Title: Guiding device for flying object
Inventor: KASHIWAZAKI SHIGEMI
IPC: G05D1/12
Filed: 1986-03-05
Abstract: PURPOSE:To guide a flying object so that the proportional navigation is completely secured even though the speed of the flying object or a target is changed, by correcting the course angle of the flying object in response to the speed change and using this correction signal to give the steering control to the flying object. CONSTITUTION:The time factor dlambda/dt of the viewing angle lambda detected by a detecting part 11 is sent to a correcting part 14 in the form of the guide signal. While the anticipative angle L detected by a detecting part 15 is sent to an output part 16. The part 16 supplies the relative speed VC between a flying object and a target together with the angle L to obtain a correction coefficient (k) corresponding at least to VC/cosL to send it to the pat 14. The part 14 multiplies the signal dlambda/dt received from the part 11 by the coefficient (k) received from the part 16 to correct the guide signal dlambda/dt corresponding to the factor dlambda/dt. Then the corrected guide signal kdlambda/dt is sent to a steering part 12. Thus the guide signal is corrected in response to the relative speed between the flying object and the target. As a result, the proportional navigation is always secured with the flying object regardless of the change of the flying object or the target.

Title: Temperature control system in copying machine
Inventor: HOSAKA MASAO
IPC: G03G15/20
Filed: 1980-04-14
Abstract: PURPOSE:To control the temperature of a fixing device highly accurately by changing an electric power supplying control system according to the difference in the operating state whether it is under standby or exposure. CONSTITUTION:Upon turning to ON of a main switch, the maximum electric power is supplied to the lamp of a fixing device so that temp. is raised rapidly period T1). Thereafter, the temp. of the fixing device is controlled by a temp. detecting element by turning the power source to ON and OFF until it reaches 200 deg.C (period T2). During standby, the exposure lamp is not lighted, therefore there is no fear for noise to be given thereto, hence, the power source of the fixing lamp is pulse-width-controlled (put on and out at every certain cycles) (period T3). During exposure, electric power is used for the exposure system and therefore the power source for the fixing lamp is phase-controlled so as to avoid excessive increase in load as a whole (period T4).

Title: High-frequency heater
Inventor: IWABUCHI YASUSHI
IPC: F24C7/02
Filed: 1979-04-19
Abstract: PURPOSE: To enhance the thermal efficiency by stopping a blower used for cooling a high-frequency oscillator during steam cooking and oven cooking, and to prevent too early stopping of a heater by rotating the blower during grille cooking.  
     CONSTITUTION: In cases of steam cooking and oven cooking, food 11 in a heating chamber 3 is heated by the heat coming from the surroundings thereof. In these cases, little of the heat energy in the interior of the chamber 3 escapes to the exterior through the peripheral walls of the chamber 3 because a blower 4 is not operating; therefore, cooking can be conducted at high thermal efficiency. In the case of grille cooking, the blower 4 is rotated, thereby preventing too early stopping of an upper heater 5 for grille due to the action of a temperature regulator, increasing the discharge amount of infrared energy and sufficiently scorching the food in a shorter time period.

Title: Membrane switch
Inventor: KOBAYASHI IKUO
IPC: H01H13/702
Filed: 1988-03-01
Abstract: PURPOSE:To prevent malfunction of a membrane switch even if deformation is concentrated in the neighborhood of a contact section and to use the switch stably in a long time by forming insulative projections in a hole of a spacer as being projected higher than the area where a contact electrode and the portion which faces the contact electrode with certain distance have same level on the surface of the contact electrode and the side of the hole. CONSTITUTION:For instance, a plural number of insulative projections 7 are arranged on the surface of a electrode sheet 1 in the hole 4 of a spacer 3 as being higher than the surface of a contact electrode 2. When the electrode sheet 1 is bent and projected in the direction where a contact faces, by supporting a portion having moderate slope with the insulative projections 7, the portion of the contact electrode 2 which is bent and hung down is also supported so that touching of the contact is prevented. When the electrode sheet 1 begins to be bent and hung down, the electrode sheet 1 touches the insulative projections 7 to be supported between the neighborhood of the side of the hole 4 and the portion where the contact touches so as to keep high resistance until the contact touches the portion. Accordingly, malfunction of a membrane switch is prevented even if deformation is concentrated in the neighborhood of the hole 4 of the spacer 3 and the switch is stably used in a long time.

Title: Light marker and emission source therefor
Inventor: JO KAZUHIKO
IPC: G01C15/02
Filed: 1997-02-17
Abstract: PROBLEM TO BE SOLVED: To improve the visual recognition and sight effect of a light marker and to extend light nearly permanently and make compact and reduce weight by using the electroluminescence EL emission source of a narrow wavelength distribution region and a fluorescent source that is excited by its emission of light and achieves re- emission at a wider wavelength region. SOLUTION: Light at a narrow wavelength region has a high brightness and has a high visual recognition effect in terms of the visual recognition of the presence of an image, while light at a wide wavelength region has a high intensity and improves a sight effect in terms of the visual recognition of an image contour without being affected by the color state of a reflection surface. Each emission source 9 has an input side electrode 11 and an output side electrode 12 and is driven by a DC voltage 5V. Also, the calorifit value of the emission source 9 is small, so that the heat emitted from the enclosure 1 is also small and hence emission does not stop and lasts nearly permanently and does not cause thermal disturbance to an experimental system.  When a level surface is the light reception surface of a TV camera, the electroluminescence of an LED with much quantity of light as compared with a laser has less energy loss and hence the generation of heat is smaller as compared with the laser also in this respect.

Filed: 1996-03-06
Abstract: PROBLEM TO BE SOLVED: To attempt to remarkably shorten the testing time of a chip to be tested or the assembling time of a user program by providing the steps of measuring newly write characteristic distribution and deciding the writing time. SOLUTION: The method for inspecting a semiconductor memory comprises the steps of writing data in the arbitrary address of the semiconductor memory to be inspected at a predetermined writing time, evaluating the logic by reading the data, and discriminating the propriety of writing in the address. In this method, the first step 11 of measuring the write characteristic distribution measures the write characteristic distribution of a population including the memory to be inspected. The second step 13 of deciding the writing time sets the writing time to become the writing frequency of about 100% based on the previously measured write characteristic distribution, sets the writing time to a predetermined write time, thereby remarkably shortening the writing time.
