Title: Vertical grinder
Inventor: TAKEYA KUNIO
IPC: B02C15/04
Filed: 1990-11-02
Abstract: PURPOSE:To hold the inner surface of a raw material charging chute in a clean state by preventing the adhesion of a raw material to the inner surface of the chute by forming the rotary shaft of a separator from a hollow pipe and connecting the upper end of the rotary shaft to a raw material supply pipe by a thrust bearing and using the rotary shaft as the raw material charging chute. CONSTITUTION:A raw material charging chute 17 is connected to a fixed non-rotary raw material supply pipe 50 by a thrust bearing 60 and can be freely rotated by the rotation of a separator 13. When the wt. of the separator 13 is large and the load of the bearing 13B of the separator 13 is desired to be reduced, the lower flange of the raw material supply pipe 50 is loaded with the thrust bearing 60 to suspend the upper flange of the raw material charging chute from the upper surface of the thrust bearing 60. Since a raw material is charged from the raw material charging chute rotated with the operation of the separator during the operation of a mill, the raw material is hard to adhere to the inner surface of the raw material charging chute and, even if the raw material adheres to the inner surface, it is easily removed from the inner surface of the chute by centrifugal force and, therefore, the inner surface of the chute 18 kept in a clean state.

Title: Optical device
Inventor: YOSHITAKE HIROSHI
IPC: G02B7/09
Filed: 1985-12-25
Abstract: PURPOSE:To prevent a collision of an objective lens and an object to be observed, and a damage caused thereby, by inhibiting an automatic focusing function, when an observation point is in the outside of an automatic focusing range. CONSTITUTION:A microprocessor 48 decides whether the next observation point is within an automatic focusing range or not, by comparing a calculated distance D and a radius R of the automatic focusing range. The microprocessor 48 resets a flag F, and inhibits an automatic focusing function. In this way, since the automatic focusing function is inhibited, it does not occur that the tip part of an objective lens 26 is moved to a lower position than a wafer surface, due to a fact that a focus of the objective lens 26 is aligned to a chuck surface of the outside of a wafer 12. In this way, when moving to an observation point within the automatic focusing range, a collision of the tip part of the objective lens 26 and the end of the wafer 12 does not occur.

Title: Coating of ceramic covering layer
Inventor: ONO MASAYOSHI
IPC: C04B41/50
Filed: 1989-11-15
Abstract: PURPOSE:To reduce the cost by forming a coating layer of ceramics on the surface of a substrate, sending DC, AC or microwave electric current, heating the coating layer of a ceramics by self-resistant heat generation and bonding the layer to the substrate. CONSTITUTION:A coating layer 12 of ceramics such as glass frit powder is formed on the surface of a substrate 11 such as ALC concrete, placed on a conveyor 17 and transported in the longer direction thereof. Then an operation order signal is given to a control device 22, an electric current is sent through a current-carrying control part 14 to a heater 25 to heat the coating layer 12 of ceramics. Simultaneously electric voltage is impressed to electrodes 13 in contact with both sides of the coating layer 12. When an electric resistance value of the heated coating layer 12 is reduced and an electric current is sent between the electrodes 13, the coating layer 12 is heated by self resistant heat generation and then melted. On the other hand, when an electric current is sent to the coating layer 12, an electric current value is subjected to feedback to the control device 22 by the current-carrying control part 14 and reaches a given value, current carrying to the heater 25 is stopped. Consequently, molten part of the coating layer 12 is naturally cooled, hardened and bonded to the surface of the substrate 11.

In such a way, a substrate can be manufactured. Since the board is obtained by cutting the insulating material containing buried linear conductors, complicated processes for driving the insulating material and making plating, etc., for providing the conductors becomes unnecessary. In addition, the cutting of the insulating material containing the buried conductors can be performed easily by utilizing the cutting method of glass, etc., as it is. The insulating material can be cut in a direction which is substantially perpendicular to the conductors and, when required, in another direction which is not perpendicular to the conductors.

Abstract: PURPOSE:To prevent the generation of a pseudo gap by making a core thickness on a recording medium sliding surface approximately equal to a track width and extending a magnetic thin metallic film up to the side surface part of a head core part at least near a magnetic gap. CONSTITUTION:For head core parts 9 and 10, track width regulating grooves 12a and 12b are formed so that a core thickness on a recording medium sliding surface 11 can be the same width as a track width W and a magnetic thin metallic film 14 is extended up to side surface parts 9a and 9b of track width regulating grooves 12a and 12b of the core part 9 near a magnetic gap 8. Consequently, the interface edge part of the head core part 9 and the film 14 is not directly brought into contact with a glass 16. Consequently, both edge parts K1 and K2 of an interface K of a magnetic gap part 14a and the head core part 9 which are filmed in parallel to the magnetic gap 8 are covered with side surface films 14b and 14c of the magnetic metallic film and not brought into contact with the glass 16. Thus, the component of the glass 16 is not permeated to the interface K, a response layer is not formed and the pseudo gap generation is prevented.
