Title: Connector coupling driver for sample box of spectral irradiating apparatus
Inventor: MATSUMOTO KOUICHI
IPC: G01N21/01
Filed: 1980-02-22
Abstract: PURPOSE:To obtain a connector coupling aparatus which is speedy, reliable and durable by a method wherein the position of the connector driving mechanism is accurately prescribed by using an absolute encoder, and the power supply to the sample box is delayed a fixed period of time after connectors have been coupled. CONSTITUTION:The signal of an absolute system encoder 39 is connected to a comparator 42, which compares the output value of the encoder 39 with the signal representing the wavelength axis feed amount under instructions from a controller 9. Then, detecting the difference, the comparator 42 instructs the drive direction and amount of a wavelength axis feeding motor 22 through a drive circuit 43, and when there is no more difference, the comparator 42 transmits the motor stopping instruction to the motor 22 and the signal representing coincidence to the controller 9. On the other hand, under instructions from the controller 9, an optical axis direction feeding motor 30 is operated through a drive circuit 44, so that a connector 28 is coupled with the connector 45 of a sample box. Then, via short terminals 40, a signal actuates a deciding and delaying circuit 46 to stop the motor 30 and supply power to terminals 48. Thereby, a reliable and durable apparatus can be obtained.

Title: Instantaneously set type hand crystal watch
Inventor: OOOKA MITSUO
IPC: G04C9/04
Filed: 1979-02-23
Abstract: PURPOSE: To accurately set the minute hand of a crystal watch to an accurate time by stepwisely shifting the hand on a minute scale at one minute pitch by turning a crown.  
     CONSTITUTION: When a knob 10 is pulled, a zero set lever 33 is turned to be engaged with a heart cam 32 to rotate the cam 32 to sort a second hand integral with a second shaft 25 in ±30 seconds so as to set to zero second. The second threaded cylinder 23 inserted fixedly into the second shaft 25 is simultaneoulsy rotated to rotate a minute transmission wheel 26, a minute wheel 27, a minute threaded cylinder 28, a day wheel 29 and an hour wheel 30 to set hour and minute hands secured to minute threaded cylinder 28 and hour wheel 30, respectively to zero. When the crown 10 is turned in this state, the cylinder 28 tends to rotate with respect to the minute wheel 27. Since a pawl 41 rides on the teeth of an index wheel 40 at this time, fingers gripping the crown feels resistance. When the pawl 41 rides over the crest of the teeth, force is applied in advancing direction of the crown. Thus, the cylinder 28 is stepwisely moved over one tooth of the wheel 40 to accurately correct the minute pitch of this watch.

Title: Gas stop device
Inventor: KOBAYASHI TOORU
IPC: F23N5/18
Filed: 1984-02-07
Abstract: PURPOSE:To confirm the open/close state from remote position by detecting the open/close position of knob and producing a signal indicating the open/close state.

Title: Information inputting device
Inventor: TAKAHASHI KENJI
IPC: G06F3/02
Filed: 1987-02-03
Abstract: PURPOSE:To improve the reliability of a device by previously setting up a time to be required from a data transmission request to a response, and when a response signal is not obtained within the set time and when a response signal is not proper, outputting a transmission request again. CONSTITUTION:A key input from a key matrix 1 is supplied to a control device 3 through an encoder 2. When the input information is a transmission request code, the control device 3 generates a transmission request command to a host interface part 7 and starts a timer 8. The timer 8 counts up the response time required from the transmission of the transmission request signal from the interface part 7 to a body device up to the reception of a response signal. When the time counted by the timer 8 is other than the previously determined set time and when the response signal is not a proper signal, the control device 3 outputs a transmission request command again. Thus, the reliability of the device can be improved.
