Title: Hydraulic vibration actuator
Inventor: SHINOHARA MASATOSHI
IPC: F15B15/14
Filed: 1979-03-13
Abstract: PURPOSE: To enable a vibration actuator to cause vibration of high frequency and small amplitude with high efficiency as well as vibration of large amplitude, by moving one end wall of a cylinder in its axial direction.  
     CONSTITUTION: A piston rod 12 extending through an end wall 3 and another piston rod 14 extending through another end wall 2 are integrally provided on the piston 6 of a hydraulic vibration actuator. The end wall 2 can be displaced relatively to a cylinder 1 in its axial direction by engaging a male screw thread 15 provided on the peripheral surface of the end wall 2, with a female screw thread 16 provided on the cylinder 1. To cause vibration of large amplitude, the end wall 2 is displaced outward and the moving region of the piston 6 is enlarged. To cause vibration of high frequency and small amplitude, the end wall 2 is displaced inward.

Title: Communication system by telephone set with id card reader
Inventor: YAMADA HIROO
IPC: H04Q3/58
Filed: 1988-02-12
Abstract: PURPOSE:To make a dial operation unnecessary by previously recording a special number for switching ID code classes, an ID code, and an access code to catch a trunk line trunk on an ID card and catching the trunk line trunk based on the access code read from the ID card by the ID card reader of a telephone set. CONSTITUTION:An ID card 10 is passed through a card reader 9, and the ID code class switching special number + the ID code + '0' are received at a registering circuit 8. The number '0', which is received last at the registering circuit 8, is recognized as trunk line transmission, and through a channel controller, the registering circuit 8 is disconnected, and a trunk line trunk circuit 11 is connected. At this time, a dial tone DT from NTT is sent to a PB telephone set 6. Thus, since the trunk line trunk is caught based on the access code read from the ID card 10 at the ID card reader 9 of the telephone set 6, the dial operation becomes unnecessary.

Title: Magnetic head
Inventor: TAKIZAWA KAZUNORI
IPC: G11B5/60
Filed: 1986-02-14
Abstract: PURPOSE:To improve a reproduction characteristic and also to simplify the processing with a magnetic head by setting a connection part at a place close to a slider together with a sloping surface formed at the outside of the connection part and at the same time avoiding a case where a recording/reproducing core is protruded over the sloping surface. CONSTITUTION:A slider 1 contains the 1st groove 1a extended in the single direction and the 2nd groove 1b extended in the direction orthogonal to the groove 1a. The connection parts 1c are formed at both ends of the groove 1a together with the sloping parts 1e formed at the outside of the part 1c respectively. The length of a recording/reproducing core 2 is kept within the part 1e in the direction of the groove 1a. Thus the area of the core 2 exposed over the rubbing face can be reduced, therefore, the externally induced noise and the rubbing noise can be reduced. In such a way, the reproduction properties of a magnetic head is improved. In addition, it is not required to set a special angle by forming previously a sloping surface. In such a way, a special tool nor a special working process for angle formation is omitted.
