Title: Manufacture of connecting rod
Inventor: HOSHINA EISUKE
IPC: B21K1/76
Filed: 1987-07-13
Abstract: PURPOSE:To manufacture a connecting rod capable of securing a stable engine performance by forming a cap part of a large end part of a forged rough profile material thinner in thickness than a rod part, making a cold coining of this part and then carrying out final mechanical finish. CONSTITUTION:A small end part 3 having a hole 5 on one end of a main body part 2 and a large end part 4 comprising a rod part 7 having a hole 6 and a cap 8 on the other end are provided by forging to obtain a rough profile material 1. Then, the cap part 8 is formed thinner than the rod part 7 on the large end part 4 of said rough profile material 1. After that, the rough profile material 1 undergoes cold coining. In that case, the cap part 8 is not compressed by coining, therefore, the residual stress hardly occurs. Then, the rod part 7 and cap part 8 are cut off within an allowance, and finish by mechanical working. Accordingly, the cap 8 free from deformation due to residual stress is combined exactly with the rod part 7, a connecting rod is made up in good dimensional stability and stable engine performance is secured.

Title: Rotating power transmission mechanism
Inventor: INAGAKI HIDEHIKO
IPC: F16H35/00
Filed: 1985-08-08
Abstract: PURPOSE:To coincide the rotating direction of an input shaft with that of an output shaft, and to prevent reversing of the output shaft by uniting a friction plate, a ratchet wheel and a transmission gear in a body with one side or the other side of the output shaft by input rotation of the input shaft. CONSTITUTION:When an input shaft 14 is rotated in direction of an arrow A, the rotation of the input shaft 14 is transmitted to a spur gear 12 through a spur gear 13. The spur gear 12 is moved to a ratchet wheel permitted to rotate in the same direction, and the spur gear 12, the ratchet wheel 5 and the friction plate 3 are united in a body to be rotated. Thus, an output shaft 1 is rotated in the same direction as the spur gear 12. Even if the reversing force works upon the input shaft 1 at this time, the rotation of the ratchet wheel 5 is regulated by a click 7 to keep the output shaft 1 from reversing.

IPC: H01S5/00
Filed: 1998-06-23
Abstract: PROBLEM TO BE SOLVED: To improve the temperature characteristic of a semiconductor laser by utilizing quantization effect by preventing the laser from being affected by a phonon bottle neck phenomenon by restricting the quantum level formed in a quantum dot to one. SOLUTION: At least one of the discrete energy level on the conduction band side or valence band side of a quantum dot 1 is restricted to one. When at least one of the discrete energy level, namely the quantum levels on the conduction band side or valence band side of the quantum dot 1 is restricted to one, namely to a base level 7, in such a way the carrier injected into an active layer 4 or its vicinity is relaxed to the base level 7 in a short relaxation time of bout 1-10 ps in the Auger process. Consequently, the carrier required for laser oscillation can be replenished in a short time, without receiving the influence of a phonon bottle neck phenomenon. Therefore, the operating characteristics of a semiconductor laser can be improved.

When said procedure is repeated, the minimum value is finally left in either one of a P register 2 and a Q register 1. On the other hand, the address of data newly set up as a minimum value in each updating the preceding minimum value is stored in an AD register. Consequently, the minimum value of (n) data and its address can be found out by n cycles, reducing the operation time of the circuit.

Title: Noise pulse eliminating circuit
Inventor: SUZUKA KAZUO
IPC: H03K5/1252
Filed: 1980-12-15
Abstract: PURPOSE:To eliminate surely single or repeatedly inputted noise pulses, by connecting two coutners successively and by making the operation time of the counter of the succeeding stage longer than that of the counter of the preceding stage. CONSTITUTION:Counters 21 and 22 are quad and octal counters respectively. When a noise pulse of the positive polarity which has the duration shorter than the period of a clock signal is inputted to a terminal (a), the counter 21 is changed to the active state, but the counter 21 is reset before completion of the counting operation not to change the state of an output terminal 212. When a noise pulse of the negative polarity is inputted, the counter 21 is reset, but the counter 22 becomes the active state. When the noise pulse is terminated, the counter 21 becomes the active state to start counting the clock signal, but the counter 21 is reset before the counter 22 completes counting, and therefore, the state of an output terminal (c) is not changed. Even if noise pulses are inputted repeatedly, the counter 22 is not influenced.
