Title: Mold for molding thread protector of steel pipe
Inventor: SUMINO HIROAKI
IPC: B29L1/00
Filed: 1989-10-14
Abstract: PURPOSE:To prevent the tip of an insert retaining pin from being cut at the taking of a molded item out of a mold by a constitution wherein a core mold consists of a center mold, the cross-section of which is polygonal and the outer side faces of which are tapered, and a plurality of peripheral molds, the inner face of each of which comes into sliding contact witch the outer side face of the center mold and on the whole outer face of which threading is performed. CONSTITUTION:Under the state that an insert member 6 is inserted in a cavity space, which consists of a cavity 7 and a core mold 1 or a center mold 2 and a plurality of peripheral molds 3, 3', 4 and 4', and retained with insert retaining pins 16, resin is injected in the cooling space G. At mold opening, the center mold 2 is retreated axially and, at the same time, the peripheral molds narrow towards the axis center. At that time, since the peripheral molds, on the outer periphery of which threaded part 5b is provided, are divided into a plurality of pieces the collapsible stroke of the core mold 1 becomes so large that the core mold can be narrowed deeper than the thread-depth of a molded item. As a result, the tips of a plurality of the insert retaining pins are retreated further inwards beyond the inner surface of the molded item. Accordingly, at the removal of the molded item, the tips of the insert retaining pins 16 can prevent from being cut.

Filed: 1995-09-22
Abstract: PROBLEM TO BE SOLVED: To provide an image forming device capable of exerting optimum fixing-temperature-control according to an output image which is printed. SOLUTION: Data on Y(yellow), M(magenta), C(cyan), and K(black), converted in a signal processing part 101, is once written in a FiFo memory 106, and before an output goes a laser driver 111, the presence of half tone density, that is, the presence of an image is judged for each line by means of a density detection part 108. Also, the data length of each lines is judged under address control exerted at the time of writing and reading into/from the FiFo memory 106 by means of an address counter 107. Further, the type of a recording medium and whether the image has one color or a plurality of colors are judged by a paper/color detector 110.

Title: Tunnel illumination control device
Inventor: ISHIZUKA TAKESHI
IPC: H05B37/02
Filed: 1992-10-07
Abstract: PURPOSE:To reduce the ratio of car accidents in tunnels by controlling the illuminances in the group of tunnels to the levels which best suit the external illuminance. CONSTITUTION:If any of a group of tunnels is in the morning turned on at the time (x), it is transmitted from the super-substation of the tunnel to a master station, and a CPU prepares an increment command and gives to the super- substations of the tunnels, and all tunnels are put into the same illuminated condition at one time. When the sun rises further and any tunnel gateway senses an illuminance over 200 lx, the tunnels are alike put into the same illuminated condition at one time. Then the sun set, the illuminance sinks, and any tunnel gateway senses an illuminance below 100 lx. but no illumination decrement takes place. If the CPU 32 receives the information that all tunnel applicable have become under 100 lx, decrement commands are given to all tunnels which are put in the identical illuminated condition. Even in case the night is launched and all-Off is introduced by the y-time setting, decrement command is sent to all tunnels when all are turned off, and they are put in the same illuminated condition at one time. This operating cycle is repeated everyday, and the ratio of car accidents is reduced.

Title: Slow cooling method and device for cavity unit
Inventor: FUKUSHIMA AKIRA
IPC: B29C33/04
Filed: 1991-09-20
Abstract: PURPOSE:To uniformize cooling speed of each section of a cavity unit by sending air from one or a plurality of directions for cooling at a slow cooling station when a plurality of cavity units, each of which comprises a pair of molds, are sent successively through a heating, filling.releasing, slow cooling, and product taking out station to perform molding. CONSTITUTION:A cavity unit 1 has a largest cooling speed at a temperature measuring point 3 near the undersurface thereof. Therefore, if air flow A is directed only in a direction (z), cooling speeds at temperature measuring points 1, 2 approach the cooling speed at the point 3. When an approximately circular optical element or the like is formed, since the distances from a mold 1 to a cavity are nearly equal in four directions, it is difficult to form a temperature distribution by air flows B, C. An air flow A may be added. In the case of forming a rectangular molded item on a x-y plane, if the air flows B, C are used, distances from sides of the mold 1 to a cavity are different, so that uniform slow cooling is not achieved. In this case, an air flow B or B and A are used to make slow cooling uniform as far as possible.

Title: Solenoid
Inventor: KUDO TAKUYA
IPC: F16K51/00
Filed: 1995-09-22
Abstract: PROBLEM TO BE SOLVED: To improve durability without making contaminants exist on a sliding part of a movable member by connecting a fixed member to a regulating mem ber in a passage. SOLUTION: Since a passage 25 for allowing external fluid on an object to be driven 4 side to flow to the part between a plunger 7 and a cap 9 is provided in a rod 10, a center post 8 and the plunger 7 are connected to each other by the passage 25. External control oil 26 is moved from the part A to the part B and the part B to the part C by the movement of the plunger 7. Since the control oil 26 of the part A on which large quantities of contaminants exist by friction of the object to be driven 4 is allowed to once flow to the part C by the flow through the passage 25 without passing the part B, the contaminants can not easily reach the part B. Accordingly, contaminants are not inserted on the sliding part of the plunger 7 to a bearing 22. Therefore, friction of the plunger 7 is decreased, and durability can be improved.
