Title: Sound absorbing material
Inventor: WAGATA SHIGEKI
IPC: E01F8/02
Filed: 1997-03-12
Abstract: PROBLEM TO BE SOLVED: To improve the sound absorbing effect by laminating a foam aluminum material layer and a polymer fiber material layer of a polyester fiber layer having specific thickness and density. SOLUTION: A polymer fiber material layer 4 is laminated on a foam aluminum material layer 2 to form a sound absorbing material M. When the layer 4 is formed with polyester fibers, the thickness is set to 20-100mm, and the density is set to 20-80kg/m<3> . When sound waves enter the sound absorbing material M, the vibrations of air particles are transferred to the air in fine holes, the vibrational energy of the air particles is changed into thermal energy and absorbed via the frictional resistance in the fine holes. The frictional resistance is applied stronger in a higher-sound zone having a larger vibrating speed, and the sound absorption coefficient of the porous material is increased in the higher-sound zone.  The layer 4 has a small sound absorbing effect in a low-frequency zone singularly, however the sound absorption coefficient in the low-frequency zone is remarkably increased when the layer 4 is laminated on the layer 2. This sound absorbing material M can effectively absorb sound, it can be made thin in thickness, the polyester fibers can be easily handled, and environmental pollution can be prevented.

Title: Hybrid ic optical receiver
Inventor: NISHIE MITSUAKI
IPC: H04B10/2507
Filed: 1985-03-20
Abstract: PURPOSE:To reduce the floating capacity equivalently and to reduce the influence upon a band by dividing and earthing the floating capacity which is parasitic between both ends of a feedback resistance belonging to an amplifier. CONSTITUTION:A case 10 of a hybrid IC optical receiver is closed with a metallic cover 30 whose outline is indicated by a dotted line, and the cover 30 is earthed. Thus, a capacitor is formed between a feedback resistance 26, namely, RL of an amplifier 18 and the cover 30, and this capacitor is distributed through the feedback resistance RL and has one pole earthed. Consequently, when this state is indicated equivalently, a parasitic capacity CL is not inputted in parallel to the feedback resistance RL, and the capacity is divided to an input side CL1 and an output side CL2. As the result, the floating capacity CL is made very small, and the influence upon the band is reduced considerably.

Filed: 1978-05-17
Abstract: PURPOSE: To make it possible to divide a semiconductor into pellets efficiently and also to reduce defects such as cracking of a semiconductor by sequentially carrying out the scribing and cracking of a wafer on the same table.  
     CONSTITUTION: Semiconductor wafer 1 with formed elements is placed on table 2 and then fixed hard by vacuum-suction. In this case, the wafer is so mounted that boundary lines of each element will agree with lines kof longitudinal and lateral V grooves 9 of the table. Next, scribing grooves 5 are formed along boundary lines of respective elements. That results in the agreement between scribing grooves 5 and V grooves 9. Next, high-pressure air is jetted out from air jet aperture 10 momently with the wafer fixed onto the table. In this case, impulsive force  P 1  of the high-pressure air is applied upward to the corresponding part of the scribing groove and vacuum adsorption force P 2  is also applied downward to the wafer  at the intermediate part. In consequence, the wafer is divided, under the influence  of scribing, at weak parts with a strain layer and then separated momently into  pellets bounded at scribing grooves.

Abstract: PURPOSE:To maintain the frequency of a power system at a reference value by providing a circuit for forming the reference value of effective power, a circuit for regulating the current value of a superconducting coil between allowable values, and a circuit for pulling back the current value of the superconducting coil within the allowable range. CONSTITUTION:When a signal (f) is inputted to a highpass filter 18-1, only quickly varying components are extracted at the output thereof. Output from the highpass filter 18-1 is fed to a transmission function 18-2 which produces an effective power reference value Pref. When the current id of a superconducting coil is inputted to a lowpass filter 26-1, an average component idm is detected. A comparator 26-2 compares a command value idms with the average component idm and an error signal epsiloni is inputted to a control function. Gate of a converter is controlled according to the output from the control function, i.e., a control value Pr2-1. On the other hand, an output i0 is obtained only when the current id deviates from the allowable range. The output i0 is inputted to the control function thus obtaining a control value Pr2-2.

Title: Connecting method for graphite electrode and metallic conducting bar
Inventor: SATOU TAKATOSHI
IPC: C25B11/14
Filed: 1981-04-21
Abstract: PURPOSE: To prevent the failure of a graphite electrode body at the time of connection and to achieve firm bonding and superior flow of current by forming screws to the graphite electrode body and a metallic conducting bar in such a way that buffer zones are formed, and coating a conductive material on the screw parts then locking these together.  
     CONSTITUTION: The diameter of the external screw to be formed to a metallic conducting bar 2 is made slightly smaller than the diameter of the internal screw formed to a graphite electrode body 1, more than in an ordinary case of screw coupling, so that a gap is produced when these are screwed together. A paste- like conductive material 3 is coated in this space, and while it is held packed in the spacing of the coupling part, the screws are locked together. By this connecting method, the fastening operation is accomplished smoothly by the fluidity of the conductive material existing in the clearance between the screw parts. The damaging of the connected part owing to the change in the external pressure and temp. during the use after connection is obviated.
