Title: Cassette tape player
Inventor: OTEGI YUUZOU
IPC: G11B15/10
Filed: 1984-12-29
Abstract: PURPOSE:To omit an independent space for a muting switch and to increase degree of freedom for the designing of a cassette tape player together with miniaturization, by unifying a mobile bar of a leaf switch with a lock member for a toothless gear. CONSTITUTION:A switching arm 73 has a contact with a mobile piece 93a of a leaf switch 93 forming a muting switch for the end face at the other side of the arm 73. Thus the bar 93ais shifted. A engaging member 83 engaging the engaging recesses 81a and 81b of a lack gear 81 is unified with the bar 93a. When the engaging state of the member 83 is released, the gear 81 engages a pinion gear 86. Thus the next recess 81b is set opposite to the gear 68 and kept in this state until the member 83 engages a engaging recess 81e. In such a way, the member 83 is put on a cam surface 81f until the member 83 engages the next engaging recess after the member 83 is once removed from an engaging recess. Thus a muting state is held until a reverse mode is through.

Title: Data input device
Inventor: ANDO MUNENORI
IPC: G06F3/02
Filed: 1987-11-07
Abstract: PURPOSE:To change referring data to desired referring data simply and without fail even after the referring data are defined by reading a code address stored and held beforehand and correcting it when the referring data are changed after the code address is inputted and the referring data corresponding to the code address are defined. CONSTITUTION:The displayed code address is visually read and the code address is corrected by a correcting means 4. At present, when a 'electric calculator DC-400' is inputted and a 'digital clock WT-20' is inputted, the code address is inputted and corrected to 'den' (the square form of KANA) by adding 'ng' (the square form of KANA) to 'de' (the square form of KANA). Thus, when the corrected code address 'den' (the square form of KANA) is converted to the referring data to show a desired product name 'electric calculator DC-400' by a code address table 1, it is inputted and defined to an input area. Consequently, even after the referring data are defined, the referring data can be changed to desired referring data simply and without fail.

Title: High frequency semiconductor integrated circuit
Inventor: KANAZAWA KUNIHIKO
IPC: H01L21/822
Filed: 1989-10-30
Abstract: PURPOSE:To form a small-sized monolithic microwave IC(MMIC) by arranging dielectrics having relative permittivity larger than that of a semiconductor substrate, on the rear of the substrate having electronic circuits on the surface. CONSTITUTION:Wiring metal 2 is formed on a semiconductor substrate 1, and an ordinary MMIC is constituted. An insulating film is usually sandwiched between the substrate and the wiring metal, and a protective film is used on the wiring metal. On the rear of the MMIC, dielectrics 5 having a relative permittivity larger than that of the semiconductor substrate is stuck by using adhesive agent 4. Since the dielectrics 5 whose relative permittivity epsiloneff is larger than that of the semiconductor substrate is used, the electric wavelength on the wiring metal becomes 1/epsiloneff times. Hence it becomes about 1/3 of a GaAs substrate, and the chip area can be reduced by a fraction of about 10. Thereby the chip area can be reduced.
