Title: Gear forming device
Inventor: NAKAMURA SUKEHIDE
IPC: B21H5/00
Filed: 1990-03-30
Abstract: PURPOSE:To form a gear tooth part high in cylindricity by forming the teeth half way in the beginning as thrusting force is weakened by a front both part having a twisted angle larger than an estimated twisted angle of a tooth trace to be formed, then, forming the teeth by the rear tooth part having an estimated twisted angle. CONSTITUTION:In the beginning, an annular stock 1 is formed by the front tooth part 20 of a form rolling die 7 larger than an estimated twisted angle. Since the thrusting force of the annular stock 1 to the radial direction is small and the tooth forming force is large, the teeth begins to be formed in the annular stock 1 as elliptical deformation and enlargement of an axial hole are restrained effectively. After the forming of the teeth is completed by the front tooth part 20a, the forming is performed by the rear tooth part 20b of the form rolling die 7 equivalent to the estimated twisted angle. The teeth of the annular stock 1 are formed as the thrusting force is increased by the front and rear tooth parts of the form rolling die 7 form a small value. Consequently, the forming of the teeth is completed in a short time and the cycle time for forming the teeth can be reduced.

Title: Optical glass element
Inventor: FUKUTE KAORI
IPC: C03C27/06
Filed: 1989-04-11
Abstract: PURPOSE:To prevent weathering of the element from occurring and to stably maintain the characteristic of optical glass for a long period by sticking a vitreous or light-transmissive crystal on both flat surfaces of a glass coated with a film consisting essentially of SiO2 on the whole side periphery and its vicinity. CONSTITUTION:The optical glass element is provided with a glass coated with a film contg. >=80wt.% SiO2 and 0-20wt.% of at least one kind among Al2O3, TiO2, ZrO2 and CeO2 and having 20-200nm thickness at least on the whole side periphery and its vicinity and a vitreous or light-transmissive crystal having excellent chemical resistance stuck on both flat surfaces of the glass. Although weathering can be prevented by the coating film contg. only SiO2, the weatherability is further enhanced by adding one of Al2O3, TiO2, ZrO2 and CeO2. However, since such materials have a relatively high refractive index, the transmissivity is lowered when the amt. of the materials to be added exceeds 20wt.%, and the optical glass characteristic is unfavorably deteriorated.

Abstract: PURPOSE:To obtain a normalizing circuit of floating-point operation which is operated in a high speed, by providing a mantissa bit data storage register, a preceding ''1'' detecting circuit, an encoder which encodes data to a binary code, and a shifter which shifts left bit data. CONSTITUTION:Bit data ''0000000001011011 of a mantissa 1b of an operation result to be normalized is inputted from a register 1 to a preceding ''1'' detecting circuit 2. The detecting circuit 2 detects that data D6 is ''1'' nearest to the most significant bit, and the circuit 2 activates only an output line S6 and leaves the other output lines unactivated. An encoder 3 receives data on the activated output line S6 and outputs 4-bit conversion code ''1001'' corresponding to the bit of data D6. By this output, a variable length bit shifter 4 is controlled to shift data left by 9 bits. Consequently, data stored in the register 1 is shifted left by 9 bits through the shifter 4 and is normalized. That is, data becomes ''1011011000000000''.
