Title: Field effect semiconductor device
Inventor: YAMANAKA EIJI
IPC: H01L29/80
Filed: 1986-12-16
Abstract: PURPOSE:To form a field effect semiconductor device having electrically normally OFF characteristic by burying a stripe-or mesh-like gate layer having an impurity density higher than a drain layer and a source layer in the same conductivity type as the drain layer in an intermediate layer of conductivity type reverse to the drain layer. CONSTITUTION:A P<+> type ohmic layer 3' interconnected to a P-type intermediate layer 3, a stripe-or mesh-like N<+> type gate layer 4, an N<+> type gate ohmic layer 4' interconnected to the layer 4, an N-type source layer 5, and an N<+> type source ohmic layer 6 are formed. A drain current is stopped to the value of the dielectric breakdown voltage of a PN<-> junction J1 so as not to flow by an NPN<-> structure made of the layers 5, 3 and 2 in the state that a voltage is not applied across the layers 4 and 3. That is, it is a normally OFF. When a reverse bias voltage is applied across the layers 3 and 4, a voltage value for blocking an ID (drain current) gradually drops to obtain an I/V characteristic. Even if the stripe-or mesh-like P<+> gate is buried in the N-type layer in the PNP structure, a normally OFF characteristic can be provided.

Title: Transformer
Inventor: MATSUMOTO TAKAHIRO
IPC: H01F41/06
Filed: 1988-11-25
Abstract: PURPOSE:To make supporting force stable against the irregularity of core measurements, and to prevent the generation of abnormal noise due to vibration of the core and a metal fitting by a method wherein a locking means is formed in U-shape having protruding parts which are fitted in the recessed parts of a core, and the locking means is constructed in such a manner that all the parts excluding the protruding parts do not come in contact directly with the rear of the core. CONSTITUTION:Cylindrical recessed parts 11 and 12 are provided on ferrite cores 9 and 10. The protruding parts 14 and 15 of a locking means 13 are fitted into the recessed parts of the cores and the cores are supported. The looking means 13 is made of elastic phosphor bronze, and as it is a non-mangnetic body, the degree of induction heating by high frequency is low. As the distance lbetween the working points 20 and 21 of the locking means 13 makes almost no change even when the measurements of the ferrite cores are irregular, the cores can be supported with stabilized strength. Also, as the locking means 13 does not come in contact with the ferrite cores 9 and 10 on the part other than the recessed sections 11 and 12, the light contact of the locking means with the core, which becomes the cause of abnormal noise, can be prevented.

Filed: 1998-10-20
Abstract: PROBLEM TO BE SOLVED: To improve the operating speed of a logic circuit by reducing the capacitance between a gate electrode and a diffusion layer by providing air gaps having the smallest dielectric constant on the side faces of the gate element. SOLUTION: After a field oxide film 2 is formed in the surface of a silicon substrate 1, a gate insulating film 3 is formed on the surface of the substrate 1 by performing well formation and threshold adjustment by introducing an impurity and a gate electrode 4a is formed. Then, an LDD layer 5 having a shallow junction is formed in the surface layer of the substrate 1 defined by the field oxide film 2 by implanting ions and side-wall insulating films 6 are formed on the side faces of the electrode 4a. In addition, a diffusion layer 7 is formed by implanting ions by using the electrode 4a and insulating films 6 as masks, and a first interlayer insulating film 8 is formed. Thereafter, the top face of the electrode 4a is exposed and cavities S are formed on the side faces of the electrode 4a by etching the insulating film 8 after flattening the surface of the film 8. Successively, a second interlayer insulating film 10 is formed on the whole surface. Since the cavities S are formed as air gaps 9 and the capacitance between the electrode 4 and diffusion layer 7 can be reduced, the operating speed of a logic circuit can be improved by shortening the delay time based on the capacitance.

Inventor: YAHASHI AKIRA
IPC: G06T1/00
Filed: 1995-11-17
Abstract: PROBLEM TO BE SOLVED: To provide a small projection apparatus in which a slit width can be adjusted and by which slit light with a small deformation can be radiated by a method wherein a laser beam which is radiated from a variator optical system used to adjust a beam diameter is spread to one direction and the slit light is generated. SOLUTION: In an optical system 40, a laser beam which is radiated by a semiconductor laser 41 is passed through a projection lens system 42, and it is changed into slit light U so as to be deflected by a galvanomirror 43. In the projection lens system 42, the laser beam is first made parallel by a collimating lens 241. Then, the diameter of the laser beam is adjusted by a variator lens 422. Lastly, the beam is expanded to a slit length direction M1 by an expander lens 423. Since a slit length is expanded before the beam is deflected by the galvanomirror 43, the deformation of the slit light can be reduced as compared with a case in which it ia expanded before the deflection.
