Title: Information recording and reproducing device
Inventor: KASHIWAGI YASUHIRO
IPC: G11B7/09
Filed: 1988-05-26
Abstract: PURPOSE:To contrive the subject device which is superior in antivibration with an improvement in reproducing performance on a scratched disk by providing an angle detector or a displacement detector for detecting a vibration and promoting a loop gain of a servo system only when the vibration is given more than a specific value in amplitude. CONSTITUTION:When some impact is given to a housing body, a light quantity being incident upon a photodetector 22 is converted into an electric signal to be inputted to an angle detecting circuit 24, and only a frequency component required for following by a servo mechanism is passed by a filter 27, and then the size of the vibration which is required to be dealt by improving the loop gain of the servo is decided by a comparator 28. When the amplitude of a vibration waveform in an output of the filter 27 exceeds a threshold value in the positive direction or the negative direction, the output is sent from the comparator 28. A signal of logic '1' is outputted for a prescribed time T from the first rising time of this output by a logic circuit 29. This becomes control signals 25 and 26. By this method, even when the disk 1 has a flaw, the good following can be performed without any track jumping and against a positioning error due to the vibration.

Title: Adjusting method for electrostatic charging potential of electrophotographic device
Inventor: YOSHIDA MASAHIKO
IPC: G03G15/02
Filed: 1986-06-05
Abstract: PURPOSE:To easily and accurately obtain the specific electrostatic charging potential of an before-exposure part more than when the thickness of a photosensitive layer is used as a reference and to obtain an image of superior picture quality by using electrostatic charging ability as the reference. CONSTITUTION:A photosensitive body 1 which rotates as shown by an arrow is corona- charged with a specific applied voltage of, for example, 6.8kV by an electrostatic charger 2. Its electrostatic charging potential Vs is measured by a potential probe 3 at a position corresponding to the before-exposure part of a copying machine and the current ISe conducting to the photosensitive body at this time is detected by a sensor 5, thereby knowing the electrostatic charging ability ISe/Vs of the photosensitive body. The electrostatic charging potential of before-exposure part of an electronic photographic device and the electrostatic charging ability of the photosensitive body have high correlation. For the purpose, the electrostatic charging potential of the photosensitive body is adjusted more easily to a specific potential by setting the output of the high voltage power source based on the charging ability of the photosensitive body which is measured and evaluated previously than by adjusting the output of the high voltage power source based on the film thickness of the photosensitive body.

Title: Manufacture of motor housing
Inventor: GOMYO KAZUO
IPC: H02K15/14
Filed: 1999-05-12
Abstract: PROBLEM TO BE SOLVED: To lessen the influence on other parts caused by burrs to the utmost, by putting in a crushing process for crushing the vicinity part of a die-cut section, between a narrowing process and a cutting process. SOLUTION: After a narrowing process, a die 41 at the vicinity part of the die-cut section of an abutment face 4a at which a yoke housing 6 abuts on the end housing 7 being other parts is provided with a projection 41a, and a crushing process is performed with a punch 31. Next, the cutting process by a punch 32 and a die 42 is performed. At this time, cutting the yoke housing 6 while pressing it with a knock out 20 will make burrs 61b small. Consequently, though the die-cut section is crushed in the crushing process even if the board thickness is not fixed due to delicate corrugation of the yoke housing 6 or inequality of material quality, the burrs 61b, if any occurs, will occur apart from the abutment face 61a. Therefore, there is no influence at the time of its abutting on the end housing.  That is, this manufacture can prevent the compulsory setup of a rotary shaft caused by the backlash of the yoke housing 6 or the tilt of the yoke housing 6.

Title: Control device of internal combustion engine driven heat pump
Inventor: IMOTO SEIJI
IPC: F02D29/04
Filed: 1986-06-05
Abstract: PURPOSE:To prolong the operation time of the heat pump to make gentle the change in the room temperature and to reduce the number of times of starting and stopping the heat pump by setting the operational speed of the engine at a minimum speed, regardless of the temperature deviation in a case where the preceding operation time is shorter than a preset reference time and determining the operation time at the minimum speed in accordance with the duration of the preceding operation time. CONSTITUTION:A target rotational speed Nt of the heat pump is determined from a deviation dT between the room temperature and a preset temperature value. The target rotational speed Nt is stored in a ROM 13. The preceding operation time t3 is compared with a preset reference value T2. When t2 is greater than T2, K normal control is carried out. When t2 is smaller than T2, the target rotational speed Nt(n) is set to a minimum speed, and simultaneously the operation time T1 is determined. The relationship between the preceding operation time t2 and the operation time T1 at the minimum speed is stored in the ROM 13. The operation time t1 at this time is calculated, and the set rotational speed Nr is operated from the target rotational speed N(n) thus determined. Further, the set rotational speed Nr is compared with the map data stored beforehand and an electronic governor set voltage Vr is obtained, and this voltage is output to an electronic governor 5 to carry out the speed regulation.
