Title: Soft - concrete using bituminous material
Inventor: KATO MAKI
IPC: C04B28/02
Filed: 1992-04-18
Abstract: PURPOSE:To obtain the soft concrete useful as a material for preventing a water-shielding sheet by compounding a solution comprising a cement, a sandy soil, an emulsifier and fibers with a highly water-absorbable polymer emulsion. CONSTITUTION:10-100kg of a cement, 50-200kg of a sandy soil, 50-500kg of an emulsifier, and 0-50kg of fibers are kneaded as the material for the solution A. 1-20Kg of a highly water-absorbable polymer emulsion is added as the material for the solution B to the solution A material and kneaded at the ordinary temperature. The materials A and B are applied by mixing and kneading each other and subsequently pouring the kneaded product into a mold frame, or directly applied as a solid kneaded product to the mold frame. Since the soft concrete holds the softness also after solidified, the soft concrete holds good flexibility even when used for protecting the water-shielding sheet and does not cause breakage on cracks of the sheet. When applied to sidewalks, etc., the soft concrete reduces the extent of the injury of a man when he falls down. The soft concrete gas further water-preventing effect because of its unlikeliness of causing cracks of the soft concrete by its temperature change.

Abstract: PURPOSE:To smooth the gain frequency characteristic of the entire amplifier by satisfactorily keeping the matching of signal input/output by connecting (n) ((n) is an arbitrary positive integer) pieces of thin film resistors and a 1/4 wavelength head open line to the output side of the high frequency amplifier parallelly with a signal line. CONSTITUTION:Between a second capacitor 10 and a signal output terminal 11, the (n) pieces of resistors 16, 18...21 and a head open line 22 to be a 1/4 wavelength at the lower limit of a used frequency band are installed parallelly to them. Thus, a resistance component is contributed on the low frequency side and an attenuation characteristic can be provided so as to be enlarged on the low frequency side. On the other hand, bonding pads 15, 17v20 are connected by any conductor such as a foil of gold and when the amount of the (n) pieces of resistors to be used is adjusted, the attenuation amount can be adjusted as well. Since the gain frequency characteristic of a single FET is canceled by adding the circuit provided with such an attenuation characteristic, the gain frequency characteristic of the entire amplifier can be smoothed.

Abstract: PURPOSE:To prevent the occurrence of bleeding and blurring in printing caused by the clogging of a screen plate with a printing paste by applying a fine vibration to the screen plate by a vibration generator. CONSTITUTION:A printing board 3 is positioned by a stage 5 and moved up to be disposed just under a screen plate 1.

The ultrasonic wave vibrators 6a, 6b can arbitrarily adjust or control the amount of ultrasonic wave in accordance with the viscosity of the printing paste 2, such as a cream solder, or the printing state of the printing paste 2 on the printing board 3. In this manner, the printing paste 2, such as a cream solder, can be prevented from adhering to the side walls of through-holes of the screen plate 1, and the clogging of the screen plate 1 can be minimized. Therefore, the occurrence of bleeding and blurring in printing can be minimized.

Title: Helical scan working device for lower cylinder of rotary head type magnetic recording and reproducing device
Inventor: OOTA ISAO
IPC: B23B5/00
Filed: 1985-07-02
Abstract: PURPOSE:To separate a lead part working cam plate from a holding chuck and to hold working accuracy at a required extremely high level at the high speed rotation of a main shaft by forming a synchronous pin for alternately engaging/disengaging the holding chuck and the lead cam plate. CONSTITUTION:At the time of low speed rotation of the main shaft 2, the holding chuck 3 fixed on the main shaft 2 and the rotatable lead cam plate 5 concentrically beared by the main shaft 2 are unitedly engaged with each other by the engaging/disengaging operation of the synchronous pin 10 so that the generation of a normal load to the main shaft 2 which may be generated by the rotation of the lead cam plate 5 is suppressed by the low speed rotation and high working accuracy is maintained. At the high speed rotation of the main shaft 2, the holding chuck 3 is separated from the lead cam plate 5 to interrupt the transmission of rotation to the lead cam plate 5 and rotate only the holding chuck 3 at a high speed. Thus, lathe work based upon high speed rotation can be attained while keeping the working accuracy without the generation of an abnormal load to the main shaft, and the working time can be shortened.

Abstract: PROBLEM TO BE SOLVED: To remove a damaged layer, without causing the irregularity on the surface of a semiconductor substrate by applying an accelerated oxygen ion beam on this surface through an opening of an insulation film on the sub strate surface. SOLUTION: Specified part of an insulation film 2 on the surface of a Si substrate 1 is selectively removed by photolithography and anisotropic dry etching using a gas of Cx Hy Fz +Ar to form contact holes with a damaged layer 3 on the surface of the openings of the substrate 1. Using an equilibrium flat plate type reactive ion etching apparatus, an oxygen plasma is produced in specified condition and accelerated oxygen ion beam 6 is applied on the damaged layer 3 to thereby utterly remove this layer 3. Thus a plane and smooth surface of the Si substrate 1 is formed, without causing a new damaged layer thereon.
