Title: Output circuit
Inventor: SHIMIZU SHOICHI
IPC: H03K19/0185
Filed: 1988-10-31
Abstract: PURPOSE:To increase a current capacity and to reduce a gate width by securing such a constitution where an FET which directly drives a termination resistance has the threshold voltage lower than that of another FET. CONSTITUTION:The open drain FET Q20 and Q21 and a current source FET Q22 have the threshold voltage levels of about -0.6V lower than the threshold voltage level of about -0.2V of other FET Q1, Q2, Q8 Q9, etc., of an internal circuit. Thus an output circuit consists of the FETs having different threshold voltage levels. In this respect, the bias circuits using the FETs of the same characteristics are set to the FETs having different threshold voltage levels respectively in terms of the matching properties of the element characteristics. The output waveform of the output circuit has the improved rise characteristics compared with the conventional output waveform. For instance, the output waveform of this new output circuit suffices with about 30ps against about 40ps required for the conventional waveform in terms of the output waveform levels 20-80%.

Title: Developer applicator
Inventor: KAGAYAMA SHIGERU
IPC: G03D13/00
Filed: 1989-10-23
Abstract: PURPOSE:To efficiently apply a large quantity of developer toner by providing a vibration layer formed by a piezoelectric body on a part of a carrying roller, and applying an alternating electric field. CONSTITUTION:The vibration layer 28 formed by the piezoelectric body is provided on a part of the carrying roller 26, and an alternating electric field is applied. Since the vibration layer 28 formed a the part of the carrying roller 26 vibrates under the alternating electric field, developer toner can be separated from the groove wall of the carrying roller 26. Therefore, a large quantity of developer toner can splashed from the inside of the grooves. Thus, high speed coating with a large quantity of developer toner, which was impossible previously, can be achieved by efficiently coating with it.

Title: Data recorder
Inventor: KOBAYASHI MASAHIDE
IPC: G01D3/02
Filed: 1989-10-25
Abstract: PURPOSE:To accurately plot a peak value without the break of a waveform and to plot an AC waveform faithfully to an original waveform by plotting all the data on a graph even in the case that the data is plotted after being compressed in a time base direction. CONSTITUTION:A central processing unit CPU 6 calculates a time tau equivalent to the length of minimum unit in the time base direction by a following formula. tau=DELTAl/S. Provided that DELTAl means the length of the minimum unit which can be plotted by a plotter 4 and S means the length per unit time in the time base direction of a chart. Next, the plotter 4 is designated that the last data one row before in the time base direction and the first data of the time base of this time are connected with a line. Furthermore, supposing that the sampling interval of the data is DELTAt, whether tau is smaller than the M-fold(M is an integer) of DELTAt is checked to confirm whether the data is within a plotting cycle tau. When the data is within the cycle tau, the data are connected with the line on the same row and when the data exceeds the cycle tau, control is performed to shift to the next row.

Title: Liquid sealed type differential pressure transmitter
Inventor: MASUDA HISAYOSHI
IPC: G01L19/06
Filed: 1984-12-28
Abstract: PURPOSE:To improve reliability by arranging a pressure receiving diaphragm, an overpressure preventing mechanism, and an annular diaphragm coaxially while aligning them to the center of a body. CONSTITUTION:When pressure PH to be measured becomes excessive, the pressure PH is impressed to the outside of a bellows 22 through the pressure receiving diaphragm 21a and a pressure transmission medium 28a. When this excessive pressure is received, the bellows 22 moves to right and a valve rod 24 and valve parts 23a and 23b also move to right reacting to the motion. Then, the valve part 23a contacts the valve seat 29 of the body 20 to inhibit the medium 28a from moving. Namely, the movement of the medium 28a is inhibited to stop subsequent pressure transmission and the excessive pressure is never transmitted to a pressure sensitive element part 27. Further, if the temperature varies while the movement of the medium 28a is inhibited, differential pressure is generated owing to the thermal expansion of the media 28a and 28b, but this differential pressure is absorbed by an annular diaphragm 30. Differential pressure generated by thermal expansion while over pressure is prevented is not supplied to the element part 27 either.

CONSTITUTION:A minimum delivery window 32 for delivering one of single crystals 9 is formed in a clean room 31 to attach a door 33. For delivering the single crystal, a worker who enters the clean room 31 opens the door 33 of the delivery window 32, and pushes out the single crystal 9 in the arrow direction A, and then transmits it onto a cart 10 by a feed means 22 in a longitudinal direction. A feed means 16 in a lateral direction is driven, and the single crystal 9 is moved in the arrow direction B in one pitch. The second single crystal is pushed out in the same manner for lateral movement. This procedure is repeated in prescribed times. It is thus possible to minimize the delivery window and retrain cleanness deterioration to the minimum.
