Title: Handset of telephone
Inventor: RIIDO SUKOTSUTO BURAUN
IPC: H04M1/03
Filed: 1989-11-20
Abstract: PURPOSE: To make the assembling of a handset easier at a low cost by deciding the outside diameter of an assembly of a flexible tubular gasket and a reception converter so that the assembly can be fitted in the first cylindrical cavity of a lower housing member and can be held in the cavity by the frictional force between the assembly and the internal surface of the cavity. CONSTITUTION: A handset has an upper housing member 800 and a lower housing member 100 and the first cavity 120 of the member 100 is completely opened at one end and has arranged small holes 160 for passing audible sounds at the other end. A parts assembly which is inserted into the cavity 120 is formed of a converter 300 and a flexible tubular gasket 200 and the gasket 200 has a flange which is expanded outward and protruded in the direction opposite to the inserting direction of the assembly into the cavity 120 on its outer periphery. The diameter of the cavity 120 is decided so that the cavity 120 can accommodate the inserted assembly and an excellent mechanical holding force can be obtained. The flange makes the insertion of the assembly into the cavity 120 easier and, at the same time, the removal of the assembly from the cavity 120 difficult. Therefore, the assembling of the handset can be made easily at a low cost.

Title: Studless tire
Inventor: FUKUMOTO TORU
IPC: C08L21/00
Filed: 1989-11-17
Abstract: PURPOSE:To improve gripping performance and durability even on the icy road surface and prevent damage to the road surface by using a tread rubber composition containing the specific ratio of water soluble polymeric powder of the specific average grain diameter to base material rubber. CONSTITUTION:In a studless tire used at the time of running on the icy road surface a tread rubber composition containing 3-25 weight part of water soluble polymeric powder of 20-600mum average grain diameters is used to 100 weight part of base material rubber. In this case, the above-mentioned powder remains as grains in the tread rubber composition and vulcanized as they are. When thus obtained vulcanized rubber is used as the tread of tire, powder crystal is exposed on the tire surface by abrasion so as to display spike effect. In addition, water cutting effect and gripping performance can be improved by gaps formed in association with falling of the powder.

Title: Soldering of integrated circuit
Inventor: TSUJIMOTO YOSHINOBU
IPC: B23K3/00
Filed: 1987-11-28
Abstract: PURPOSE:To substantially eliminate the problems of solder bridge and non- soldering by changing the soldering direction to the right-angled direction opposite to an integrated circuit at a position of solder pattern of an edge formed at one end of each side and by providing a space between a soldering iron and a solder pattern. CONSTITUTION:After moved to a position of a solder pattern 11a at one edge, a soldering iron is moved to a direction of an arrow B apart from a solder pattern 11a to remove a plenty of solder attached to the soldering iron. Since the solder pattern 11a of an edge is wider than the other solder pattern 11, it is provided with a larger amount of solder and the flow rate of solder due to heated solder iron is reduced for its larger area. Therefore, the amount of solder which is absorbed by a soldering iron when separated from a solder pattern 11a can be restrained, thus preventing a lead pin from remaining unsoldered.

Title: Lock-up clutch used for torque converter
Inventor: HIRAYANAGI TAKESHI
IPC: F16H45/02
Filed: 1995-10-26
Abstract: PROBLEM TO BE SOLVED: To prevent the lowering of strength of friction material and the like by forming oil grooves on the surface of an annular pressure reducing plate through which porous friction material is bonded to either the surface of a clutch piston of a lock-up clutch or the opposed face. SOLUTION: A pressure reducing plate 35 is bonded to the surface of a clutch piston 1 of a lock-up clutch for a torque converter, and friction material 40 is bonded to the surface of the pressure reducing plate 35. A plurality of oil grooves 42 are formed radially, for instance, at the pressure reducing plate 35. Accordingly, when the pressure of an oil chamber is heightened to press the piston 1 to a front cover, high pressure oil enters the friction material 40 from the oil chamber, but this oil enters the oil grooves 42 to escape so as to prevent such a state that the oil pressure becomes reaction to the pressing force of the clutch to impair torque transmission capacity. Since the oil grooves 42 are formed at the pressure reducing plate 35, the strength of the piston and the like is prevented from being impaired.

IPC: H04L12/40
Filed: 1988-11-30
Abstract: PURPOSE:To prevent the increase of load of a line, and to construct a network measuring system with high transmission efficiency and high throughput by informing and registering the abnormality of a node connected to a common line to/in other normal nodes, and suppressing the transmission of data to the abnormal node. CONSTITUTION:When each node 3 receives transmission data purporting that transmission is executed from an external device to another device connected to the common line 5 from an input/output control part 8, it checks whether there is an error (data length, data format, a destination node address) in this transmission data or not, and in the case of the presence of the error, it makes it a data corrective error, and does not send it to the common line, and returns an abnormality response to the external device. Next, it is confirmed whether the state of the node 3 of the destination of the transmission data is a down state or not according to a down node list, and if it is the down state, the response purporting that the data can not be transmitted because the destination is the down state is returned, and the transmission to the common line 5 is not executed. In the case where the node 3 of the destination is not the down state, a sending instruction is given to a network transmission control part 7, and the data is transmitted to the common line 5.

Title: Image pickup device
Inventor: KONDO KENICHI
IPC: H04N5/365
Filed: 1988-11-30
Abstract: PURPOSE:To obtain proper exposure for an object with any brightness at the time of strobe photographing by rapidly discharging the electric charge of a solid-state image pickup element immediately before the emission of a strobe. CONSTITUTION:After completely opening a mechanical shutter 2, the electric charge of the solid-state image pickup element 3 is rapidly discharged. Thereby, all signal charge accumulated before the discharge is discharged at that point and the signal charge of respective picture elements goes zero. The strobe 15 is emitted immediately after the discharging operation of the charge and the mechanical shutter 2 is rapidly closed after the end of strobe emission. When the shutter 2 is completely closed, the signal charge of the element 3 is read out. Consequently, a photoelectric conversion component due to exposure generated before the emission of the strobe which is the factor of an error in exposure is removed. In addition, the charge accumulation time of the element 3 is drastically shortened.

Filed: 1987-11-30
Abstract: PURPOSE:To improve a response characteristic of a motor by detecting an transient response state from the output of a speed error detection circuit and prohibiting an integral action of an integration circuit in the case of transient responsing. CONSTITUTION:A speed error detection circuit 3 outputs a periodic error signal of a period of a periodic signal which is the output of a rotary detector 2 and a period setting in advance. A state detection circuit 4 monitors the magnitude of the periodic error signal to decide whether it falls within a specific range or out of the range. An integration circuit 5 integrates the periodic error signal if the periodic error signal falls within a specific range, and an integral action is prohibited if the periodic error signal falls out of a specific range. An adder 6 adds the periodic error signal to the output of the integration circuit 5 to output to a driving circuit 7. According to the constitution, a response characteristic can be improved without changing any steady state characteristic.
