摘要:
A process for producing a polymer having sulfonic acid groups is provided which comprises treating a polymer having sulfonate salt groups with a ion-exchange resin to change the sulfonate salt groups into sulfonate acid groups with porous-type strongly acidic cation exchange resin. A process for producing a tertiary alcohol is also provided which comprises hydration of olefin by use of the aforementioned polymer as the catalyst. By the process, a tertiary alcohol is produced by hydration of olefin with high selectivity at low cost.

A package tester includes an inlet station for arranging a test board in which package sockets mounting packages are disposed in one or plural lines for performing package test by flowing an electric current through the package and transmitting signals to the package, the package being composed of parts including electric parts or electronic parts and being sequentially formed on a package tape, an inlet pusher for pushing the test board mounting the packages by a width of the test board in a feeding direction of the test board from the inlet station to the package socket, a conveyor for receiving the test board sequentially pushed out of the inlet station by the inlet pusher and conveying the received test board to a testing area, a contact device opposed to the conveyor and capable of being electrically connected to the test board arranged on the conveyor, an outlet station receiving the test board sequentially pushed out of the conveyor by sequentially pushing-out of the test board by means of the inlet pusher, and a reaction urging device for allowing the test board to be pushed out while supporting the test board pushed out to the outlet station with force weaker than pushing out force in the inlet pusher.
摘要:
A method of timing an event in an internal combustion engine embodying sensors that sense a reference output shaft angle position and a series of incremental output shaft angle positions each sensed by a respective sensor. The timing of the event is chosen to follow an output signal of the incremental sensor and the time of delay between that and the timing of the event is adjusted by measuring the offset between the reference position sensor and the angular position sensor.
摘要:
A temperature compensated ignition control device wherein the temperature sensor is mounted on the circuit for the spark advance and the complete assembly is mounted in proximity to a portion of the engine for sensing its temperature and advancing the spark during cold starting.
摘要:
A vessel speed indicating device including a semiconductor pressure detector that detects dynamic pressure and outputs a signal indicative of this pressure. A speed indicator and calculator is incorporated which senses when the speed is below a speed at which high accuracy can be expected and outputs a warning signal in the event of that condition. Alternatively, when the device is operating in a range where the speed signal is accurate, actual speed is indicated.
摘要:
An automatic analyzer is capable of controlling the gap between the tip of the sample nozzle and the bottom surface of the reaction container and restricting the sample attached to the tip of the sample nozzle. A movement distance of an arm is calculated and stored while the tip of the sample nozzle contacts a coordinate measurement stand until a stop position detector detects a stop position detection plate. The sample nozzle is moved toward the bottom surface of the reaction container and is stopped at the time when the stop position detector detects the stop position detection plate. The arm is moved upwardly for the movement distance stored in memory from this position. The sample nozzle can be stopped such that the tip of the sample nozzle is contacted to the bottom surface of the reaction container and the bend (warp) of the sample nozzle is restricted.

摘要:
According to one embodiment, a television apparatus includes a main body, a housing, an exothermic component, and a heat transfer mechanism. The main body has a display screen, and is used in a first orientation where one side of the display screen is positioned on the upper side and in a second orientation where another side is positioned on the upper side. The housing at least partially constitutes the outline of the main body. The exothermic component is housed in the housing. The heat transfer mechanism includes a heat receiving portion that receives heat from the exothermic component, a heat releasing portion that releases heat, and a heat transferring portion that houses a medium to transfer heat from the heat receiving portion to the heat releasing portion. In both the first orientation and the second orientation, the heat receiving portion is located lower than the heat releasing portion.

An electronic component comprises an element body, an external electrode, and an insulating resin coating layer. The element body has a pair of end faces opposed to each other, a pair of principal faces extending so as to connect the pair of end faces and opposed to each other, and a pair of side faces extending so as to connect the pair of principal faces and opposed to each other. The external electrode is formed so as to cover at least a partial region of the principal face and/or a partial region of the side face and has a plating layer comprised of Sn or an Sn alloy. The insulating resin coating layer covers at least the portion of the external electrode formed so as to cover the side face.
摘要:
A node device connected to other node devices has a particular obtaining unit that obtains search information including, a first determination unit that applies a predetermined rule to determine whether the search information obtained by the particular obtaining unit is required to be stored in the node device. The node device has a first storage unit that stores search information when required, and a second determination unit that determines whether the search information obtained by the particular obtaining unit is newly published in the network. A second storage unit stores the search information when the second determination unit determines that the storage information is newly published. A search unit searches the content data, based on the search information stored in at least one of the first storage unit and the second storage unit.
