Title: Thermostat
Inventor: NAKAJIMA YOSHIFUSA
IPC: H01H37/12
Filed: 1990-11-21
Abstract: PURPOSE:To construct a cam in a small size and also lessening the width of a device frame by allowing an adjuster shaft to work as a stopper while the end face of the device frame protrusive part runs against the projection on the oversurface of the cam. CONSTITUTION:A projection 105 is furnished on a cam plane 104b of an adjuster shaft 104, and a device frame 101 protrusive part 103 having an end face 103a is allowed to come in contact with the projection 105. When this projection 105 on the cam plane 104b runs against the end face 103a of the protrusive part 103 of the device frame 101, the adjuster shaft 104 is not able to rotate, and utilization is made as a stopper of the adjuster shaft 104. This permits lessening the outside dimension of the cam and also lessening the width of the device frame 101, which enables a thermostat to be embodied in a small size.

IPC: G02F1/13
Filed: 1994-11-29
Abstract: PURPOSE: To easily judge whether or not a recording medium is already recorded without reading out an image by placing a line sensor in scanning operation or taking out the recording medium from a camera. CONSTITUTION: At the time of photographing operation, a light emitting element 71 is fixed in the ON state, an inspection exposure area provided outside the image area of an electronic development type recording medium 30 is exposed. In inspecting operation for exposure completion, the light emitting element 71 is fixed in the ON state first and the inspection exposure area of the electronic development type recording medium 30 is irradiated with light. The light transmitted through the electronic development type recording medium 30 is guided to the optical sensor 72. The optical sensor 72 measures the intensity of the transmitted light and it is judged, on the basis of the intensity, whether or not the electronic development type recording medium 30 is already recorded.

Title: Heat treat furnace
Inventor: TANAHASHI TAKASHI
IPC: H01L21/22
Filed: 1990-11-22
Abstract: PURPOSE:To enable the life of the magnetic seal part of a cover body to be lengthened by a method wherein a hollowed out part is provided in a heat retaining cylinder bed to heat the part beneath the supporting bed by the radiant heat from a heater while reducing the space of the supporting bed itself heated by the radiant heat so as to restrain the temperature rise. CONSTITUTION:When a boat 17 loaded with wafers together with a heat retaining cylinder 3 are inserted into a reaction tube 1 to be sealed later, the atmosphere beneath the heat retaining cylinder 3 is immediately raised by the hollowed out part of a heat retaining cylinder supporting bed 4. At this time, the radiant heat from a heater 2 heating the supporting bed 4 as well as the atmosphere beneath the retaining cylinder 3 by the hollowed out part is simultaneously received by a cover body 8 to be dissipated outward. Accordingly, this supporting bed 4 as well as a rotary axle 7 are not abnormally heated but to be kept at the temperature not exceeding a specific level using cold water. Through these procedures, the temperature of the supporting bed 4 can be restrained thereby enabling the life of a magnetic seal part of the cover body 8 to be lengthened.

The steel slab is rolled at >=1200 deg.C at >=5% total draft and further held at 1200-1100'C for >=20min to precipitate MnS, and then, solid-solution N as harmful component in the Al killed steel is precipitated in the form of AlN by using the MnS as nucleus. Subsequently, the rolled plate is finish-rolled at a temp. not lower than the Ar3 transformation point and then cooled rapidly at >=20 deg.C/sec cooling rate. Cooling is finished at 250-450 deg.C and the plate is held at the temp. for at least 60min to precipitate harmful solid-solution carbon as Fe3 C (cementite). By this method, the hot rolled steel plate, having non-aging characteristic of <=15MPa aging index AI and having excellent characteristics as substitutes for those of a cold rolled steel sheet, can be produced.

Abstract: PURPOSE: To realize noncontact detection of moisture in radioactive gas using a small-sized apparatus by measuring the concentration of H2 O through a noncontact absorption method using a semiconductor laser having wavelength corresponding to a combination tone present in near infrared region as a light source. CONSTITUTION: A semiconductor laser 1 connected with a power supply 2 delivers light through a half mirror 12 and an absorption cell 3 to a multiplier tube 4 which delivers an output through a differentiation circuit 5 to the power supply 2. The light reflected on the half mirror 12 passes through a punched disc chopper 10 and reflected on a mirror 13 toward an absorption cell 6 and then it is outputted to a photomultiplier tube 9. Output from the photomultiplier tune 9 is fed to a lock-in amplifier 11 which also receives an irradiation signal 10S from the chopper 10. The chopper 10 detects the times when the laser light is passed and blocked by a photodiode simultaneously with the chopping operation and outputs the detected times to the amplifier 11. Phase difference of signal outputted from the photomultiplier 9 is then detected and outputted as the concentration of moisture.

Filed: 1993-12-20
Abstract: PURPOSE:To attain selectively extending/contracting a car height adjusting unit by connecting a high pressure operating fluid chamber and high/low pressure operating fluid storage chambers by a communicating pipe with an opening/closing valve. CONSTITUTION:By opening an opening/closing valve 31a, a high pressure operating fluid chamber 17 communicates with high/low pressure operating fluid storage chambers 22, 24 to release a high pressure operating fluid in the high pressure operating fluid chamber 17 and the high pressure operating fluid storage chamber 22 to the low pressure operating fluid storage chamber 24, and a pressure of the high pressure operating fluid is lowered down to decrease car height. Accordingly, on-off getting can be easily performed even by a little person. During running, the high pressure operating fluid is accumulated in a high pressure operating fluid accumulator 33 through a check valve 32. Accordingly, when the check valve 32 is opened in a condition of low car height, the high pressure operating fluid in the high pressure operating fluid accumulator 33 passes through a communicating pipe 31 to flow into the high pressure operating fluid chamber 17 and the high pressure operating fluid storage chamber 22, and a pressure of the high pressure operating fluid rises to increase car height. Accordingly, even in a parking condition of low car height, the car height is immediately increased, and running can be started.

Title: Band variable filter and signal analyzer using the filter
Inventor: KISHI YUJI
IPC: H03H11/04
Filed: 1999-11-11
Abstract: PROBLEM TO BE SOLVED: To obtain a low noise output over the entire filter frequency from a narrow band to a broadband with immunity to an impedance change when the band of the filter is varied. SOLUTION: The filter frequency bandwidth of an input signal of a crystal vibrator 3a of the bandwidth variable filter 1 is freely varied in response to a varied impedance and controlling a current to a PIN diode 3b by a current control section 5 varies this impedance. A buffer circuit 4 consists of a pre-stage FET 7 and post-stage transistors(TRs) 8 in Darlington connection subjected to source follower and emitter follower respectively. Thus, even in the case that the filter frequency band is wide, the input impedance is high, a generated noise voltage is decreased to reduce the noise and a prescribed gain can be obtained.
