Patent JP-H0197069-A (JP)
Title: Gamma-correcting circuit
Inventor: HARA KEN
IPC: H04N5/202
Filed: 1987-10-09
Abstract: PURPOSE:To reduce unnecessary capacity and to use voltage-dividing resistances for the video circuit of a high frequency band by constituting a switch circuit through the use of a switching transistor and permitting it to select the voltage- dividing resistances changing the amplitude of an input signal. CONSTITUTION:In a state that the input signal is not supplied to an input terminal 1, a voltage (potential) E0 which is obtained by voltage-dividing a supply voltage +B in the resistances 18 and 19 of the switch circuit 11 is impressed on the base of a switching transistor 13. When the input signal is supplied to the input terminal 1, the input signal is outputted from the emitter of an impedance converting transistor 2 to the base of the switching transistor 12. When the input signal is large and the base potential of the transistor 12 becomes lower than E0, the switching transistor 14 comes to a conductive state, and the input signal is voltage-divided in both resistances 3 and 6, whereby the amplitude becomes small. When the input signal becomes small, the base potential of the transistor 12 drops less than E0, and the transistor 14 comes to a non-conductive state, whereby the input signal is outputted through the division resistance 3.

Title: Spinning liquid for tin oxide fiber and production of tin oxide fiber
Inventor: YAMASHITA HIROYA
IPC: D01F9/08
Filed: 1995-10-02
Abstract: PROBLEM TO BE SOLVED: To obtain the subject fiber not causing deformation of yarn shape by humidity in the atmosphere in spinning and/or after spinning by dissolving a tin compound and a metal compound in an alcohol to afford the spinning solution and spinning the solution. SOLUTION: This spinning solution comprises dissolving (A) an alcohol-soluble tin compound and (B) a metal tin into an alcohol (preferably methyl alcohol or ethyl alcohol capable of dissolving a tin halide compound with high solubility). The spinning solution is spun to produce the objective tin oxide fiber. Thereby, moisture resistance of gel fiber is remarkably improved and softening and attachment of the fiber to the fiber due to humidity in the atmosphere is decreased.

Title: Detection circuit of picture recording mode of picture recording/playback apparatus
Inventor: JIYO SHIYOUSHIYU
IPC: G11B19/12
Filed: 1993-10-13
Abstract: PURPOSE: To provide a video recording/reproducing device provided with a mode judging circuit which is more suitable for high integration conversion and is capable of efficiently and easily judging a video recording mode. CONSTITUTION: The peak values of frequency difference signals fH and 3fH between pilot signals are detected by peak value detectors 30 and 40, compared by a comparator 50 and, after that, integrated by integration circuits (R1 and 1). The potential state of the signals are judged by a trigger level set in a Schmitt trigger circuit 60 and, as a result, a mode discriminating signal where a logical state is changed is outputted from the Schmitt trigger circuit 60. The potential state at an input end C is changed corresponding to the frequencies of the signals fH and 3fH, that is, the close-packing degree of a pulse string in output ends A and B.

Title: Ventilation method for wooden building
Inventor: YOSHIDA TATSUZO
IPC: F24F7/10
Filed: 1984-12-04
Abstract: PURPOSE:To enable a desired indoor condition to be attained by a method wherein an adjusted and requested humidity and a temperature signal are compared by a manual switch and a driving of a ventilation fan is controlled. CONSTITUTION:A requested operation humidity signal C adjusted by a humidity switch S of a manual switch 14 and a requested operation temperature signal (d) adjusted by a temperature switch T are compared at the control part 13. When the humidity in the under-floor space 1 and the temperature of the rear- ceiling space 3 are coincided with or higher than each of the adjusted and requested operation humidity and the temperature, the ventilation fan 6 is driven, the air in the space 1, inter-wall space 2 and the space 3 are discharged out and the circulation air space A is ventilated. If the manual switch 14 is changed over to its non-automatic change-over switch 15, the driving signal (g) is sent back to the control part 13 and so the ventilation fan 6 can always be driven. In turn, the stop signal (h) is sent, the ventilation fan 6 can be stopped. As a result, it is possible to make a desired interior condition.

Title: Ethylene-propylene rubber composite and production thereof
Inventor: TABUCHI KAZUO
IPC: B32B25/08
Filed: 1989-09-29
Abstract: PURPOSE:To enable the application of an ethylene-propylene(EP) rubber-formed article having excellent resistance to weather by allowing a tacky material to adhere to at least one surface of the EP rubber-formed article via a heat activation type adhesive layer. CONSTITUTION:A tacky material 2 is made to adhere to at least one surface of an EP rubber-formed article via a heat activation type adhesive layer 1. That is, an EP rubber composite has the heat activation type adhesive layer 1 interposed between the EP rubberformed article and the tacky material 2, and they are pressed under heating and laminated integrally. The adhesive 1 is a composition mainly composed of a compound having a molecular structure similar to those of both of the EP rubber and the tacky material 2, and since the adhesive 1 shows affinity to both of the EP rubber and the tacky material 2 due to its molecular structure, it well penetrates even into fine spaces on the surfaces to produce an anchor effect and exhibits excellent adhesive properties. Accordingly, the adhesive 1 effectively works with respect to the EP rubber which has hardly adhesive properties, and the EP rubber and the tacky material can strongly be made into one body.

Title: Injection catheter for artificial insemination
Inventor: INOUE TAMOTSU
IPC: A61M25/00
Filed: 1987-10-13
Abstract: PURPOSE:To surely suck high-concentration semen without block with vaginal foreign substances at the time of insertion, by stopping the tip of a catheter tube, and by providing only the cross-sectional unilateral region on the tip side with a side hole communicating with the inside and outside of the tube. CONSTITUTION:After the catheter tube 12 of a catheter 10 is inserted gradually from vaginal 16 into the opening of uterus 17, semen is slowly injected into intrauterine cavity 18. Since the tip of the catheter tube 12 is not open, vaginal foreign substances are prevented from invading into the catheter tube 12 or from adhering to side hole 13, resulting in no block of the semen injection path of the catheter tube 12. When a small volume of semen present on the bottom of a test tube set in inclivation is to be sucked into syringe barrel 11, turning the catheter tube 12 with side hole 13 downward to the bottom of the test tube allows suction of the whole semen. As a result, high-concentration semen can surely be sucked.

Title: Correcting method of disturbance when break of tool is detected
Inventor: SUGINO KENJI
IPC: B23Q17/09
Filed: 1984-12-04
Abstract: PURPOSE:To enable a break trouble in a tool to be detected, by using a difference between an idle time at the present machining time and an idle time at machining time in a process immediately before the present machining time as the idle time difference. CONSTITUTION:The method assumes A for an idle time, beta for a preset value further the preset value beta for a sum of a fixed value beta1 and a variable value alphacorresponding to a change of air pressure in an operational power supply. The variable value alpha is used as a function of the idle time at machining time in the present process and in a process immediately before the present process, and a break in a drill is detected by comparing in relation an idle time difference An-An-1 with the preset value beta=beta1+{(An-1/An-2)-1}. And when the pressure of air tends to decrease, the tool, increasing the value beta1+alpha and a permissible value of the idle time difference because the value alpha={(An-1/An-2)-1} increases, becomes able to correspond to an increase of the idle time due to a decrease of a feed speed. Similarly when the pressure of air tends to increase, the tool becomes able to correspond to a decrease of the idle time.
