Title: Light source device for endoscope
Inventor: KIDAWARA ATSUSHI
IPC: A61B1/06
Filed: 1987-05-13
Abstract: PURPOSE:To eliminate the need of each different kind of light source device of a scope, and different operations, and to improve the profitability and the efficiency by providing an optical system which can select an optical path for reaching an object, after having transmitted through a color filter, and an optical path for reaching the object, without transmitting through the color filter. CONSTITUTION:A discriminating circuit 28 not only controls both drivers 26a, 26b but also controls switching of a changeover switch 103. For instance, when a face sequential scope 2A or 2C is connected, the switch is switched to the face sequential side, a driving pulse of the driver 26a is applied to a solid-state image pickup element 18 through a connector, and also, a signal which has been read out of the solid-state image pickup element 18 is inputted to a face sequential process circuit 41a. On the other hand, when the face sequential scopes 2A, 2C are not connected, a mosaic type process circuit side is selected, and can be used as a light source of a fiber scope, as well. In such a way, an illuminating light conforming to a scope provided with a face sequential type or a color mosaic type, and a fiber scope being capable of a visual observation can be supplied, and the efficiency can be improved.

Title: Servo amplifier
Inventor: SHINODA SEIJI
IPC: H02P29/00
Filed: 1991-04-22
Abstract: PURPOSE:To decrease the number of wirings set between a servo motor and a servo amplifier by performing the positioning control with the use of a Z-phase signal while outputting the external device including a host device. CONSTITUTION:When an original point returning command is received from a host device, a servo amplifier drives a servo motor 10 at a high speed to move a positioning object toward an original point. Then the driving speed of the motor 10 is slowed down to a low level (creep velocity). When the LS signal is turned off, a Z-phase signal is obtained from the pole position signal sent from a pulse encoder. A point where the Z-phase signal is detected is defined as an original point and the motor 10 is stopped. That is, a fact that the pole position detecting signals necessary for the control of the motor 10 are outputted three times per one revolution of the motor 10 is utilized for the detection of one of these three detecting signals as a Z-phase signal. This detected Z-phase signal is used for the positioning control.

Filed: 1987-05-15
Abstract: PURPOSE:To suppress the increment of the number of parts due to the increment of decoding circuits as small as possible by forming a circuit for assigning inherent codes to at least a part of a storage circuit group.

CONSTITUTION:When a heating operation is to be performed, at first, a room temperature sensed by a sensor 29 is read into CPU 24 through an input circuit 23 so as to determine reference air blowing output step numbers (m), (n) of an upper fan motor 18 and a lower fan motor 19. Then, a presence or an absence of the input of a switch part 28 is discriminated, and in case that a switch input is present, it discriminates that 'hot' switch is inputted or 'cold' switch is inputted. A value of the number of reference blowing air step (m) of the upper fan motor 18 is decreased by one step, an output from the upper fan motor 18 is decreased without changing a reference blowing air output step number of the lower fan motor 19, an output of the lower fan motor 19 is not varied, and then an air blowing capability of the upper blower 14 is decreased. That is, when heated, a blowing air capability of an indoor blower is decreased, thereby a pressure in the heat exchanger 12 is increased and the temperature increases, so that the temperature of air blown from the upper blowing port 15 and the lower blowing port 17 increases.

Filed: 1981-07-28
Abstract: PURPOSE:To completely eliminate the leakage component through an LPF at a back stage, by increasing the frequency for the leakage component of a sampling clock signal to separate it from the frequency of an input signal. CONSTITUTION:A sample holding circuit 40 contains two sample holding circuits 41 and 42 which are connected longitudinally to each other. The circuit 41 samples and holds an input signal with a sampling clock signal having a sampling frequency fO approximate to the frequency of said input signal. This output signal is sampled and held again by the circuit 42 with a sampling clock signal  having a sampling frequency n f0. Thus an output signal is obtained. As a result, the leakage component of a signal f0 contained in the output of the circuit 41 has a big difference of frequency to the output signal of the circuit 42. This leakage component can be easily eliminated through an LPF at a back stage.

Abstract: PROBLEM TO BE SOLVED: To simple control to have a prescribed coating film thickness even if the dipping time in a solution bath is short by specifying the time until the finish of liquid removing after a material to be treated is taken out from the solution bath to the dipping time in the solution bath. SOLUTION: The time until the finish of liquid removing is controlled to >=4 times of the dipping time. Preferably the time until the finish of liquid removing after the discharge from the solution bath is controlled to 4-12 times of the dipping time in the solution bath and the ambient environmental temp. in the time until the finish of the liquid removing after the discharge from the solution bath is controlled to be lower than the temp. of the material to be treated and the gas flow rate is controlled to 40-55 m/sec. For example at the time of treating a wire 5, a gas is blown to the outer peripheral surface of the wire 5 in the longitudinal direction and the reverse direction to the advancing direction of the wire 5 and a remaining treating liquid 6 is pushed to the longitudinal direction to be removed.  As a result, the wire 5 and the liquid 6 at a high temp. are cooled while uniformly removing the treating liquid 6 with a sufficient time and then, a coating film forming component is super saturated to be deposited again and a coating film having the prescribed thickness is obtained. Then the wire drawing property in a dry wire drawing process is remarkably improved.

IPC: G01T1/24
Filed: 1986-05-23
Abstract: PURPOSE:To put the output of a detector within a proper range even when the conditions of plasma change by varying the diameter of the hole of a collimator according to the output of the detector. CONSTITUTION:An X ray emitted by plasma 1 is transmitted through an absorbing film 3, a soft X ray 9 radiated from an end part of the plasma by the collimator 2 is detected by a detector 4b, and a soft X ray 9 emitted from the center part of the plasma is detected by a detector 4b. Outputs of plural detectors are inputted to a computer 5 and a controller 6 to decide whether or not the outputs of all the detectors are within the set range. If even one output is larger than the set upper limit value, the diameter of the hole of the collimator is reduced and when less than the set lower limit value, the diameter of the hole is increased. Further, the spatial resolution varies with the diameter of the hole of the collimator, so a signal 8 is inputted from the device 6 to the computer 5 and corrected to put the outputs of the detectors within the proper range.
