Title: Method for measuring electrical length of coaxial cable
Inventor: ADACHI YOSHIO
IPC: H01B11/18
Filed: 1985-09-27
Abstract: PURPOSE:To discriminate whether a min. point is the even-numbered point or odd-numbered point by short-circuiting the terminal of a coaxial cable and measuring standing waves by a slotted line with prescribed frequencies (f) and f/2. CONSTITUTION:An oscillator 1B, an attenuator 2, the slotted line 3, the coaxial cable 4 and terminal short-circuit fitting 5 are connected in series. Namely, the terminal of the cable 4 is short-circuited. An electric signal of the prescribed frequency (f) is applied from the oscillator 1B to the cable 4 in this state, then the progressive wave are totally reflected by the fitting 5 via the attenuator 2, the line 3 and the cable 4. When the reflected wave returns to the oscillator 1B, the progressive wave and interference wave interfere with each other to generate the standing waves 6. The three min. points of the waves 6 are measured and the positions thereof are preliminarily recorded. The frequency of the oscillator 1B is then converted to f/2 and the standing waves 7 are measured. The min. point and max. point thereof are measured and recorded. The 2-period length of the waves 6 of the frequency (f) coincides with the 1-period length of the waves 7 of the frequency f/2 and therefore, whether the min. point is the even-numbered point or odd-numbered point is discriminated.

IPC: H01M4/06
Filed: 1983-11-16
Abstract: PURPOSE:To eliminate adverse effect caused by cutting burr and increase workability by press-bonding a soft metal plate on a belt-shaped current collector comprising a punched metal having a no-hole row in its upper end and cutting it in a desired width. CONSTITUTION:A belt-shaped current collector 6 comprising a punched metal having a no-hole row 7 in its upper end is used and a lithium plate 2 is press- bonded on the current collector 6 so that the plate 2 covers whole part of the current collector other than the upper part. The current collector 6 is cut along the line b-b' in a desired width to obtain a lithium electrode. A current collecting pin 3 is welded on the upper end of the current collector 6. Since the current collecting pin 3 is welded on the no-hole row, cutting burr does not expose from the periphery of the electrode, adverse effect caused by cutting burr is eliminated, and workability is improved because of no complicated process.

The effusive preparation may have a multiple bag structure composed of plural water-permeable bags. The preparation of the multiple bag structure is obtained by housing a medicine in a water-permeable bag, storing a masking agent in another water-permeable bag so that the bitterness of the medicine may be alleviated.  Repelling components to be formulated are individually housed or retained in water-permeable bags, respectively to improve the stability of the active ingredient. The water-permeable bag may be housed in an openable and closable outer bag having gas barrier properties.

IPC: F24C3/10
Filed: 1984-10-16
Abstract: PURPOSE:To contrive to perform the steady igniting by a method wherein a pilot flame generated by an igniting device arranged at the outdoor is introduced to a main burner via a guide plate. CONSTITUTION:A pilot flame generated by an igniting device 6 is introduced toward a pipe burner 1 by an igniting guide plate 4. Then a part of the pilot flame is directly contacted with a main flame hole line 2b for igniting. However, at the reigniting operation after the gas burning in a relatively airtight room, as a housing is filled with an excessively turbulent exhausted hot gas flow, the exhausted hot gas flow along the guide plate 4 is escaped upward from a cut-off hole 9 arranged on the upper surface of the guide plate 4 by the draft effect thereof. Accordingly, the pilot flame is extended enough toward the pipe burner 1, thus, the igniting is performed.

Title: Transmission distortion eliminater
Inventor: MOROMOTO HIROYUKI
IPC: H04N5/21
Filed: 1989-08-23
Abstract: PURPOSE:To enable tap coefficient correction which is fast in converging speed, stable, and hardly affected by noise by performing proportional control in the beginning of a tap coefficient and then performing constant-increment control when the number of times of the tap coefficient correction reaches the specific number of times. CONSTITUTION:A tap coefficient correction frequency counting means 15 counts the number of times of tap coefficient correction by a proportional control type correction arithmetic means. A control means 12 obtains a cancellation signal by performing the tap correction by the proportional control type correction arithmetic means in the beginning of the tap correction and then performs the tap correction by a constant- increment control type correction arithmetic means after the counted value of a tap coefficient correction frequency counting means 15, i.e., the number of times of the tap correction under the proportional control reaches the specific value. Thus, the proportional control is employed in the beginning of the tap correction and then switched to the constant-increment control to securely remove transmission distortion without being affected by a noise. Consequently, the fast convergence and high stability of the proportional control and constant-increment control are obtained and while residual distortion is reduced, the convergence time is shortened, so that stable continuous operation becomes possible.
