Title: Package for housing electronic component
Inventor: SUZUKI MAKI
IPC: H01L23/08
Filed: 1999-12-21
Abstract: PROBLEM TO BE SOLVED: To provide a package having a high reliability in sealing. SOLUTION: The package for housing an electronic component consists of the main body 1 and a metal cover body 2. The main body 1 of the package includes a mounting section 4 for mounting an electronic component 3 and a ceramic frame body 6 surrounding the mounting section 4, which are disposed on the upper surface of a nearly flat substrate 5, and a metallized layer 9 for sealing which is attached to the upper surface of the ceramic frame body 6. The metal cover body 2 is welded to the metallized layer 9 through a solder material 10. The ceramic frame body 6 is formed with a rounded part 11 having a radius of about 5 to 50 mm from the upper surface toward the outer side face. The periphery of the metallized layer 9 is extended to the middle of the rounded part 11.  After welding the metal cover body 2 to the metallized layer 9, residual stress pulling the periphery of the metallized layer 9 inwards is distributed by the rounded part 11, effectively preventing the metallized layer 9 from peeling.

Inventor: SUGIYAMA OSAMU
IPC: E06B7/14
Filed: 1997-12-09
Abstract: PROBLEM TO BE SOLVED: To provide a method by which rainwater entering a building frame from parts of an exterior wall that are defective in terms of watertightness is drained again to the outside without leaking indoors.

Title: Portable sound recording/reproducing device
Inventor: BEPPU SHIGEYUKI
IPC: G10L19/00
Filed: 1998-12-25
Abstract: PROBLEM TO BE SOLVED: To enable a user to select and change recording time in accordance with a purpose by determining sampling frequency based on the selected recording time, sampling a sound signal inputted by the determined frequency, converting the sampled signal into a digital signal, and recording the digital signal in a semiconductor memory. SOLUTION: In the case of extending recording time e.g. twice, recording time to be twice as long as normal recording time is selected and inputted by an input means 6. A CPU 5 sets up the recording time to twice and sets up sampling frequency to a half of a prescribed value in order to extend the recording time twice. When a recording start button is depressed in the state, the CPU 5 supplies the sampling frequency set up to a half to a recording/ reproducing IC 3, which is allowed to execute recording operation. Since a sound signal inputted from the sound input part 1 is sampled by a half of the prescribed frequency value and converted into a digital signal in the recording, data volume to be recorded in an IC memory 4 is a half of that for normal recording.

Title: Equalized amplifier
Inventor: KOMIYA TAKESHI
IPC: H03F1/34
Filed: 1999-12-28
Abstract: PROBLEM TO BE SOLVED: To normally operate DC feedback control even if a preamplifier operates in a saturated state in an equalized amplifier, for which the peak detection of the amplitude of an output signal is utilized. SOLUTION: A first peak detecting circuit 26 performs the peak detection of the amplitudes of output signals having positive and negative phases from a preamplifier 21 and detects whether or not gain saturation occurs in the preamplifier 21 on the basis of the detected result. When the gain saturation occurs in the preamplifier 21 as a result of the detection, the gain of a differential amplifier 31 becomes low, DC feedback control is prevented from being unstable and the threshold voltage of an abnormal value is prevented from being outputted to the preamplifier 21. When the gain saturation does not occur in the preamplifier 21, on the other hand, the gain of the differential amplifier 31 becomes high and DC offset is canceled.
