Title: Hot melt applicator with dripping- proof mechanism
Inventor: KUREIGU DONARUDO OSUTAA
IPC: B05C17/005
Filed: 1990-02-02
Abstract: PURPOSE: To prevent the dripping after dispensing of a molten material by coupling a feeding mechanism to a frame, including a retracting device and releasing device in the feeding mechanism and providing the releasing device with a sleeve and spring device. CONSTITUTION: An actuator 192 is pushed to close the arm part 168 of the feeding mechanism 154 and to advance a slider 156 together with a block 136 toward a melting chamber 118, thereby dispensing a molten adhesive from a nozzle orifice 134. As the block 136 advances, the tabs 109 and 111 of the releasing device 197 engages with the block 136 with the friction force sufficient for compressing a pair of springs 113. When the sleeve 105 arrives at the forward movement limit with respect to a housing 101, the forward pressure of the slider 156 overcomes the friction force by the tabs 109 and 111 and the springs 113 move the sleeve 105 backward with respect to the block 136.  When the forward pressure of the actuator 192 is released, the arm part 168 separates the block 136 and the springs 113 retreat the block 136 to the retraction position to hold a free floating state and move the block in a space 117.

Title: Device for measuring scan distortion in optical system
Inventor: TAJIMA MASAMI
IPC: G02B26/10
Filed: 1986-02-05
Abstract: PURPOSE:To automatically perform measurement by using a self-identifying circuit which controls automatically setting of a threshold value of an optical pulse signal in accordance with the pulse height in case of measurement of pulse intervals of a pulse scan signal. CONSTITUTION:With respect to output pulses of individual photodetectors D1, D2...Dn constituting a photoelectric photodetector array 3, detected optical outputs become electrical signals separated from one another with respect to time because the diameter of a light beam is sufficiently smaller than intervals of photodetectors. These pulses are cut by a certain threshold to find center positions of pulse width, namely, points corresponding to photodetector existing positions on electric pulses of photodetectors D1, D2...Dn, and respective values are plotted on two-dimensional coordinates to draw a scanning curve for the purpose of allowing them to correspond to geometrical positions of photodetector arrangement, and the linear scanning capacity of this optical system is discriminated. A self-identifying circuit 4 sets what fraction of the detected pulse peak value the threshold level is by a variable resistance VR at the beginning of this measurement though the intensity of a laser light is fluctuated and drifted and characteristics of photodetectors D1, D2...Dn or the like are not uniform.

Title: Automatic controller for impedance matching
Inventor: OGAWA MASAYOSHI
IPC: H04B3/03
Filed: 1989-02-03
Abstract: PURPOSE:To dispense with the setting of a corresponding leakage allowable level value at every transmission level by inserting a control tone to the transmission side of a four-wire line with a constant level outside the sound frequency band area, detecting the level of the control tone leaking to a reception side, and adjusting matching impedance so as to minimize the level. CONSTITUTION:The output of a control tone generation circuit 7 is set between 100Hz and 10dBm, and is connected to the transmission side of the four-wire line via a mixer 8. The control tone is superposed on a transmission signal 102, and it becomes the four-wire side input 104 of a hybrid circuit 1. The control tone 106 leaking to the four-wire reception side of the hybrid circuit 1 is inputted to a level detection judging circuit 6 via a band-pass filter 5. Then, no setting of the leakage allowable level value at every transmission level is required by performing impedance matching by a DC signal 107 corresponding to the level value, and adjusting the level so as to minimize the level of turn round of the control tone.

Title: Method for controlling output of semiconductor light emitting element and integrated semiconductor light emitting element
Inventor: TORIKAI TOSHITAKA
IPC: H01S5/026
Filed: 1992-02-13
Abstract: PURPOSE:To obtain a simple light output controlling method for a semiconductor module used for subscriber's optical communication and, at the same time, to reduce the size and cost of the module. CONSTITUTION:The driving current IL of a semiconductor laser 1 is controlled by connecting a photoconductive element 2 in parallel with the laser 1 and receiving the light emitted from the laser 1 by means of the element 2. Since the electric current IR flowing to the element 2 increases as the intensity of the light made incident to the element 2 becomes stronger, the inrush current IL to the laser 1 is controlled in accordance with the intensity of the light. Therefore, the fluctuation of the light output of the laser 1 caused by the variation of the ambient temperature can be reduced.
