Title: Multi-process thread rolling method for screw and its dies
Inventor: MURAKAMI SUZUYA
IPC: B21H3/04
Filed: 1978-03-06
Abstract: PURPOSE: To make possible the efficient titled thread rolling for a screw without necessity of long hours like as the conventional method, at the thread rolling of a complexed shape, by treating with the free thread rolling roller dies consisting of multi-process.  
     CONSTITUTION: The required number of teeth are indexed on the outer surface of the blank by the first process dies, and the lead groove is formed; after that, the required product profile is generated by the second process dies. When the number of teeth of the product is taken as (n), similarly its pitch circle radius as rp, the  number of teeth of the second process roller dies as N, and its pitch circle radius as  kp, the number of teeth N is determined by the formula (RP/N 2 ≈rp/n), in which  RP is selected from the specified range. Next, the profile of each of the second  process roller dies and the first process roller dies (including the determination of  number of teeth), is successively determined depending on the separate formula and  procedure. In the second process, required times of process are repeated by plural  sets of roller dies, and the profile of the product is formed. According to this method, the titled screw can be more simply and efficiently thread rolled as compared  with the conventional method of cutting work.

IPC: G11B19/04
Filed: 1998-02-05
Abstract: PROBLEM TO BE SOLVED: To realize a high-density recording by setting a flutter amplitude to be equal to or less than a value in which a flutter component in the positioning error of a magnetic head which is to be set as the specific ratio of the track pitch of a magnetic disk is divided by the multiplication value of a prescribed conversion rate and a sensitivity function to suppress the vibration of the magnetic disk within a tolerance range even in a high-speed revolution. SOLUTION: About 1/20 of the track pitch P of a magnetic disk is made to be the allowed value H of the flutter component in the positioning error of a magnetic head. An allowable flutter component H is calculated and, next, the restriction value of a flutter amplitude Z is calculated by comparing flutter amplitudes measured by changing revolving speeds and disk thicknesses in an actual divice. Then, the high- density recording of the magnetic disk is realized by suppressing the width of the vibration of the magnetic disk within the tolerance range while setting the flutter amplitude Z to be equal to or less than a value in which the flutter component H is divided by the multiplication value of a conversion rate S and a sensitivity function K and while deciding the revolving speed in accordance with the necessary number of tracks per one inch and a disk thickness.

Abstract: PURPOSE:To prevent the stepwise disconnection and the disconnection of a wire in a semiconductor device by contacting the end of a bonded wire having a spherical part including a diameter larger than the infinitesimal interval between isolated or adjacent metallic wire layers between the wire layers formed on the surface of the semiconductor element. CONSTITUTION:When the first SiO2 layer 2 is formed on the entire surface of a semiconductor substrate 1, a PSG layer 3 and the second SiO2 layer 2' are partly laminated thereon and an aluminum wire layer 4 is formed by evaporation over the stepwise part therebetween, the wire is disconnected at the stepwise part to isolate therebetween at an infinitesimal interval. When the interval is, for example, 10mum, the end of a bonding wire having a spherical part including a diameter of 100mum is thermally bonded solderlessly thereto. When a window for mounting an electrode of an SiO2 layer 14 formed without a stepwise part is wire bonded, it is similarly bonded. This can prevent the stepwise disconnection and the disconnection of the wire in the semiconductor device.

Filed: 1983-02-17
Abstract: PURPOSE:To improve the utilizing efficiency of a central processing unit by continuing the succeeding processing by a communication control mechanism when the communication control mechanism receives an affirmative response from a terminal device. CONSTITUTION:When a CPU1 gives a write instruction and transmits an SEL signal urging reception to transmit data to a terminal device 4, the device 4 returns a response signal to a line control mechanism 6. The mechanism 6 receives this signal ACK0 at a detecting section 7 and when the response signal is an affirmative signal, the mechanism 6 operates a channel 5 and applies write processing (data transmission) to the device 4. The device 4 transmits a signal ACK1 to the mechanism 6 when the data reception is finished. The mechanism 6 detects the ACK1 and transmits the signal of normal end to the channel 5 when it is the affirmative signal. The channel 5 transmits an interruption signal to the CPU1. Thus, one interruption is attained against one response.
