Abstract: PURPOSE:To increase the etching rate for an underlayer resist layer to improve a throughput by dividing the underlayer resist into two layers, by applying PMMA to the first layer and then baking the first layer, and by applying a resist including a dyestuff absorbing an exposure wavelength to the second layer and baking the second layer. CONSTITUTION:A first resist layer 2' mainly composed of PMMA is applied onto a stepped substrate 1, until the resist top surface becomes flat, and baked thereafter. Then, a second resist layer 3' with a small etching rate including a dyestuff absorbing an exposure wavelength is applied, until is thickness has masking properties for etching of the stepped substrate 1 and baked thereafter, further SOG4' is applied and baked thereafter, and a resist 5' having high definition is thinly applied thereon and baked. The resist 5' is exposed and developed for the applied resist so that a pattern is formed Then, plasma etching is conducted for SOG4' by the use of resist 5' as a mask, and finally etching is conducted for the stepped substrate 1 by means of respective resist layers 2', 3' as masks.

Title: Magnetic measuring method
Inventor: INOUE KIYOSHI
IPC: G01D5/245
Filed: 1992-03-03
Abstract: PURPOSE:To obtain a method enabling magnetic measurement by its direct application to an optional object to be measured. CONSTITUTION:According to this magnetic measuring method, the magnetic scale is read by a magnetic head set confronting to the scale, thereby to measure the relative movement of the scale and the head. A surface treatment part 3a is directly partially formed on an object 3 to be measured in a direction of the relative movement so as to improve the magnetic characteristics. The magnetic scale is obtained by magnetizing and recording the surface treatment part. The magnetic scale directly recorded on the object is read by the magnetic head 1. As for the surface treatment to improve the magnetic characteristics, the part 3a may be nitrified, carbonized, turned to boron or iron or a rare earth, or subjected to a combined treatment of the above processes. Moreover, as for the means for the surface treatment, laser or discharge/deposition process may be utilized. It is also recommended that the surface treatment is conducted in the magnetic field to record the magnetic scale.

Title: Calculation of amplitude of ac
Inventor: FUJII SHIGEO
IPC: G01R19/04
Filed: 1984-03-12
Abstract: PURPOSE:To make it possible to measure amplitude square value receiving no variation in frequency with high accuracy, by substituting current and voltage, which are sampled from AC at a predetermined cycle and continuing mutually, for a predetermined operation formula. CONSTITUTION:There is relation of Ai.Bi-1-Bi.Ai-1=Ap.Bp sinphi.sinthetaK be tween current data Ai, Ai-1 and voltage data Bi, Bi-1 (wherein theta is phase difference of a current and voltage), which are sampled from a power system at a predetermined cylce and respectively set at 90 deg. intervals, a current peak value Ap and a voltate peak value Bp. In this formula, when curent data are delayed at every one step and Ai Ai-1, Ai-1<Ai-2 and phi=thetaK are set and, further, Ai= Bi is set to fix a phase, a formula Ai-1<2>-Ai.Ai-2=A<2>p.sin<2>(thetaK) is obtained. This formula imparts an amplitude square value reduced in a frequency error.

Title: Digital loop filter
Inventor: TSUNOISHI MITSUO
IPC: H03L7/099
Filed: 1992-03-03
Abstract: PURPOSE:To provide a digital phase locked loop(DPLL) circuit with a small jitter and a wide range of frequency deviation that can respond by using phase control information from a digital loop filter. CONSTITUTION:Only a random period loop filter part 1 generates a phase control pulse (periodical DPLL control pulse) from an adder 3 at the initial stage, however, a constant period loop filter part 2 also generates the phase control pulse after the lapse of a certain time when frequency deviation is detected. Since the period of the periodical DPLL control pulse in such a case is inversely proportional to the frequency deviation, the periodical DPLL control pulse is generated at shorter intervals in inverse proportion with the frequency deviation with the lapse of time. In such a way, a stationary state is set while approaching the fundamental clock of a subscriber side device (NT) after DPLL control. Meanwhile, when the frequency deviation is small, the period interval of the periodical DPLL control pulse is widened, therefore, phase comparison information can be balanced.

Title: Production of corrugated board adhesive used in high-speed corrugator
Inventor: MIYAKE KANICHI
IPC: B32B29/08
Filed: 1979-04-16
Abstract: PURPOSE: To produce an adhesive suited for high-speed bonding and used in high- speed corrugators, by using, as the main starch used in the adhesive, a starch having a gel strength at gelation in a specific range.  
     CONSTITUTION: In a process for producing a corrugated board adhesive according to a Steinhall method, a crosslinked subterranean starch having a gel strength at gelation, of 1.5W4.0kg, when measured with a texturometer, is used as the main starch. The measurement of the gel strength is conducted using a texturometer under the conditions: plunger diameter 13mm round type, platform large cup, clearance 3.0mm, voltage 2V. With respect to the degree of crosslinking of the startch, a low degree results in insufficient gel strength a gelation, whereas a too high degree results in the decrease in the water retention of the starch with the consequent decrease in the water absorptivity of the adhesive, and also in the rise in the gelation temperature. Therefore, these starches are not usable as the main starch used in the corrugated board adhesive.

Filed: 1988-02-29
Abstract: PURPOSE:To relieve a drop in idling speed by making a duty ratio larger when a pulse space has come to larger than the last mean pulse space, in a device which controls an electric control type vacuum selector valve for its duty. CONSTITUTION:A control part 60 calculates a mean pulse space at the time of idling speed of an engine 4 and stores it in memory, and when the pulse space afterward has come to larger than the last mean pulse space, a duty ratio in an electric control type vacuum sector valve 52 is controlled. When a current consumer acts at the time of idling speed, engine speed is suddenly dropped, and a pulse space in the idling speed has come to be larger than the mean pulse space because of a drop in the idling speed, the duty ratio of the electric control type vacuum selector valve 52 is made larger. With this duty ratio, the electric control type vacuum selector valve 52 is opened, opening an idle stabilizing compensation circuit 50, and an air quantity for the engine 4 passing through the selector valve 52 is increased and the idling speed is made to go up, thus a drop in the idling speed is relieved.

Abstract: PURPOSE:To reduce the outer diameter of a solderless ball bonded portion at the end of a capillary body, to prevent an accident of contacting with other electrode and to improve the quality thereof and productivity of a bonding capillary by reducing the diameter of the solderless ball bonded portion smaller than that of the ball at the end of a wire. CONSTITUTION:A hole 32 for passing an AU wire is perforated at a capillarly body 31 in central direction, and a tapered corner 33 is formed at the end of the hole 32 of the capillary body 31. Further, the tapered angle theta on the outer periphery of the capillary body 31 is formed acutely so that an Au ball 41 may not be solderlessly bonded on the outer periphery. The Au wire 42 is solderlessly bonded through the ball 41 onto a semiconductor pellet 43. In this case, the diameter T at the end of the capillary is formed smaller than that OD of the ball 41. Thus, the ball 41 is upwardly escaped without being solderlessly bonded at the end of the capillary on the outer peripheral side thereof to form an annular projection 44 therearound.
