Title: Casting method of molten steel
Inventor: MIYAMURA HIROSHI
IPC: B22D7/00
Filed: 1983-03-25
Abstract: PURPOSE:To obtain a billet having high quality with less component segregation by solidifying the molten steel cast into a mold from the top surface of the molten steel as well while solidifying the same from the lower part and lowering the solidified shell on the top surface by following up to the shrinkage on solidification. CONSTITUTION:The ratio between the short side Lmm. and vertical thickness (t)mm. of a casting mold 1 is set at L/t>=2. A molten steel 3 is cast through a charging pipe 2 into the mold 1, and an adequate amt. of a heat insulating material 4 is added to the top surface of the steel 3 so that only the solidification from the base 1b of the mold 1 is progressed while suppressing the solidification from the top surface. The solidification from the top surface is permitted as well upon lapse of a suitable time. The solidification from the base 1b of the mold 1 precedes for a suitable time in the above-mentioned way, by which the generation of the shrinkage cavity on solidification is suppressed and the solidified shell of the top surface having a suitable thickness is formed. The descending of the solidified shell on the top surface is made easy by following up the shrinkage on solidification.

Inventor: NISHIHAMA NAOKI
IPC: A61C8/00
Filed: 1990-02-28
Abstract: PURPOSE:To improve the strength after embedment so that damage of a bone, etc., are scarcely generated by forming the outer peripheral surface of a shoulder part to a shape which adheres closely to a surface bone extending over almost the whole periphery, and forming the wall thickness of the lower part to a wedge-like cross section which is thinned gradually. CONSTITUTION:This implant 1 consists of a blade 2 whose width is wide and plural bar-like abutments 3, and on the upper part of the blade 2, a shoulder part 4 in the plane view longitudinal direction where a recessed part 6 is formed is formed integrally, and both left and right end recessed parts 5, 5 of the lower side are formed. The blade 2 is formed so that the wall thickness of the lower part from the shoulder part 4 is thinned gradually in a side view, and in a cross section vertical to the projecting direction of the abutment 3, the cross sectional area of the shoulder part 4 becomes the largest, comparing with other part. The outer peripheral surface of the shoulder part adheres closely to the inner wall surface of a groove 32 pierced in a surface bone 31 extending over almost the whole surface, and the cross sectional area of the shoulder part 4 exceeds the cross sectional area of the blade of the lower part, therefore, by piercing the groove of a shape and a dimension for which the shoulder part 4 is fitted, the blade can be inserted into the bone without a hindrance.

Abstract: PURPOSE:To obtain an electrophotographic method for high image quality with small-sized and simple constitution and an excellent electrophotographic device capable of complying with high speed processing by providing a fixed magnet inside an electrostatic latent image holding body and impressing AC voltage on an electrode in a cascade developing method. CONSTITUTION:The electrostatic latent image holding body 80 including the fixed magnet 81 is used, and developer is sprinkled over the holding body 80 on which an electrostatic latent image is formed so that it may be magnetically attached. Thereafter, the developer is carried and fed to an electrode roller part 87, and the developer at the non-image part of the holding body 80 is removed by electrostatic force and magnetic force by impressing AC bias on the electrode roller 87. When the developer is sprinkled over the holding body 80 first, developing is nearly finished. The electrode roller part 87 causes the developer to circulate in a developer accumulation 85 and recovers the developer at the non-image part of the electrostatic latent image. Thus, the irrgularity of a horizontal line and the splashing of the developer are prevented, and the image having uniform solidness, high resolution and high image quality is obtained.

Title: Semiconductor device
Inventor: SAKAGAMI TAKAKO
IPC: H03K5/08
Filed: 1990-03-02
Abstract: PURPOSE:To make it possible to normally drive the initial circuit even when Vcc and GND in a chip are changed by driving a threshold correcting circuit synchronously with an activation signal. CONSTITUTION:When a data out buffer driving signal OE to be an activation signal is turned to an 'H' level and the inverse of OE is turned to an 'L' level, a data-out buffer is activated and Vcc and GND potential are sharply changed. At that time, both transistors(TRs) Q2, Q3 are turned on and the threshold correcting circuit VVT is activated. Since a TR Q4 is turned off when an external input signal phiIN is an 'L' level input, the input level deciding threshold of the initial logical circuit INV1 is corrected to the increasing direction. Since the circuit VVT corrects the threshold of an input deciding level of the initial logical circuit, no error is generated in the input decision threshold of the initial logic circuit even when the Vcc and GND potential is varied.

Abstract: PURPOSE: To stabilize the winding of a wire rod by a simple device, by jointly using a dancer-roll taper tension control system changeing the tension of the wire rod by dancer-roll location signals and a wire rod winding control system changing the drive speed of a bobbin.  
     CONSTITUTION: When the winding diameters of a wire rod on a bobbin 18 increases and linear velocity becomes large, a movable roll 26 of a dancer-roll device 14 rises, and a dancer-roll location detector 42 emits location signals through a rotary means 28 to operate a speed change signal generator 54a. When a winding shape is disordered, the movable roll 26 is displaced, speed change signal generator 54a or 54b is worked and a non-stage transmission 22 is decelerated through a pilot motor 58. The tension of the wire rod is varied by changing the input currents of a power clutch 38 by means of a control means 60 in response to the displacement of the movable roll 26 in the dancer-roll revice 14. Thus, the winding of the wire rod can simply be stabilized.
