Title: Discharging device for sediment
Inventor: KOJIMA MASAYUKI
IPC: B01D21/18
Filed: 1980-12-19
Abstract: PURPOSE: To prevent excessive external forces from being exerted on a chain travelling on the bottom surface of a sedimentation basin and facilitate the operation of the device by providing a mechanism for lifting up the chain and drawing it out from sediment when an excessive external force is exerted on the chain.  
     CONSTITUTION: Above the sedimentation basin 1, a truck 5 with a sprocket wheel 17 is provided to be freely horizontally movable in parallel to the plane on which the chain 21 is stretched. One end of a link bar 7 is pivotably supported by the truck 5, and the free end of the bar 7 is fitted with another sprocket 15. Another link bar 10 has its one end pivotably supported at an approximately middle part of the link bar 7, and the other end of the bar 10 is pivotably supported by a shaft 11 provided in an upper space. When an excessive external force is applied to the chain 21, a compressive force is exerted in the axial direction of the link bar 7 and a horizontal component force is generated in the truck 5 at a shaft 6. When the component force is larger than the driving force of a torque motor 24, the truck 5 is retracted downstream and the link bar 7 is swung upwards, causing a shaft 8 to move vertically upwards. Accoringly, the sprocket 15 is moved up above the sediment 1.

Title: Portable musical instrument
Inventor: ASAHI YASUHIKO
IPC: G10H1/00
Filed: 1988-07-20
Abstract: PURPOSE:To enable the reproduction of a heavy low-frequency sound even when the musical instrument is reduced in size by providing a driving means which drives a vibrator so as to cancel operation from a resonator side to a vibrating body. CONSTITUTION:When a sound generating device 2 is put in operation, a sound generating circuit 7 converts the vibration of the device 2 into an electric signal. A vibrator driving circuit 8 drives the vibrator 4 according to the electric signal. When a driving signal is supplied from the circuit 8 to the vibrator 4, a diaphragm 3 is driven forward and backward reciprocally. Here, the rear surface side of the diaphragm 3 forms a resonance driving part for driving the Helmholtz's resonator consisting of a sealed box 5 and a duct 6. Atmospheric reaction to the operation of the diaphragm is applied to the rear surface side of the diaphragm 3 from the air in the sealed box 5, but the circuit 8 drives the diaphragm 4 so as to cancel the atmospheric reaction. Consequently, the frequency characteristics of a direct radiant sound is not affected by the capacity of the sealed box 5. Therefore, even if the sealed box 5 is reduced in size, reproduction up to a low frequency sound is possible and the musical instrument is reducible in size.

Title: Structure for rivet fastening
Inventor: YOSHIKAWA RYOSUKE
IPC: F16B19/10
Filed: 1997-06-20
Abstract: PROBLEM TO BE SOLVED: To remarkably reduce the dislocating quantity between members to be fastened to each other when joint of members, structures, and the like are performed by rivets, by forming the diameter of a hole for rivet fastening of a fastened member on the caulked side larger than a hole for rivet fastening of a fastened member on the flange side. SOLUTION: As for hole diameters of a flange side fastened member 2 and a caulked side fastened member constituting a structure for rivet fastening, the hole diameter on the caulked side is formed into a larger diameter. A caulked side mandrel 12 fixes a flange 11 so as to press it to the flange side fastened member 2 and pulls a mandrel 9 in the right direction so as to withdraw, hence a blind rivet 1 is largely swelled in diameter so as to form a swelled diameter part 13, while moving to the flange side, and when the mandrel 9 is defeated by pulling force, the mandrel 9 is fractured so as to complete fastening. At this time, the swelled diameter wall 14 of the swelled diameter part 13 formed at pulling bites in the gap of the caulked side fastened member 3 so as to form a nearly blockaded state.

Title: System for updating storage of areal information in vehicle monitoring system
Inventor: HIRAO TAKASHI
IPC: G08G1/123
Filed: 1983-09-29
Abstract: PURPOSE:To improve the service to users and increase the income by treating the fact that a car stays in the same area for a long time under a vacant condition as area indistinct information and giving no allocating command to the car to prevent abnormal concentration of vacant cars in a specific area. CONSTITUTION:Areal information data received by a receiving section 10 for sign post are supplied to a data detecting section 18 through an input terminal 17 and detection of the data is performed at the section 18. Whenever new area information data are detected, data stored in memory sections 19-21 are shifted one step by one step and the latest areal information is stored in the memory section 19. When input of areal information data of a car is not detected even when a control time has passed, a timer 22 treats all the content of the memories 19-21 on the car as area indistinct information and makes a car allocating center give no allocation to the car. Therefore, each car necessarily runs different areas for more than a fixed time and equalizes its car running distribution. As a result, abnormal concentration of vacant cars in a specific area can be prevented and services to users outside a specific area can be improved and, at the same time, income can be increased.

IPC: H01L21/768
Filed: 1988-07-19
Abstract: PURPOSE:To increase the contact area of a wiring to a conductor layer by the area of the side surface of a recess part and to decrease the contact resistance between the conductor layer and the wiring by providing the recess part with respect to a contact hole in the conductor layer in a self-aligning pattern, and bringing the wiring into contact with the conductor layer at the bottom surface and the side surface of the recess part. CONSTITUTION:A recess part 5a is provided with respect to a contact hole C in a TiSi2 film 5 in a self-aligning pattern. A wiring 7 is brought into contact with the TiSi2 film 5 at the bottom surface and the side surface of the recess part 5a. The contact area of the wiring 7 to the TiSi2 film 5 is increased by the area of the side surface of the recess part 5a in comparison with a conventional device. The contact resistance of the wiring 7 with the TiSi2 film 5 can be decreased by the amount corresponding to the increase. Even if the contact hole C is miniaturized with the implementation of high integrating density in the semiconductor integrated circuit device, the increase in contact resistance of the wiring 7 can be suppressed. Therefore, the decrease in operating speed of a transistor can be prevented. Thus, the high integration density and the high performance of the semiconductor integrated circuit device can be implemented.

Title: Light reception circuit
Inventor: OTSUKA TOMOYUKI
IPC: H04B10/293
Filed: 1987-07-20
Abstract: PURPOSE:To make a load resistance controllable for a photodetector, by composing the photodetector and FET connected in series with the photodetector and next by varying a bias between a gate and a source in the FET. CONSTITUTION:A photodetector PD is used to convert a light input into an electrical signal. An FETQ1 is connected in series with the photodetector PD, and it functions as a load resistance for the photodetector PD. The load resistance for the photodetector PD can be controlled by varying a bias between a gate and a source of the FET. Since an equivalent resistance of an FETQ2 is thus used as the load for the photodetector PD to make a channel conductance of the FETQ2 variable by the use of the external bias, the load resistance for the photodetector PD can be arbitrarily controlled. The equivalent resistance value Rds of the FETQ1 serving as the load resistance for the one photodetector PD is thus changed by varying a voltage Vgg applied to the gate of the FETQ1. In the case of a low-speed signal, the Vgg is made high to enlarge the resistance value Rds so that reception sensitivity is upgraded and besides its band width is limited. In the case of a high-speed signal, the Vgg is made small to lower the resistance value Rds that the reception sensitivity is downgraded to make the bandwidth large.
