Title: Method and device for carrying substrate
Inventor: KUMAGAI OSAHISA
IPC: H01L21/68
Filed: 1994-09-28
Abstract: PURPOSE: To increase the allowable value to the dispersion of height of a carrying rail between carrying units so as to reduce the failure of carrying by giving the floating force, which is stronger than the floating force given to a substrate being carried inside of a carrying unit, to the substrate moving between the carrying units. CONSTITUTION: In a figure (a), a substrate 1 positioned at a central part on a rectangular carrying rail 15 is floated for progress by the compressed air 2 jetted from a compressed air jetting hole 3a. On the other hand, in a figure (b), the substrate 1 to be moved to a rectangular carrying rail 15-1a receives the floating force of an air bearing mechanism 3 of each rail part 15a, which is newly added to the rectangular rail 15, 15-1a showed with the oblique line in comparison with the conventional one. The substrate 1 in the condition showed with the figure (b) is floated higher than the substrate 1 in the condition showed with the figure (a). Height of the substrate 1 is related with the number of compressed air jetting hole 31 for helping float of the substrate 1.  As a result, the allowable value to the dispersion of height of the rail 15 can be increased, and the carrying failure can be reduced.

Title: Excavation method by blasting
Inventor: ARITA TAKEISA
IPC: F42D1/24
Filed: 1997-08-29
Abstract: PROBLEM TO BE SOLVED: To prevent a blasting powder from scattering out of a blasting hole by inserting a container made of a gas-permeable film in the blasting hole in a state of covering a charging hose and fixing the charging hose and an opening part of the container to each other and then blowing the blasting powder into the container by pressured air of a charging machine when a water-soluble blasting powder is charged in the blasting hole. SOLUTION: At the time of blasting, a container having an air permeability of 100-10,000 L/m<2> /S is inserted in a blasting hole in a state of covering a charging hole such as fuel explosive loader or the like. Then, if a water-soluble blasting powder (blasting powder) in bulk is charged in a container by pressed air, excessive air is discharged out of the container and the blasting powder remains in the container. The container is brought into close contact with an inner wall of the blasting hole by the charged blasting powder so that the container is interposed between the charged blasting powder and the inner wall of the blasting hole so as to block contact of the blasting powder with water and capacity of the blasting powder is maintained without being deteriorated.  Further, if a container having a water-soluble polymer attached to the container in advance is used, water in the blasting hole and the polymer undergo hydration reaction so as to be gelatinized so that penetration of water into the container is highly blocked.

Title: Waveform shaping circuit
Inventor: OONO YOSHITAKA
IPC: H03K17/795
Filed: 1983-12-14
Abstract: PURPOSE:To eliminate the need to adjust finely the operation point of a comparator part, and obtain excellent responsibility and use a unipolar control power source by setting resistance values of serial fixed resistances at both terminals among three resistances much larger than that of the center resistance in a waveform shaping circuit for a fine signal. CONSTITUTION:The resistance values of fixed resistances 8 and 9 are set much larger than that of the fixed resistance 3. When the input current I1 of a photocoupler 1 is 0, the output current I2 is also 0 and a voltage e1 is applied to the input terminal side of a comparator 2 on condition E1>E2 since a current flows through a positive power source 5, fixed resistances 8, 3, and 9, and ground 7. Then, the current I1 (=0) flows and a current I2 (=0) flows through a positive power source 5, TrT, resistance R, Zener diode 10, and ground 7. In this case, a current shunt to the resistance 9 is small enough to ignore. At this time, a voltage e2 is applied to the input terminal side of the comparator 2 on condition E1<E2 and an output voltage E3 is positive. Said condition E1<E2 is obtained by setting the values of the resistances 8, 3, and 9 properly.

Title: Rotary head magnetic picture recording/reproducing device
Inventor: KAWABATA MASARU
IPC: G11B15/087
Filed: 1984-11-05
Abstract: PURPOSE:To attain accurately a composite photography by recording a position signal on a magnetic tape by all width erasing head when the magnetic tape is rewound to reverse direction, and after a temporary stop is released, by reproducing a position signal on the magnetic tape and restart the recording of picture signal from that position. CONSTITUTION:When the magnetic tape is rewinded to the reverse direction, the signal to be reproduced by a rotary head 24 is sent to a recording signal detection circuit 27 through a switch 21, and a pilot signal is picked up therefrom. As low frequency is used for this pilot signal, it is not much affected by azimuth loss. Therefore, adequate reproduction output is obtained even though locus of the rotary head drawn on the magnetic tape does not coincide with the recorded pattern of the magnetic tape. By checking the pilot signal thus picked up, it is possible to obtain a signal by which the position of the recording pattern on the magnetic tape can be identified.

Title: Fixation temperature controller for copying machine
Inventor: KITAMURA TAKESHI
IPC: G03G15/20
Filed: 1986-10-01
Abstract: PURPOSE:To eliminate variance in copy quality by providing a power feeding means which compares a detection signal with a reference signal to detect a period wherein temperature corresponding to the reference signal level is higher than the temperature of a fixation part, and supplies electric power to the heating means of the fixation part during the period. CONSTITUTION:When the power source of a copying machine is turned on at time t0, 100% electric power is supplied from an AC power source 8 to the heater 9 until the temperature TS of the fixation part reaches lower-side temperature Tl, and the temperature TS of the fixation part rises speedily. When the fixation temperature TS reaches the lower-side temperature Tl at time Ta, the temperature further rises, but the duty decreases corresponding to the temperature DELTAT by which the fixation part temperature Ts exceeds the lower-side temperature Tl and the supply electric energy to the heater 9 decreases. The rising speed of the fixation part temperature Ts decreases gradually and converges on a balance point where electric power for obtaining a heating value equal to the heat radiation quantity at the fixation part is supplied. This balancing temperature is nearly equalized to target temperature Tm by selecting the waveform of a voltage Vr properly. Consequently, constant quality is obtained at all times without any variance in copy quality.
