Title: Non-destructive inspection method of injection mold insulating material
Inventor: NAKANO TOSHIYUKI
IPC: G01J3/46
Filed: 1995-08-08
Abstract: PROBLEM TO BE SOLVED: To perform thermal history estimation of injection mold insulating material by estimating average temperature of the injection mold insulating material at the time of secondary hardening from a color difference between reference color found to color-measure the surface of the injection mold insulating material taken out from a mold in an L*a*b* color indicating system after primary hardening and color of the surface of the injection mold insulating material at the time of secondary hardening. SOLUTION: The surface of an insulating spacer taken out from a mold after primary hardening is color-measured in an *a*b* color indicating system, it is made reference color, and a color difference between the reference color and color of the surface of the insulating spacer after secondary hardening is found. In this case, the color difference is independent of a resin system in the case up to about 15, and in regard to hardening temperature the more a hardening time, the more the color difference linearly.  Accordingly, the relation between hardening temperature of and the hardening time of equi-color difference curve (ΔE*ab curve) is found by previously using a test piece, and in the known case of the secondary hardening time, thermal history at the time of the secondary hardening of the insulating spacer can be non- destructively found by graphing the relation and referring to the graph.

Title: Automatic dial-tone connecting system when called subscriber line is busy
Inventor: NAKAZAWA MASARU
IPC: H04M3/42
Filed: 1984-09-27
Abstract: PURPOSE:To automatically send dial tone to a called subscriber when his line is busy, by providing a calling subscriber class discriminating memory which discriminates the class of calling subscribers and makes recalling possible when a relevant calling subscriber meets line's busy on a called subscriber side and a counter memory for specifying a recalling number of times. CONSTITUTION:When a calling subscriber 1 dials to call up a called subscriber, the received figures are analyzed in an exchange and, when the received numerals are correct and the called side is vacant, the calling subscriber 1 is properly connected with the called side. However, when the received numerals are not correct or the called side is busy, the connection is not performed and busy tone BT is sent to the calling subscriber 1 from a busy tone generator 4. Then direct transition from the state where the busy tone is sent to another state where specifying tone is sent is not made, but whether or not the calling subscriber joins this service is read out and discriminated from a memory. When the calling subscriber joins this service, the busy tone sending state is transferred to a dial tone sending state, and thus, a recallable condition is set. In addition, a counter memory for counting the recalling number of times is provided and, when the recalling number of times exceeds a specified value, the recalling is stopped.

Title: Semiconductor laser device
Inventor: MIYAZAWA SEIICHI
IPC: H01S5/00
Filed: 1995-08-08
Abstract: PURPOSE:To obtain the title high reliable semiconductor laser device excellent in current constriction and photo-confinement by a method wherein the p conductivity type is adopted for the part positioned on a slope of a protrusion with trapezoidal section while n conductivity type is adopted for the part positioned on the top surface part of the protrusion with trapezoidal section. CONSTITUTION:Within a trench formed on a substrate 51, a bottom surface has a flat part (001) surface while both depth and width of the bottom part are 1.0mum and the angle theta of the trench slope making with the bottom surface is about 55 deg.. When Si doped GaAs is grown on this trench, the part 60 only formed on the slope will become p type while the part formed on the (001) surface will become n type. At this time, the reason why the bottom surface of the trench part is flattened is the fact that if the bottom part is made rugged with the trench taking V shape, the crystal grown thereon may be notably dispersed. On the contrary, if the bottom surface of the trench part is flattened, the crystallizability of the part corres-ponding to bottom part will be made excellent, thereby enabling the beam of an excellent efficiency to be emitted. Furthermore, due to the curvature of an active layer 54, excellent photo- confinement effect can be gained.

IPC: C08K5/5455
Filed: 1988-08-15
Abstract: PURPOSE:To obtain a polymer material compsn. having a long-term light resistance by incorporating a specified benzotriazole compd. into a polymer material. CONSTITUTION:0.001-5 pts. benzotriazole compd. of formula I [wherein R is a group of formula II (wherein X is H or a halogen; R2 is H or 1-12C alkyl; R3 is a 2-4C alkylene)] (e.g., a compd. of formula III) as a light stabilizer is added to 100 pts.wt. polymer material (e.g., PP). A polymer material compsn. having a long-term light resistance is obtd. by using said light stabilizer. Up to this time, it has been believed that a UV absorber of 2- hydroxyphenylbenzotriazole had a large stabilizing effect, but is exhibited itself poor heat resistance and was unsatisfactory for practical use. In addition, dimmer compd. thereof was also proposed, but the compd. itself exhibited defect in its heat resistance. When the compd. of formula I is used, the polymer compsn. exhibits improved light resistance for a much longer period than said conventional compd. does.

Abstract: PURPOSE:To avoid the production of a discontinuous point of an FSK signal at a change point of a PCM data by storing a sinusoidal wave signal to a ROM 9 and changing a speed reading the storage data of the ROM depending on the PCM data. CONSTITUTION:When the PCM data is logical '0', a selector 3 gives an output signal of the 1st frequency divider 6 frequency-dividing the frequency (f) of an oscillator 5 by f/K to a counter 8, and the data of the sinusoidal wave signal being the result of division of one period stored in a ROM 9 at a speed of f/K by 2M equally is read in order. Moreover, when the PCM data is logical 1, an output signal of the 2nd frequency divider 7 frequency-dividing the frequency (f) of the oscillator 5 by f/L is fed to the counter 8 and the data of the ROM 9 is read in order at a speed of f/L. When the PCM data is changed in this way, the operating speed of the counter 8 is changed and the data read from the ROM 9 is changed continuously, then no discontinuous point is generated at the analog signal output of a D/A conversion circuit 10. Thus, no discontinuous point of the FSK signal is caused at the change point of the PCM data.
