IPC: C21D7/04
Filed: 1983-07-20
Abstract: PURPOSE:To eliminate the need for increasing the thickness in the shoulder part of a pin and to reduce the weight of a crank shaft by making the pressurizing force on fillets by rollers stronger on the crank journal side and weaker on the top end side of the crank arm. CONSTITUTION:A pressure control valve 9 is interposed in the fluid pressure circuit of a cylinder 6 connected via a forward-backward change-over valve 8 to a fluid pressure source 7 in the stage of working by rooling. The valve 9 is controlled by the signal from a phase detector 10 provided to a driven work holder 2. The fluid pressure inputted to a cylinder 6, i.e., the pressurizing force on each fillet (wc) by each roller 4 is adjusted and changed so as to be made stronger in the circumferential surface part of each fillet (wc) on the crank journal (wa) side and to be made weaker in the circumferential surface part on the top end side of the crank arm (wd). The part of the fillet (wc) of the crank shaft (w) on the crank journal (wa) side is thus substantially strengthened.

IPC: B60T8/171
Filed: 1983-07-18
Abstract: PURPOSE:To select the optimum directivity independently of the strength of a received radio wave by providing a means switching the antenna directivity until a noise in a composite video signal of a television receiver is coincident with the minimum value of the noise set initially. CONSTITUTION:A minimum noise voltage at the 1st round of the directivity switching is stored in a storage circuit 10.

Title: Photosensitive resin plate material
Inventor: UMEDA YASUSHI
IPC: G03F7/004
Filed: 1986-06-06
Abstract: PURPOSE:To permit exposure of a negative and plate material without using a vacuum device and the easy discrimination of a latent image by naked eyes in the exposing stage by using a photosensitive resin layer contg. a dye which is faded in color by active radiations and form the color again in the developing stage and having surface tackiness. CONSTITUTION:This plate material consists of a base, the photosensitive layer and film-like protective layer. The photosensitive layer is formed by uniformly compounding the dye which is faded in color by the active radiations in UV to visible parts and forms the color again in the developing stage with a compsn. consisting of a polymer having rubber elasticity, addition polymerizable unsatd. monomer and photopolym. initiator. The dye which is incorporated into the photosensitive layer and is faded in color by the radiations of the UV to visible parts is colored again when treated with a developer. The exposed part is colored again in the eluting stage by the developer; therefore, the development is substantially controlled and executed even with the image contg. fine dot or lines. The removal of such dots or lines by brushing during the development is averted and the exposed part is faithful to the original picture. The printing plate having the shoulder-shaped excellent relief image is thus obtd.

When the process inspection items to be inspected are selected with a keyboard 7, the automatic execution data are read out of the automatic- execution-data file of the floppy disk and stored into the RAM 3. Each step inspection is performed based on the data. When manual execution is selected, the process inspection menu is read out of the floppy disk and displayed on the display screen, and the key-input standby is set in each step. Then, the inspection is conducted. The operator needs not perform any operation until the manual key-input standby is set and can monitor other device for that period at the same time.

Abstract: PURPOSE:To prevent an internal surface from wearing, and also to realize a speed change gear lightweight and lowpriced on the whole by forming a sliding contact part of a material high in resistance towear on the internal surface of a shifter catch groove at a fork end made of aluminum etc. CONSTITUTION:To internal surfaces of shifter catch grooves 37b-40b formed respectively at fork ends 37a-40a provided in parallel, strip-shaped member made of polyamide-based resin or a metal high in resistance to wear are bonded in a channel shape as shown in the figure to form sliding contact parts 37c-40c. Therefore, even if a shifter, especially, a pawl body 41b tip would slide in pressure contact with engaged grooves 38b (37b, 39b or 40b) at the fork end of this constitution in selection or shift operation, pawl body 41b comes pressure contact with the internal surface of sliding contact part 38c (37c, 39c, or 40c). Consequently, internal surfaces of engaged grooves 37b-40b are never worn because of resistance to wear of sliding contact parts 37c-40c, so that functions of the fork can be held invariably normal.
