Title: Space forming device of slide fastener chain made of synthetic resin
Inventor: BANDOU HIDEO
IPC: B29C37/00
Filed: 1978-10-16
Abstract: PURPOSE: To provide the subject device wherein the removing block has a specific constitution and is caused to cooperate with the thrusting block to clamp-press the mesh-teeth, and the mesh-teeth are peeled off by a scraper thereby to smoothen the opening of the mesh-teeth foot part and to remove the possibility of the worms being cut off.  
     CONSTITUTION: The fastener chain is guided in a state where mesh-teeth are enmeshed with each other and brought to a stop between stationary and movable  clamps 9 and 10. The tape 2 is clamped and the front and rear parts of the mesh- teeth 3 are clamp-pressed between the removing block 6 and thrusting block 7.  Upon this occasion, the upper and lower surfaces of the teeth foot part 5 are respectively opened by the lever action of the claw 8 of the block 7 and the tape cord 1  and the functions of both corner parts 6 and 6' of the block 6 scraped off at an angle of 25W45 degrees. The blocks 6 and 7 are caused to descend in this state, and  the teeth 3 are separated from the tape cord 1 as they are clamped. Thereafter,  both blocks 6 and 7 are restored to original positions and teeth 3 adhering on the  block 7 are scraped off by a scraper 20.

IPC: H02K1/28
Filed: 1990-05-16
Abstract: PURPOSE:To facilitate a manufacturing process by forming notch sections among bridge sections formed to a core plate and laminating the core plates while successively displacing the notches. CONSTITUTION:Bridge sections 20 project along the circumferential direction of a core plate 12 from both sides of the front end of the outer circumferential section of a tooth section 14. The bridge sections 20 are composed of bridge sections 20a and 20b, the bridge sections 20a project from tooth sections 14a formed at every 90 deg., and the bridge sections 20b are project from tooth sections 14b displaced from the tooth sections 14a at an angle of 45 deg.. Consequently, the bridge sections 20a and 20b are arranged alternately in the circumferential direction of the core plate 12. Notch sections 22 at space C are formed among each bridge section 20a and 20b respectively. The size A of the bridge sections 20a is shaped larger than that B of the bridge sections 20b at that time. Accord ingly, since the core plates are laminated while successively displacing the notch sections formed among the bridge sections, the accuracy of finishing of the thickness of the bridge sections may not be precise, thus facilitating the manufacture of a core.

IPC: H04B10/2507
Filed: 1989-05-22
Abstract: PURPOSE:To remove a noise due to a natural emitted light generated in an optical amplifier without using an optical BPF by optical-amplifying an incident optical pulse, converting the wavelength of the incident optical pulse with a secondary non-linear optical effect and executing a photodetection. CONSTITUTION:The optical pulse passes a dichroic mirror 3 and is made incident on an optical fiber 2 to which an erbium (Er) element is added. It is amplified by the added part of the Er element excited by an exciting light source 1. Next, it is pulse-compressed with a Karr effect generated in the fiber 2 and the effect of a diffusion, guided to a crystal 6 for a second higher harmonics generation (SHG) through a lens 4 and wavelength-converted. Only the wavelength-converted optical pulse to pass a filter 7 is converged with a lens 5, reaches a photodetector 8 and is converted to an electric signal. Thus, the noise due to the natural emitted light generated in the optical amplifier can be removed.

Title: Chilling tendency evaluation method for molten metal and device therefor, and manufacture of cast iron using the evaluation method
Inventor: NAKANO EIJI
IPC: C21C1/10
Filed: 1994-06-10
Abstract: PURPOSE:To provide an evaluation method for the chilling tendency of molten metal, indispensable to the development and manufacture of such molten metal as hardly chilled, and useful for the quality control of molten metal as well CONSTITUTION:A critical cooling rate for chill crystallization is obtained via the analysis of the cooling curve where the cooling rate is variously changed, and a chilling tendency is evaluated on the basis of a difference in the critical cooling rate. In this case, the obtainable critical cooling rate is quantitative and universal with the unit expressed by  deg.C/S. Thus, the chilling tendency can be examined via an objective comparison. Also, a measurement section and a tissue observation section can be made to agree to each other on the cooling curve. Accurate evaluation can, therefore, be made with cooling state properly related to chill crystallization. Furthermore, cast iron free from chill can be efficiently produced, using molten metal adjusted to optimum properties, according a cast iron manufacturing method using the chilling tendency evaluation method for the molten metal.

Title: Code reader
Inventor: NAKAZAWA ATSUSHI
IPC: G06K7/10
Filed: 1990-05-17
Abstract: PURPOSE:To quickly and accurately read an object by limiting the quantity of reception light to a reference value at the time of extreme rise of the quantity. CONSTITUTION:A signal Va from a photodetector 7 is converted to a signal Vb by a light reception circuit 91 and is taken out by a peak hold circuit 92 as a waveform Vc which has the peak level held. In the first scanning, the peak level value is determined by a maximum light reception level corresponding to the reflection level from a white part and is scarcely reduced at least during scanning. That is, the circuit 92 has a time constant to hold the peak level in the first scanning. When the waveform Vc does not reach a reference value Vo, it passes a peak value limiting circuit 93 as it is; but when it exceeds the value Vo, it is limited to the value Vo. A gain control circuit 94 automatically controls the gain of an amplifying circuit 95 by the output of the circuit 93 having the value Vo as the upper limit. Consequently, the gain of the circuit 95 is not extremely reduced by the circuit 94 though the reflected light from the object surface is quickly increased, and thereby, a bar code is quickly and accurately read with respect to reflected light in the normal level.
