摘要:
A facsimile system with the body thereof usable as a subunit of a cordless telephone is disclosed. A parent unit is connected to the telephone line. A facsimile subunit is connected by radio to the parent unit. A telephone subunit is also connected by radio to the parent unit. A circuit included in the parent unit detects a signal indicating that the other party is in facsimile transmission mode. When a call signal is detected from the telephone line, the parent unit connects the line. When a CNG signal is detected, on the other hand, the parent unit connects the facsimile subunit by radio. In the case where a CNG signal is not detected, the parent unit starts the ring-up tone on the telephone subunit. An AGC circuit and a voice mute circuit are included in the parent unit.
摘要:
A speech message recording and reproducing method and apparatus wherein a speech message associated with a facsimile transmission is stored in a communication apparatus having an automatic answering telephone apparatus associated with a facsimile apparatus. Information of the speech apparatus including at least a storage address thereof is converted to an optical pattern for printing on a recording paper. The printed optical pattern is optically detected, interpreted and transmitted by radio communication to the communication apparatus and the speech message stored at the storage address is reproduced. The optical pattern is read by a reader forming part of a portable telephone unit.

In case of inserting an IC having multiple pins into an IC socket so as to be brought into contact with the IC socket, a contact pressure application unit is integrated with the IC socket, whereby the IC is inserted into and brought into contact with the IC socket without bending a lead of the IC. An IC contact mechanism comprises a contact pressure application unit having a through hole at the center thereof, the contact pressure application unit also having a mold guide portion so as to contact an outer periphery of a package of an IC and a lead presser portion for pressing a lead of the IC; and a suction block having a suction pad at the tip end thereof and movable vertically in the through hole of the contact pressure application unit characterized in that the IC is inserted into a contact socket so as to be brought into contact with the contact socket while the suction pad sucks the IC.
摘要:
A process for producing 2,6-naphthalene dicarboxylic acid which comprises oxidizing a 2-alkyl-6-acyl naphthalene with molecular oxygen-containing gas in the presence of a catalyst containing cobalt, manganese, bromine and at least one metal selected from the group consisting of iron, copper and mixtures thereof in an acetic acid solvent is disclosed.
摘要:
A process for producing polyolefins and particularly polyethylene which are high in molecular weight or which are wide in molecular weight distribution and thus suitable for extrusion or blow molding purposes, the process comprising polymerizing olefins such as ethylene by the use of a catalytic system which is comprised of a solid catalytic component obtained by mixing or interacting oxygen-containing organometal compounds or halides of (a) vanadium and (b) hafnium or a solid catalytic component obtained by mixing or interacting oxygen-containing organometal compounds or halides of (A) vanadium, (B) hafnium and (C) titanium, and (D) an organoaluminum compound, and of an organoaluminum compound.

In a suspension system for an automotive vehicle which comprises a longitudinal shaft fixedly mounted on the vehicle body structure along the fore-and-aft axis, a control arm of the so-called "A" type swingably supported at one end thereof from the shaft by means of a pair of front and rear rubber bushes, and a pair of retainer plates fixed to front and rear ends of the shaft and arranged to receive a load acting on the control arm in the forward or rearward direction through a portion of the respective rubber bushes for restricting forward or rearward displacement of the control arm, a stopper member is secured to the rear portion of the control arm and straddling the rear end of the shaft with a predetermined clearance, the stopper member being brought into engagement with the rear end of the shaft when the load acting on the control arm is larger than a predetermined value.
摘要:
Terephthalic acid is produced by oxidizing, in a liquid phase, p-tolualdehyde with a gas containing molecular oxygen, for example, air, in the presence of a catalyst consisting each of (1) a manganese compound, (2) a cobalt compound, (3) a bromine compound, and (4) at least one compound selected from the group consisting of chromium compounds, iron compounds, nickel compounds and compounds of metallic elements belonging to the lanthanide series, using a lower aliphatic monocarboxylic acid as a solvent.
摘要:
A process for the preparation of polyolefins, polymerizing olefins with use of a solid catalyst separated from a reaction mixture which is obtained by reducing a halogen-containing compound of vanadium with an organic aluminum compound in the presence of an ether and an organic aluminum compound.
摘要:
A storage apparatus of an embodiment of the invention including one or more storage drives for providing real storage resources and a controller for controlling the one or more storage drives and accesses from a host computer. The controller initializes real storage resources and manages the initialized real storage resources. The controller receives an instruction for allocating an initialized real storage resource to a first virtual storage resource accessed by the host computer. In response to the instruction, the controller allocates a first initialized real storage resource which has been initialized in advance prior to the instruction to the first virtual storage resource.
摘要:
In a knock control device of an internal combustion engine equipped with a control unit which updates a background level based on an output signal from a knock sensor and detects the generation of a knock by comparing a variation of the background level with a knock determination value, a determination as to whether the knock is generated is performed by ((variation of first filter value of peak hold value)>((1−filter coefficient)/(1+filter coefficient)×(predetermined value larger than maximum value of variation of peak hold value in case where knock is not generated))).
