Patent JP-H0272689-A (JP)
Title: Semiconductor laser
Inventor: HIRATA SHOJI
IPC: H01S5/00
Filed: 1988-09-07
Abstract: PURPOSE:To improve the characteristics, reliability and yield of elements by combining a rib waveguide as a refractive index waveguide mechanism and an embedded heterostructure as a current narrowing mechanism. CONSTITUTION:In a rib waveguide, the central region of a guide layer 25 is thickly formed in a stripe shape. A width w4 is wider than a width w3 of the rib waveguide. An embedded region 33 comprising the same crystal structure as those of clad layers 22 and 34 is formed on both sides of an active layer 24 and the guide layer 25. In this structure, a current is narrowed in the range having the width w4 based on energy gap difference. A current having a low threshold value is obtained. Meanwhile, light is confined in the rib waveguide having the width w3(<w4). Therefore, light scattering is not generated even if wrinkles due to etching are formed on the side surface of the mesa part having the width w4. The width w3 can be readily controlled because the rib waveguide is used. The device can be fabricated by the two crystal growings. Thus the reliability and the characteristics of the element can be improved, and the yield rate can be enhanced.

Title: Number of coin feed controller for vending machine
Inventor: MIYAZAWA TADASHI
IPC: G07F5/22
Filed: 1987-09-07
Abstract: PURPOSE: To secure vending chances to the maximum by not driving a coin throw-in rejecting device unless a coin tube is full even if a previously set upper-limit value is exceeded. CONSTITUTION: For example, the previously set upper-limit value for 10-yen coins is set to 20 and when the number of coins stored in the coin tube 7 is 25, 20 coins are thrown in. In this case, since the number of thrown-in coins does not exceed the previously set upper-limit value, a comparator outputs a low-level signal. Further, the tube 7 becomes full, so a detection switch 10a sends a high-level signal out to a judging circuit. Since the judging circuit outputs a low-level signal, the coin throw-in rejecting device is not driven. When 5 coins are stored in the tube 7 and 15 coins are stored in a cashbox. When thrown-in coins are requested to be return, 20 coins are returned from the tube 7 and 10 coins are left in the tube 7.

Title: Charge storage type telephone set
Inventor: OSADA HIROSHI
IPC: H04M17/02
Filed: 1985-10-09
Abstract: PURPOSE:To detect coins in a wait state after a called subscriber answers without using any special contact nor part for coin detection by using a contact CC 1 as a detection contact. CONSTITUTION:The 1st coil is stored according to the response of the called subscriber, but if there is further a coil in a wait state, the contact CC 1 is made and 'L' is supplied to CNT 5 through a resistor R 3 to judge that the CNT 5 further allows a call. When all coins are stored, on the other hand, the contact CC 1 is broken and the CNT 5 controls a SWC 2 a unit call time after the last coin storage point of time and turns it off to cut off the call forcibly. When the telephone set terminates, a current in the operation direction to a relay ANS flows through a diode D 6 and a hook switch HS<2> and the relay ANS holds operation to allow the contact CC 1 to be by-passed through a contact ans<0>, so as answer call becomes free without requiring any coin.
