IPC: H05K1/02
Filed: 1995-02-22
Abstract: PURPOSE: To make a cutting process unnecessary and simply splitting alone enough by providing splitting sections, to be formed at two sites forking the tips of end sections into two branches respectively in the longitudinal direction of splitting slits, more inside than the product ends. CONSTITUTION: Slits 12 are formed in a printed board 11, and the tips of the slits are formed into u-shape. When this is split, it is split along splitting section 13 where splitting strength is weak. Namely, it is split into a product section 14 and a member 15. In addition, the member 15 is split into the remaining section 16 and a product section 14, when it is split. At this time, burrs 17 are produced more inside than the product end surface 14a of the product section 14, and the burrs do not touch other members, since the slit tips are u-shaped, even when the product end surface 14a is joined by insertion to another member. And it becomes possible to make the burrs 17 smaller in the end, if parts of the u-shaped slit tips are formed into an arc shape, to make it more favorable, since stresses are hardly applied to those parts concentrically.

Title: Photometer
Inventor: SANPEI YOSHIHIRO
IPC: G01B11/00
Filed: 1995-03-20
Abstract: PURPOSE: To make possible collecting, eliminating or lowering of polarization characteristic by providing computing/correcting section to correct changes in output attributed to dependence on polarization based on outputs of a photo- detector and a photodetecting part. CONSTITUTION: At least one polarization of linearly polarized components of incident light is extracted by a monitoring part 1 to detect the power by a photo-detector 2. After the light from the monitoring part 1 is received, the light emitted from a main optical system 3 is detected by a photodetecting section 4. In other words, the photodetecting section 4 detects the sum of the power of the linearly polarized component outputted from the main optical system 3. A computing/correcting section 5 corrects changes in outputted attributed to the dependence on polarization based on outputs of the photodetector 2 and the photodetecting section 4.  This makes possible the obtaining of an output (output corresponding to the power of the incident light) with changes in output canceled otherwise following the changes in polarization thereby eliminating the dependence on the polarization easily with respect to arbitrary polarization state.

Abstract: PURPOSE:To compensate aberrations excellently by composing a zoom lens of a front group with a positive refractive index and a rear group with a negative refractive index, including a biconcave lens in the rear group, and specifying the radius of curvature of the biconcave lens. CONSTITUTION:The front group I with the positive refractive index is constituted containing a positive meniscus lens having its convex surface opposite a body, a negative lens, and >=1 positive lens from an object side. Further, the rear group II with the negative refractive index is constituted containing a positive lens, the biconcave lens (a), and a negative meniscus lens having its convex surface on the image side from the object side. Then the radius of curvature of the biconcave lens (a) of the rear group II is set satisfying an inequality. Here, ra and rb indicate the radii of curvature on the body side and image side. Then the gap between the front group I and rear group II of the zoom lens is varied to vary the power. Thus, the radius of curvature of the biconcave lens is specified, so the zoom lens is made compact by shortening the overall length and reducing the movement quantity at the time of the power variation although the power variation ratio is large as 2.

IPC: H03F1/32
Filed: 1981-04-20
Abstract: PURPOSE: To increase the reliability and to reduce the cost, by making the compensation of differentiating gain and differentiating phase within one amplifying circuit and reducing the number of components and adjusting positions.  
     CONSTITUTION: The gain G of an amplifying circuit is expressed as -G=Z c /Z e , where the Z c  is a collector resistor 4 and the Z e  is the synthesis of a resistor 5 and an impedance of a compensating circuit 50i connected in parallel with the resistor 5. A voltage of a given power supply V' is set corresponding to the change in distortion. When an input signal is a small value, since the emitter voltage is low, all diodes D 50i  are turned on and the impedance of the emitter is the sum of all parallel resistors R ei , 5 and capacitors C i . As the voltage of an input signal is increased, first a diode D 501  turns off and the compensation circuit 50 is disconnected. Further, when the input signal voltage increases, the diodes turn off in the order of D 2 , D 3 ∼, and the real part of the impedance Z e  is greater and the gain is reduced.

Title: Surface acoustic wave filter
Inventor: HAZAMA TAKESHI
IPC: H03H3/08
Filed: 1986-03-20
Abstract: PURPOSE:To provide a characteristic compensating a group delay characteristic of an external circuit by shifting a main lobe from the center of a converter to a remote side to a normal IDT. CONSTITUTION:The pitch of a side lobe formed by the 10th-30th IDTs is slightly larger than the pitch of a main lobe formed by the 40th-80th IDTs. Since the position of input/output IDTs is decided so that the side lobe approaches from the main lobe to the output IDT, a signal near a chrominance carrier is advanced timewise than the signal near the center frequency of a filter. The frequency characteristic of the group delay time is an excellent flat characteristic of about 750+ or -50ns at the frequency band between a video carrier frequency fp and a chrominance signal carrier frequency fc+500kHz,and advanced sequentially as nearly 650ns at the fc and nearly 300ns at (fc-500kHz) in the frequency below fc+500Hz and the difference between values at the flat region and (fc-500kHz) is nearly 450ns.
