Patent JP-S61292953-A (JP)
Title: Semiconductor device
Inventor: WATANABE TAKASHI
IPC: H01L29/78
Filed: 1985-06-21
Abstract: PURPOSE:To simplify a circuit pattern, and to improve the degree of integration by forming P channel and N channel elements constituting a CMOS circuit by using a slender linear polysilicon layer. CONSTITUTION:An insulating film 21 consisting of silicon dioxide is shaped to the upper surface of a semiconductor substrate 20 composed of an silicon substrate, and several element Q1, Q2 and Q3 is formed by employing a slender linear polysilicon layer 22 shaped onto the insulating film 21. An impurity is doped selectively into the silicon layer 22, thus forming P-type regions 31a, 31b:32a, 32b and N-type regions 33a, 33b shaping respective source and drain region. Insulating layers 23 onto the upper surface of the polysilicon layer 22 and gates 24 consisting of polysilicon to which the impurity is doped are formed, thus constituting P channel MOSFETs Q1, Q2 and an N channel MOSFET Q3. Accordingly, there is no possibility of a latch-up because the elements are isolated from the semiconductor substrate 20 by several element insulating film 21, and areas required for element isolation are also reduced because the elements are isolated by high resistance sections (i) in the polysilicon layer 22.

Title: Two-cycle engine
Inventor: KATO KINICHI
IPC: F02B25/16
Filed: 1998-04-30
Abstract: PROBLEM TO BE SOLVED: To increase the rate of fuel consumption, while decreasing hydrocarbon in the exhaust gas greatly by circulating the scavenge gas of a proper concentration from the scavenging port to the combustion chamber of the cylinder head effectively without leaking out of unburnt gas from the exhaust port. SOLUTION: In the scavenging gas passage of this turning scavenging type two-cycle engine, the scavenge gas in a crankcase 7 is sent off via a narrow and horizontal scavenge gas release passage 11 over the crank case into the bottom of a scavenging passage of a cylinder 1 from the side of an exhaust port 4. Accordingly, the scavenge gas is separated into a thick gas comprising fuel particles having a large mass and a thin gas comprising fuel particles having a small mass before the gas is introduced to the scavenge port 5 located in the upper part. The scavenge gas thus introduced into the cylinder 1 is lifted in a loop from the inner wall opposite to an exhaust port 4 toward the cylinder head by a deflector 14 at the piston top. As a result, leaking out of unburnt gas from the exhaust port 4 is eliminated, and combustion efficiency in a combustion chamber 18 is improved.

IPC: G03G15/08
Filed: 1990-05-24
Abstract: PURPOSE:To simplify the service maintenance of the replenishing of toner by uniting plural color developing units of a developing device and a movement supporting body integrally and attaching/detaching to/from this image forming device main body in a batch. CONSTITUTION:In a rotary developing device 60, a rotary body 62 and four color developing units 64 are united integrally and the rotary body 62 and four color developing units 64 can be integrally attached/detached to/from the image forming device main body 50. In the rotary body 62, a rotary shaft 68 passing trough the center of the rotary body 62 is rotatively attached inside the device main body 50 by a bearing provided on both side pates of the image forming device main body 50, and the rotary body 62 integrated to the developing units 64 can be attached/detached together with the shaft 68. Therefore, when the toner in plural color developing units 64 of the developing device 60 runs out one after another, plural color developing units 64 are removed from the image forming device main body 50 together with the rotary body 62, and replacing to the rotary body 62 having new developing units 64 can be carried out. Thus, the service maintenance of the replenishing of the toner is simplified.

Title: Method and apparatus for mixing powders and particles
Inventor: MATSUNAGA MASABUMI
IPC: B01F33/40
Filed: 1987-05-29
Abstract: PURPOSE:To make it possible to carry out uniform dispersion easily and in a short time, by spraying powders or particles of different kinds from two air-spray nozzles in a semi-sealed hopper-shaped vessel and by making the forward ends of respective spray-patterns run against each other. CONSTITUTION:In a hopper-shaped vessel of semi-sealed type 1 powders or particles of different type a, B are sprayed from air-spray nozzles 2, 3 respectively, where spray-patterns therefor are shown by As, Bs. The forward ends of spray patterns As, Bs are forced to run against each other to cause thereby a turbulent flow. By this turbulent flow of fog-like particles, the powders or particles of different kinds are dispersed more homogeneously and uniformly. The mixed fog-like particles are drawn out of the vessel 1 to be collected as a mixture of different kinds of particles. As a result, powders or particles of different kinds can be uniformly dispersed and mixed homogeneously in a short time in a comparatively small vessel, leading to a great contribution to the improvement of quality and productivity.

Title: Method for measuring effective component in vapor phase inhibitor solution
Inventor: IRIE HIDEKI
IPC: C23F11/02
Filed: 1997-05-26
Abstract: PROBLEM TO BE SOLVED: To realize a low-cost, accurate and simple measuring method, by measuring an electric conductivity of a liquid sampled from a vapor phase inhibitor solution to be measured, and determining the concentration of an effective component of the vapor phase inhibitor solution to be measured on the basis of a preliminarily formed working curve of the concentration of the effective component of a vapor phase inhibitor solution and the electric conductivity. SOLUTION: The concentration of an effective component in an aqueous solution or alcohol solution of a nitrite such as sodium nitrite or an amine such as cyclohexil amine used as a vapor phase inhibitor solution is determined by an electric conductivity. The conductivity of the solution is measured simply by, for instance, dipping an electrode of a conductivity meter in the solution. When a constant function between the concentration and electric conductivity is induced from a measured value, a working curve is obtained. The conductivity of a liquid sampled from a vapor phase inhibitor solution to be measured is measured, so that the concentration of an effective component of the vapor phase inhibitor solution to be measured is obtained on the basis of the preliminarily prepared working curve.

Title: Laminated wiring board
Inventor: KAWAI TAKAHIRO
IPC: H01L35/28
Filed: 1987-06-01
Abstract: PURPOSE:To improve the cooling effect by constituting a power circuit layer and a grand circuit layer with a plurality of kinds of metals which can produce the Pertier effect. CONSTITUTION:A metal 1 and a metal 2 constituting a power circuit layer 21 and a grand circuit layer 22 are provided with the Pertier effect on their contact interfaces 3 and 4. Moreover, the power circuit layer and the grand circuit layer being laminated through the insulation layer 5 are composed of a metal 1 and a metal 2. Thus, when heat is produced with the Pertier effect at the contact interface 4 where current flows from the metal 1 to the metal 2 and the heat is absorbed due to the Pertier effect at the contact interface 3 where the current flows from the metal 2 to the metal 1, the contact interface 3 is near the part 8 which is the source of the heat and a contact interface 4 is arranged on a plate where the heat is easily radiated, thereby making it possible to transfer the heat more effectively than relying only on the temperature gradient, and allowing more effective cooling.
