Title: Structure of core metal for elastic caterpillar band
Inventor: FURUTA MITSUO
IPC: B62D55/253
Filed: 1990-03-28
Abstract: PURPOSE:To improve the durability and strength by forming a pair of projection parts at a core metal basic part embedded into a caterpillar band and forming each thick part outside each projection part and allowing supporting wheels for a caterpillar band to travel on the top surface of each thick part. CONSTITUTION:A core metal 1 is used in the embedded state into a caterpillar band laid onto driving wheels, free wheels, and supporting wheels in a traveling device. In this case, as for the core metal 1, a core metal basic part 2 is embedded into the caterpillar band, and a pair of projection parts 3 are installed onto the core metal basic part 2. Further, outside each projection part 3, a pair of thick parts 4 are arranged towards the inside of the caterpillar band from the core metal basic part 2. A supporting wheel is traveled on the top surface 5 of each thick part 4. In other words, the core metal basic part 2 as rigid body and the supporting wheel which is similarly rigid body are brought into direct contact, and no elastic body is interposed between the both. Therefore, the sufficient strength and durability can be secured.

Title: Noise reduction system at non-talking
Inventor: AOKI YASUSHI
IPC: H04B14/04
Filed: 1984-04-20
Abstract: PURPOSE:To reduce the increase in noise at non-talking because of a harmonic distortion component of a sinusoidal wave pilot signal for supervising fault by inserting the 2nd sinusoidal wave signal to an idle band in addition to a sinusoidal wave pilot signal. CONSTITUTION:An FDM signal is converted into a PCM signal by an A/D converter 3 and then transmitted to a transmission line. The PCM signal is converted into a PAM signal by a D/A converter 4 at the reception side, and an unnecessary band component is eliminated by a band stop filter 5 and the FDM signal is reproduced. A sinusoidal wave pilot signal for detecting a fault in a frequency fp is generated by a pilot signal generating source 6 and added to the FDM signal by an adder 2 provided before the A/D converter 3 together with a sinusoidal wave in frequency fp' generated by a sinusoidal wave generating source 7 generating the 2nd sinusoidal wave signal. The signal branched after a D/A converter 4 passes through a low pass filter 8 having the cutoff frequency fp at the reception side. The signal passing through the filter 8 is only the sinusoidal wave pilot signal for detecting a fault and the output of the filter 8 is supervised for the level or phase by a pilot signal detecting circuit 9.

Title: Kerosene burner
Inventor: KAWASAKI YOSHITAKA
IPC: F23D3/10
Filed: 1985-04-17
Abstract: PURPOSE:To contrive to keep uniform complete combustion by preventing the thermal deformation from occurring during the combustion of a burner by forming a structure wherein a cantilever holder is equipped in a flat combustion chamber and at the same time cantilever partition plates with openings are provided in the front and rear spaces formed between the flats of said combustion chamber and an outer tube. CONSTITUTION:Because a front and a back partition plates 21 and 22 do not press a portion of the wall surface of a combustion chamber so as to cause wavy deformation of the wall surface and keep the uniform planes and consequently prevent the wall surface from bending, a bad influence over the burning state and distribution of red heat is evaded and uniform complete combustion can be ensured over the whole region of the combustion chamber 17. Further, as for the danger of the generation of deforming stress towards the inside of the combustion chamber 17 by pressing with the front and back partition plates 21 and 22, a holder 20 provided in the combustion chamber 17 acts so as to keep the proper gap. At the same time, because the plates 21 and 22 and the holder 20 lie nearly at the same position (at the same height) in a horizontal cross section in parallel, their respective pressing forces balance with one another and consequently the normal shape of the combustion chamber can be kept.

Title: Semiconductor optical element
Inventor: SHIBATA NAOKI
IPC: H01L33/14
Filed: 1995-03-13
Abstract: PURPOSE: To provide a semiconductor optical element having a wire bonding electrode, which utilizes efficiently a current, which is made to flow, so as not to reduce the quality of the element. CONSTITUTION: A high-resistance layer (or an insulating layer) 14, which makes a current hard to flow, is formed thin on a semiconductor region under an electrode pad 10 having no relation directly with a light signal for light extraction, photodetection or the like. By the existence of this layer 14, the current is made hard to flow directly under the region of the pad 10 and is made to flow to a semiconductor layer located at the region other than the region of the pad 10. Accordingly, the current to contribute to the light emission of a semiconductor optical element is hardly eliminated directly under the region of the pad 10 and is made to flow only to the region to contribute to the light signal. Accordingly, when currents are one of the same current value, the currents are made to flow more to the region to contribute to the light signal.  As a result, the efficiency of a wire bonding electrode is improved. Moreover, as the current does not flow so much to the region under the pad 10, it is inhibited that the deterioration of the optical element is increased, the life, which is required as a product, of the element is prolonged and the quality of the optical element is improved.
