Title: Digitization device
Inventor: TADAUCHI MITSUHARU
IPC: H04N1/403
Filed: 1980-06-27
Abstract: PURPOSE:To achieve digitization at a precise slicing level, by making a difference in timing between the writing of a digitized shading waveform in a memory and the reading of it. CONSTITUTION:A gate generating circuit 6 and an AND gate AND are added. The address timing when a signal with a shading waveform (b) is converted into a digital signal and stored in a memory 2 and its reading timing are varied according to a start pulse ST. Consequently, a shading waveform (b1) resproduced by an A/D reverse converting circuit 4 coincides with the original shading waveform (b) in terms of timing. This shading waveform (b1) is voltage-divided to generate a slicing level (c) and a comparing circuit 5 performs digitization. Thus, the precise slicing level is generated and accurate digitization is achieved.

Abstract: PURPOSE:To stably produce a wear resistant steel member excellent in breakage resistance by securing wear resistance, by imparting high hardness selectively to a required part and lowering the hardness of other base metal parts with annealing, in producing the wear resistant steel member. CONSTITUTION:In producing a wear resistant steel member excellent in breakage resistance such as a chisel, etc., for a hydraulic shovel of construction machinery, C content of the wear resistant steel as base stock is 0.80-1.20wt.%, it is subjected to spheroidizing so as to adjust its overall hardness to a relatively lower value of HRC20-30, preventing a micro crack breakage due to high hardness. Also, the wear resistant tip part requiring high hardness is subjected to high-frequency hardening to uniformly dispose cementite after subjected to machining to arrange the required shape, in order to adjust the hardness at HBC55-62 so as to improve wear resistance, thus the service life of the tip part is prolonged.

Title: Magnetic head
Inventor: SAITO SHIGEO
IPC: G11B5/60
Filed: 1985-04-23
Abstract: PURPOSE:To obtain a small and stable floating amount by providing a slit such as a groove on a floating surface by means of a floating head and a monolithic slider. CONSTITUTION:The drive and turn of a disk in a magnetic disk device try to float a floating head slider from the disk with the aid of a positive air pressure arising on the floating surface 1 of the monolithic slider. On the contrary, a negative air pressure generated by a groove part 2 returns the floating head slider to the disk surface. With this mutual action the floating head slider can maintain the small stable floating amount. Moreover a change in the floating amount can be eliminated with respect to the difference between relative speeds of inner and outer peripheries of the disk. Thus a uniform recording and reproduction can be available.

The sediment obtained from the above is heated to form an oxide-mixed powder. It is noted here that if the pH of the alkaline aqueous solution is less than 9, the sediments of lead hydroxide, titan hydroxide, and zirconium hydroxide will be redissolved. Accordingly, a highly uniform oxide of desired composition can be obtained.

Filed: 1986-04-16
Abstract: PURPOSE:To suppress an instantaneous electric power, to reduce the power source of a recording apparatus and to relieve the deterioration of the life of a thermal head, by driving two thermal heads arranged in close vicinity to each other by the same signals timewise shifted. CONSTITUTION:In performing printing, at first, a current is made to flow to a row of the heat generators 2a, 2b, 2c of a thermal head 1 on the basis of a driving signal 15 to generate heat therefrom and the ink held in the fine pores or fine recessed parts 9 of a film 8 is preheated. Next, the film 8 is sent by a film driving roll 10 so that the ink holding parts 9 are overlapped with a row of heat generators 3a, 3b, 3c. At this time, the heat generators 3a, 3b, 3c are supplied with a current on the basis of a drive signal 16 to generate heat. The generated heat further heats the preheated ink to generate bubbles in the ink and the ink is injected by the pressure of said bubbles to be adhered to paper 13. By applying the same drive signals timewise shifted to the thermal head, instantaneous power is suppressed and printing is performed at a high speed without deteriorating the life of the thermal head.
