IPC: H01L29/808
Filed: 1982-06-30
Abstract: PURPOSE:To extremely reduce the change in the net quantity of impurities in a channel even when there is any change in the depth at the time of the diffusion of gate impurities, by providing a channel layer on the surface of an epitaxial layer on a substrate, and by providing J-FET in another epitaxial layer laid further on the above layer. CONSTITUTION:A p channel layer 4 is provided in an n epitaxial layer 8 on a p type Si substrate 1, and another n epitaxial layer 8a is further superposed thereon. A p<+> type drain 14, a source 13 and an n<+> gate 7 are formed in the layer 8a. According to this constitution, the density distribution of the channel 4 turns to be as shown by a curve 19 around the boundary 18 between the layers 8 and 8a. Even when a target curve 15 goes deep into a curve 16 at the time of the diffusion of gate impurities, the total quantity of the impurities is limited to an increase expressed by an area 17 and thus it is made to be very small. Therefore, gm and a pinch-off voltage proportional to the total quantity of the impurities of the channel can be controlled very effectively.

Title: Semiconductor laser device
Inventor: HAMADA TAKESHI
IPC: H01S5/00
Filed: 1984-06-04
Abstract: PURPOSE:To reduce optical absorption in the vicinity of the end surfaces of ridges, and to realize a high output by forming each layer containing an active layer onto a substrate to which two parallel ridges, width thereof is narrowed only in sections in the vicinity of the end surfaces, are formed. CONSTITUTION:The width of ridges 1a, 1b is formed in 5mum within 10mum from end surfaces and in 20mum in sections except the end surfaces. The height of the ridges 1a, 1b is shaped in 1.5mum, and the width of a groove between the ridges 1a, 1b is formed in 4mum. A first layer N type clad layer 2 is grown in 0.2mum in a flat section at the center, a second layer non-doped active layer 3 in approximately 0.05mum at the same position, a third layer P type clad layer 4 in approximately 1.5mum at the same position and a fourth layer N type cap layer 5 in thickness of approximately 0.5mum continuously on the substrate 1 through a liquid phase epitaxial method. Consequently, the film thickness dB of the active layer in the vicinity of the end surfaces of a laser chip is made thinner than that dA in the vicinity of the center, and the forbidden band width of the active layer is increased only near the end surfaces. Accordingly, since laser beams generated in the inside do not receive absorption near the end surfaces, the laser chip is difficult to be broken in the end surfaces, and extremely large optical outputs can be obtained.

Title: Label polarizing plate
Inventor: SUGIBUCHI SHIGEYOSHI
IPC: G02B5/30
Filed: 1981-07-22
Abstract: PURPOSE:To securely detect whether a polarizing plate to be stuck to an electrode cell is normal or not, by temporarily forming the polarizing plate on a carrier tape through a pressure sensitive adhesive, and then marking the polarizing plates for a photosensor along the half-cutting line of the label polarizing plate. CONSTITUTION:Polarizing plates 2 are stuck to a carrier tape 4 through a pressure sensitive adhesive 3 to obtain a long-sized lamination tape 1. The lamination tape 1 is fed to a half-cutting device 5 which consists of a roll cutter 7 having projecting knife-edges at prescribed intervals at the external circumference, and a knifeedge base 8 to half-cut the polarizing plates. In this case, the polarizing plates are marked, for a photosensor as shown by M, along half- cutting lines L to detect and sort the label polarizing plates 2' securely while discriminating the marks from air bubbles and flaws. A photoprinter, etc., is provided behind the half-cutting device 5 to draw lines with an about 0.5mm. width in a desired color, such as black, red and white, which is not sensed by the photosensor, thus performing marking M.

Filed: 1995-04-14
Abstract: PURPOSE: To provide an ultrasonic atomizer featured by efficiency and capacity of atomization, minute size and uniformity of particles, low power consumption, and low voltage operation. CONSTITUTION: When a complex body comprising a piezoelectric oscillator 1 in which a reed screen type electrode P and an electrode G are set in a piezoelectric ceramic 8 and an oscillating plate 2 is driven using a self-excited driving circuit, the piezoelectric oscillator 1 oscillates to transmit the oscillation to the oscillating plate 2.

Title: Paper feeder
Inventor: ODA HARUTA
IPC: B65H3/06
Filed: 1988-05-11
Abstract: PURPOSE:To enable a paper feed to be normally performed, even when paper is deformed, by providing position sensors, detecting a turning position of two feed rollers, and controlling the paper feed to be driven in accordance with a detecting result of the position sensors, in the case of a paper feeder for a character reader or the like. CONSTITUTION:When a paper form 12a in the uppermost part is curled, feed rollers 13, 14 are not set to the same turning position. Accordingly, a time difference is generated in an output of each position detection signal of position sensors 22, 23. That is, in a case such that the feed roller 14 is positioned in a curled part of the paper form 12a, the position sensor 23 outputs its position detection signal earlier by the time than the position detection signal of the position sensor 22. A control part 26, when it inputs each position detection signal of the position sensors 22, 23 not simultaneously, controls a paper feed to be driven changing its driving condition, for instance, such as by dropping a paper feed speed in accordance with the time difference between the position detection signals. Accordingly, the paper form 12a is fed in the driving condition of the paper feed in accordance with a deformation condition in that time.

Title: Sealing structure to rotating shaft
Inventor: GIYUNTAA PIICHIYU
IPC: F16J15/32
Filed: 1989-05-06
Abstract: PURPOSE: To provide a low-cost lip packing stretching in the radial direction in a hollow ring form by using at least one such lip packing as a spare packing and fitting it to a shaft or shaft bushing in tight contact thereto. CONSTITUTION: A packing 6 in a ring form is deformable elastically, and when no pressure medium is supplied to a cavity 7, its contacting edge 6' is positioned slightly apart from the oversurface of the bushing 2 owing to the elastic repulsion force. When pressure medium is supplied to the cavity 7, the edge 6' deforms so as to make pressure contact with the oversurface of the bushing 2, when the desired contacting pressure of the edge 6' is generated by adjusting properly the pressure of the medium. The packing 6 is positioned apart from the shaft 1 in normally operating condition, i.e., a filled packing 5.3 installed as facing the space S accommodating a lubricant is exerting its normal function.

IPC: H04Q3/64
Filed: 1977-09-21
Abstract: PURPOSE:To increase the reliability of the path selection relay by discharging the charge stored to the driving cable via the resistance and then eliminating the working action of the relay contact. CONSTITUTION:Channel driving unit 1 and channel unit 2 are connected each other via driving cable 5 and 6. And driving gate switch 3 and 4 plus driving source 11 are provided to unit 1, and unit 2 contains load 8 and path selection relay contact 7. Then resistance 12 is connected to cable 6, and the resistance value is increased up to such level that no effect is given to the driving current and that is small enough compared with the off-resistance of switch 4. As a result, the potential which is deleted through cable 6 when switch 3 and 4 plus contact 7 have no action becomes nearly identical to the earth, and thus floating capacity 10 is discharged, eliminating the working action of contact 7. Thus, the reliability can be enhanced for the relay.
