Title: Field-effect transistor and its manufacture
Inventor: HORI KYOKO
IPC: H01L29/812
Filed: 1992-01-31
Abstract: PURPOSE:To obtain a uniform threshold voltage by reliably executing the control of the threshold voltage by the wet etching which has hitherto been difficult for a field effect transistor and in its manufacture method. CONSTITUTION:In the structure of a recessed type field effect transistor, an AlAs layer 15 is formed as a recess etching suspension layer on an electron supply layer 14 in the 2DEGFET or on the operation layer in the MESFET. Hence, when a wet etching is executed, it is possible to obtain a uniform threshold voltage in a wafer without etching the electron supply layer 14 or the operation layer under a contact resistance reduction cap layer 16. Also, it is possible to easily and selectively etch the AlAs layer 15 immediately before the formation of a gate electrode 19. Therefore, the movement of electron from the gate electrode 19 to the electron supply layer 14 is not hindered, either.

Title: Emergency retreating device of cathode ray tube in recording apparatus
Inventor: ISHIKAWA CHIYUUJI
IPC: G03B27/32
Filed: 1979-02-15
Abstract: PURPOSE: To make possible the rapid retreating of the cathode ray tube at the abnormality by emergently retreating the cathode ray tube from recording position by way of a solenoid or the like which is energized by abnormality detection output.  
     CONSTITUTION: A base plate 10 which clamps a cathode ray tube 1 is moved to the retreat position by a drive lever 31 operated by the cam follower 24 whose detention is released by a disc 23 turned by the switch operating upon ending of recording, a cam 22, slide plate 32, reset lever 35, etc. and a driven lever 18 interlocking with this, whereby the occurrence of staining of the front surface owing to the flying toner at the development processing of photosensitive drum is prevented. This retreating is similarly accomplished by turning of the lever 35 and releasing of stopping of the follower 24 when a solenoid 39 is energized by the abnormality signal. Hence, even if jam or the like occurs during latent image recording, the cathode ray tube rapidly retreats together with the base plate, thus the staining of the front surface of the cathode ray tube by the toner or the like is obviated.

Title: Method and mechanism foor feeding material web
Inventor: GIACOMELLI PETER
IPC: B65B41/18
Filed: 1987-01-27
Abstract: In the stepwise feeding of a packing material web for the application of cover strips over prepunched pouring openings, the pouring opening is sensed by means of a photocell which is located as long before the point of application as the distance between two pouring openings. Any errors in this distance will thus affect the accuracy of application. In order to avoid this it is proposed in accordance with the invention to sense the passage of the actual pouring opening and start a countdown sequence, at the end of which the web feed is interrupted with the pouring opening in correct position for the application of the cover strip. An arrangement for the realization of this, seen in the direction of feed of the material web (1),comprises a sensing device (4), a processing device (5) and a forward feeding device (9) which are connected to a control unit (13)
