An information collecting system comprises an access terminal connectable to a data base through a network and a host computer, an IC memory card adapted for removable insertion into the access terminal, and a portable personal terminal. Requests for an item of information, from a customer, are inputted and recorded in the IC memory card using the personal terminal and the IC memory card is inserted into the access terminal. The request for information is transmitted through the access terminal to the data base and the requested information, transmitted from the data base, is stored in the IC memory card. Thereafter, the IC memory card, storing the information, is inserted into the personal terminal whereby the requested information is displayed on a display formed in the personal terminal.

In a function generating circuit which comprises a temperature sensor 1 for outputting an output current (Ilin) with a linear temperature characteristic or an output voltage (Vlin) with the linear temperature characteristic, a cubic function generating circuit 2 for receiving the output current (Ilin) or the output voltage (Vlin) of the temperature sensor 1 as an input and generating a cubic temperature characteristic voltage (Vcub), and a control data storing circuit 3 for recording control data to control the output characteristic of the cubic function generating circuit 2, an external control signal is applied to the temperature sensor 1 from an external control terminal 4 to cause the sensor to output variably the output current (Ilin) or the output voltage (Vlin) such that the temperature characteristic of the cubic function generating circuit 2 can be controlled at the ordinary temperature.

A temperature compensating crystal oscillation device includes a constant voltage circuit (12) for outputting a predetermined voltage independent of the ambient temperature, a temperature sensor circuit (13) for outputting a voltage in proportion to the ambient temperature, and a control circuit (14) for receiving the constant voltage output from the constant voltage circuit (12) and the voltage output in proportion to the temperature from the temperature sensor circuit (13) and for generating a control voltage (Vc) used for compensating a temperature characteristic of a quartz oscillator in the entire range of the ambient temperature through polygonal lines approximation of a negative cubic curve by using continuous lines. Furthermore, the crystal oscillation device includes a VCXO (15) whose oscillation frequency is controlled to be a predetermined value by the control voltage (Vc), and a ROM/RAM circuit (16) for storing temperature compensating parameters used for compensation of a temperature characteristic of the control voltage (Vc) for optimizing the oscillation frequency of the VCXO (15).

An apparatus for tightening connecting rod attachment members comprises a rotating mechanism for rotating and positioning a crankshaft about a center of its shaft section, angular deflecting mechanisms for deflecting nut runners about the center of the shaft section, axial displacement mechanisms for displacing the nut runners in an axial direction of the crankshaft, and inter-axis displacement mechanisms for making mutual approach or separation for a distance between the pair of nut runners and a distance between the pair of nut runners. The nut runners are operated to fasten a connecting rod to the crankshaft. Accordingly, one tightening apparatus can be used to tighten the connecting rod attachment members to the crankshaft even when the type of the crankshaft is changed. The tightening apparatus is applicable to a production line for carrying multiple types in a mixed manner.

An air breather plug assembly adapted for use in a transmission or trans-axle casing includes a cylindrical plug body detachably threaded into an upper portion of the casing and having an inner end portion which extends into an interior of the casing in a predetermined length, a cup-shaped baffle-plate fixedly coupled within the inner end portion of the plug body and being formed with a slot for permitting the flow of air passing therethrough, a cup-shaped seal member of elastic material fixedly coupled within an outer end portion of the plug body and spaced from the baffle-plate in a predetermined distance, the seal member being formed with a slit to be opened by an internal pressure applied thereto from the interior of the casing through the baffle-plate, and a cap fixedly coupled over the outer end portion of the plug body in such a manner as to allow the air flowing from the interior of the plug body to the exterior through the slit of the seal member.

With a variable capacitor including a load capacitor of an oscillation circuit having a feedback resistor 1, an inverter 2, and a crystal oscillator 3, and a static capacitance generated between a drain terminal and a gate terminal of MOS transistors 4 and 5, in which source and backgate terminals are shorted to each other, a serial connection of a DC cut capacitor 9, 10 and a variable capacitors (MOS transistor) 4 and 5 is formed between one end and the other end of the crystal oscillator 3. For example, a threshold voltage control signal of the MOS transistors 4 and 5 is input to the drain terminal through a high-frequency elimination resistor 11, 12, and is input to the source-backgate terminal through a high-frequency elimination resistor 7, 8. In addition, a signal obtained by overlapping a temperature characteristic compensation signal and a threshold voltage control signal of the MOS transistor 4, 5 is input to the gate terminal. Accordingly, it is possible to indiscriminately determine an output bias of a temperature compensation control circuit or an external voltage frequency control circuit.
