Title: Electronic component
Inventor: MURAKAMI HIROMI
IPC: H01L23/50
Filed: 1989-03-02
Abstract: PURPOSE:To eliminate a drop in a melting temperature of a high-temperature solder by reducing an amount of a plated film at the inside of a resin which seals a main body and to prevent an accident of a short circuit at the inside and the outside of the resin by a method wherein a thickness of a solder-plated film at a tip part of a terminal including a connection part to the main body is made thinner than other parts. CONSTITUTION:The tip at the inside of a terminal 12 of an LC filter circuit is connected to a conductor pattern 3 formed at a side periphery part of a substrate 2 by using a solder 4. The substrate 2 on which a circuit element has been connected to the terminal 12 is sealed completely with a resin in a state that only the terminal 12 is exposed to the outside from a side face 13. Although a raw material 5 for the terminal 12 is plated with a solder, a film thickness of plated films is different at the inside and the outside of a resin 2. The film thickness of a plated film 14 at a tip part situated at the inside of the resin 8 is made thin; a plated film 15 at the outside is made thick. The film thickness of the thin plated film 14 is 2mum; that of the thick plated film 15 is about 10mum.

Title: Sound converter
Inventor: MATSUDA JUN
IPC: H04R23/00
Filed: 1988-03-04
Abstract: PURPOSE:To realize the favorable reproduction of a low band without making device constitution large-sized by controlling the temperature of gas adsorbent according to an input signal to be supplied to a heater controlling means. CONSTITUTION:When the input signal is larger (+) than a prescribed voltage level, the temperature of a heating part 2a is raised by controlling a heater device 2, and on the contrary, when it is smaller (-), the heating part 2a is cooled. A heater controlling means 3 controls the heater device 2 according to the input signal to be supplied, and controls the temperature of the gas adsorbent 1 through the heating part 2a. Thus, the adsorption quantity of gas by the gas adsorbent 1 changes correspondingly to the input signal. Owing to a fact that the quantity of the gas the adsorbent 1 adsorbs changes as corresponding especially to the low band component of the input signal, the rarefaction and the condensation of air pressure is caused around this gas adsorbent 1, and this rarefaction and this condensation are propagated as a sound wave.

Title: Sintered body of conductive ceramics and heater
Inventor: KUBO YUTAKA
IPC: C04B35/599
Filed: 1989-03-03
Abstract: PURPOSE:To suppress the rapid oxidation at 800 to 900 deg.C by adding a Cr oxide at a specific ratio to the above sintered body and heater consisting of silicon nitride ceramics contg. a conductive material at a specific ratio. CONSTITUTION:The sintered body and heater of the conductive ceramics consist of 10 to 70vol.% conductive compd., 0.1 to 10wt.% Cr oxide and the balance silicon nitride ceramics. This sintered body and heater are improved in oxidation resistance at 800 to 900 deg.C. The reason thereof lies conceivably in that the thick oxide film to be formed at >=1000 deg.C is not formed at a relatively low temp. of 800 to 900 deg.C and the oxygen in the atm. diffuses through the grain boundary phase in the sintered body to progress the oxidation, but the diffusion of the oxygen in the grain boundaries is suppressed by the addition of the Cr oxide. The effect does not manifest if the amt. of the Cr oxide to be added is below 0.1%. The sinterability is low if the amt. exceeds 10%.

Title: Contact sensor
Inventor: HIRATA TAKASHI
IPC: H01L41/08
Filed: 1995-02-03
Abstract: PURPOSE: To achieve a highly accurate detection regardless of the machining accuracy or contact direction of a sensor itself by vibrating a probe in contact with an object to be sensed. CONSTITUTION: A drive electrode 7 and a detection electrode 8 are laminated to a diaphragm 4 while holding a piezoelectric element 6 between them. A probe 9 is welded onto the diaphragm 4 with stainless wire. When an AC signal is applied to the drive electrode 7, the piezoelectric element 6 vibrates and the vibration is transferred to the probe 9. In this case, an AC signal with a voltage proportional to the level of vibration is generated at the detection electrode 8 due to the piezoelectric effect of the piezoelectric element 6. In this state, when the tip of the probe 9 touches a target, the vibration of the diaphragm 4 can be suppressed. Then, the vibration of the laminated piezoelectric element 6 can also be suppressed, and an AC signal appearing at the detection electrode 8 is also reduced. By processing the level of the AC signal by an electrical circuit, the presence or absence of contact can be detected.

In is required for the metallic foil that it has excellent heat resistance and corrosion resistance and a low specific heat and a high heat conductivity and is of low cost. Aluminium foil and its alloy foils are preferable among foils that can be used. Since a vessel formed by ultrasonic wave sealing of a metallic foil is used as a capsule, it is possible to present a heat accumulator suitable for latent heat accumulation of a small scale and a medium scale.
