Title: Conductive paste and ceramic multilayer substrate
Inventor: NISHIDE MITSUYOSHI
IPC: B22F1/16
Filed: 1998-06-05
Abstract: PROBLEM TO BE SOLVED: To suppress warp and deformation of a ceramic multilayer substrate obtained by simultaneously baking a ceramic molded body and conductive paste for providing conductive sintered parts formed in and/or on the surface of the ceramic multilayer substrate. SOLUTION: A conductive paste is baked to form conductive sintered parts 3 of external conductors 5-7, internal conductors 8-12, and via holes 13-19, etc. Here, the contraction starting temperature at the time of baking is set higher than the contraction ending temperature at the time of baking a ceramic molded body for a ceramic sintered body 2 provided with ceramic layers 4, to prevent stress caused by the contraction of the conductive paste from acting on the ceramic molded body during its contraction at the time of simultaneous baking. For this purpose, a conductive ingredient contained in the conductive paste includes, for example, conductive powder comprising silver or metal containing silver as a main ingredient, coated with metal oxide having the melting point higher than that of silver.

Title: Flowing water detecting apparatus
Inventor: NIIMURA NORIO
IPC: G01P13/00
Filed: 1988-06-24
Abstract: PURPOSE:To enable the securing of a fail-safe characteristic by mounting a magnet on a water pressure detection rod interlocking with a diaphragm to detect the making and breaking of a lead relay mounted separated at a fixed interval therefrom. CONSTITUTION:A magnet 14 is mounted on a water pressure detection rod 13. A lead relay 15 is mounted on a body 1b of a water path 1 with a mounting device 16. When no water flows to the water path 1, the rod 13 and the magnet 14 have a spring 8 pressed against the bottom thereof together with a diaphragm 2 so that the magnet 14 is separated at a fixed interval from the relay 15 to break the relay 15. When water flows, the diaphragm 2, the rode 13 and the magnet 14 are pushed upward by a water pressure to make the relay 15 and the flowing water is detected with a control circuit 17. Thus, only when the relay 15 approaches the magnet 14, the flowing water is detected. In case the mounting device 16 of the relay 15 is broken, a fail-safe characteristic can be secured without detecting the flowing water by mistake.

Title: Roof window position and load detector
Inventor: HARADA HIROYUKI
IPC: B60J7/057
Filed: 1996-06-18
Abstract: PROBLEM TO BE SOLVED: To accurately detect any load acting on a window body and to promote a reduction in manufacturing cost. SOLUTION: A position of a window body is detected on the basis of the turning angle of a sensor plate 21 detected by a turning angle detecting means 261, and likewise any load acting on the window body is detected on the basis of a variation in rotational speed of the sensor plate 21 detected by a rotational speed detecting means 262. With this, the position of the window body corresponding to both ends of a neutral range is detectable without installing a first limit switch, detecting the position of the window body corresponding to one end of this neutral range and a second limit switch, detecting the position of the window body corresponding to the other end.

Title: Application device of photocatalyst and its production
Inventor: MIYAKE KAZUYA
IPC: B32B7/02
Filed: 1998-06-05
Abstract: PROBLEM TO BE SOLVED: To form a photocatalyst layer even on the objective surface of a material having large dimensional changes while suppressing peeling, and to increase varieties of products using a photocatalyst. SOLUTION: A sheet 1 on which a ceramic layer 2 having photocatalytic reaction is formed is joined to the objective face 8 of an apparatus 6 with an intermediate layer 5 having adhesion property. The dimensional changes with time and temp. of the face 8 are effectively absorbed by the intermediate layer 5 so that peeling of the ceramic layer 2 can be suppressed. Thus, the ceramic layer 2 can be formed even on the face having large dimensional changes, and varieties of products using a photocatalyst can be increased.

Title: Liquid metal surface level detector and surface level control system
Inventor: HIRAI EIICHI
IPC: G01F23/26
Filed: 1996-05-15
Abstract: PROBLEM TO BE SOLVED: To improve speed and accuracy for controlling a liquid metal surface level by performing processing to compensate a temperature of a detection coil and influence from disturbance and also performing wave detection at high speed with high accuracy. SOLUTION: Two detection secondary coils 22A, 22B are used to magnetically shield an upper detection coil so that a change in the lever of a liquid metal surface 24 functions only to a lower coil, thereby preventing detection balance between the coils 22A, 22B from being disturbed by influence of other disturbance. In addition, a sufficiently large fixed resistor is connected in series with the coils 22A, 22B and a thermosensitive magnetic material is placed in the vicinity of the coils 22A, 22B, wherein when a peripheral temperature varies, a change in temperature of the fixed resistor is small even if coil resistance of an excitation primary coil 21 and the coils 22A, 22B changes.  Thus a rate of change in resistance of the addition result is small, so that influence of the change in temperature is small while magnetic flux density in the vicinity of the coils 22A, 22B is stable by the thermosensitive magnetic material.

Abstract: PROBLEM TO BE SOLVED: To reduce the size and cost of a receiving attenuator controller by using a high-frequency switch, consisting of a semiconductor which is connected to an antenna, a transmitter part and a receiver part respectively, switches the signal paths and controls the attenuation of the signals received. SOLUTION: When an attenuator on/off signal(ADS) is set at an H-level in a receiving attenuation control mode, 1 and 3 of an analog switch(AS) 10 become conducting, and the output voltage of an attenuation control voltage generation part(AG) 11 is applied to a terminal V1 of a high-frequency switch(HS) 1. At the same time, a terminal V2 of the HS1 is set at an L-level and the D1 and D2 are both turned on. Then the output voltage of the AG 11 is controlled and the on states of D1 and D2 are also controlled. Thus, the impedance as seen from the HS1 receiving terminal can be changed. As the signal ADS is kept at an L-level in a normal receiving mode, 1 and 2 of the switch AS 10 become conducting and since both D1 and D2 are turned off, an antenna and the receiving terminal become conducting.
