Title: Jar pot
Inventor: NIIYAMA TORU
IPC: A47J41/00
Filed: 1987-12-18
Abstract: PURPOSE: To prevent water from splashing around, by lowering output of a pump to reduce the water delivery amount to blow air out with water when the water level comes to a level lower than the level of a water level sensor. CONSTITUTION: Since a float 14 comes down to the level of an LED 11 and a phototransistor 12 when the water level is at a place lower than a water level sensor 6 upon closing a drive switch 8, the light of the LED 11 cannot reach the phototransistor 12, interrupted by the float 14, and the phototransistor 12 is not turned ON. The voltage at the plus side input terminal of a comparator 19 is higher than the voltage at the minus side input terminal divided by resistances 17 and 18, and the output of the comparator 19 comes to the high level to stop a drive signal to a bidirectional thyristor 21.  Thus, since the bidirectional thyristor 21 is turned ON, power supply to a solenoid coil 23 is made through a resistance 22, and the voltage applied to the solenoid coil 23 is lowered compared to the case when the bidirectional thyristor 21 is turned ON, thus the delivery amount of water is reduced.

Title: Terminal metal
Inventor: ATSUMI KEIGO
IPC: H01R4/24
Filed: 1996-12-03
Abstract: PROBLEM TO BE SOLVED: To eliminate need of caulking work to a wire. SOLUTION: A back end part of a side wall 21 is folded inward to compose a wire holding part 20. A back edge part of the side wall 21 is diagonally protruded forward, and then bent outward, so an elastic piece part 22 and a holding part 22B ate formed, and a tip of the elastic piece part 22 is folded inward to form a crimp blade 23. As a wire crimped by the blade 23 is pulled backward, the elastic piece part 22 is elastically deformed inward about the center of a folded part 22A, so the wire is strongly held by the holding part 22B. Move of the wire can thus be regulated even without caulking the wire by a barrel member or the like, thereby need of caulking work to the barrel member or the like can be eliminated.

Title: Urine sampling apparatus and urine sampling apparatus with container
Inventor: PEETAA RATSUSHI
IPC: G01N1/10
Filed: 1989-12-13
Abstract: PURPOSE: To automatically collect a sample from intermediately discharged urine so as to substantially prevent the contamination of the sample by making the urine to flow to a drainage after sufficiently raising the surface level of the urine in a container. CONSTITUTION: Urine flows down to a flowing-out port fixed by means of a plug 64 through a funnel-like member 62 and then flows in a container 40 through a discharge pipe 32. The surface level of the urine gradually rises in the container 40 until the urine covers a chamfered discharge port 34, but the urine discharged thereafter does not flow in the container 40, but stays in the member 62 until the surface level reaches the upper end section of the member 62. Then the urine overflows the upper end of the member 62 and stays on the bottom of the container 12 together with the initially discharged urine left in the container 12. When the surface level of the urine in the container 12 sufficiently rises, the urine flows in a drainage 20. Usually, the overflowing urine flows to a toilet stool until the excretion of the urine is completed.  When the urine flows to the stool, the container 12 and a float chamber 16 become empty, because the urine in the container 12 and chamber 16 is discharged.

Title: Protective circuite device of switching transistor
Inventor: HAINTSUUDEIITOMARU KAARU
IPC: H02H9/04
Filed: 1988-12-23
Abstract: PURPOSE: To reduce the ON/OFF ratio of a pulse outputted from a pulse width modulator to control a switching transistor(TR) and to continuously drive the switching TR by reducing a current flowing into a line or a leaked inductor when the excess voltage state of feed voltage is continued. CONSTITUTION: At the occurance of excess voltage, a Zener diode 1 acting as a voltage limiting diode is turned to a conductive state. A current flowing in the voltage limiting diode charges a capacitor 7 through a diode 4. The ON/OFF ratio of a pulse outputted from the pulse width modulator 11 is reduced by a discharge current discharged from the capacitor 7 through a discharge resistor 8. Consequently a switching current, i.e., switching voltage, flowing in the switching TR 2 is reduced, and at the occurance of excess voltage, the TR 2 is protected and the switching operation is also continuously driven.

Title: Forming method of small-gage wire
Inventor: IZUMI MOICHI
IPC: H01L21/306
Filed: 1991-11-11
Abstract: PURPOSE:To form a small-gage wire simply with excellent reproducibility by etching a semi-insulating GaAs substrate by a first solution, treating the etched semi-insulating GaAs substrate by a second solution and epitaxial-growing the treated semi-insulating GaAs substrate. CONSTITUTION:SiO2 films 2 are patterned and formed so as to cover sections, to which small-gage wires must be shaped, in a semi-insulating GaAs substrate 1 first. GaAs surfaces not covered with the SiO2 films 2 are etched for two min by H2SO4:H2O:H2O2 as a first solution. The SiO2 layers 2 are removed by HF:H2O as a second solution, and GaAs surfaces 4 after removal are pretreated. An I-AlGaAs layer 3 is formed through one-time epitaxial growth. When a crystal is grown by using molecular-beam epitaxial crystal growth normally, impurity segregation is generated in the surface of the GaAs substrate 1 through heating pretreatment. The segregation of carriers is generated only in an HF group treated region 4, to which H2SO4 group treatment is not conducted in this invention, and the small-gage wires are formed to the sections.

Filed: 1992-12-03
Abstract: PURPOSE:To always be offset amount of rough zero, to eliminate lightness difference every device and to automatically perform the black level adjustment of an image signal by reading the image within the field of view of an image sensor from the image signal from an image sensor and correcting the black level of the image signal from the bit which is outside of the field of view in a black level correcting device. CONSTITUTION:A black area detection circuit 17 detects and holds the image signal of the part which is within a CCD field of view for which a light shielding is not performed by a mask M in the photoelement PE of a CCD 11 and is the outside of the field of view of an image sensor from the image signal from an arithmetic circuit 14. A differential amplifier 18 takes the difference between the output signal of a black area detection circuit 17 and the reference voltage Vref from a reference voltage source and outputs this to an arithmetic circuit 14. Therefore, image is read within the field of view from the image sensor and the black level of the image signal from the bit which is the outside of the field of view is corrected by a black level correcting device. Thus, the offset amount of the image signal from the circuit 14 always becomes the offset amount of rough zero and the lightness difference of the device is eliminated.
