A personal communication apparatus is disclosed, which comprises a radio transmitter 64 and a radio receiver 66 for participating in communication, a microphone 60, a loudspeaker 61, a processor 90 as a controller for controlling call switching communication and packet switching communication, a ROM 100 and a RAM 101 for storing control programs and data, a call switching modem 80 for modulating signal in the speech frequency band, and a packet switching modem 82 for modulating signal in a frequency band exceeding the speech frequency band. The outputs of the microphone 60 and call switching modem 80 are bandwidth limited by a transmission signal processing circuit 72. Communication by the packet switching modem is carried out according to a communication program. The apparatus is capable of stand alone call switching communication and also of packet switching communication, as well as functioning as a radio telephone set.

A vortex flow blower used as an air source to be incorporated into general industrial machines. The vortex flow blower is characterized in that the shape of the blade in its impeller is three dimensionally formed such that at least the inner portion of the blade can be adapted to the three dimensional internal flow. According to the present invention, the aerodynamic performance can be significantly improved and the size of a vortex flow blower can be reduced. Furthermore, an impeller having three dimensionally shaped blades is manufactured by independently manufacturing the shroud and the blades and coupling them, so that the impeller of a complicated shape can be readily manufactured. Furthermore, since the blade can be made of a thin and light material, the secondary moment of inertia of the impeller can be reduced.

The present invention relates to a rotary drum unit in a helical scan type magnetic recording/reproducing device for use with a video tape recorder, digital audio tape recorded, or the like and is intended to permit the stable run of the tape with highly accurate formation of track patterns. In the helical scan type rotary head drum unit of the present invention, a dislocation of the tape upon the drums having no lead is detected by tape position sensors arranged along a guide line and the rotary head is moved in the axial direction of the drum by driving a dynamic tracking actuator in a manner to correct the deviation of the tape from the guide line.

An improvement of a reaction transmitting mechanism for a booster is disclosed. A forward end face of a tubular portion of a valve body which abuts against a reaction disc is provided with an uneven surface. This presents a resistance to an elastic deformation of the reaction disc when a brake booster is actuated. Accordingly, an enhanced hysteresis, which represents a difference in the output between when depressing and releasing a brake pedal, is provided without increasing the hardness of the reaction disc.

A vehicle disk player is disclosed in which a disk is inserted through a disk inserting opening, the disk is fixedly mounted on a turn table by a clamper arm when conveyed to a predetermined position in the player, the turn table is rotated for reproduction of data recorded in the disk, and reproducing means including the clamper arm and turn table are supported in a floating manner. The player is provided with a centering mechanism for positioning said disk at the middle of the disk inserting opening with centering pins. The centering pins are arranged out of the range of vibration of the disk which is fixedly mounted on said turn table supported in a floating manner.

An electric motor running system consists of a photovoltaic array, an inverter for inverting output voltage of the photovoltaic array to AC voltage and automatically controlled so that the frequency is changed in accordance with the output voltage of the photovoltaic array, maintaining the ratio of the voltage to the frequency at a constant value, an induction motor operated by application of the AC voltage from the inverter, and a frequency increasing circuit for increasing the output frequency of the inverter instantaneously so that the motor produces the torque larger than the load starting torque when the motor is started and further decreasing the increased output frequency of the inverter to the normal running frequency after the increased output frequency is maintained for a predetermined period of time. This construction allows the motor to be smoothly started even where a load connected to the motor is a positive displacement pump which has a large static friction torque.
