speed and low pressure with the tapered inner surface 18 of the injection cylinder 14. Thus, even under the condition that the accuracy of the dimensions of parts is not high, the dimensions of the parts change due to the thermal expansion of the parts and the like, the impactive abutment of the injection plunger 12 against the injection cylinder 14 is fully avoided and the favorable contact of the injection plunger 12 with the injection cylinder 14 is realized. Accordingly, this device has effects of heading off the thermal deterioration of a resin material due to the prevention of the resin material from entering between the injection plunger 12 and the injection cylinder 14 and the like.

Title: Beam alignment method in charged-particle beam device
Inventor: SASAKI ISAO
IPC: H01L21/027
Filed: 1986-05-23
Abstract: PURPOSE:To enable the position of a charged-particle beam to be searched in a time half or less compared with the case in a comentional spiral search method, by generating random numbers in a normal distribution where a maximum frequency exists at the center of the initial position and providing coordinate positions in accordance with the random numbers and then repeating this operation until a detected signal difference appears. CONSTITUTION:In case that Xn is expressed in Xn<<X1, Xn>>X2, that is, Xn exists outside of X1 and X2, the output difference can not be found by measuring in the vicinity of Xn, and therefore, the positions to be measured are determined in the following way; two uniform random numbersUPSILON1 and UPSILON2 are first generated between -1 and 1, and a normal random number M1 is then generated so that 30 (sigma=standard deviation) becomes + or -1 from UPSILON1 and UPSILON2. And, a coordinate position of Xn to be measured next is to be Xn+1=Xn+R.M1 (R=a maximum value in the variable range of X). When no output difference appears in a detector, a small range near Xn+1 is searched. Nevertheless, when the difference does not appear, M2 is moreover generated as X=Xn+R.M2. This operation is repeated until a detected signal difference appears. When the difference is found, M0 can be determined in accordance with a point P.

Abstract: PURPOSE:To attain the reaction control of a reactor with high accuracy by controlling the supply amount of a catalyzer to the reactor so that the difference between the temperatures at the input and output sides of a cooling jacket or the unit heating value is set at a prescribed level. CONSTITUTION:The temperatures detected by the input and output side temperature detectors 25 and 26 set at the input and output sides of a cooling jacket 24 are given to a temperature difference arithmetic part 27. Thus the difference of temperatures is obtained between the input and output sides of the jacket 24 and supplied to a temperature difference controller 28. The controller 28 calculates the deviation between the temperature difference signal delivered from the part 27 and the prescribed temperature difference value and supplies the temperature difference output accordant with said deviation to a catalyzer flow rate controller 29 as the supply target value of catalyzer. The controller 29 obtains the deviation between the target value sent from the controller 28 and the catalyzer flow rate detected by a catalyzer flow rate detector 30 and controls the supply amount of the catalyzer given to a reactor 21 via a control valve 31 so that said deviation is equal to zero. Furthermore the unit heating value is obtained from the temperature difference between both detectors 25 and 26 and can be controlled to the prescribed value.

Abstract: PURPOSE:To enable high-accuracy flow rate measurement free from span-error, by setting a threshold value of level detection in a supersonic wave pulse shaping part received as signal prior to having influenced by multiple reflections in a pipe line. CONSTITUTION:In order to remove the influence of multiple reflections, in No.1 or No.2 wave of supersonic wave prior to arrival of the multiple reflected waves, the reference for detection of level is set.
