Title: Information signal recording and reproducing system
Inventor: MASHITA TSUGUAKI
IPC: G11B20/06
Filed: 1988-11-08
Abstract: PURPOSE:To prevent the distortion of the waveform of a reproduced information signal from occurring and to obtain interchangeability between recording and reproducing devices by varying the delay amount of either of 1st and 2nd reproduced dividing signals when a synthetic rectangular wave is deviated from 50% duty. CONSTITUTION:1st and 2nd dividing signals which are triggered at the rise and the fall of a rectangular wave obtained by shaping an FM modulation signal being an information signal so that the rectangular wave is 1/2 divided are recorded in a recording medium 19. Variable delay circuits 22 and 23 vary the delay amount of either of the 1st and the 2nd reproduced dividing signals reproduced from the recording medium 19 and delay them. A synthesis circuit 26 obtains the synthetic rectangular wave by performing the exclusive OR operation of both reproduced dividing signals and obtains the information signal after FM-modulating the synthetic rectangular wave. A control signal generation circuit 31 obtains a control signal for varying the delay amount of the variable delay circuits 22 and 23 according to the changing quantity of the synthetic rectangular wave when it is changed from 50% duty. Thus, the distortion of the waveform of the reproduced information signal is prevented from occurring and the interchangeability between the recording and reproducing devices is obtained.

Title: Aligner
Inventor: MAEDA SHIGENOBU
IPC: H01L21/30
Filed: 1991-09-30
Abstract: PURPOSE:To expose an image focussed on the whole rugged surface by a method wherein a mask is formed according to the data on a rugged shaped pattern on the surface of an element to be exposed as well as according to the data on the two-dimentional pattern to be projected on the surface of the element to be exposed. CONSTITUTION:The laser beams 1 emitted from a light source are halved by a half mirror 17a and one part of them passing through a lens 4a and a mask 18 in a hologram reaches a wafer 7. On the other hand, the other part reflected by another half mirror 17b and passing through another lens 4b also reaches the wafer 7. Next, these two beams interfering with each other on the wafer 7 expose an image focussed on the prospective whole rugged surface of the wafer 7. Through these procedures, said image is exposed using the mask 18 obtained by Fourier-transforming the data on the rugged shaped wafer 7 as well as the data on the two-dimentional pattern to be projected on the wafer 7 so that the projected pattern of the wafer 7 may be provided with the optimum focal length corresponding to the surface ruggedness thereby enabling any wafer even if having a large stepped part to be exposed focussing on the whole surface.

Abstract: PURPOSE:To excellently control the opening and closing position of an iris based on the accurate opening and closing position of the iris by automatically obtaining data for converting an output signal from a Hall element to the opening and closing position of the iris. CONSTITUTION:In the case of detecting the opening and closing position of the iris 22 equipped on a lens device 20 by the Hall element 23, the level of the output signal from the Hall element 23 at the time of detecting an output signal from an image pickup means 2 is taken as the data of the closing point of the iris 22. Then, the level of the output signal from the Hall element 23 at the time when the detection level of the output signal from the image pickup means 2 becomes maximum and is not changed is taken as the data of the opening point of the iris 22. The data for converting the output signal from the Hall element 23 to the opening and closing position of the iris 22 is obtained based on the data on the detected closing point and opening point. Thus, the data for converting the output signal therefrom to the opening and closing position of the iris 22 is automatically obtained and the accurate opening and closing position of the iris 22 is automatically detected without adjusting each lens device.

Title: Bipolar transistor and its manufacture
Inventor: MOHAMATSUDO MADEIHIAN
IPC: H01L29/737
Filed: 1987-11-09
Abstract: PURPOSE:To eliminate a need for an ion implantation process and a complicated process accompanied by the process and to freely regulate an intrinsic region by a method wherein an insulator layer provided to be adjacent to individual active layers is contained and an extraction electrode of an emitter layer and a collector layer is extended and formed on the insulator layer. CONSTITUTION:In an emitter-top HBT where a collector layer 2 composed of n-GaAs, a base layer 3 composed of p-GaAs and an emitter layer 4 composed of n-AlGaAs have been formed on a semiinsulating GaAs substrate 1, an emitter extraction electrode is provided in such a way that it is to be adjacent to an intrinsic region and that it is extended on an SiO2 layer 8 as an insulator formed selectively on the semiinsulating substrate. That is to say, because an emitterbase junction does not exist in a part other than the intrinsic region, a parasitic capacitance value is small and a high-speed high-frequency characteristic is improved. In addition, because an active layer can be laminated in a region partitioned by the insulator layer on the semiinsulating substrate by a selective epitaxial method, an ion implantation process and a complicated process accompanied by the process are not required.

Title: Auxiliary tool for playing stringed instrument like chinese fiddle
Inventor: YAZAWA SUMIKO
IPC: G10D3/18
Filed: 1998-09-19
Abstract: PROBLEM TO BE SOLVED: To securely hold the core tip part on the knee and so as not to give damage to clothing, etc., by providing a winding part which can be held on the knee and a reception part which is provided thereupon and where the core tip part is supportably constituted. SOLUTION: A reception part 3 is nearly rectangular cloth, etc., and has an opening part 6 at one end and the other end is stitched to a winding part 2. Consequently, the core tip of a Chinese fiddle can be inserted into the reception part 3 from the opening part 6 and held. The reception part 3 has an opening part 10 smaller than the opening part 6 of a reception part 4 and the sizes of the opening parts of the reception parts can be selected according to the operability of a player and the shape of the core tip. When the Chinese- fiddle-like musical instrument is used on the knee, since the tip core is rotatable or supported rotatably at a fixed position through the reception part 3 and winding part 2, intentional operation for fixing the core tip is not necessary during the performance.  Consequently, the player can concentrate on the performance and a wrong string is never selected due to unexpected movement of the core tip.
