Title: Type head
Inventor: OKUNA KENJI
IPC: B41J2/28
Filed: 1983-02-28
Abstract: PURPOSE:To form a spring-energized, easy to manufacture, quality fluctuation eliminating and power saving type head by only constructing a lateral magnetic path ring by means of installing a permanent magnet between 2 planes of accommodating iron core. CONSTITUTION:Between iron cores 5a, 5b, a lateral magnetic path ring 12 composed of permanent magnet 6 and ferromagnetic body thinner than the permanent magnet are inserted. Mutually contacting surfaces of magnetic circuit composing parts (iron core 5a, permanent magnet 6, iron core 5b, armature 2, lateral magnetic path ring 12) are all parallel. Further, when 2 parts are applied onto a single part, these surfaces become the same plane. This kind of construction permits reduction of man-hour figures for production and facilitates location of reference position reducing than dimensional errors and improving working accuracies. As a whole, fluctuation of quality is minimized.

IPC: F02B33/44
Filed: 1984-02-21
Abstract: PURPOSE:To improve the scavenging operation of an engine to enhance the performance of the engine, by forming a plurality of small scavenging holes respectively in right and left cylinder walls, by shortening the length of one of partition walls between the small holes, which is remote from an exhaust hole, by a specific range. CONSTITUTION:Three pairs of small scavenging holes 10, 9, 8 are formed, in the mentioned order from the exhaust hole side 2, on one side of the symmetrical surfaces of the cylinder 1. Further, one partition wall 12 near to the exhaust port 2 among the partition walls between the small scavenging holes 8 through 10 has a long length as is in conventional arrangements, while the partition wall 11 remote from the exhaust hole 2 has a length of 2/3 of the length of the partition wall 12. During scavenging stroke fresh air (scavenging air) is introduced into a scavenging air passage 13 from a crank chamber 5 through a scavenging passage inlet port 14 in a cylinder skirt 3. At this time the scavenging air may be smoothly moved to balance scavenging air pressures since the partition wall 11 is made short. Accordingly, satisfactory scavenging operation may be made to enhance the output power of the engine, and so forth.

Title: Stereo reproducer
Inventor: MOGI NORIO
IPC: H04S1/00
Filed: 1978-03-20
Abstract: PURPOSE:To improve spreading feel and depth feel of listening sounds by adding and mixing left  and right channel signals and making their specified regulation of delay, phase shift and level  thereby forming artificial indirect sounds. CONSTITUTION:The mixed signal of left and right channels by a mixer 1 is delayed for the time  tau1 corresponding to the path difference between the distance (a) from the listening point P up to  the sound image localization position I and the distance (b) from the position I up to the  reflection point of the wall B by a delay circuit 2 and is then made to the artificial indirect sound  signals of direction -xsi1 of sound pressures PL, PR for the left and right ears of th listener of a phase  difference theta and amplitude ratio X based on formulas I, II by phase shifters 3, 4 and level setters 5, 6. At the same time, the artificial indirect sound signals from the direction xsi2 are formed in the  similar manner and when these artificial indirect sounds and the left and right channel signals are synthesized in adders 14, 15 and the synthesized signals are applied to speakers, these are received as the sound image of the fixed point further from the point P and those corresponding to the  reflected sounds through reflection of the wall at a far distance, thus even in a narrow room the  listened sounds have increased spreading and depth feel. Here, gamma denotes the attenuation constant  by head diffraction and PO the reference sound pressure of the indirect sounds.

Title: Composite controlling amplifier
Inventor: TAKAGI SHIYUN
IPC: H03G3/12
Filed: 1982-02-26
Abstract: PURPOSE:To prevent pulse noise generated at the switching of plural controlling amplifiers, by controlling an amplifier to be controlled with the controlling amplifiers. CONSTITUTION:A saturated current IS1 is flowing to the controlling amplifier 1. When an input voltage V2 to a controlling amplifier 2 is reduced, an output voltage V0 is increased. Since the output voltage V0 is fed back to an inverting input of the amplifier 1, an input voltage V1 of the amplifier 1 is increased and the IS1 begins to reduce. The IS1 is reduced slowly with a stored charge of a capacitor C4 (not shown in figure). As a result, an equivalent input voltage to the inverting input of the amplifier 1 is increased more than that without the  capacitor C4. Thus, the amplifier 1 is made controllable quickly and the pulse  noise being the input voltage V1 or below is generated. Thus, the pulse noise  generated at the switching of the controlling amplifier is prevented.

Title: Parallel operation for telephone device on digital loop
Inventor: ROORENSU JIEIMUZU RETARATSUKU
IPC: H04Q5/00
Filed: 1982-02-27
Abstract: Disclosed is a digital station apparatus, such as a digital telephone set, capable of being operated in parallel on a subscriber's digital loop (e.g. in an extension mode) without the need to route all the PCM signals to common equipment. Only one of the parallel sets is active at a time; all the others are passive. In the passive state the telephone set receives only, and does not transmit. It monitors its own signal magnitude relative to the signal magnitude produced by the active "extension" on the same digital loop. When its own signal magnitude has satisfied a comparison criterion, then that passive set becomes active and both transmits and receives, while all other sets on the loop are passive.
