A method for determining a heating line for bending a steel plate includes the steps of: placing a virtual pattern on a virtual plate; rolling the plate along a frame line from a reference position to contact the plate at two points on the plate; rolling the steel plate back to the reference position; obtaining straight lines connecting the contact points; determining a heating point relative to a reference point; repeating the same steps while contacting the contact points on a reference point side; drawing straight lines from a certain heating point on a certain line to heating points on other lines; examining the degree of parallelism between each straight line and a roller line; grouping the relevant heating points as the same group; and connecting the heating points of the same group by a straight line or a curve.

Provided is a method for drying resin-used electronic parts which comprises enclosing resin-used electronic parts together with both an oxygen absorbent requiring no moisture for absorption of oxygen and a drying agent in a container having a gas barrier property and then sealing the container and removing oxygen and, preferably, then heating the sealed container. Thereby, no quality deterioration due to oxidation and degradation of a metal surface occurs in a drying step of resin-used electronic parts.

A raw material prepared by washing a phosphor powder containing a phosphor host material and an activator with an acid solution, followed by drying the washed powder, is heated within a thermal plasma at a temperature which permits partially melting the phosphor, followed by cooling and subsequently subjecting the resultant phosphor at 1200.degree. to 1700.degree. C., thereby manufacturing spherical phosphor particles having a concentration gradient in a radial direction.

A digital telephone set includes a digital telephone circuit and an emergency analog circuit. Normally, the digital telephone circuit is made active so that a handset provided in common therewith is connected to a digital transmission line. In an emergency, the emergency analog circuit is made active instead of the digital telephone circuit so that the handset is connected to an analog transmission line. A dial key pad unit and a speaker are provided in common with the digital telephone circuit and the emergency analog circuit.
摘要:
A vehicle anti-lock braking system having a master cylinder operated upon operation of a brake operating member, a wheel cylinder activated by a pressure produced by the master cylinder, and an anti-lock control device which includes a slip ratio detector for detecting a slip ratio of a drive wheel of the vehicle, and a pressure regulating device for controlling a pressure in the wheel cylinder, so as to maintain the slip ratio in an optimum range. The system also has a traction control device including a traction control power source, and a communication switching device for selective communication of the pressure regulating device with the traction control power source or the master cylinder. The switching device maintains a discharge port of the pressure regulating device in communication with a reservoir while the traction control power source is in communication with the pressure regulating device, and disconnects the discharge port from the reservoir while the master cylinder is in communication with the pressure regulating device.
摘要:
A sheet-like oxygen scavenger for preserving foods or other article in an oxygen-free conditions. This oxygen scavenger is composed of a mixture of fibrous material, iron powder, water and electrolytic material and formed into a sheet-like product by a process which is similar to a paper making process. This sheet-like oxygen scavenger may be covered with gas-permeable film or laminate film. A method of manufacturing the sheet-like oxygen scavenger is also disclosed.
