Title: Back and forth running type cassette tape recorder
Inventor: MIKI HISAHIRO
IPC: G11B15/60
Filed: 1985-02-15
Abstract: PURPOSE:To enable the stable running of a tape even when the pressure contacting point between a capstan and a pinch roller is on the tape supplying side by providing a tape guide along a part of outer circumference of a pinch roller. CONSTITUTION:A tape guide 5 having an arc approximate to a roller 4 is placed in a part of the pinch roller 4 of a tape recorder that makes back and forth running by a set of a capstan and a pinch roller, and side walls 5a and 5b are formed on its both sides. When a tape 2 runs to the left shown by an arrow, the pressure contacting point between the capstan 3 and pinch roller 4 comes to the upstream side, that is tape supplying side. However, as the tape 2 is guided by side walls 5a, 5b, pushing up and pushing down of the tape are not caused. Accordingly, the tape can be run both ways stably even when a set of capstan and pinch roller is used.

Title: Surge voltage protecting circuit
Inventor: IKUTO YOSHIHIRO
IPC: H02H9/04
Filed: 1993-02-16
Abstract: PURPOSE:To obtain a surge voltage protecting circuit in which an internal electric circuit can be effectively protected without damaging it against a high surge voltage. CONSTITUTION:When a positive surge voltage is applied to a power source terminal 31 and a voltage across a Zener diode 36 exceeds a predetermined threshold value level, the diode 36 is conducted, a surge current flows, and a transistor 37 and a transistor 42 of a holding circuit 35 are turned ON. Thus, most of the surge current is bypassed to a power source terminal 32 between a collector and an emitter of the transistor 37. A transistor 41 is turned ON due to ON of the transistor 42. Thus, even after the surge voltage becomes a threshold value level or less, part of the surge current is supplied to a base of the transistor 37 between an emitter and a collector of the transistor 41, and hence the transistor 37 holds the ON state, and the surge current is effectively bypassed.

Title: Evaluation of molding performance of injection molder and applicator of flow resistance therefor
Inventor: MATSUKI SHUNSUKE
IPC: B29C45/76
Filed: 1986-02-12
Abstract: PURPOSE:To make it possible to evaluate the molding performance of an injection molder without utilizing a mold by a method wherein, first, the changing pattern of resin pressure developed when resin is actually injected in a mold and then the flow resistance of the molten resin flowing through an injection nozzle is changed at injection so as to change the resin pressure in the nozzle in order to give the load change same as given when the molten resin is actually injected in the mold. CONSTITUTION:The evaluation of the molding performance is done by injecting molten resin in the atmosphere through an injection nozzle 1 mounted on an injection molder to be evaluat ed. When injection action is started, a control signal is outputted from a controller 10 so as to rotate a servo motor 7 in order to bring the opening of a valve 3 to q1 after the period of time t1. When the time t1 is reached, the control signal sent from the controller 10 is changed over to a signal, which brings the opening of the valve 3 to q2 at the time t2. By repeating the changing-over of signal as mentioned above, the servo motor 7 actuates in accordance with a set pattern. Because the above-mentioned change of the opening of the valve 3 causes the change of the flow resistance of molten resin flowing through the nozzle 1, the resin pressure in the nozzle 1 is changed so as to give the load change same as given when the molten resin is actually injected in the mold to the injection molder to be evaluated actually.

Title: Detector for width and zigzag movement of laminar object
Inventor: HASHIMOTO SUNAO
IPC: G01B11/245
Filed: 1981-02-27
Abstract: PURPOSE:To provide a detector which is resistant to disturbances such as vibration  and dusts and has a wide measuring range for width of a laminar object, by a method wherein, in the detection of the width and zigzag movement of the laminar object, a  projector for width of the laminar object, reference projectors, and collectors are  mounted appropriately. CONSTITUTION:A projector 12 for width of a laminar object is placed below a laminar object 10 to be conveyed and in a direction crossing a conveyance direction at right  angles, and reference projectors 13 are located at opposite ends thereof. Each of the  irradiation ports 11 and 14 of the projectors faces upward. Light collectors 16 provided with photoelectric elements 15 having their respective numbers of bits are predetermined so that their light collecting areas are overlapped at a central position. Because, the irradiation ports 14 are positioned in the approximately same level as that of a conveyance line, dusts are made to be difficult to enter. Additionally, the plural number of the light collectors are mounted, thereby a light collecting area is prevented  from deviating to cover a conveyance path even if the collector inclines due to vibration. The overlapping of the light collecting areas allows to perform sufficient detection even if a laminar object with a narrow width being less than a half a conveying device is conveyed in an one-sided manner.

Title: Transceiver
Inventor: MATSUO MITSUAKI
IPC: H04B1/38
Filed: 1994-01-31
Abstract: PURPOSE:To prevent the confusion of transmission time due to the limit of maximum continous transmission time. CONSTITUTION:The time from the time when a transmission switch 20 is depressed is timed, and when the switch is operated continously before 30 seconds, a notification sound signal is transmitted. Thus, continuous transmissions over thirty seconds are notified to a reception side. In this case, when the reception side receives the notification sound signal, a transmission operation is invalidated for prescribed time over 2 seconds from a point of time and this period becomes a reception state. As a result, because this operation is invalidated even when the transmission switch 20 is erroneously depressed within prescribed time after the notification sound signal is received and the transmission switch 20 is depressed by ignorance, the transmission continuation on an opposite side can be surely notified.

CONSTITUTION:Tapered inner side of clamp dies 20 is put on the tapered part of a joint, and a hydraulic pushing ram is extended. A pushing arm 7 advances and a pin 6 rotates the jaw part 1 around an axial pin 4. Then, clamp dies 20 and compression dies 23 are brought close to each other and hold the joining part of the tubes. When the hydraulic ram 27 is further extended, the pushing arm 7 advances along a long hole 5 through the pin 6, and pushes an outside slanted face 12 with the slanted face of a cam pushing plate 9. In this way, an angular ring of the cam is slid on the inner side of the jaw part 1 and presses slanted faces 18, 19 of clamp dies 20 and slanted faces 21, 22 of compression dies 23, and brings both dies 20, 23 close to the axial direction of the tubes to be joined. Consequently, the tip of joined part of the joint is pushed to inside of the  tapered part of the compression dies 23 which became annular by close contact. Thus, joining work is completed.
