Title: Guidance system of flying body
Inventor: MIHARA SOUICHIROU
IPC: F41G7/20
Filed: 1980-02-06
Abstract: PURPOSE:To guide a flying body to the target body with high guidance accuracy, by adding an angular velocity of the eyes angle and angular acceleration of the eyes angle, of the target body, to the steering input. CONSTITUTION:An angular velocity of the eyes angle to the target body is detected by the angular velocity detecting circuit 8, and is provided to the amplifier 9. Also, an angular acceleration of the eyes angle is detected by the angular acceleration detecting circuit 10, and is provided to the amplifier 11. And, the output of the amplifier 5, showing a deviation RME of the flying body against the eyes of the target body, and the outputs of the amplifiers 9, 11 are added by the adder 12, and the result is made a steering input of the flying body. In this way, since the angular velocity and the angular acceleration are added to the steering input of the flying body, a proper steering input is provided even if the flying body is on the eyes of the target, therefore the flying body can be guided to the target with high guidance accuracy.

Title: Method and device for generating dummy target signal
Inventor: WATANABE MASAHIRO
IPC: G01S7/40
Filed: 1989-01-23
Abstract: PURPOSE:To generate a signal which is closer to a signal reflected by an actual target by varying the speed and distance of a dummy target in consideration of acceleration. CONSTITUTION:A 1st speed counting part4 receives a speed information signal (a) and generates a smoothing clock signal 14 at intervals of time required to move the target at the speed by a distance corresponding to distance resolution. When the acceleration of the dummy target is extremely large, the distance of the dummy target varies greatly in each cycle of the signal 14, so a 3rd frequency division part 5 varies the frequency of the reference signal from a reference signal generation part 1 through a 1st phase adjustment part 2 according to an acceleration information signal (b) and a 3rd speed counting part 6 generates the smoothing clock signal 15 at intervals of time required to move the target at the speed varying with acceleration by the distance corresponding to the distance resolution. The address of a storage part 9 where the information of the signal (a) is written is changed in each cycle of the signal 15.

Filed: 1996-01-30
Abstract: PROBLEM TO BE SOLVED: To reduce number of part items of a door lock by retractably providing a stopper cam projected from the circumferential surface of a lock cam which rotates in association with a thumb turn knob in a rotating region of a rotation cam which is rotatable integrally with a lever handle. SOLUTION: A lock cam 52, which has a stopper cam 53 projecting from the circumferential surface thereof and rotates in association with a thumb turn knob, is provided in a rotation region of a rotation cam 8. For locking a door, the thumb turn knob is operated from the inside of the door. A lock bar 55 turns and the forward end of the cam 53 is engaged with the circumferential surface of the stop cam 12 to prevent the rotation of the cam 8. For releasing the door, the knob is turned in the opposite direction. The lock bar 55 turns in a direction opposite to the direction at the time of the locking. The forward end of the cam 53 is retracted from the circumferential surface of the stop cam 12 and the cam 8 becomes rotatable. If a lever handle is turned, the cam 8 rotates and a latch bolt 34 is retracted to open the door.  As a result, an inexpensive door lock of simple construction can be obtained.

Title: Hot water supply equipment
Inventor: ADACHI KAZUHIRO
IPC: F24H1/18
Filed: 1988-01-25
Abstract: PURPOSE:To prevent a rise in electricity charge due to a continuous supply of electric power to a heater, by providing a thermostat for temperature control to a heater installed to a feed water piping, and fixing said thermostat with a black-colored metal fittings at the central position of a drum member in the height direction. CONSTITUTION:The contact of a thermostat 7 is turned ON when the outside temperature drops in winter, which turns ON a heater 9, thereby preventing freezing in a feed water piping 6. At the same time, hot water obtained by the combustion of a hot water supply device is produced within a drum 1. Therefore, the hot water within said drum 1 radiates heat to the parts which surround the drum 1. In other words, the surroundings around the drum 1 are subjected to radiation heat irradiated from the drum 1. At this time, the thermostat 7, which is designed for the ON/OFF control of the heater 9 is installed in the internal surface of an outer covering, and in the central position of the drum in the height direction. Moreover, the surface is fixed with a black colored metal fittings 8. As a result, a great deal of radiation heat can be absorbed. Therefore, the contact of the thermostat 7 is turned OFF in the case of lower outside temperature where the temperature fails to rise, which turns OFF the heater 9 as well. It is, therefore, possible to prevent the heater 9 from passing electric power continuously even when the outside temperature is low in winter.

Title: Electric motor rotor and its manufacture
Inventor: KATAOKA HISAKAZU
IPC: H02K1/27
Filed: 1999-01-22
Abstract: PROBLEM TO BE SOLVED: To provide a high quality electric motor with low-level noise. SOLUTION: When the number of poles is P, P or more joining means such as caulking exist at the inner- and outer-peripheral sides in the diametrical direction of at least a permanent magnet 12, namely, 2P or more joining means such as the caulking exist in total. In this case, since the joining force due to caulking 13a at the inner-peripheral side of the diameter direction is made stronger than that due to caulking 13b at the outer-peripheral side of the diameter direction, thus increasing the stiffness of a rotor, decreasing the noise level, improving rotor inner diameter cylinder accuracy, and hence providing a quality, reliable, and superior electric motor.

Title: Development density measuring method
Inventor: SAKAMOTO KOUJI
IPC: G03G13/08
Filed: 1979-02-09
Abstract: PURPOSE: To perform accurate measurement by saturation-charging the development toner prior to measurement of development toner potentials.  
     CONSTITUTION: The standard image of a fixed density is projected onto the surface of a photosensitive drum 1 through a lens 3. After the latent image tube formed is developed with a developing device 4, corona is discharged by a transfer charger 12 until the toner particles of the toner image charge to saturation, thereafter light  is radiated by a lamp 17 over the entire part of the toner image portion and the  photoreceptor surface of the peripheral edges and lower side of the toner image are destaticized. Thence, the potentials of the toner image are detected with a potential detecting electrode 18 and amplifier 19. According to the detecting value, the toner is replenished into a developer container 6. This makes possible the accurate detection of the toner amount by making use of the nature that the toner cannot hold the charges of more than a fixed charged amount.

Abstract: PURPOSE: To make it possible that the magnetic tape recorded by a large-diameter magnetic recording device is reproduced by a small-diameter rotary magnetic head reproducing device, by correcting the reproducing tracking locus on the magnetic tape so that this locus may pass on the recording track.  
     CONSTITUTION: In respect to two-head type rotary magnetic heads, the X system and the Y system are set for the large-diameter magnetic recording device and the small-diameter VTR device respectively, and the diameter of the video head of the X system and the Y system are defined as 74.487mm and 62.000mm respectively. For tracking on recording track TX, which is recorded by the X system, with video head 1 of the VTR of the Y system, a structure is given where video head 1 is supported by bimorph plate 7 of an electromechanical conversion element. Since the bend degree is changed when a voltage is applied to bimorph plate 7, tracking correction is so performed that tracking locus UY may be superposed onto recording track TX, so that the exchange use between VTRs different in recording system is possible.
