Title: Coupling device between piston and connecting rod in engine
Inventor: YAMADA SETSUO
IPC: F16J1/16
Filed: 1998-03-06
Abstract: PROBLEM TO BE SOLVED: To prevent the service life of a piston from being lowered due to corruption of a piston pin hole in the piston caused by elastic bending deformation of a piston pin due to expansion pressure of combustion gas. SOLUTION: A piston pin 7 is fitted in a pair of piston pin holes 3, 3 formed in a piston 1 and in a pin fitting hole 6 formed in a connecting rod 4, bridging therebetween, and outer peripheral surface parts 7a of the outer peripheral surface of the piston pin 7, which are inserted in the piston pin hole 3, are tapered toward connecting rod 4 so as to define gaps 9 having a width which gradually increase from the end part side of the piston pin 7 to the connection rod 4, for allowing elastic deformation of the pin. Further, in such a case that the piston 1 is exerted with an expansion pressure of combustion gas, the piston pin 7 is deformed, being elastically bent, so that the gap 9 for allowing elastic deformation of the pin becomes narrower, and accordingly, the piston pin holes 3 and the piston pin 7 are made into contact with each other over predetermined distances.

Title: Adjustment of river water flow
Inventor: OGATA KORETADA
IPC: E02B7/20
Filed: 1981-04-09
Abstract: PURPOSE:To prevent the inflow of the sea water into a river at high tide as well as unnecessary outflow of river water at ebb tide by using a system in which a height adjustable dam is provided from the river bed to the sloped  shoulder of the river in the tide sensible area of a river and the height of the  dam is adjusted to the same level as the sea water. CONSTITUTION:In the tide sensible area of a river, a or plural height-adjstable mobile dams are provided from the river beds 1-2 to the sloped shoulders 5-4 of the river. The height of the dams is always adjusted to the same level as the sea water at high tide. By this, the inflow of the sea water into the river is prevented at high tide, the outflow of the sea water from the dams is prevented  when the level of the river water is below the sea water levels 3-9, and the  river water above the sea water level is flowd into the sea. Thus, unnecessary  outflow of the river water into the sea can be avoided.

Title: Achromatic toner and manufacture thereof
Inventor: MUROFUSHI KATSUMI
IPC: G03G9/087
Filed: 1995-03-14
Abstract: PURPOSE: To provide an achromatic toner hardly causing any change in a tone of the achromatic toner and a tone of an image formed by using the achromatic toner by comprising two or more kinds of domains containing different kinds of pigments. CONSTITUTION: In an achromatic toner consisting of a matrix, in which a binding resin A is contained as a principal constituent, and domains, in each of which a visible rays - near infrared rays absorbing pigment, an achromatic agent, and a resin B are contained as principle constituents, the domains are constructed of at least two kinds of domains containing different kinds of pigments respectively. In this case, the different kinds of pigments are contained in the different domains individually, so that these different kinds of pigments are not mixed directly with each other, and as a result, a tone of the achromatic toner and a tone of an image can be prevented from the change due to interaction between the different kinds of pigments.  On the other hand, fading retention rates and/or achromatic rates in the domains are regulated to be equal to each other, so that achromatization of an image can be unifomly carried out in a short time.

Title: Information recording system
Inventor: SHIBATA TAKEHIKO
IPC: G11B20/18
Filed: 1986-03-12
Abstract: PURPOSE:To preliminarily prevent the increasing of a recording error sector beforehand by re-recording a substitute sector only when a recording data is discriminated as after the result of checking of a recording data and prescribed conditions are satisfied. CONSTITUTION:When reading is confirmed after the recording of information and an error is detected, the information is re-recorded to the prescribed area of the recording media only when prescribed conditions are satisfied. For example, when the action of respective blocks 6-8 at the time of recording a recording system is normal, respective digital conditions 12-14 inputted to an AND gate 10 is all '1', the input of the AND gate 10 comes to be all '1' by an error detecting output '0' of a control part 3, and consequently an output '1' of the AND gate 10 is outputted. When the '1' is inputted to the control part 3, an error processing when abnormality is absent at the recording system is obtained, and therefore, the error processing by a substitute sector can be started. On the other hand, when the block of either of recording systems 4 is not abnormal as the result of the monitoring at the time of recording, the abnormality detecting output of the abnormal block comes to be '0', therefore, the output of the AND gate 10 comes to be '0'.

Abstract: PURPOSE:To check the abnormality of an apparatus at any time, by introducing dummy input into an input circuit at a constant cycle while comparing the state change from an event memory circuit and the time thereof by reading both of them. CONSTITUTION:A signal for generating state change is outputted at every constant time (tsec) from a timer circuit 7 and dummy input is introduced into an input circuit 2 from an output circuit 8 by said signal. That is, when state change is generated at every tsec from a certain time T0, the state change data is stored in an event memory circuit 4 along with the generation time thereof. Herein, the content of the event memory circuit 4 is read by a reading circuit 9 in which the state change generating time and data are, in turn, collected and the change generating time and the state thereof are compared by a coicidence and non-coincidence detecting circuit 10. The comparison with time data containing data fro showing the address position of a dummy input circuit is taken and, when the difference is tsec and the data is coincided with the output of the timer circuit, the generation of abnormality is found and an abnormality contact output circuit 11 is operated.

Title: Method for connecting optical connector and device for connecting this connector
Inventor: SASAKI KOJI
IPC: G02B6/36
Filed: 1990-03-06
Abstract: PURPOSE:To suppress the fluctuation and increase in light loss at the time of butting optical connectors against each other and connecting the end faces thereof by constituting the above device in such a manner that the energizing force of a compressing spring to hold the connecting end faces in a butted state after connection of both ferrules is weaker than the gripping force in a radial direction by a split sleeve. CONSTITUTION:The energizing force of the compressing spring 18 which holds the connecting end faces in the butted state after the connection of the movable ferrule 13 and the stationary ferrule 11 is so set as to be weaker than the gripping force in a radial direction by the split sleeve 12. A butting stage 14 is, therefore, advanced by the energizing force of the compressing spring 18 smaller than the gripping force of the split sleeve 12 and the connecting ends of the two ferrules 11, 13 are held in the adequate butted state if the engagement of the butting stage 14 and a sliding member 16 is released after the stationary ferrule 11 and the movable ferrule 13 are butted and connected. The deviation in the connecting end faces is obviated in this way and the fluctuation and increase in the light loss are suppressed.

Title: Alarm device
Inventor: HIRAYAMA SHIGERU
IPC: B60W30/00
Filed: 1996-03-13
Abstract: PROBLEM TO BE SOLVED: To automatically continue an alarm condition when a stop lamp switch is abnormal by detecting the continuous ON state of the stop lamp switch for a specified time and prohibiting releasing of the alarm condition by its detection output. SOLUTION: A control circuit 10 is provided in a control means 5 and this control circuit 10 takes in the output of a stop lamp switch 1 and determines whether the switch is ON or not. If the switch is ON, a counter is set and if the switch is OFF, the counter is reset. Then, when an alarm is in an generated state, if a counted value exceeds a preset value within a range of 8 to 20 sec., a failure is determined because it is too long for a braking operation and releasing of the alarm condition is prohibited. Thus, the alarm condition is maintained and safety is improved.
