摘要:
In a telephone system, which is arranged by a parent telephone unit and a plurality of child telephone units capable of radio-communicating with the parent telephone unit, the parent telephone unit includes a telephone number data storage table for storing a plurality of telephone number data indicative of a plurality of telephone numbers commonly usable by the plurality of child telephone units. The parent telephone unit retrieves the telephone number data storage table in response to a telephone number retrieve command issued from each of the plural child telephone units, and outputs a retrieve result to such a child telephone unit which has issued the telephone number retrieve command. Each of the plural child telephone units issues the telephone number retrieve command as a retrieve command issuing child telephone unit. Each of the plural child telephone units enters the retrieve result outputted from the parent telephone unit, and also outputs the entered retrieve result to a user of the retrieve command issuing child telephone unit.

A recording device includes a substrate having both an ink discharge portion with openings for discharging ink and a liquid chamber for holding the ink for supply to the openings, and a wiring portion transmits signals to electro-thermal converting elements. The wiring portion includes several electroconductive layers, an interlayer insulating layer made of first and second insulating layers, and a protective layer. Some of the layers have through holes, and the through holes are disposed within the liquid chamber. Different electroconductive layers are electrically connected via a through hole formed in the interlayer insulating layer. The through hole size varies so that the hole in a second electroconductive layer is larger than the through hole in a first electroconductive layer.

An LED display unit comprises a printed circuit board. A plurality of LEDs are packaged on the printed circuit board. Portions of the respective LEDs except for light emitting sections thereof are sealed by a resin. The LEDs having the portions thereof sealed by the resin are received in a case. A plurality of the cases are arranged on the attaching plate, to form a large-sized display panel. The case has a rear face thereof which is brought to a configuration in which spaces exist between the attaching plate and portions of the case except for a fixing portion thereof to the attaching plate and a connector for wiring.

An inner stripe with self-aligned saturable-absorber structure semiconductor laser comprises a semiconductor substrate of a first conductivity type; a semiconductor current-blocking layer (CBL) of a second conductivity type formed on the substrate and having a stepped channel composed of an optical-guiding channel and current-restricting channel which is grooved at the bottom of the optical-guiding channel through the CBL into the substrate; a semiconductor cladding layer of a first conductivity type formed over the CBL to bury the stepped channel; a semiconductor active layer of a first or second conductivity type formed on the cladding layer; and a semiconductor cladding layer of a second conductivity type formed on the active layer, whereby laser noises can be markedly suppressed through wide temperature fluctuations and through the optical feedback range.
摘要:
A lime material and a siliceous material containing 10 to 40% by weight of alumina are admixed with an alkali solution, and the mixture is subjected to hydrothermal reaction with saturated water vapor at 4 to 40 kg/cm.sup.2 to form tobermorite. The reaction mixture is filtered to separate the tobermorite therefrom. A lime material and a gypsum material are added to the resulting filtrate, and the mixture is reacted at room temperature to a temperature of 90.degree. C. to form ettringite. The alkali filtrate separated from the ettringite is reused for the production of tobermorite.

摘要:
When protective portions are independently provided for each energy generation element, a leakage current inspection between the protective portions and the energy generation elements cannot be performed at once. Therefore, there is a concern that the inspection in manufacturing a substrate for liquid ejection head requires time. Therefore, the substrate for liquid ejection head is manufactured by performing a leakage current inspection between a connecting portion that is electrically connected to plurality of protective portions and a terminal to which the plurality of energy generation elements are connected, and thereafter removing the connecting portion.

A memory access control device has a memory control unit and a software execution unit executing software. The memory control unit has: a data transmission unit configured to perform multicast transfer that reads a data from the memory and transmits the data to data transfer destinations through a network; a data reception unit configured to receive multicast transfer data from the network; and a reception data counter configured to indicate a number of multicast transfer data received by the data reception unit. The software execution unit instructs the memory control unit to perform a plurality of multicast transfers and then reads respective reception data counters of the data transfer destinations for each checkpoint in sequence of the software to determine completion of the plurality of multicast transfers.
