Title: Connector and connector attaching structure
Inventor: TAKADA KENSAKU
IPC: H01R13/73
Filed: 1998-09-01
Abstract: PROBLEM TO BE SOLVED: To provide a connector with a simple structure that can easily be attached in a state of absorbing displacement. SOLUTION: A holder 5 formed in a prescribed position of a dashboard 1 is formed with a lock part 5f having a lock hole 5g. A connector 2 formed by integral molding is formed with a locked part 2c having a lock protrusion 2d to be inserted into the lock hole 5g, while the locked part 2c is connected to a housing 2g with thinly-formed connecting pieces 2e capable of bending. Accordingly, when the connector 2 is slid relatively to the holder 5, the lock protrusion 2d is inserted into the lock hole 5g so that the locked part 2c is fixed to the lock part 5f. In this state, even if positional displacement occurs between the holder 5 and the connector 2, the positional displacement can be absorbed without releasing the locking state because the connecting pieces 2e can be bent.

Title: Acoustic device for vehicle
Inventor: KASAI JUNICHI
IPC: H04R5/02
Filed: 1984-11-26
Abstract: PURPOSE:To reduce the degree of influences of leaked sounds upon the other passengers by attenuating a prescribed high sound band of the acoustic signal inputted to a high sound band attenuator through a selecting device and amplifying this attenuated acoustic signal and reproducing it with a speaker only for a passenger. CONSTITUTION:Individual passengers connect selectively selecting switches 21a-21d to fixed contacts P0-P3 in accordance with their desires. Then, acoustic signals of various selected programs are inputted from connected cassette decks 1 and 3 and tuners 2 and 4 to low-pass filters 22a-22d through output circuits 10-13. Low-pass filters 22a-22d attenuate high sound components of acoustic signals and input them to headphone amplifiers 23a-23d. Consequently, headphone amplifiers 23a-23d amplify acoustic signals whose high sound band of 1-2kHz is attenuated, and reproduced sounds where the high sound band is attenuated are radiated from headrest speakers 24a-24d toward ears of passengers.

Abstract: PURPOSE:To easily manufacture a hot rolled steel strip with thin scale on its surface. CONSTITUTION:This invention is related to a method for manufacturing the hot rolled steel strip with thin scale by which the hot rolled strip is cooled after completing finish rolling in hot rolling and descaling is executed by jetting high-pressure water at discharge pressure of 30-70MPa on the surface and back faces of the steel strip just before it is coiled under conditions that satisfies the undermentioned formula I. E>1.33X10<-4>T<2>-2.38X10<-1>T+1.06X10<2>...I. Where, E is collision energy (kJ/m<2>) which is defined by the undermentioned formula II, T is the temp. of steel strip (the surface temp. of steel strip, deg.C) before descaling. E=(PXQ)/(WXVX10<3>)...II. Where, E: collision energy (kJ/m<2>). P: discharge pressure of nozzle (Pa). Q: flow rate per one nozzle (m<3>/sec). W: jet width per one nozzle (m).

Title: Error processing system for buffer memory
Inventor: HIROSE MOTOYOSHI
IPC: G06F12/16
Filed: 1990-09-19
Abstract: PURPOSE:To execute the retry in the case a fixed fault exists in a specific way of a buffer memory by constituting the system so that LRU information never instructs an error generation way accessed immediately before as a replacement way. CONSTITUTION:When an access by a buffer memory (LBS) 5 which and data is read out, if an error is detected, retry of the access is executed. In this case, from the access sequence of the recent way shown by LRU information of an LRU memory 7, the the way whose latest access time point is the oldest is selected as a replacement way, and it always becomes different from the way in which an error is detected by the access executed immediately before. To the replacement way selected in this case, move-in of a data block which necessitates an access is executed, and thereafter, retry of the access is executed, and it hits this time. In the case the error generated previously is caused by a fixed fault of the way, the way is changed this time. In such a way, no data error is generated and it is possible to make retry successful.

Title: Fuel injection controller
Inventor: YAMAGUCHI HIROSHI
IPC: F02D41/34
Filed: 1984-11-26
Abstract: PURPOSE:To prevent the thickening of air-fuel ratio by judging if asynchronous injection is to be carried-out or not and carrying-out asynchronous injection by selecting the group of cylinders which carries-out asynchronous injection when the number of engine revolution reduces in comparison with the number of recovery revolution during fuel cut. CONSTITUTION:During engine operation, the fuel injection amount is calculated in an injection-amount calculating means (c) on the basis of the output of an operation-state detecting means (b). An injection-signal outputting means (d) outputs an injection signal in synchronization with a prescribed crank angle for each group, into a fuel injection valve (a) which is installed for each cylinder and divided into a plurality of groups. In a prescribed deceleration operation state, output of the injection signal is suspended by a fuel cut means (e). When the revolution speed of the engine at this time reduces below a prescribed number of recovery revolution, an asynchronous injection control means (g) judges that synchronous injection is to be carried-out or not on the basis of the engine operation state, and when the judgment is 'YES', the cylinder group in which asynchronous injection is carried-out is selected, and asynchronous injection is carried-out.

Title: Discharge lamp lightening device
Inventor: KAMIYA TAKAYUKI
IPC: H05B41/24
Filed: 1990-09-18
Abstract: PURPOSE:To stably keep the discharge state in a lamp without generating an idle period of a lamp current, by connecting condensers with a discharge lamp in parallel when the discharge lamp is started, and by disconnecting said condensers from the discharge lamp after the discharge lamp has been started. CONSTITUTION:Condensers 5, 8 are connected to a discharge lamp in parallel after the discharge lamp is started, and condensers 5, 8 are disconnected from the discharge lamp after the discharge lamp has been started. In this case, the current itself flowing in a choke coil 6 is the lamp current as there is no parallel circuit across the discharge lamp 7 after the discharge lamp has been started. Thus, when the direction of the current flowing in the choke coil changes, half the output voltage of a direct current power supply 1 is applied across the discharge lamp 7. Consequently, in the case of a lamp with high striking voltage such as an end-of-life lamp, the discharge state of the lamp is stable in such a way that neither flicker nor lights-out is likely to occur.

Title: Device for caulking rivet
Inventor: KANAZAWA KUNIYOSHI
IPC: F15B11/028
Filed: 1996-09-20
Abstract: PROBLEM TO BE SOLVED: To enable the amplification of caulking pressure by providing a double pressure means with a piston having smaller flow-out side pressure receiving area than a flow-in side pressure receiving area in a hydraulic cylinder having the flow-in hole from a pressurizing means and the flow-out hole to a pressing means. SOLUTION: Since the urging force of a coil spring 4 is larger than a hydraulic pressure in a little interval which starts the oil supplying into the hydraulic cylinder 6 from the flow inlet 2c through an oil supplying pump, a ball is pushed down and the hydraulic oil is transferred to the pushing device side. When the hydraulic pressure exceeds the urging force of the coil spring 4, the piston 3 is worked and the ball 5 closes a through-hole 14a with the force of the coil spring 6 to shut off the oil flow. Since the pressure receiving area at the flow-out hole 2d side is smaller than the pressure receiving area at the flow-in hole 2c side, the hydraulic pressure with the piston 3 is doubled with the double pressure device 1.  By this constitution, the pushing rod for caulking is pushed down at the high pressure and low speed without rising the capacity of the oil supplying pump, and the rivet can surely be staked. In the case of being an unnecessary place in the high pressure, the piston 3 is driven at the low pressure and high speed.
