Title: Measuring device for walk distance
Inventor: ICHIKAWA SHINGO
IPC: G01C22/00
Filed: 1986-09-17
Abstract: PURPOSE:To measure a walk distance easily and accurately by calculating the walk distance through the intermediary of a counter which is controlled to start and end counting in synchronization with the transmission and reflection of an ultrasonic wave by a main body and a reflector put on the leg respectively. CONSTITUTION:An ultrasonic wave is transmitted from an ultrasonic speaker- microphone 2 of a main body 1 put on one foot and is reflected by a reflector plate put on the other foot, and a received reflection wave signal is detected by a reflection wave detecting circuit 25. The start and the end of counting by a distance counter 33 are controlled through the intermediary of FF 31 which operates synchronously with and responsively to the detection signal of the reflection wave of the transmitted ultrasonic wave. Then the maximum value is determined as a pace distance of one step by a scaled-up data judging circuit 40 from the count value of the counter 33 which increases and decreases gradually. It is integrated by an integration circuit 50 provided with an addition circuit 51 and others, and a walk distance is measured therefrom. By these devices, the walk distance is measured easily and accurately only with the process to put them on ankles or shoes.

Filed: 1984-10-18
Abstract: PURPOSE:To maintain the surface potential of a photosensitive body at good level so as to perform excellent printing in which the brightness is uniform, by constituting an electrophotographic device in such a way that, when the surface potential of the photosensitive body immediately after a charging section is charged is too high, the high pressure level is lowered and, when the surface potential is too low, the high pressure level is raised.

Title: Jointing device for rain shutter door panels
Inventor: YOKOYAMA SHINJI
IPC: E05C7/04
Filed: 1993-08-11
Abstract: PURPOSE:To ensure the easy storage of door panels by jointing adjacent door panels to each other via a cord of such length as allowing the superposition of both panels. CONSTITUTION:The front and rear ends of a door panel 1 are fitted respectively with a pulling unit 21 such as a take-up reel and a coupler 22. Furthermore, the forward end of a cord type material 2 led out from the pulling unit 21 is jointed to the coupler 22 of an adjacent door panel 1, and the length of the cord 2 is so made that a gap between the panels 1 is approximately equal to single panel breadth. As a result, when the first panel l is fed into a door receptacle 3, the cord 2 is extended and the second and succeeding panels 1 are not pulled. Also, when the second panel l is fed into the receptacle 3, the third panel 1 is pulled as soon as the gap thereof from the second panel 1 becomes equal to single panel breadth. Then, upon the storage of the second panel 1, the third panel 1 travels to the feed position of the second panel 1. Similarly, succeeding panels 1 are fed into or taken out of the receptacle 3. According to this construction, the panels 1 can be fed without applying a force near the receptacle 3. Also, the cord 2 can be prevented from being slackened, and the release of the coupler 22 is not required, different from the conventional case. Thus, a panel feeding work can be easily undertaken.

Title: Burner
Inventor: SASADA KATSUMI
IPC: F23D14/62
Filed: 1982-12-14
Abstract: PURPOSE:To stabilize the flame only at burner ports regardless of the change of air quantity in premixture and consequently continue stable combustion by a method wherein secondary air is supplied uniformly throughout the whole periphery of the flame formed at the burner ports. CONSTITUTION:Gas supplied through a fuel supply port 2 in a premixture chamber 4 and primary air supplied through primary air supply holes 7 therein are mixed with each other in order to produce premixture in the premixture chamber 4. After that, the premixture is supplied to burner ports 5 so as to form flame 8 to burn there. The supply of secondary air to the flame 8 is performed by two kinds of air streams or by a secondary air stream C, which is supplied through a gap 14 to the root of the flame 8, and a conventional secondary air stream A, which is supplied through secondary air holes 10 to the top of the flame 8. Consequently, the diffusing surface of the premixture jetted through the burner ports 5 and the secondary air is formed between the burner ports 5 and the gap 14 and consequently no heating and thermal deformation on a partition plate 9 is resulted. And yet, no pressure drop in an outer peripheral air passage 6 occurs and as a result stable combustion can be continued, because the magnitude of the gap 14 does not be changed or is kept constant during combustion.

IPC: G11B23/50
Filed: 1991-08-30
Abstract: PURPOSE:To inexpensively and easily provide the cleaning cloth which can remove the electrostatic charge on an optical disk surface. CONSTITUTION:A material exhibiting a work function within a + or -0.13eV range of the work function of the surface layer material on at least the recording surface side of the optical disk is used as the cleaning cloth for the optical disk for the purpose of wiping away the stains on the surface of the optical disk.

The number of the times for the wiping operations by the cleaning cloth is drastically decreased as compared to heretofore and further, the foreign matter, such as dust, hardly sticks to the surface of the optical disk and, therefore, the generation of troubles at the time of recording and reproducing of the optical disk is exceedingly prevented.
