Title: Cushioning material and its manufacture
Inventor: SHIMIZU KAORU
IPC: B65D81/113
Filed: 1996-11-01
Abstract: PROBLEM TO BE SOLVED: To obtain a cushioning material having excellent shock-absorbing characteristics by primarily heating a mixed member comprising waste paper, electrically conductive fibers and a void forming member to swell the void forming member and, thereafter, secondarily heating a resultant form to shrink the void forming member and to form voids in the form comprising crushed waste paper. SOLUTION: Materials prepared by adding water to waste paper 1 and a waste polystyrene foam 3, respectively, and crushing them by mixers 2 are mixed together with electrically conductive fibers 14 and a surfactant 4. The mixture is poured into a wood mold 5 and, when the mixture is heated with electromagnetic waves for about six minutes by using a microwave oven 8 while an upper lid 7 of the wood mold 5 is being kept open up to a necessary height, the waste polystyrene foam 3 is put into a swollen state under heating. Thereafter, a form thus obtained is taken out of the wood pattern 5 to be heated and dried in a small-sized drying oven 9 at 150-200 deg.C for about 15-30 minutes. Thus, when moisture is sufficiently removed, the waste polystyrene foam 3 is melted and shrinked, and voids are formed in pulp.  By this method, a cushioning material having excellent shock-absorbing properties is obtained and can be applied to the packing of a large-sized product.

Title: Working discrimination device of vibration tool
Inventor: YOSHIMURA KAZUYA
IPC: B25B23/145
Filed: 1998-10-14
Abstract: PROBLEM TO BE SOLVED: To precisely discriminate whether or not the working by a vibration tool is normally done. SOLUTION: A vibration sensor is mounted to a vibration tool of caulking impact, etc., a vibration wave form of the vibration tool is detected. For 2 sec starting after 0.1 sec from working start of the vibration tool, a number of the values lower than the lower limit value Vmin among bottom values of the detected vibration wave form is counted, when the counted number is four or more, the working is discriminated normal. Under an abnormal state where the vibration tool strikes as unloaded, the number of bottom values of a vibration wave form lower than Vmin is not turned out to be 4 or more. In this case, it is discriminated that the working is not done normally and an alarm is issued.

Title: Dry etching method
Inventor: KOSHIMIZU CHISHIO
IPC: H05H1/00
Filed: 1991-10-09
Abstract: PURPOSE:To exactly detect the end point of dry etching. CONSTITUTION:CHF3 gas and CF4 gas being reaction gas, and Ar gas for stabilizing plasma are introduced into a vacuum chamber 1. By applying electric power across electrodes 2 and 3, plasma is generated and an SiO2 film is etched. The light of luminescence wavelength of CF2 radicals participating in etching is picked up with a spectroscope 5, and its luminous intensity is monitored with a judging part 7. During etching, CF2 radicals are used for the reaction with SiO2. When the SiO2 film is eliminated, CF2 radicals do not participate in the above reaction, so that the luminous intensity of CF2 radicals increases. The increase of the luminous intensity is captured with the judging part 7, which judges the end point of etching.

IPC: G11B7/24088
Filed: 1986-12-10
Abstract: PURPOSE:To attain multi-recording and to obtain high recording density in a recording/reproducing system by forming a recording pit at a saturation level, and setting plural threshold values based on the peak level of the reproduced signal at the recording pit and the level of an unrecorded area. CONSTITUTION:The pits serving as prepits having such depth that provide a saturation level or the 1/4 depth laser wavelength of a using light source in general are previously formed in the header pits of each sector or in a data area with fixed spaces. In a reproducing mode, the peak level obtained from said prepit is regarded as the maximum amplitude value of a recording pit together with the reproduced signal level obtained from the unrecorded area is regarded as the minimum amplitude value, respectively. The value between both levels are divided into some steps of threshold value to previde the multi- value data. While in a recording mode a non-saturated area where the amplitude of the reproduced signal changes is used to the recording power for production of pits. Thus a multi-value recording operation is attained for information.
