Patent JP-S62219965-A (JP)
Title: Manufacture of insulated-gate field-effect transistor
Inventor: UNO MASAAKI
IPC: H01L21/302
Filed: 1986-03-20
Abstract: PURPOSE:To obtain an IGFET in which the impurity concentration of a substrate is high in the drain side of a channel region only by a method wherein the drain side end of a polycrystalline Si gate electrode is so formed as to have an inclined plane and ions of B, which is impurity of P-type, the same conductivity type as that of the substrate, are implanted to make the impurity concentration higher in the drain side of the channel region. CONSTITUTION:One end of a polycrystalline Si gate 3 is inclined along the longitudinal direction of a channel. If B ions are implanted by using the Si layer 3 as a mask, the implanted ions are distributed with the same inclination as the Si layer 3 in the inclined side of a substrate. On the other hand, on the side of the vertical end of the Si gate 3, B ions are implanted in a region 4' which coincides with the edge of the gate electrode. Then large quantity of As ions are implanted under the condition that they are implanted into a shallower region than B ions. On the inclined side of the gate electrode, a region 5 which has the same sectional shape as the region of B but which is shallower than the region of B is converted into an N-type region and this region is used as a drain region. On the vertical end side, a region 5' is converted into an N-type region which is used as a source region. In this IGFET, the channel region on the drain side has a higher impurity concentration and smaller spread of a depletion layer and hence punch-through is hard to occur. On the other hand, the channel region on the source side has almost no P<+> type parts and very little impurity diffusion so that the characteristics are not degraded.

Title: Optical wave synthesizer and branching filter for optical communication
Inventor: SUEMATSU YASUHARU
IPC: G02B6/34
Filed: 1980-05-13
Abstract: PURPOSE:To obtain a high-resolution and stable optical wave synthesizer and branching filter which have low power loss and are easily integrated, by providing a Bragg reflector between two parallel optical waveguides and a coupled of 3dB couplers across the reflector. CONSTITUTION:Lithium niobate, other electrooptic crystal, or glass is used to provide two optical waveguides 21 and 22, a couple of 3dB couplers 23 and 24, and a grating 25 between the couplers as a Bragg reflector reflecting only an optical signal with prescribed wavelength onto a substrate 20 by masking technique. The couplers 23 and 24 are composed of layers 26 and 27 having high refractive indexes. When optical signal 21a differing in wavelength are inputted to the 21a, the optical signals propagate to a waveguide 22a via the coupler 13; and only an optical signal with the Bragg wavelength is reflected and outputted from the waveguide 22a, and the other optical signals are outputted from a waveguide 22b. An optical wave synthesizer operates reversely of said process. Thus, a stable optical wave synthesizer and branching filter which have high resolution and low power loss and are easily integrated can be obtained.

Filed: 1994-03-31
Abstract: PURPOSE:To automatically clean an original film in an exposure device without depending on manual work. CONSTITUTION:In this exposure device, an unexposed base plate supplied to a base plate feeding part is carried to an exposure part by a carrying means 6 and both sides of the base plate are simultaneously exposed through a pair of original films 1 and 2. A cleaning roller unit 40 is attached to the sucking plate 30 of the carrying means 6. When a pinion 44 is rotated by the driving of a motor which is not shown in figure, racks 46 and 47 meshing with the pinion 44 are moved, so that cleaning rollers 56 and 57 coupled with the racks 46 and 47 abut on the upper original film 1 and the lower original film 2, respectively, because the roller 56 ascends and the roller 57 descends. At such a time, both rollers press-contact with the films 1 and 2 by the action of spring members 52 and 53. By moving a slider 36 to the right in such a state, the rollers 56 and 57 rotate in a state where they press-contact with the films 1 and 2 and remove the dust of the films 1 and 2 by attaching the dust to the adhesive parts of their outer peripheries.

Abstract: PURPOSE:To cope with the arrival of flash flood easily by detecting the generation of the flash floor in the drainage course of a river, and by forecasting a time for arrival at a drain pump setting point, to operate the pump previously based on the time. CONSTITUTION:Drain collected by a drainage course 4 consisting of a main conduit line 6 and plurality of branch conduit lines 8 is led to a drain pump machine plate 2.

When the generation of flash flood is detected from the water level data of water level detectors (a), (b), (e), (f), then by the pump controller 14, forecasting arithmetic is performed on the arrival time of the flash flood with the use of a specified equation. Based on this result, the number of drain pumps P1, P2, P3 for being operated, and the operation- starting timing are determined, and previous standby operation against the flash flood is performed.

Title: String preparation containing liquid active substance and its production
Inventor: NINOMIYA YASUO
IPC: A01N25/18
Filed: 1983-04-12
Abstract: PURPOSE:The titled string preparation that has a gradually releasing coating film containing liquid drops of active sustances, which has a limited solubility in the polymer, in a number of isolated fine pores in a homogeneous polymer layer, thus being suitable for communication disturbance against insecticides by simple application. CONSTITUTION:The string preparation is produced by forming a coating film which has at least one surface layer containing a liquid active substance, preferably pheromone, in its isolated fine pores in a homogenous polymer in which the active substance has a limited solubility, on a string base. The string preparation is suitable as a device for releasing the active substance into the environment at a certain controlled rate for a long period of time and is easily applicable to effect continuous distribution in space, because it is a string. Therefore, when a pheromone is used as the active substance, it is very effective in communication disturbance against insect pests. Since fine pores are mutually, isolated, the string can be cut in an arbitrary length for use.
