Title: Pll circuit
Inventor: MISAWA MASAYUKI
IPC: H04B7/26
Filed: 1994-04-04
Abstract: PURPOSE:To shorten the time needed for error decision of the start of a lock-up operation and also to totally reduce the variance of time before the lock-up operation is started by providing a switch circuit between a control voltage terminal and a DC power circuit. CONSTITUTION:A PLL circuit is provided with the switch circuits 15 and 16 which are placed between a DC power circuit and the control voltage terminals 5e and 6e of the voltage control oscillation circuits 2a and 3a respectively. When a power supply is turned on or an operation is started, the circuits 15 and 16 connected to the terminals 5e and 6e which control the frequency of the circuits 2a and 3a are turned on. At the same time, the control is carried out so that the change of frequency is maximized for both circuit 2a and 3a. Thus it is possible to shorten and also to reduce and stabilize the variance of time before a lock-up operation is started. When the lock-up operation is started, the circuits 15 and 16 are immediately turned off by a control means. Meanwhile the power supply and the external noises lose their paths to the circuits 28 and 3a Thus the PLL circuit can operate with high stability.

Title: On-vehicle speaker system
Inventor: KATOU SHIGEKI
IPC: H04R5/02
Filed: 1984-04-28
Abstract: PURPOSE:To obtain a rich low frequency reproduction always without damaging a low-frequency by providing a means for transmitting only a low frequency of an audio signal and supplying a pair of speakers excellent in a low frequency reproduction characteristic through a variable resistance. CONSTITUTION:Audio signals are inputted to terminals Lin and Rin. A cut-off frequency of an LPF16 passes frequency below low frequency sounds of 100- 150Hz less of an upward directional feeling in terms of acoustic sense, while HPFs 2 and 6 passes the frequency band which will not be passed by the LPF16. For instance, when sliding pieces 1', 5', 9' and 12' are slid in the direction as shown in C, in variable resistances 1 and 5, reproduction sounds from front speakers 4 and 8 become smaller, because audio signals from right and left speakers 4 and 8 are attenuated, and reproduction sounds covering an entire band from rear speakers 11 and 14 are emphasized. When the sliding pieces are slid in the D direction, high frequency is reproduced from the speakers 4 and 8, whereas outputs from the speakers 11 and 14 will not be reproduced.

Title: Printer
Inventor: NISHIWAKI MANABU
IPC: B41J2/365
Filed: 1986-04-16
Abstract: PURPOSE:To prevent the disturbance of print due to a disturbance of temperature by providing means for detecting the temperature near an ink heating portion under printing, a variable power source connected to a plurality remaining heat electrodes contacting a resistive layer and a control mechanism for varying the voltage of the variable power source based upon a signal fed from the temperature detecting means. CONSTITUTION:A control section 102 detects the temperature of a temperature detecting means 57 and sets the output of a variable power source 103 so as to apply a voltage to between remaining heat electrodes 100, 101 thereby a current flows through a resistive layer 14 between said electrodes 100, 101 thus heating the resistive layer 14. The temperature near a recording portion is maintained at a preset level through said feedback loop where said temperature is set to a level higher than the maximum level to be predicted by considering an environment temperature, accumulation of heat in a recording head, etc. while lower than the active temperature of ink. Consequently, variations in printing density due to the disturbance of temperature such as variations in environmental temperature, accumulation of heat in the recording head, etc. can be prevented by means of a relatively simple mechanism without requiring a heat producing mechanism such as an independent heater.

Title: Preventive mechanism for discrepancy in tuning of push-button tuner
Inventor: NISHIKAWA YASUHISA
IPC: H03J5/12
Filed: 1978-07-21
Abstract: PURPOSE: To eliminate discrepancy in tuning by stabilizing a fitting relation to a crossbar, by employing a linear connection between the pivot hole of a frequency normalization member and a pivot.  
     CONSTITUTION: Pivot 5 is set at taper part 5a in pivot hole 3a formed at the base edge part of frequency normalization member 3. Consequently, a linear connection is possible and even if an airtight connection is made, the setting-angle adjustment of member 3 is also possible, causing no play with a stable fitting relation to the crossbar. Further, setting pin 4 has conic taper part 4a formed and in channel selection, this taper part connects to connection edge 1a of operation link 1 to insert and extract the core into and from the coil via slide member 12. As a result, member 3 is pushed against crossbar 2 at taper part 4a to prevent the tip part of member 3 from floating, thereby preventing the discrepancy in tuning.
