Title: Separating device of hollow molded product
Inventor: NAGAI TOMOMASU
IPC: B29C37/02
Filed: 1984-11-08
Abstract: PURPOSE:To contrive to carry out the cut and separation of a molded product continuously according to the displacement of a separating mold by providing the landing plunger mold capable of opening and closing to a holding mold opposite to the burr of a product. CONSTITUTION:Molded products are respectively discharged at the state where they are connected by burrs, directing their head to front side, and are successively supplied to a separating device 2. The device 2 is rotated in synchronization with a hollow molding machine 1, and the molded product 6 is kept at successively fitting in the holding frame of the holding mold 9a of a separating mold 9 in which a landing plunger mold is opened. When the mold 9b is closed according to the rotation of the device 2, the burr part 7 between the front end of the molded product 6 and the bottom of the product in a mold 9, is broken by a pushing up rod 14 and a pushing down rod 15. When the mold 9b is completely closed, the cut off blade 11b of the mold 9b is caused to be in pressure contact with the cut off blade holder 11a of the holding mold 9a, and the burr on the head of the molded product is cut off, thereby separating the molded product. Consequently, the molded product which is being discharged is effectively separated.

IPC: B60K5/12
Filed: 1993-08-25
Abstract: PURPOSE: To improve stopper strength and durability by forming integrally with the second metal fitting, a stopper part brought into contact with a stabilizer when a first metal fitting and a second metal fitting provided on the upper and lower sides of a vibration-proof base are subjected to bending deformation in their separating direction.

Title: Ultrasonic flaw detection apparatus
Inventor: MORITA NORITAKA
IPC: G01N29/04
Filed: 1987-09-18
Abstract: PURPOSE:To detect a flaw at a high speed with high sensitivity, by providing a partition plate made of an acrylic resin set to an angle range of 35-55 deg. with respect to the advance direction of ultrasonic beam and an ultrasonic wave absorbing material on the ultrasonic wave propagation route between an ultrasonic probe and a material to be inspected. CONSTITUTION:A partition plate 6 made of an acrylic resin having a uniform thickness is provided on the part of the acoustic coupling material 3 between a material 1 to be inspected and an ultrasonic probe 2 so as to be set to an angle range of theta=35-55 deg. with respect to the advance direction of ultrasonic beam 5. Herein, the beam 5 generated from the probe 2 is reflected by the partition plate but, with respect to the level of the reflected wave from the partition plate 6, the reflectivity thereof becomes about 10% or less within the angle range of theta=35-55 deg.. However, in high sensitivity flaw detection, the reflection level of the ultrasonic beam becomes a noise level not yet neglected to become a cause for lowering flaw detection capacity and, therefore, by providing an ultrasonic wave absorbing material 7 to the side surface where the ultrasonic beam reaches through the partition plate 6, the ultrasonic beam can be absorbed and attenuated to make high sensitivity flaw detection possible.

Title: Mobile communication system
Inventor: UCHIDA YOSHINORI
IPC: H04B7/26
Filed: 1991-09-13
Abstract: PURPOSE:To facilitate the change of the local oscillation frequency of a mobile station for omission of a high speed switching action of the frequency and to reduce the power consumption in a mobile communication system by interrupting the communication with an inter-one frame base station when the mobile station moves from a zone to another. CONSTITUTION:When a mobile station moves from a zone to another, the using frequency is used to the frame numbers (-3), (-2) and (-1) based on the frame count-down order. Then the communication is interrupted between the mobile station and two base stations in a no-transmission/reception frame of a frame number (0). The mobile station switches the frequency of a local oscillator for 5ms of the no-transmission/reception frame. As a result, the oscillation frequency of the local oscillator is easily changed with omission of a high speed switching action of the frequency and the power consumption is reduced when the mobile station moves from a zone to another.

Title: Manufacture of copper or copper alloy casting
Inventor: OSUMI KENJI
IPC: B22D21/00
Filed: 1984-11-08
Abstract: PURPOSE:To manufacture a copper or copper alloy casting which is free from a surface defect, without causing a sudden rise of a cost of a raw material by executing the casting by using a copper or copper alloy molten metal in which Ca is a low content percentage. CONSTITUTION:A copper or copper alloy casting which is free from a surface defect is obtained economically by casting a copper or copper alloy molten metal of 0.0002-0.015wt% Ca content percentage, which has been obtained by forming a molten raw material by mainly electrolytic copper and adjusting a compounding quantity of a scrap, or bringing Ca to a removing treatment by using a filtrating method, etc. by a filter at the state of melting. The reason why said Ca content percentage has been limited is because it is necessary to use the electrolytic copper only in order to set it to <0.0002%, a sudden rise of a cost is caused, and if it exceeds 0.015%, the generation rate of the surface defect increases.

IPC: F02P15/00
Filed: 1991-09-17
Abstract: PURPOSE:To prevent malfunction of a power switching element by high- efficiently emitting heat generated by an ignition device when the ignition device is incorporated in an ignition coil the temperature of which is increased. CONSTITUTION:A radiation fin 3 is arranged to an ignition coil with a built-in ignition device and in a place where radiation is intended to be made from a power switching element 2. The area of the radiation fin on the surface of the ignition coil is ensured to a value at which a temperature difference per a consumption power of 1 W between the air and the radiation fin is suppressed to 20 deg.C or less. Since a necessary minimum quantity of heat can be radiated from the radiation fin 3, this constitution prevents malfunction of the power switching element 2 and provides constantly stable operation.
