Title: Waveguide type optical polarized wave separating device
Inventor: SEKI MASAFUMI
IPC: G02B6/126
Filed: 1990-06-14
Abstract: PURPOSE:To separate input light beam into two each orthogonal polarized light with high isolation and low loss by constituting the device of a polarized wave separating device which utilizes a difference of coupling length of a TE mode and a TM mode of a waveguide type directional coupler, and a polarizer placed on the way of two pieces of output waveguides of the same device. CONSTITUTION:The device is constituted of polarized wave separating devices 11, 12 which utilize a difference of coupling length of a TE mode and a TM mode of a waveguide type directional coupler, and polarizers 3, 4 which are placed on the way of two pieces of output waveguides 15, 16, respectively of its device and have an azimuth conforming to a polarized light of a predominant mode propagated along the output waveguides 15, 16. When light of no- polarization is inputted to an input waveguide 10 of this device, light consisting of only almost the TM mode is outputted from one output waveguide, and from the other output waveguide, light consisting of only almost the TE mode is outputted. In such a way, the inputted light beam can be separated into two each orthogonal polarized light with high isolation and low loss, and accumulation to other device, for instance, the directional coupler can be executed.

Filed: 1988-06-24
Abstract: PURPOSE:To reduce the amount of data to be transmitted by supplying a block on which dummy data is attached on one side and the block in which no dummy data is included on the other side to the encoder of an error correction code selectively, and transmitting the output signal of the encoder from which a redundant code is eliminated. CONSTITUTION:Out of a first block and a second block with different size, the dummy data is attached on the block on one side with a fewer amount of data, thereby, the first and second blocks are set as the ones of same size. The dummy data is set so that at least part of the system of the error correction code can be generated by the dummy data, and the block on one side on which the dummy data is attached and the block on the other side in which no dummy data is included are supplied to the encoder 15 of the error correction code selectively. Then, the output signal of the encoder 15 from which the dummy data and the redundant code formed only by the dummy data are eliminated is transmitted. In such a way, it is possible to omit the transmission of not only the dummy data but part of check data, and to reduce the amount of data to be transmitted.

IPC: B41J15/04
Filed: 1992-06-16
Abstract: PURPOSE:To utilize heat energy dissipated from a control section effectively by transmitting the heat generated in a printer control section to a roll paper holder by means of a fan. CONSTITUTION:A thermal paper 3 fed from a roll paper 2 on a roll paper holder 1 is drawn from a drawing section 5 into a printer section 4 and ejected by an ejection section 6. During the period, printing is carried out by heat energy in a thermal head 7. The heat energy from the thermal head 7 is controlled by a printer control section 10 based on the temperature of the thermal paper 3 measured by a temperature sensor 8 mounted on the position of the thermal head 7. The head of the temperature control section 10 generated at that time is transmitted into a roll paper holder 1 by a fan 9, and the roll paper 2 is heated. The temperature of the thermal paper 3 to be fed, therefore, rises and the energy applied to the thermal had 7 can be lowered.

Patent JP-S5857747-A (JP)
Title: Semiconductor device
Inventor: YOSHIKAWA TOSHIBUMI
IPC: H01L29/74
Filed: 1981-09-30
Abstract: PURPOSE:To improve a critical OFF voltage increase rate of a vertical type photo silicon controlled rectifier (SCR) by making large hFE of pnp element and photo sensitivity by thermal treatment, while making small a gate resistance and by integrating elements in the same chip. CONSTITUTION:Response of pnp element of photo SCR delays when hFE is made large, while gate resistance RG and gate voltage VG are in the relation VG  CRGXdv/dt, and when RG is made small, a critical off voltage increase rate becomes large. Meanwhile, a displacement current by dv/dt is a transient phenomenon and therefore (dv/dt)M can be improved fantastically by making large hFE and small RG by a mutual reinforcing effect by these two effects. When hFE is increased by making longer the life time of base layer, a photo sensitivity is generally enhanced, while the minimum trigger current reduces a little and the (dv/dt)M is as much improved. Such photo sensitivity is improved by about 30% through annealing under the N2 atmosphere at 900 deg.C. When the RG 9 (P layer) is provided in the substrate 1 and the one end is connected to the gate 4, while the other end to the cathode 8 through the electrode 10, the (dv/dt)M can be improved by 2-3 times as compared with that when a resistor is provided externally.

Abstract: PURPOSE:To prevent an alarm sound from reaching an opposite talk party by constituting the alarm sound in a telephone call with a voicing signal which is generated at specific intervals and attenuating or cutting off the output of a microphone in synchronism with the voicing signal. CONSTITUTION:The voicing signal (c) is outputted from a 1st gate circuit 21 at specific intervals for a specific time and outputted as the alarm sound from the speaker 11b through a mixer 23. A control signal (d) outputted by a 2nd gate circuit 22, on the other hand, is outputted at the same intervals with the voicing signal (c) for the same time and sent to a muting circuit 24. The muting circuit 24 attenuates or cuts off the output of the microphone 11a only for a period wherein the control signal (d) is outputted. Consequently, when the alarm sound is generated during the telephone talk, the telephone set with the voicing function which prevents the alarm sound from reaching the opposite talk party is obtained.

Title: Mechanical pencil
Inventor: HENMI TOSHIRO
IPC: B43K21/22
Filed: 1997-05-30
Abstract: PROBLEM TO BE SOLVED: To only press a lead to a paper face so that the lead is rotated and thereby, eliminate the one-sided wear of the lead to form a writing line of constant width by providing a chuck for holding and releasing the lead in a shaft barrel and at the same time, arranging a rotary means for rotating the chuck through the backward movement of the lead. SOLUTION: A lead L is pressed to a paper face slightly strongly when the writing tip of the lead is thick due to the uneven wear of the lead during writing. Consequently, a chuck ring 4 moves backward by a pressing action through a chuck 3 holding the lead L. In addition, following the backward movement of the chuck ring 4, a sliding element 8 recedes to cause even a rotor 15 to move backward. As a result of this receding action of the rotor 15, the protrusion 17 of the rotor 15 reaches the top of a longitudinal protrusion 12 of a cam part 11, and slides down rotating over the inclined plane 14 of an adjoining longitudinal protrusion 12.  The rotation of the rotor 15 is triggered by the engagement between the protrusion 10 of the sliding element 8 and the inclined plane 18 of the rotor 15, and next, the rotor 15 is caused to rotate by the engagement between the inclined plane 18 and the inclined plane 14.

Title: Leakage detector for easy-to-open canned goods
Inventor: KOMURO MASANORI
IPC: B65D17/00
Filed: 1987-06-26
Abstract: PURPOSE:To eliminate the error in the measurement of the displacement amt. of caps by unequal directions of opening tabs by unifying the directions of canned goods by a tab stopper lowered by a cam mechanism at the time of revolving the canned goods supplied onto a turn table together with a rotary disk of a main body while rotating the same. CONSTITUTION:The canned goods with the tabs (t) conveyed from a conveyor 2 are supplied by a supply turret 11 onto the turn table 6 and revolve together with the rotary disk 5 of the main body while said goods are rotated by the turn table 6. The tab stopper 8 is lowered by the cam mechanism as the rotary disk 5 rotates. The tabs (t) of the canned goods strike the tab stopper 8 according to the rotation of the canned goods by which the rotation of the canned goods is prohibited. As a result, the canned good slip on the turn table 6 and the directions thereof are unified always in the specified position. The measurement is, therefore, made in the position where the measurement is not affected by the tabs (t) if the displacement amt. of the can caps is detected in the section thereafter. The measurement error by the tabs (t) is thereby eliminated.
