Filed: 1994-10-20
Abstract: PURPOSE: To cope with two-way printing with two printing heads by a method wherein two recessed parts for printing head are provided so that a thermal transfer ink ribbon may pass in order in taking up. CONSTITUTION: A recessed part 5 for a first printing head 15 for inserting the first printing head 15 of a thermal transfer printer and a recessed part 6 for a second printing head 16 for inserting the second printing head 16 are provided to a cassette. When a thermal transfer ink ribbon 3 is fitted to the thermal transfer printer, the first printing head 15 of the thermal transfer printer is inserted into the recessed part 5 for the first printing head, and the second printing head 15 is inserted into the recessed part 6 for second printing head. After setting paper, printing in a regular direction from a line top is carried out with the first printing head 15.

Title: Root canal operating apparatus
Inventor: KAWAI AKIRA
IPC: A61C5/02
Filed: 1991-09-06
Abstract: PURPOSE:To facilitate the driving and stoppage of a reamer or the like in the expansion of a root canal by using a cutting needle mounted on a head as root canal length detection electrode needle to stop the driving of the cutting needle when the detection electrode needle reaches the point of a root. CONSTITUTION:When a hollow part of a circular member is inserted into a head case part 44 and turned, an electrode needle part 52a of an electrode integrated with the circular member contacts a reamer or a file 45. When the tip of the reamer or the file 45 reaches the position of a root point, a current flowing therethrough gives a specified fixed value and a pointer of a detector 60 indicates an APEX position, telling that the tip of the reamer or the file reaches the position of the root point. Therefore, here, the driving of ultrasonic vibration or a microengine is stopped and once returned from the point of the roof point, the reamer and the file are driven again to continue due operation. This enables operation of a root canal safe with better handling.

IPC: G11B7/09
Filed: 1991-10-03
Abstract: PURPOSE:To provide a compact and light movable part without useless resonance in the objective lens driving device constituting an optical pickup. CONSTITUTION:With regard to the disposition of a tracking coil 24 composed of printed coils of >=two layers, a gap between one pair of coils formed in each layer is disposed not to be overlapped with a gap between one pair of coils in the other layer or other each individual layer. Each printed coil is reinforced in the vicinity of its center by a conductor (copper foil) forming the coil, and hence mechanical strength of the printed coil itself is promoted. Since the tracking coil 24 is utilized for a reinforcement member for a lens holder 22 as a movable part, the objective lens driving device without useless resonance even in the compact and light movable part can thus be realized.

Title: Multi-path detector
Inventor: NAKAMURA TETSUO
IPC: H04B17/00
Filed: 1990-09-26
Abstract: PURPOSE:To detect a multi-path properly by providing a threshold level increasing means to the detector. CONSTITUTION:The detector is provided with an electric field level detection means 8 detecting an electric field level of a broadcast radio wave, a threshold detection means 9 detecting a threshold lower than the electric field level, and a threshold level increasing means increasing the threshold to be detected in response to the electric field level in a range lower than the electric field level. That is, a detection terminal 9 is provided between a resistor R2 and a base of a transistor(TR) 2. In this case, when the threshold detection means 9 detects a threshold V2 lower than the electric field level V1 by the electric field level detection means 8, the threshold increasing means increases the threshold V2 to be detected in response to the electric field level V1 within a range lower than the electric field level V1. As the electric field level V1 increases, even when the threshold V2 with respect to a prescribed AM modulation is larger, the electric level follows to the threshold level V2. Thus, a proper multi-path level is detected in response to each electric field level V1.

Title: Dry etching of semiconductor
Inventor: SOGA HAJIME
IPC: C23F4/00
Filed: 1997-09-05
Abstract: PROBLEM TO BE SOLVED: To improve a product yield by preventing formation of black silicon. SOLUTION: Predetermined amounts of gases of HBr, SF6 , SiF4 and HeO2 are introduced into an etching chamber, a single sheet of substrates is etched and removed from the chamber, and a cleaning-exclusive dummy substrate having an SiO2 layer formed on an Si substrate is placed in place of the etched substrate to carry out a single-wafer cleaning step CL1. The step CL1 includes a cleaning step C1 for 80 seconds, a seasoning step S1 for 20 seconds, and a purge step P1 for 60 seconds. In the step C1, a reaction product adhered onto walls of the etching chamber is removed by etching using the SF6 gas. In the step S1, the atmosphere and substrate temperature are adjusted to remove the reaction product by etching in the step C1.  In the step P1, the gases are made to flow in such a condition as not to generate a gas plasma, thereby removing foreign matter remaining as floating in the etching chamber after the step S1. As a result, a predetermined trench shape can be obtained without forming black silicon, and a product yield can be improved.

IPC: H04N1/113
Filed: 1986-10-29
Abstract: PURPOSE:To reduce deviation of dots as a whole, by performing picture recording by using dot recording clock signals, whose phases are deviated in the direction in which dot deviation caused by an error can be reduced, by a time which is about half of the rotational error time found on each face of a polygon mirror.

Therefore, dot deviation caused by the rotational error of the polygon mirror 8 can be reduced easily with a simple constitution without providing a grating and synchronism controlling circuit and, moreover, without using any polygon mirror having extremely high accuracy.
