Title: Horizontal deflection driver circuit
Inventor: TAKAKOSHI AKIRA
IPC: H04N3/16
Filed: 1978-06-24
Abstract: PURPOSE:To prevent the breakdown of the horizontal output transistor of the display unit using CRT with no oscillator, by stopping a horizontal deflection driver circuit from operating when a horizontal synchronizing signal is disturbed. CONSTITUTION:Horizontal synchronizing signal (a) from terminal IN1 is amplified by transistor TRTr3 and supplied to the frequency-voltage converter composed of diode D2 and capacitor C6 via direct-current cutting capacitor C4. Its output (d) is inputted to one terminal of comparator Z1 and reference voltage Vref divided by resistances R6 and R7 is to the other while the output of comparator Z1 is made open in a normal state by setting. Once the frequency of the horizontal synchronizing signal decreases, voltage Vd becomes below reference voltage Vref and comparator Z1 is shorted to cut off TRTr1, so that the horizontal deflection driver circuit will stop operating. Horizontal output transistor Tr2 can therefore be prevented from breaking down.

Title: Converter lens
Inventor: TANAKA KAZUO
IPC: G02B15/10
Filed: 1986-04-02
Abstract: PURPOSE:To reduce the size of the whole system body and to obtain the excellent optical performance of a semitelephoto type which is about 25-30 deg. in photographic field angle when a converter lens is mounted by employing a rear converter system and specifying the lens constitution. CONSTITUTION:The lens surface of the 1st lens on an image plane side is made convex and the lens surface of the 2nd lens on an object side is brought to negative refracting power to set the shapes of both lenses properly, thereby compensating the spherical aberration. A converter lens is composed of three lenses having a positive, a negative, and a positive refractive index and an increase in Petzval sum is reduced as much as possible to prevent curvature of field from increasing. Meniscus lenses which have convex surfaces on the image plane side are used as the 1st and the 2nd lenses to reduce the generation of the comatic aberration of the whole image plane. The negative distortion when the converter lens is mounted is compensated by making the image-side lens surface of the 3rd lens convex.

Title: Camera provided with switching type variable power optical system
Inventor: OGAWA YUKIO
IPC: G03B17/12
Filed: 1986-04-02
Abstract: PURPOSE:To prevent a camera body from becoming longer in the horizontal direction, by moving a partial optical member of a photographic optical system in the direction being orthogonal to a photographic optical axis, and also, being orthogonal to the running direction of a photosensitive surface. CONSTITUTION:At the time of switching a standard photographing state to a telephotographing state, it is executed by moving a lens barrel 7 in the lower direction (the direction as indicated with an arrow A) so that an optical axis of a main lens system 1 is positioned on the front optical axis of a sub-lens system 2. In such a state, in case of telephotographing, a luminous flux from an object to be photographed 20, which is made incident on the main lens system 1 is reflected by the first reflecting mirror 3 and the second reflecting mirror 4 through a shutter 5 and the sub-lens system 2, and thereafter, the light is led to a photosensitive surface 6. In such a way, it becomes unnecessary to widen an interval between a spool chamber and a cartridge chamber, therefore, it can be prevented that a camera body becomes long in the horizontal direction.

Title: Information recording medium
Inventor: MATSUBARA KUNIHIRO
IPC: G11B7/24024
Filed: 1984-04-16
Abstract: PURPOSE:To minimize the deterioration of a recording film without causing exfoliation of a bonded part even under the environment of high temperature and high humidity by bonding two disc bases fully with an optical guide groove and an optical recording film by means of an adhesive of distortion absorbing performance with less elastic coefficient. CONSTITUTION:The optical guide pit 2 is provided to the disc base 1a and the optical recording film 3 is vapor-deposited. The disc base 1 made as above is bonded fully with the disc base 1b made of polycarbonate resin similarly while taking the optical recording film to the inside by means of the photocuring elastic adhesives 6. Thus, the disc base tends to leave the internal stress due to thermal distortion and the distortion by the stress is generated conversely under the condition of high temperature and high humidity. However, the adhesive 6 itself has an elasticity through the constitution above and it is smaller than the elastic coefficient of the disc base, then even if a minute distortion is produced on the disc base 1a, the elastic adhesives 6 follows up the distortion and no exfoliation takes place.

Abstract: PURPOSE:To perform comfortable driving by switching periodically among the selected direction and other blow out directions except for the defrost direction until the heater capability is increased to a predetermined value or more and the room temperature reaches a predetermined value provided that the blow out directions other than the defrost blow out direction are selected. CONSTITUTION:When an ignition switch 31 is turned on and a mode switch 23 is selected at a foot mode, the blow out mode becomes a defrost mode if a water temperature switch 18 is at a predetermined temperature or less, and a fan 2 is operated at a low speed. Next, when the water temperature is increased to the predetermined value or higher and before the room temperature reaches the predetermined value of a temperature switch 19, the blow out mode is changed periodically among the foot mode, high level mode, or face mode, thus increasing the room temperature rapidly. When the room temperature reaches the predetermined value, a timer relay 30 is turned off and the blow out direction is fixed at the foot mode. Accordingly, the glass frost is prevented and also the room temperature is increased uniformly and rapidly, thereby safe and comfortable driving can be performed.

Filed: 1988-03-31
Abstract: PURPOSE:To lower a temperature of an object to be treated, by providing a layer for transmitting ultraviolet rays and shielding heat rays between an ultraviolet light source and the object to be treated. CONSTITUTION:A vessel 4 having a thin space layer 30 is formed of synthetic quartz plates with thickness of 1-1.5mm which can transmit ultraviolet rays of 200nm or less. Thus, the vessel 4 allows ultraviolet rays to reach an object to be treated 5. Since the vessel 4 is formed of quartz that transmits infrared rays having a wavelength up to 4mum, the vessel transmits heat radiation rays from the heated walls of an ultraviolet radiation supply 2. Therefore, a temperature of the object 5 is raised to 150-200 deg.C by heat radiation even after stopping supply of power to a heater 7 of a stage 6. In order to treat the object 5 at a low temperature, pure water which transmits ultraviolet rays and absorbs heat rays with wavelength of 1-1.5mum or over is supplied through the thin space layer 30 defined by the vessel 4, so that the temperature of the object 5 can be lowered to 100 deg.C or less.

Abstract: PURPOSE:To allow two timings to coincide with each other in a simple constitution, by switching the phase of a reference signal at the detection timing of a phase switching timing detection means when the polarity of the pulse outputted from the phase switching timing detection means is switched three or more times continuously. CONSTITUTION:A switching timing 11 of the phase of an input signal and a switching timing 16 of the phase of the reference signal are detected by an ID detector 20 interruptedly in accordance with their switching periods, and the pulse having the same polarity is outputted if both timings coincide with each other, and the pulse having the opposite polarity is outputted if they do not coincide with each other. If the polarity of this pulse is changed at least three times continuously, the phase of the reference signal is forcibly switched by a switch control circuit 21. Thus, the phase switching timing of the input signal and that of the reference signal are allowed to coincide with each other by the simple constitution where the change of the polarity of the pulse is decided only.
