Title: High-tension insulated gate type field-effect transistor
Inventor: SAITO MIKIKO
IPC: H01L29/78
Filed: 1984-09-26
Abstract: PURPOSE:To obtain a high-tension NMOSFET having a short channel by forming a low impurity-concentration source layer having the same conduction type as an offset gate region between a source layer and the channel while being brought into contact with the source layer, shaping a gate through an insulating film extending over the low impurity-concentration source layer and the channel and thinning a film on the low-concentration source. CONSTITUTION:A P<+> ground leading-out layer 8 and an N<+> drain layer 5 are formed to a P type Si substrate 1 through a conventional process, and B and As are implanted to shape a P buried ground 9 and an N<+> source layer 10. SiO2 16 and Si3N4 18 are laminated, a resist mask 19 is formed, and N type offset region 6 and low-concentration source layer 7 are formed through ion implantation. Si3N4 18 is left only to a layer 7 section and a gate oxide film 17 is shaped, and the film 18 is removed and a poly Si gate 4 is formed extending over the layer 7 and a channel 20, thus making the oxide film 16 on the layer 7 thinner than the film 17. A high-tension NMOSFET is completed according to a predetermined method. Channel length LE can be formed according to a desired value by the length of the layers 6 and 7. When the length of the layer 7 is brought to 3mum or more and the thickness of the film 16 is selected in approximately 500Angstrom , the high-tension NMOSFET having a short channel is shaped with high reliability.

Filed: 1982-11-16
Abstract: PURPOSE:To facilitate easy control of the distance between an image forming optical system and a writing surface by securing a free movement of a frame stored in another frame toward an optical axis while a holding means holds an optical system and an optical switching member and displacing said holding means by a displacement means. CONSTITUTION:The light of a light source lamp 11 is condensed by a condenser lens and illuminates the element array part of an optical switching element array 13 in a slit form in the lengthwise direction of said element array part. Under such conditions, the light is transmitted. Thus the writing position on the wiring surface is illuminated by the function of an image forming optical system 2 in the direction vertical to a drawing with a straight line form of small width. A cam driving shaft 55 is shifted in the lengthwise direction by a knob 58, and a holding means 3 is displaced toward the optical axis via a roll 52 and a sloping surface of a cam 51 displacing incorporatedly with the shaft 55. Then the control is carried out to minimize the width of the linear illuminating part to realize the correct positional relation between the system 2 and the writing surface. The displacement means contains the cam 51, the roll 52, a shaft 53, an elastic member 54, a cam driving shaft 55, a stopper 57'', a spring 57', bearings 56 and 59, a control screw 57, a knob 58 and a guide (not shown in the diagram) respectively.

Title: Picture recording/reproducing device
Inventor: TAKEUCHI KAZUHIRO
IPC: G06F3/06
Filed: 1999-07-15
Abstract: PROBLEM TO BE SOLVED: To provide a picture recording/reproducing device which can easily manage information recorded in a recording medium by reproducing the picture data of a picture file designated by a user when the comparison results of a password comparison/decision part are matched. SOLUTION: When a user designates a picture file to be reproduced from an input control part 44, a signal for reproducing the picture file designated from the input control part 44 is inputted to a system control part 42. The system control part 42 requests the user to input a password corresponding to the designated picture file through a display control part 45. A password comparison control part 43 compares the password inputted from the user with a password which is read by the system control part 42 and decides whether the password inputted by the user corresponds to the picture file that the user designates. When the decision results of the password comparison/decision part 43 are matched, a drive control part 41 reproduces the picture data of the picture file that the user designates.

Patent JP-H05193132-A (JP)
Title: Jet record method
Inventor: INUI TOSHIJI
IPC: B41J2/05
Filed: 1992-07-28
Abstract: PURPOSE:To carry out high speed stable recording with constant discharge by heating record medium so as to discharge the recording medium from a discharge outlet by means of bubble generated in the record medium and performing preheating before heating so as to make the generated bubble communicate with the outside air. CONSTITUTION:When current is supplied to a heater 2 momentarily and a record medium 3 arranged near the heater 2 is heated with pulsation, the medium 3 boils rapidly, generates a bubble 6 vigorously, and begins to expand. The bubble 6 continues to expand, particularly grows to a discharge outlet 5 whose inertia is small, further, goes through the discharge outlet 5 so as to communicate with the outside air. The recording medium 3 at the side of the discharge outlet 5 rather than at the side of the bubble 6 flies out forward due to momentum given from the bubble 6 before this moment and soon becomes an independent droplet so as to fly to a material to be recorded such as paper. After the medium 3 flew out, a cavity generated in a tip of a nozzle 15 is filled with a new medium 3 due to leaks of surface tension of the medium 3 at the back and the wall of the nozzle, thereby returning to a state before the discharge. Thus, since the bubble communicates with the outside air at the discharge of the medium 3, the droplet attaches to an aimed point correctly.

IPC: H02B1/56
Filed: 1994-08-26
Abstract: PURPOSE: To reduce the quantity of heat inside a control panel by providing a heat sink in a cooling duct inside the control panel and by cooling the heat sink forcedly by circulating outside air by forced convection. CONSTITUTION: By the rotation of a cooling fan 53, outside air is sucked into an air passage of a cooling duct 20 from a lateral air vent 3A of a control panel 101 (an arrow (c)). A radiation fin 61B of a heat sink 61 is cooled forcedly by an outside air flow and the warmed oar air is exhausted upward from a ceiling air vent 4a. Most of the heat from semiconductor modules 60 is conducted to a base plate 61A of the heat sink 61 and discharged immediately outside the control panel 101, while the heat sink 61 is cooled forcedly and directly by the outside air of low temperature. Since a temperature difference between the outside air and the heat sink 61 is large, heat dissipation is large and a temperature rise can also be lessened. According to this constitution, the quantity of heat inside the control panel 101 can be reduced.
