IPC: F16F15/26
Filed: 1989-03-31
Abstract: PURPOSE:To shorten a balancer shaft by installing thereon a balancer weight which is divided into two to the left and right, and fixing one of the divisions to the inner race of the balancer shaft driven gear. CONSTITUTION:A balancer shaft 2 is borne rotatably by two bearings 13, wherein a balancer weight 14 is mounted at one end while a balancer weight 3 and a balancer shaft 2 driven gear 5 are installed at the other end. This driven gear 5 is formed separately from the inner face 6, and the latter named balancer weight 3 is divided into two to the left and right, wherein one of the divisions 4 is fixed to the inner race 6. A spring 15 is fitted between these driven gear 5 and inner race 6, and play between the driven gear 5 and the balancer weight division 4 is adjusted. Accordingly no installation space to the shaft 2 is required at this balancer weight division 4, that allows shortening of the engine width.

Title: Pickup cartridge
Inventor: ONO TSUYOSHI
IPC: G11B3/18
Filed: 1978-07-04
Abstract: PURPOSE: To make it possible to adjust arbitrarily a resonance frequency to reproduce a record with a high precision by bringing a spring material, which can adjust arbitrarily elastic components, into contact with the steel body contacting with a record disc.  
     CONSTITUTION: Steel-body lever 8 is brought into contact with a record disc in parallel with cantilever 17, and the compression force of lever 8 onto the record disc surface can be adjusted by gum 14. Therefore, the value of a resonance frequency itself can be varied by adjusting freely the value of SR of an effective stiffness at the view from the contact on the record disc dependent upon lever 8. Consequently, proper resonance frequencies can be set to arms and vibrators having various kinds of characteristic and can be combined to be used, so that this constitution is superior in general purpose property. Thus, the resonance frequency can be adjusted arbitrarily to reproduce the record with a high precision.

Title: Optical fiber testing method
Inventor: FURUHASHI MASAAKI
IPC: H04B10/07
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To provide an optical fiber testing method capable of automatically detecting loss of a connecting point even in case of measured waveform not being observed as a straight line after performing logarithmic conversion to the change of a receive level due to uneven loss distribution of an optical fiber. SOLUTION: A detection starting point of the level change of first signal waveform is set, and a criterion for the level change of the first signal waveform is set. In case the receive level difference data of the head and end of a part continuous with the starting point on the first signal waveform exceeds the criterion, concerned range of the signal waveform are extracted, and the fixed value corresponding to each range on the extracted result is added to generate second signal waveform and to obtain an approximate straight line. A criterion is set on the basis of level difference in the position of a connecting point formed by the approximate straight line.  Whether or not the connection loss value computed on the basis of the first signal waveform exceeds the criterion is judged, and a data point exceeding the criterion is judged to be a discontinuous point of a measured optical fiber.

Title: Transfer device
Inventor: NAKAO HIDEYUKI
IPC: G03G15/16
Filed: 1989-04-03
Abstract: PURPOSE:To obtain a transfer device which does not create central omission even when a cut paper is used by providing an elastic roller electric resistance so as to come into contact with a toner image carrier over the cut paper and rotating the elastic roller at a peripheral velocity different from that of the toner image carrier. CONSTITUTION:A rotating photosensitive body 2 is brought into contact with the elastic roller 3 electric resistance as a transfer roller, the cut paper 4 as a transfer material is carried to a transfer area by a carrying member 5 and the moving speed of the toner image carrier 2 differs from the peripheral velocity of the roller 3. That is, since there are tonner grains on the photosensitive body 2, a friction coefficient between the cut paper 4 and roller 3 becomes higher than that between the cut paper 4 and the photosensitive body 2, and the cut paper 4 moves at the same speed as the transfer roller 3, the speed difference arises between the cut paper 4 and the photosensitive body 2 and the coagulation of the toner grains is prevented. Therefore, a toner image can be transferred to the cut paper without central omission.

Abstract: PURPOSE:To perform the transmission of information with high reliability by classifying the equipments having the transmission terminals into a plural number of emergency levels and then transmitting again the information based on these set levels. CONSTITUTION:A household communication system includes plural equipments having the transmission terminals and these equipments are classified into four emergency levels 1-4 in order of higher emergency.

The retransmission frequency is limited to the equipment of level 3, and the retransmission of information is carried out at random time intervals. The retransmission of information is not performed with the equipment of level 4. In such a constitution, the communication probability is improved at each level and also among the levels. Then the reliability is extremely improved for the transmission of information.

Title: Electricity and light (and) element
Inventor: UMENO MASAYOSHI
IPC: H03K19/14
Filed: 1982-05-15
Abstract: PURPOSE:To simplify a system, by integrating two semiconductor lasers on the same substrate in monolithic structure, and allowing one laser to generate an output with wavelength corresponding to an input signal and the other laser to generate an output only when two inputs are supplied at the same time. CONSTITUTION:Thin film crystal layers of an n type InP layer 5, InGaAsP layer 6, P type InP layer 7, InGaAsP layer 8, and n type InP layer 9 are grown successively on the InP substrate 4; the layers 9, 8, and 7 are peeled off up to their intermediate parts to form electrodes 1 and 3, and an electrode 2 is formed on the substrate 4. When currents I1 and I2 are flowed between the electrodes 1 and 3 (LD31) and electrodes 3 and 2 (LD32), waves having wavelengths corresponding to the band gap energy values of the layers 8 and 6 are emitted. The threshold current of the LD31 does not depend upon the current I2, but that of the LD32 depends greatly upon the current I1. The characterstics of this element are as shown in a figure, and even when a current having the same value is flowed to the LD32, the current density increases at the electrodes to reduce an apparent threshold current. Consequently, two outputs are ANDed.
