Title: Ignition timing control method
Inventor: AMANO MATSUO
IPC: F02P5/15
Filed: 1985-06-12
Abstract: PURPOSE:To make optimum ignition timing securable all the time under a driving state over a wide range of an engine, by detecting information inside a cylinder of the internal-combustion engine, while correcting the ignition timing on the basis of maximum combustion pressure inside the cylinder. CONSTITUTION:A cylinder internal pressure sensor 200 is replaced with a washer of a spark plug 52, clamping it tight to a cylinder head, whereby a minute strain appearing in this cylinder head by pressure inside the cylinder is detected, generating a detection signal WSS. With a processing circuit for this signal, interruption is applied to a central processing unit, leading a crank angle of an angle signal processing circuit, and a crank angle thetaR in maximum combustion occurrence from a reference point at that point that the interruption occurs is calculated. Then, a feedback value thetaF is calculated from this crank angle thetaR, setting the setting ignition timing thetaS upon calculation. With this constitution, since feedback control over the ignition timing takes place with the crank angle at that point the maximum combustion pressure occurs, it is always controllable to the optimum ignition timing.

Filed: 1988-05-24
Abstract: PURPOSE:To prevent change of properties of a lower thin film layer due to heat treatment in forming an upper thin film layer effectively, by performing the final heat treatment at steps for forming the upper thin film layer at the temperature condition which is sequentially lower than that in the final heat treatment in steps for forming the lower thin film layer. CONSTITUTION:The characteristics of a thin film which undergoes heat treatment at a specified temperature are hardly changed even if heat treatment is performed at a temperature lower than said temperature in the succeeding steps. When, various kinds of thin films 2, 3, 5-8 are sequentially laminated on a semiconductor substrate 1, the temperature at the final heat treatment in the steps for forming each of the thin films 2, 3, 5-8 is made lower than the temperature at the final heat treatment of the thin film which is lower than said film. In this way, the change of properties of the lower thin film due to the heat treatment for forming the upper thin film layer can be effectively prevented. Thus, a highly reliable semiconductor device is obtained.

Title: Spatial optical modulator having improved contrast ratio
Inventor: FLORENCE JAMES M
IPC: H04N5/74
Filed: 1998-05-08
Abstract: PROBLEM TO BE SOLVED: To reduce the diffraction of incident light on a projection optical system and to improve a contrast ratio by turning a support edge to be in parallel with a mirror edge and specifying an incident angle on both the support edge and the mirror edge. SOLUTION: This spatial optical modulator 70 is improved by providing each mirror 72 with a mirror support 74 fixing the support edge 76 turned at 45 deg. to all the incident beams of light generated by a light source 80. The edge 76 is parallel with the corresponding mirror edge T8 of the mirror 72 and the edge 78 is turned at 45 deg. to the incident beam of the light generated by the light source 80. The direction of the edge 76 to the incident light beam minimizes the diffraction of the light scattered to a dark field projection system optical system when a mirror surface is turned to an off-state.  By turning the edge 76 to be extended at 45 deg. to the incident beam of the light, the diffraction of the light is minimized and the formation of a diffrated light spot to the projection optical system is reduced and the diffraction of the light to the projection optical system from a corner is reduced.

Title: Method and apparatus for winding coil of stator of motor or the like
Inventor: RUCHIAANI SABATEIINI
IPC: H02K15/095
Filed: 1990-05-16
Abstract: PURPOSE: To enhance the density, matching and working efficiency of a winding by adjusting the reciprocal length of a needle through a stator and varying the vibratory phase at each end of the stator according to the reciprocation. CONSTITUTION: Neutral point 124 of each revolution due to vibration is obtained not simultaneously with reversion of the reciprocal direction shown at point 126 but after reversion. Consequently, a wire 102 has a trend to be deviated from a needle along a path shown at 130. Consequently, a wire being taken out from the stator end is shifted from a contact point Z to Y without touching a preceding wire while occupying the positions close to and remote from the stator end in the radial direction. Furthermore, a return stroke is started in front of the neutral point of vibration as the rotation due to vibration proceeds. Consequently, the wire rides on a previously wound wire and then it is pulled into an air gap 104 at a moment of time when the needle is returned with respect to the stator. According to the method, winding at the air gap is accelerated resulting in the enhancement of the density, matching and working efficiency of a winding.

Abstract: PURPOSE: To make it possible to easily control a refractive index distribution and to reduce a cost by drying a substrate coated with a polymer soln. of a polymer and liquid crystals while impressing an electric field perpendicular to the substrate plane, then stretching the substrate under heating, thereby forming a phase difference plate. CONSTITUTION: The phase difference plate 1 of a wide angle-of-view type consists of a laminate composed of a glass substrate 2 and a mixed layer 3 composed of the polymer and the liquid crystals. The process for producing such plate is executed by a preparing a polycarbonate soln. 5 prepd. by dissolving the polycarbonate and the liquid crystals into methylene chloride by a soln. casting method. Next, the surface of the glass substrate 2 is coated with the polycarbonate soln. 5 and a prescribed magnetic field is applied by an electromagnet 4 in the normal direction of the glass substrate 2 and the substrate is left at room temp. The glass substrate 2 is then dried by heating to obtain a film and the phase difference plate 1 is formed by stretching the film.  As a result, the variations in the phase differences are decreased and the dependency of the phase differences on angles is lessened. Further, the formation of the phase difference plate by a production line for uniaxial stretching is made possible.

Title: Loudspeaker telephone set
Inventor: KADOTA TAKAO
IPC: H04M1/60
Filed: 1990-05-16
Abstract: PURPOSE:To prevent malfunction of a variable attenuator control circuit due to the acoustic coupling between its speaker and its microphone by controlling a variable attenuator for only a voice signal in which the line side coupling is canceled. CONSTITUTION:A variable attenuator control circuit 12 receiving an output of an echo canceler 4 controls variable attenuators 3, 9. With a voice entered from a microphone 1 to the variable attenuator control circuit 12, since the control circuit 12 is made independent of the input from the microphone 1, the attenuation of the variable attenuator 3 is kept minimum and the voice is outputted from a voice output terminal 6 with a minimum attenuation. On the other hand, when the voice signal of an opposite party is inputted from a voice input terminal 7, the voice is sounded from a speaker 11 while the control circuit 12 increases the attenuation of the variable attenuator 3 and decreases the attenuation of the variable attenuator 9. In this case, a line echo due to coupling between the output terminal 6 and the input terminal 7 is canceled by the echo canceler 4.
