Inventor: TANAKA KUNITSUGU
IPC: H03F3/195
Filed: 1978-11-16
Abstract: PURPOSE: To obtain the hybrid integrated circuit that is a small size in extent that the divergence of high-frequency characteristics need not be modified, by providing with a power distributing circuit as one portion of the hybrid integrated circuit.  
     CONSTITUTION: A linear amplification circuit 12 is mounted to a central portion of an insulating substrate 11, and the input terminal 13, a power source terminal 14 and an earth terminal 15 are installed to the edges of the substrate 11. A power distributing circuit 16 is disposed being connected to the output of the amplification circuit 12. The circuit 16 mainly consists of resistance films 17, 18, and the output of the amplifier 12 is divided into two portions and extracted from output terminals 19, 20. According to this constitution, there is no necessity for connecting a power distributing circuit using resistance, a transformer, etc. to the outside of a hybrid integrated circuit as seen in conventional devices, this device can small be formed and mounting density is improved. Since a power distributor is manufactured by fast sticking resistance films on to the substrate 11, high-frequency loss and the unbalance of distributing output are little, and the correction of the divergence of characteristics becomes useless.

Filed: 1986-06-17
Abstract: PURPOSE:To expand the dynamic range for the amount of incident light by disposing a pair of switching arrays at both sides of one photo diode array, and independently driving the respective switch arrays with different shift registers. CONSTITUTION:A pair of switch arrays 12, 14 are disposed at both sides of a photo diode array 13, and they respectively select the outputs of a plurality of photo diodes. After time T1, a start pulse VS1 is inputted to a signal line 102 to cause a shift register 11 to be scanned for sequentially putting the segments 1, 2,...i,...n of the switch array 12 in the ON condition, thereby causing the signal charge stored in the photo diode array 13 to be outputted as a signal voltage Vout1 through a signal line 105. The signal charge to be outputted through the signal line 105 at this time has been stored in the photo diodes during the period corresponding to the input time difference T1 between the start pulse VS1 on the signal line 102 and a start pulse VS4 on a signal line 104. Thus, light can be detected without being limited by the read-out time and within a storing time shorter than it.

Title: Smoke discharge device
Inventor: ISHIHARA TAKAYUKI
IPC: F24F7/06
Filed: 1986-06-17
Abstract: PURPOSE:To rationally carry out the cooling of a motor and to prevent a detergent from invading into the inner part of the motor at the time of cleaning by providing a communication port for causing air which has flowed within the motor inner part to flow out at a predetermined speed on the outlet side of an air flowpath, and further arranging a cleaning nozzle toward a fan. CONSTITUTION:A detergent is ejected horizontally toward the rotation center of a fan from a cleaning nozzle 36. At this time, when a motor 22 is actuated to rotate a fan, the detergent scatters uniformly to a vane part 37, and further, a centrifugal force is applied thereto and scatters intensely over the side wall surface 38 of a fan casing 20 so that attached oil and fats can be washed away. Air surrounding the motor 22 flows in through a cooling port 32a of a motor housing 20 and passes through the inner part of the motor 22 to produce an air flow (arrow 39) reaching the outer periphery of the fan 24 via a cooling port 32b on the opposite side and a communication port 30. When the sectional area of the communication port 30 is turned down to a certain extent, the flow speed of air is increased, and the detergent dropping along the inner wall of the fan casing 20, atomized detergent and vapor does not come out from the communication port 30 to the side of the motor 22.

Title: Cheese cookie
Inventor: KAWAGUCHI SATOSHI
IPC: A23C19/09
Filed: 1989-06-01
Abstract: PURPOSE:To obtain tasty cheese cookie with milk fat cheese matched with the plain taste of rice cracker, by sandwiching sliced process cheese by a pair of rice crackers. CONSTITUTION:The objective cookie can be obtained by sandwiching sliced process cheese by a pair of rice crackers. The present cookie is pref. square with its size being 4-5cmX4-5cm. The reason is as follows: the established modern-style eating habit requires such cookie to be eaten at a mouthful rather than eating after cracking a larger-sized one. The above-mentioned size is enough to be eaten at a mouthful without the need for opening the mouth so widely. When baked in a relatively large-sized form, the cookie is cut after finished; in this case, a machine saw is pref. used for its cutting so that it is prevented from irregularly cracking and/or breaking.

Abstract: PURPOSE:To establish the optimum section of a runner communicating with a cavity while injection-molding, by fitting detachably a flow control plate, into which an inflow section regulating hole is formed, in the middle of the runner. CONSTITUTION:When movable side molds 2B, 3B are combined with stationary side molds 2A, 3a by moving a movable side bolster 1B, inflow section regulating holes 11, 11 of runners 7, 7 and flow control plates 12, 12 are combined with each other and formed into a circular state. When molten resin is pressed in through a sprue 5 with high pressure, the resin is caused to flow into cavities 8A, 8B, 9A, 9B for molding by passing through the inflow section regulating holes 11, 11 provided in the middle of the runners 7, 7. A circular sectional area obtained by combining the runners 7, 7 with each other is sufficiently larger than that obtained by combining the inflow section regulating holes 11, 11 and a flow of the resin flowing within the runners 7, 7 is regulated with the inflow section regulating holes 11, 11. A fill rate of a product molded in this manner is measured and when the fill rate in accordance with a design is not obtained, molding is performed again by exchanging with the flow control plate 12 whose sectional area is different from that of the inflow section regulating hole 11.

Abstract: PURPOSE:To reduce communication traffic for the notice of a present location and to secure regular information communication appropriately by informing the present location to a registration station by an exchange station when the history data of a mobile station is not related to its own station. CONSTITUTION:An individual mobile station 16 is registered on a specific ground station in advance. A section station (exchange station) 30, when detecting the mobile station 16 from the position history information of a specific mobile station 15 received for the first via a road station 10 under control, informs the present location to the registration station (area station) 32. The registration station 32 holds the data of the present location, and always updates the data in real time. The notice of the present location of the mobile station 16 to the registration station 32 is performed for the first by the section station 30 via the road station 10 in its area when noncoincidence between the position history information and the code of its own section is obtained. In such a way, the communication traffic for the notice of the present location can be reduced, and it is possible to prevent the communication traffic for regular information from being blocked.
