IPC: H03J7/18
Filed: 1981-12-09
Abstract: PURPOSE:To store a station having better reception level at the district in a memory at all times, by storing data of a broadcast station of a suitable reception level in the memory automatically and replacing the data of the memory every time the reception area is changed. CONSTITUTION:Scanning is done over the entire band in a reception band and tuning data and reception levels for several stations can be stored in a memory 6c one after another automatically. Further, a control section 5 transfers the data of a memory section 6 into a data area 6b of stations to be checked, and is replaced with the content of a data area 6a for the station under reception at present, the reception level is discriminated, and when the station having the lower reception level is stored in the memory 6c as a result, the corresponding data are rewritten and the level is written at the same time. Thus, even if the reception area is changed, the broadcast station having a suitable reception level can be stored in the memory 6c automatically.

Title: Speech current limit circuit
Inventor: HARADA YASUTOSHI
IPC: H04M19/00
Filed: 1989-08-03
Abstract: PURPOSE:To eliminate the need for a large capacity capacitor and to reduce the cost by causing a current of each Zener diode to flow through a resistor interconnecting bases of transistors(TRs). CONSTITUTION:A base voltage made constant by Zener diodes 5, 5', a collector output of PNP TRs 4, 4' at a high potential side having a constant current circuit using an emitter resistor, a base voltage made constant by other Zener diodes, and a collector output of NPN TRs 4, 4' at a low potential side having a constant current circuit using an emitter resistor are used for a voltage supplied to a tip terminal 2 and a ring terminal 3 of a telephone subscriber circuit in a PBX. Then the current of each Zener diode flows through resistors 7, 7' interconnecting bases of the TRs. In this case, since the current flowing to the Zener diodes does not flow to a line between the tip terminal and the ring terminal, the impedance when viewing the TRs from a telephone set depends only on the collector. Thus, a large capacitance capacitor is not required.

Title: Acoustic unit
Inventor: INDEI NORIYUKI
IPC: H04R1/02
Filed: 1999-07-14
Abstract: PROBLEM TO BE SOLVED: To provide an acoustic unit of which operability is improved, which is constituted into multiple functions and whose availability is improved by arranging loudspeakers in a first housing and a second housing so that sound is emitted from the sides facing the outside in a state such that the housing are folded into two and are closed.

Either the first housing 32 emitting the sound of a left channel or the second housing 34 emitting the sound of a right channel is turned to a listener and therefore sound can concentrically be listened to in the loudspeaker 38 by being separated from the sound of the other channel. Even if an acoustic unit body 30 is folded into two, is closed and made in a compact state, respective switches 44, 46, 48, 50 and 53 are exposed to an outer part. Thus, a desired operation is executed without opening the first housing 32 and the second housing 34 so that operability is improved.

Abstract: PURPOSE:To enable accurate surface irregularity detection by directing a slit light to a specimen to project the reflected light to a screen, photographing the projected pattern with an ITV camera and differentiating the normal surface image pattern from the abnormal one. CONSTITUTION:A beam of wide slit light 3 id directed from a slit light generator 2 constructed of laser, cylindrical lens, etc. to a specimen 1 and its reflected beam 4 is projected for image development on a screen 5. The slit light 3 is directed to the specimen 1 at an angle of theta and then when, for example, the specimen 1 is of a flat surface without surface irregularity, the reflected beam 4 develops a linear bright image as shown by 'a' on the screen 5. When, any irregularity is present on the surface, the bright image of the linear characteristic is disturbed into distorted and swollen shaped as shown by 'b' through 'e'. These shape disturbances cause reduced light quantity of the liner characteristic.
