Patent JP-S62170923-A (JP)
Title: Focusing control method
Inventor: AMIKURA TAKASHI
IPC: G02B7/32
Filed: 1986-01-23
Abstract: PURPOSE:To easily control the driving of a motor by forming pulse width by counting up the number of signals synchronizing with spot light driving signals and controlling the pulse width of a driving source during the operation of a spot light projecting means. CONSTITUTION:A pulse signal SYNC synchronized with a pulse emitted from a light emitting diode 22 is applied to a synchronism detecting circuit 29 and a potential difference between a light non-emitting time and a light emitting time is outputted to the succeeding integrating circuit 30. When a mode is transferred to 'CLEAR' by a 'MODE' pulse, both the circuits 29, 30 do not generate any output and are initialized and infrared-ray driving also is not executed. The size relation between integrated outputs Va and Vb is latched until the mode is transferred to 'HOLD' mode again and a motor 50 is driven by pulse width control based upon a duty ratio through, a motor driving circuit 48, so that a photographing lens can be approached to the focusing direction. Thus, motor driving can be easily controlled.

Title: Slope protection component
Inventor: YABIKI HAJIME
IPC: E02D17/20
Filed: 1996-01-29
Abstract: PROBLEM TO BE SOLVED: To easily and definitely prevent vertical wires from falling away by cutting off the upper end portion of each vertical wire and projecting the upper end slightly upward from the horizontal wires on the uppermost stage and laying out an auxiliary horizontal wire engaged with each vertical wire from the opposite direction of this vertical wire. SOLUTION: Vertical wires 6 and horizontal wires 7, which are made of crimped steel wires and form a crest and a valley alternately, are crossed with each other and plain-woven in a rectangular shape, thereby forming a pair of net boards 2 which are laid out as opposed. Both net boards 2 are connected with a connection member 3. The upper end portion of each vertical wire 6 is cur and the upper end is projected slightly upward from a horizontal wire 7a on the upper most stage while a minimum required clearance (g) is secured in the lower part of the horizontal wire 7a on the upper 7a. An auxiliary horizontal wire 17 which is engaged with each vertical wire 6 from the opposite direction with this horizontal wire 7a is laid out.  The construction makes it possible to prevent easily and definitely the horizontal wire from the uppermost stage from falling away in the case when the upper end of each vertical wire is cut and protect even small-sized steel wire from being broken and secure adhesive properties between concrete and the steel wires to a satisfactory extent.

Title: Casting mold for precision casting and its production
Inventor: TAMURA JUNICHI
IPC: B22C9/04
Filed: 1998-01-06
Abstract: PROBLEM TO BE SOLVED: To impart the sufficient strength to counter a molten metal pressure at the time of casting to a casting mold and to eliminate the misrun in thin parts by welding a porous ceramic piece to an intermediate layer, thereby increasing the air permeability and strength to the casting mold. SOLUTION: The first layer which is an inner side among the layers constituting the casting mold 2 comes into direct contact with the molten metal and since there is a need for precisely transferring a product shape, a fine powder refractory slurry and stucco are used. The intermediate stage after the second layer is coated with the slurry and stucco and is dried, following which the porous ceramic piece 1 having the good air permeability is tightly adhered thereto and the next layer is executed. The porous ceramic piece 1 is preferably adhered to the place where the misrun occurs. The materials which do not differ much in thermal expansion are selected to meet the kinds of the refractories of the casting mold material. As a result, the strength enough to counter the surface pressure of the molten metal at the time of production may be imparted to the products, such as, for example, turbine blades, having the portions of large surface areas.

Title: Flow line switching means for ultrafiltration device
Inventor: KIMURA JIYUN
IPC: B01D65/02
Filed: 1981-02-02
Abstract: PURPOSE: To safely renew a flow line while avoiding an impact on a device, by switching a flow line for a new one with an automatic valve, and using an automatical pressure-control valve located at the inlet of the device and a control means to operate these valves.  
     CONSTITUTION: An automatic pressure-control valve 3 is located at the desired position of an inflow water line in an ultrafiltration device into which inflow water pretreated to a fixed extent and compressed at a fixed level is introduced. The automatic pressure-control valve 3 is set in an opened state during operation of the ultrafiltration device, e.g. water-collecting or backwashing, and in a closed state by fully opening all of flow line-change valves 4W10 at once when a command for change of state such as from water-collecting to backwashing or from backwashing to water-collecting is inputted. As a result, the pressure of the ultrafiltration system gradually falls, and useless impact would not be applied to the ultrafiltration device when the flow line-switch valve group 4W10 is  switched.

Title: Lubricating device for rolling bearing
Inventor: AKAGAMI KAZUO
IPC: F16C33/66
Filed: 1989-01-25
Abstract: PURPOSE:To enable continuous operation of a rolling bearing for a long period by pressuring the lubricating oil, which fills a cylindrical case which is provided in a cylindrical space between the outer surface of a shaft and the inner surface of a housing, by means of both a compression ring and a piston and sending the pressured oil to the bearing through small holes. CONSTITUTION:Lubricating oil 19, which fills a space 18 within a cylindrical case 16, is pressured by a piston 17, which is pushed by a compression spring 22, and leaches from small holes 20 and 21, which are made in both inner and outer peripheral surfaces of the case 16. The lubricating oil coming from the small hole 21 flows along an inner surface of a spacer 14 to lubricate a rolling bearing 1 from the side of an outer race 10. The lubricating oil coming from the small hole 20 lubricates the rolling bearing 1 from the side of an inner race 9 via a recessed groove 23 on an outer peripheral surface of the spacer 13. The quantity of the lubricating oil leached from the small holes 20 and 21 is small, while that of the lubricating oil within the space 18 is large in comparison with the former. Thus, by changing the sectional areas of the small holes 20 and 21, viscosity of the lubricating oil 19, and the resilient force of the compression spring 22, continuous operation of the rolling bearing can be conducted for a long period.
