Abstract: PURPOSE:To form a row of teeth making the metal of flat part cut into rugged part of a forming die and to mass-produce light rack bars at high yield by forming a segmental cylindrical pipe having flat one side by press working a side of a pipe, fitting it into a forming die and pressing a punch into the pipe. CONSTITUTION:Lower opposing faces 11a, 12a of a pair of semi-cylindrical sectional dies 11, 12 for primary forming are in close contact without gap, and upper opposing faces 11b, 12b recede to the side and concave circular arcuate faces 11c, 12c are formed between sectional dies 11, 12. A material pipe 21 of nearly the same diameter with the rack bar is fitted tightly in the concave circular arcuate faces 11c, 12c. When a square rod-shaped press die 14 is pressed into a parallel groove 13, a segmental cylindrical primary formed body 22 having a flat part 22b is formed. Sectional dies 31, 32 for secondary forming are semi- cylindrical, and rugged faces 31a, 32a corresponding to the row of teeth of the rack bar are formed on the upper face of a recessed hole. A punch 33 is segmental cylinder having diameter nearly equal to inner diameter of the primary formed body 22. The primary formed body 22 is fitted in sectional dies 31, 32 for forming, and the punch 33 is pressed in forcibly to form a rack bar.

Title: Phase locked loop circuit and signal transmitter-receiver
Inventor: TANIGUCHI SHOJI
IPC: H04L7/033
Filed: 1991-04-09
Abstract: PURPOSE:To reduce the synchronization lock time at reception, to minimize sensitive phase correction at transmission and to improve the reliability by switching a synchronization protection stage number automatically without fixing the synchronization protection stage number to correct the title circuit. CONSTITUTION:A phase lead detection signal Sphi1 or a phase lag detection signal Sphi2 are inputted to a synchronization protection/control means 12. A synchronization protection control signal Ci representing number of synchronization protection stages is selected based on a phase of a signal RXD and a phase of a synchronization extraction clock Ci at the reception of the signal. An internal control signal CR based thereon is outputted to a frequency divider means 13. Moreover, when the signal RXD from a reception communication line L1 is processed by a reception means 14 at the transmission of a signal, the signal phi2 from a phase locked loop means 15 is subject to extraction processing by a control means 17. Thus, a transmission signal OXD based on the signal phi2 is outputted to a transmission communication line L2 from the transmission means 16 via the control means 17.

Abstract: PURPOSE:To make a ciphering key into disclosed identification information by transmitting and receiving the information to combine the secret information inherent to a user with a random number and the information to combine a message to be sent with a random number or the like and executing the ciphering decoding operation. CONSTITUTION:A user A inputs a value IDA of self-identification information (x) to an input terminal 1 and inputs a value IDB of the identification information of an opponent to an input terminal 2. A user B reads with a message reading circuit 5 and knows that a transmitting person is the user A. The user A inputs a message M to be communicated from the input terminal 11 to the user B by using the value IDB of the identification information of the user B. A random number rA is prepared by a random number generator 12, calculated by an arithmetic circuit C15 and this is sent through a communication path 4 to the user B. The user B operates with an arithmetic circuit 16 and obtains the message M from the user A from an output terminal 17 by using the value IDA of the identification information of the user A. Then, since the information of the secret communication is executed by the disclosed identification information of the user, the list of the ciphering key is not necessary.

An output signal from the compensating part 23 is then inputted to a second deviation detecting part 24 and a deviation from the output of a difference speed feed back part 26 is determined. In the difference speed feedback part 26, a deviation between a car speed outputted from a hydraulic system 25 and a motor speed is determined by means of a third deviation detecting part 26a and the deviation is outputted through a gain part 26b. A deviation output obtained by the second deviation detecting part 24 is fed to a hydraulic system, and the car speed of the hydraulic elevator and a motor speed are controlled.

IPC: H01L23/36
Filed: 1981-05-23
Abstract: PURPOSE:To obtain an aluminum heat sink having small size and high performance by casting part of plate-shaped fins of prescribed thickness and shape in a base. CONSTITUTION:Aluminum fins 2a formed in advance in the prescribed thickness and shape are aligned at the prescribed interval in parallel with each other, the edges of the same side are cast, and an aluminum base 2b of the prescribed outer diameter is integrally formed. When it is cast under pressure, no cavity is formed in the base 2b. A vacuum casting may be adopted. According to this structure, a fin base can be integrally formed similarly to the heat sink by an extruding die material or a casting, and when casting conditions are determined, an elevated technique is not necessary, and the manufacture can be simply facilitated. The shape and the thickness of the base can be arbitrarily formed, thin fins can be formed in high density, thereby enabling small size and high performance. When a copper plate is cast to a semiconductor element mounting surface 2b or a terminal mounting part at the time of casting under pressure, a preferable heat sink can be obtained with inexpensive cost.
