Title: Plate-shaped material holding apparatus
Inventor: HASHIMOTO TAIZO
IPC: B65H3/14
Filed: 1986-12-26
Abstract: PURPOSE:To obtain a holding apparatus, which can prevent the damages and the yield of dust of a plate shaped material, by providing a pushing-force generating part, which generates a force that pushes the plate-shaped material held by a head in the arbitrary engaging direction. CONSTITUTION:A fluid is made to blow to a plate-shaped material 1, or the fluid is sucked through a sucking surface. A stream layer is formed between the plate-shaped material 1 and the sucking surface in this way, and balance is provided between the sucking pressure and the flowing pressure. A head 12 sucks and holds the plate- shaped material 1. A plurality of engaging parts 5 are arranged so as to about on the side surface of the plate-shaped material 1, which is sucked and held with the side surface of the head 2. A pushing-force generating part 16 generates a force, which pushes the plate-shaped material 1 held by the head 2 in the direction of the arbitarry engaging parts 5. Said pushing-force generating part 16 inclines, e.g., the head 2 with respect to the horizontal direction. Thus a force of component F in the direction in parallel with the sucking surface of the head 2 is energized on the plat-shaped material 1. Thus the frequent hitting phenomenons of the plate-shaped material to a guide can be suppressed, and the damages and the yield of dust of the plate-shaped material can be prevented.

Title: Photoelectric encoder
Inventor: MIZUMOTO YUKIHIRO
IPC: G01D5/36
Filed: 1990-11-14
Abstract: PURPOSE:To enable increase in size and price of a device to be restricted and resolution to be improved by allowing an array pitch of a light-transmission part of a scale or a light-reflection part to be equal to or less than a specified multiples of array pitch of a light-receiving element at the light-receiving part. CONSTITUTION:When a scale slit pitch P is set to a relationship of P=4XD/(2+n) (n: positive integer) for a pitch D of light-receiving elements PDa, PDb, PDa', and PD'b, 4/3 multiple of the pitch D is equal to the pitch P in the case of for example n=1. At this time, output signal levels Va, Va', Vb, Vb' of elements PDa, PDb, PDa', and PDb' fluctuate with the pitch P as one cycle, phase is inverted between Va-Va' and Vb-Vb' and there is a phase difference of 90 degrees between Va-Vb and Va' and Vb', thus obtaining binary signals VA and VB with a phase difference of 90 degrees by comparing Va and Va' and Vb and Vb'. In the case of n=1, the pitch P becomes thinner by a factor of three, thus obtaining a triple resolution even if the pitch D is the same. Similarly, 5-times resolution can be obtained in the case of n=2.

Filed: 1987-12-09
Abstract: PURPOSE:To simply execute the calibration, and also, to quickly and exactly execute the temperature measurement by providing an opaque heat insulating material on the end part of a CCD element. CONSTITUTION:The title instrument consists of a CCD element 1, an opaque heat insulating material 2 provided on the end part of the CCD element 1 by a method of vapor-deposition, etc., a Dewar vessel 3 for containing them, and a pipe 4 for supplying nitrogen to the inside of the Dewar vessel, and the inside of the Dewar vessel 3 is held at an absolute temperature 77 deg. by sealing up tightly nitrogen. In such an instrument, when a scan is executed in the direction as indicated with a symbol 5, an output signal A is obtained. In this case, since the heat insulating material 2 is opaque, no infrared ray nor light from a measuring object is allowed to pass through. Also, since the heat insulating material 2 is held at the absolute temperature 77 deg., the part of the signal A is a level corresponding to the absolute temperature 77 deg.. When a reference temperature point which is calibrated in such a way is determined, the temperature of other part can be determined, based on the reference temperature point. In such a way, the calibration can be executed exactly and the temperature measurement can be executed quickly and exactly without necessitating a special operation.

Filed: 1994-11-18
Abstract: PURPOSE: To reduce an equipment cost and running cost and to suppress the adverse influence on the environment by improving the efficiency of a system for cleaning exhaust air containing solvent vapor. CONSTITUTION: The exhaust air is sucked out of a working chamber 2 and is sent to active carbon adsorbers 10 to 13 which are arranged in juxtaposition. Each adsorber can be switched to a charging mode in which the absorber adsorbs the solvent vapor and a regeneration mode in which the solvent vapor is separated from the flow of the exhaust air and flushed with the water vapor and absorbed. The end of the regeneration period of each adsorber has a drying phase, i.e., the drying phase which joins the exhaust air from the working chamber to the inlet side of another adsorber during the operation in the charging mode. The beginning of the period when the adsorber operates in the charging mode is provided with an initial stage so as to shift into the main stage and to return the flow of the air from the adsorber in the main stage directly to the working chamber.  On the other hand, the flow of the air from the adsorber in the initial stage is kept separated from the flow of the air from the adsorber in the main stage.

Title: Picture forming device
Inventor: AKIYAMA YASUHISA
IPC: G06T3/40
Filed: 1989-11-29
Abstract: PURPOSE:To form a picture with satisfactory picture quality by simple configuration by processing a picture signal corresponding to a magnification to form the picture and calculating plural coefficient based on values for the prescribed number of bits. CONSTITUTION:When the enlarging magnification is set, density data corresponding to chrominance signals are processed according to a linear interpolation method by a magnification processing circuit 97 and when the reducing magnification is set, the density data are processed according to a projecting method. Therefore, since the density data are processed corresponding to the copying magnification, the generation of moire, etc., can be prevented. Parameter data are generated by using the four bits (DPOS) less than a decimal point of a position calculated result to be outputted from a read position calculation part 103 and the read position of the density data is controlled by using an integral part (PINC). Thus, accuracy is improved for the read position corresponding to the copying magnification, the number of the coefficients to be used for calculating the density data can be decreased and the circuit configuration is simplified.

Title: Amplifeir, transmission circuit and reception circuit
Inventor: ABE MASAMI
IPC: H03G3/30
Filed: 1996-11-06
Abstract: PROBLEM TO BE SOLVED: To reduce power consumption and gain fluctuation, when input/output are low by connecting the multiple stages of active elements in parallel, switching bias voltage/current given to them and sequentially switching the desired number of elements from those of low gains to non-active ones. SOLUTION: An amplifier 22 is constituted by connecting the multiple stages of FET groups 27 and 28 in parallel. The gate length or the gate finger width of the group 27 is set to be small and that of the group 28 to be large. When high output is transmitted and when a received signal intensity is in a low level, the groups 27 and 28 are set in an operational state. When low output is transmitted and when received signal intensity is in the low level, a switch 37 is changed over, and the group 28 whose gain is low compared to that of the group 27 is set to an off-state. When low output is transmitted and when received signal intensity is in the low level, power consumption can be reduced, and the range of gain fluctuation is set to be small so as to reduce the discontinuity of the gain.  Thus, the stability precision of output power and the gain can be improved by a simple constitution and control.
